Chimney for a sauna stove made of bricks. Let your stove "breathe" easily: installation for a chimney bath from a chimney

For quite a long time, stoves were deprived of chimneys, which is why our ancestors had to take bath procedures “in a black way”. Today, such problems do not exist, so being in a steam room brings more positive emotions. Now anyone who has managed to build the bath itself can install a chimney for a bath, because it is not difficult if all the rules are observed - below, in fact, we will describe how to make a chimney in a bath with our own hands - a step-by-step guide is attached.

The installation of a chimney in a bath requires special responsibility, because if even one mistake is made, the correct functionality of the bath will be called into question. It is very important to create all the conditions under which carbon monoxide would under no circumstances be able to penetrate into the steam room. To do this, before starting work, you should outline a plan, including all stages of construction.

What are chimneys

A do-it-yourself installed chimney for a bath can be external and internal. In Russia, you can most often find the second option - it fits perfectly into the architectural style of the steam room, and does an excellent job of saving the heat generated by the stove. External chimneys are usually installed on American farms.

The internal version of the chimney is good in that it has a more efficient draft, and is easier to maintain. In addition, there is no need to insulate such a chimney.

The external chimney is remarkable in that there is no need to violate the integrity of the roof, moreover, it is clear that such a design is safer for the bath itself and the visitors inside. The internal brick chimney in the bath must have a wall thickness of at least 12 cm, while the outer chimney will require a thickness of more than 38 cm.

Variations and designs of chimneys

It is worth considering the arrangement of the chimney in the bath for a wood-burning stove. As a rule, such a design includes a pipe, flanges and connecting components. The main thing is that the finished chimney can withstand high temperatures without releasing harmful compounds at that moment.

In order for the chimney located in the wall of the bath to retain as much heat as possible, it should be placed with a shift inside the room - then the draft will be as efficient as possible. If, for some reason, this goal cannot be achieved, provide for sufficiently thick walls, the width of which is determined based on the ambient temperatures.

For example, if the temperature outside does not drop below -20 ° C, then a wall thickness of 38 cm is sufficient, however, if frosts sometimes fall below the above indicator, then the thickness will have to be increased to 58-65 cm.

If there is more than one stove in the bath, there should be several chimneys to maintain normal draft. Otherwise, a cutting structure is installed at a height of 75 cm. In any case, the inside of the chimney should be as flat as possible so that a minimum of soot accumulates on it.

The simplest design of the chimney

Installing a chimney in a stainless steel bath is the simplest type of chimney.

For the design you will need:

• galvanized knee 20 × 120 cm - 1 pc;
• galvanized knee 16 × 120 cm - 2 pcs;
• stainless steel knee 16 × 10 cm - 3 pcs;
• tee 16 cm with a plug - 1 pc;
• fungus 20 cm - 1 pc.

To understand how to properly make a pipe in a bath, you will need to do the following work. The pipes are fastened with self-tapping screws, a hole of 16 cm is made in the slab. At the installation site of the chimney, within 15 cm, soft roofing material with thermal insulation is temporarily dismantled from the roof.

The part of the pipe that will protrude into the street is wrapped with basalt wool and asbestos cord to fill the width of the hole made. Next, a pipe lubricated with bituminous mastic is put on, which will be attached with a 20 cm overlap. At the junction of the pipes, to prevent precipitation from getting inside, an asbestos cord is wound.

Chimney installation methods for various stoves

Brick is now increasingly used in the manufacture of chimneys for baths. Although both brick and stainless steel have their positive and negative qualities, their installation is somewhat different.

Installation of a chimney to a steel furnace

The installation of the chimney is started after the installation of the furnace. The process begins by connecting a few supports with the clearances needed to install wider asbestos or sandwich pipes - they have increased fire resistance. Although, it is still undesirable for open fire to fall on them. In this regard, before the first knee, a steel pipe is installed in the bath, and after that - a sandwich pipe.

Lastly, a protective cone against precipitation is installed on the upper end of the chimney. The lower part of the pipe is closed, as a rule, with a plug, through which in the future it will be possible to drain the collected condensate and clean the inner surface of the chimney.

Fixing a chimney to a brick stove

The scheme for installing a chimney for a bath on a brick oven is also simple, and all work can be done by hand.

The construction of the chimney begins after laying the last brick row of the stove - often this corresponds to the 12-19th row, when the upper level of its side doors is reached.

Somewhere on the 21st row, two channels are created, the size of which is equal to one brick. Then they will merge into one channel. At this stage, three quarters are added to the right in order to cover the free space above the core. You will get a gap between the main masonry and the core of 2-3 cm.

The voids are filled with mineral wool. The 22nd row will completely cover the core, and you can move on to shifting the channels to the central part. So that after a while cracks do not form on the floor, an additional row of bricks can be laid above the core.

The narrowing of the chimney is carried out on the 23rd row. Laying is carried out in five. At this stage, valves are installed - first one, and the second - through the row. Further, the type of masonry gradually changes to fluff.

When doing all the work on installing a pipe for a bath with your own hands, make sure that no cracks form, as condensation may appear in such places in the future. Also, don't take larger diameter pipes than required, as the gas will not be able to rise at the proper rate and it will cool faster.

Installation of a finished chimney for a bath

Naturally, there are also ready-made chimneys. They are easier to install, and it takes much less time to do so. In this case, it is also important to do everything as correctly and efficiently as possible, especially if you are doing all the work without anyone's help.

Whatever the chimney, its installation is carried out so that it protrudes exactly half a meter beyond the building. At the junction of the roof and the pipe, you will need to make an “otter”, thanks to which precipitation will not get inside.

It is worth noting that the appearance of soot on the walls after some time indicates poor installation of the chimney. In this case, it will be necessary to identify the resulting gaps as soon as possible and eliminate them.

Cleaning the chimney from pollution

Among other things, it is necessary to provide a list of measures for the timely cleaning of the chimney. It is best if it is a mechanical method. For cleaning, you will need brushes, a special load, and even a sledgehammer with a crowbar. This process is very dirty, so it is advisable to take out everything that is possible from the bath, and cover the rest of the things with something, such as plastic wrap.

The easiest way to operate is with a brush - it is inserted into the chimney, and is slowly pushed up and down until the movements begin to become more and more easy.

If you notice that small accumulations of soot have begun to appear on the pipe, they can be removed by heating the stove with aspen wood. In the process of burning, a huge thrust arises, which carries the ashes out of the pipe. In addition, when the aspen burns, a strong heat appears, due to which the resins in the pipe instantly burn out. Potato peels are considered no less effective, the main thing is to prepare them in sufficient volume.

However, the latest methods of cleaning with chemicals are gaining more and more popularity. They also effectively carry away all the soot and eliminate build-up. It is worth noting that it is better to clean the chimney after rain.

So we learned how to make a chimney in the bath through the ceiling, while making a minimum of effort and time. With proper timely care of the pipes, firewood will always give maximum energy, keeping the temperature at the proper level, and delighting you and your loved ones!

Internal structures

One of the advantages of such a system

External chimneys

1. The chimney will not heat the steam room, which will significantly increase the consumption of wood fuel.
2. The pipe located on the street must be carefully insulated, otherwise the rapidly cooling exhaust gas will not have time to go outside. In this case, the chimney system will need to be cleaned frequently.

There are combined chimneys, which are a metal pipe installed on a wood-burning stove. The design is displayed in the brickwork built into the surface and rises to the required height.

Materials for manufacturing

by the most popular materials for the chimney of a wood-burning stove in the bath are bricks and metal.

brick structures

This is the most common and at the same time labor-intensive version chimney for the stove in the bath. The structure is strong, durable and has high thermal insulation properties. A bath with a brick chimney is most protected from fires. The only disadvantage of the brick system is its rough inner surface, due to which there is a need for frequent cleaning.

Metal chimney

Metal construction is easier install on wood stove and get her out of the room. The disadvantage of metal pipes is the need to create high-quality thermal insulation and the formation of condensate on the inner walls.

When constructing a metal chimney, the following nuances of material selection should be considered:

The easiest way to install a chimney

With the help of a stainless steel pipe, you can make and install the simplest and cheapest chimney structure for a bath. In addition to pipes, you will need to prepare the following elements:

Installation of an external chimney

1. The entire structure of the chimney rises up and is attached to the wall. It is recommended to install it already assembled. This will make it easier to work at height.

Having fixed the structure to the wall, care must be taken to seal the joints. The vertical pipe must be insulated, and in order to avoid condensation, make insulation.

Since, on which the safety of the structure and the health of people directly depend, there should be no errors and omissions during its installation. Before installing the chimney, it is necessary to study its device in detail.

Chimney device in the bath: types of chimney structures for a wood-burning stove and features of their installation

To remove the products of combustion of fuel, to ensure long-term preservation of heat in the bath and fire safety, a properly arranged chimney is necessary. Therefore, before installing it, it is necessary to find out the main parameters of the chimney and study all the details of installation.

Types of chimneys for a wood stove

Furnace bath chimneys differ according to several criteria. According to the method of installation, they are divided into internal and external.

Internal structures

One of the advantages of such a system is its maximum vertical arrangement, which contributes to good traction. The internal flue provides heating in a steam room and considerably reduces time of its warming up. When installing this design, the cost of wood fuel is significantly reduced.

The disadvantages of the internal system for the furnace include:

Laboriousness in installation. To install the structure, you will need to pierce the ceiling and roof, which reduces the quality of the pipe sealing.

• Fire hazard. When installing a pipe for a bath, you will have to isolate the passage in the ceiling with special heat-resistant materials.
• Difficulty in maintenance and repair.
• High risk of smoke in the sauna room. With a negative impact on the structure and the appearance of cracks on it, smoke will begin to enter the room.

But, despite the listed disadvantages, the heat given off by the chimney installed inside the bath is much more important.

External chimneys

Such designs are an American idea. They are are very popular due to the fact that the chimney system located on the street significantly reduces the risk of fire. When installing an external system, the pipe is connected to a wood-burning stove and exits through the wall. On the outer surfaces of the bath, it is attached using special brackets.

The disadvantages of such structures are:

A hole with a diameter of 16 cm is drilled in the slab, pipes fastened with self-tapping screws. The 16 cm part of the pipe exiting through the roof is wrapped with basalt wool and asbestos cord. An upper pipe is mounted on it by 20 cm, which must be well fixed and treated with bituminous mastic. To prevent precipitation from entering the chimney, an asbestos cord is wound around the upper gap between the pipes.

This is the simplest chimney device in the bath. You can easily do it with your own hands.

Device and installation of a sandwich chimney for a wood-burning stove

Made with new technologies chimney system has a multilayer structure. Her body consists of two pipes of different diameters, which are inserted into each other. Between them is placed a heat-insulating gasket in the form of basalt fiber or mineral wool. These materials are resistant to open flames, high temperatures and are immune to chemicals. They perfectly retain heat and dampen sound waves.

The components of a sandwich chimney include elbows, tees, roof passage elements, a condensate collector, a wall clamp, a support console, a mouth, an inspection tee with a door. When choosing these materials, it is necessary to take into account the features of the chimney device in the bath.

Installing a sandwich chimney

Provide construction safety through surfaces is possible only if all the rules and features of its installation are observed.

Stages of work on the installation of a sandwich pipe:

If the distance between the attic floor and the roof is more than one and a half meters, then an unloading unit must be installed on the attic floor. It consists of installation elements and metal corners that are attached to the legs of the truss system. The unloading unit takes on the loads of the pipe coming out of the ceiling and will prevent lateral vibrations.

• A starter sandwich is installed on the outlet pipe of the wood-burning stove. It must be ensured that the inner pipe at the outlet of the furnace enters the nozzle, and is not located on top of it.
• Pipe sections inserted into each other, places of bends and transitions are additionally fixed with clamps.
• To give stability to the structure and close the outlet in the ceiling, a ceiling groove is installed at the place where the pipe passes through the surface. A passageway is welded to it in the form of a pipe of a slightly larger diameter than the diameter of the sandwich pipe. Mineral wool is placed under the ceiling cut, and the structure is tightly attracted to the ceiling with nails or self-tapping screws.
• In the roofing and the crate, holes are made for the exit of the chimney, which are sealed using a roof penetration. The joints are coated with a special sealant.
• The outlet of the pipe should be half a meter above the level of the roof covering. A fungus is installed at the top of the sandwich chimney.

After the assembly is completed, the protective film will be removed from the pipes, and all gaps and seams will be sealed. For this, a special heat-resistant sealant is used.

Installation of an external chimney

The best option for chimney construction is a stainless steel pipe. When installing an outdoor system, the main condition should be the absence of horizontal transitions. Otherwise, condensate and a large amount of soot will accumulate in the chimney. As a result, there will be no normal traction.

Basic requirements for the installation of an external chimney for a bath:

It is necessary to exclude the contact of gas pipelines and electrical wiring with sections of the structure.

• Pipes are attached to the walls of the house using special brackets, between which the distance should not exceed one to one and a half meters. Other structural elements are attached additionally.
• Each joint between the pipes is clamped with a clamp and treated with a special sealant. This will provide the system with a better seal.
• For convenient cleaning of the structure, it is necessary to provide removable parts or an inspection window.

Installation of an external chimney starts at the bottom of the structure. Each subsequent pipe section is inserted inside the previous one.

Stages of work on installing a metal chimney outside the bath:

• The lower part of the pipe is connected to the furnace nozzle in the bath and treated with a sealant. A collar is put on top. It is necessary to connect the chimney to the branch pipe using a tee, pipe or elbow. It all depends on the design.
• At a height of half a meter from the stove, a hole is made in the wall, through which the chimney is passed through with the help of a passage pipe.
• At the end of the horizontal pipe brought out, a tee is installed, equipped with fasteners for the vertical part of the chimney. The lower outlet is blocked by a plug, which, if necessary, will be removed to clean the chimney.
• Pipes are attached to the walls using special brackets. If the main pipe is heavy, then a knee is installed on the support.
• The entire structure of the chimney rises up and is attached to the wall. It is recommended to install it already assembled. This will make it easier to work at height. Having fixed the structure to the wall, you need to take care of sealing the joints. The vertical pipe must be insulated, and in order to avoid condensation, make insulation. Since chimney is a structure, on which the safety of the structure and the health of people directly depend, there should be no errors and omissions in the process of its installation. Before installing the chimney, it is necessary to study its device in detail.

  Chimney device in a bath: types of chimney structures for a wood-burning stove and features of their installation with video

  
  To remove the products of combustion of fuel, to ensure long-term preservation of heat in the bath and fire safety, a properly arranged chimney is required.

The device of the chimney in the bath for a wood-burning stove

It is difficult to overestimate the importance of the chimney system for comfortable, convenient and safe operation of the bath. Requirements for the performance of work on the device of the chimney:

• Compliance with fire safety rules. One of the most important requirements, as it is directly related to the safety of human lives. Executed by
  • careful isolation of the chimney from floor materials, usually combustible. In addition, during the design and construction, a significant thickness of the chimney is laid;
  • compliance with the minimum required distance between the chimney and the wall;
• Good traction. It is also achieved in two ways:
  • the length of the chimney (optimally - 5-6 meters) - the longer it is, the stronger the draft;
  • reducing resistance by maximizing the alignment of the walls of the chimney;
• High-quality materials that meet the operating conditions;
• Optimal temperature. The operating conditions of the chimney must correspond to those planned. For example, if the smoke temperature is insufficient at the inlet, condensate will form, which will subsequently lead to the destruction of the chimney structures from the inside.

Features of chimneys for wood stoves

The main feature of the use of wood-burning stoves in the bath is the greater, in comparison with other types of stoves, the heat from them. As a result, the requirements for chimneys must be increased.

thick wall pipe

The simplest chimney design is an installed thick-walled ferrous metal pipe with a wall thickness of 3 mm. and more. Installation takes place using welding. But such a semi-handicraft design is not reliable and fireproof.

Chimney supplied with the stove

In most cases, when purchasing a wood-burning stove, a chimney system is supplied that is ideal for this type of stove. You can install it both independently and with the involvement of third-party specialists. Moreover, the cost of such work is relatively small - it starts from 4-5 thousand rubles.

Structures can be made from a variety of materials, ranging from steel with a diameter of usually 9 to 20 mm. and ending with ceramic pipes. Moreover, it is the latter that are considered the safest and most durable. The following are chimneys made of stainless steel. The next in terms of quality are sandwich pipes. If we return to steel pipes, then the most preferred steel grade is AISI 310S, which has increased heat resistance.

The complete scheme of the "furnace - chimney" design and related systems is as follows.

Particular attention is paid to the passage through the roof or through the wall, depending on the type of chimney construction.

Types of construction of chimneys for wood stoves

The principle of the device is that the exhaust gas is discharged due to the natural draft created. The chimney pipe is led out through the wall and then rises vertically upwards. The minimum height required for normal operation is 5 meters.

Interior

The chimney pipe rises directly from the boiler, passing through the ceiling, upwards with a final exit to the roof. Typically, this type of chimney is made in two layers to increase the fire safety of the system. In addition, the presence of thermal insulation between the layers helps to avoid the occurrence of condensate inside the pipe.

Brick chimney

When constructing a chimney, refractory bricks should be used, laid on a mortar of special heat-resistant mixtures, or using a conventional clay-sand mortar, which is a more economical option that practically does not lose in quality of construction.

Brick chimney device

• The overhead pipe installed on the furnace. It is equipped with a valve to control the flow of smoke. Masonry is carried out with a mandatory special dressing of bricks.
• Fluff. It starts 5-6 rows of bricks before overlapping. The cross section of the chimney remains unchanged, and from the outside it becomes wider by 25-40 cm.
• Riser. Part of a brick chimney running through the attic.
• Otter. Expansion of the chimney after reaching the roof, preventing precipitation from entering the junction of the chimney and the roof.
• Neck. The dimensions are similar to the main chimney. An umbrella is placed on it.

The device of the chimney in the bath for a wood-burning stove - types of structures

In this article, we will consider the construction of a chimney in a bathhouse for a wood-burning stove, the requirements for performing work, and the types of chimney designs for wood-burning stoves.

A chimney for a sauna stove is a very important structural element of the entire bath. After all, it performs the function of removing carbon monoxide to the outside and prevents soot from settling on the walls of the room. And in order to choose the right design, you need to familiarize yourself with what types of chimneys are, what material is better to use and how to properly install such a design.

The task of the chimney is to prevent carbon monoxide from entering the bath. To do this, it is necessary to adhere to the requirements of building codes and fire safety rules.

What designs are best for a bath

First of all, the chimney for a sauna stove must withstand high thermal loads and have good draft. To date, the following types of chimneys for a bath are used:

• Brick;
• Sandwich chimney;
• Chimney made of steel pipes.

The materials of such structures have high heat resistance and thermal conductivity, and do not emit harmful substances. For the installation of a brick chimney, a special refractory brick is used, which can withstand high temperature loads. But the process of building a brick structure is a very difficult job.

It is necessary to correctly observe the entire laying technology, so this type is not installed so often.

It will be much easier to install a sandwich chimney, which consists of two stainless pipes, and a layer of mineral wool insulation is laid between them. The parts of the sandwich pipe are connected using elements such as:

• Knee;
• Tee;
• brackets;
• Pass pipe;
• Roof cutting.

For strong fixation, all elements are fixed with clamps and special sealed gaskets.

Sandwich pipe must be selected based on the parameters of the furnace.

A chimney made of steel pipes is mounted by welding, which connects the elements together. At the same time, welding seams must be performed at the highest level in order to prevent leakage.

The role of the heat exchanger for sauna stoves

The heat exchanger for the sauna stove performs a very important function, without which no bath can do. This is water heating. According to the method of placement, heat exchangers are:

• Mounted;
• Embedded.

The advantage of hinged structures is that the heat exchanger, which is located on the chimney pipe, uses the heat of the ejected hot gases. By contact with the hot surface of the chimney pipe, the heat exchanger heats the water, and then it goes through the pipes into the hanging tank. Due to the large volume of the chimney, the heat exchanger quickly heats the water and maintains the high temperature for a long time.

The heat exchanger, which is located inside the sauna stove, is different in that it consumes heat from heating the stove.

Whichever method of installation is used, a prerequisite for the correct operation of the system is to fill it with cold water before lighting the stove.

The heat exchanger is connected using two fittings, which are attached to the battery or a mounted tank from above and below. Further, the heat exchanger works due to the circulation of the liquid, which is heated or with the help of an electric pump.

To date, the heat exchanger is installed together with the following structures:

• With a brick sauna stove;
• With a metal oven.

The advantages of a metal furnace are:

• Rapid heating of the bath;
• Easy to install;
• Compactness;
• Aesthetics.

Thanks to all the above qualities, as well as having many varieties and modifications, metal furnaces are increasingly replacing brick installations from the building materials market every year.

Installation of a chimney for a bath

Installation of a chimney for a bath should be carried out strictly in accordance with the requirements of building codes. The chimney for a sauna stove performs a very important function - it removes flue gases to the outside, which are formed during the combustion of fuel. Therefore, it is extremely important to comply with fire safety rules when installing the structure.

Today the most popular is the sandwich chimney. But the sauna stove has very high combustion temperatures, therefore, to install the structure, it is necessary to select especially heat-resistant pipes. According to the installation method, chimneys for the furnace are divided into such types as:

• Internal;
• Outdoor.

The internal method is a classic design installation option. Its advantage is that the room is additionally heated. But this design is more laborious to install.

With an outdoor installation method, the chimney is led through the wall to the street. When the chimney passes through the wall, a prerequisite is high-quality insulation of the pipe. The disadvantage of such an installation is that the pipe will not be able to give off heat to the room and, accordingly, fuel consumption will increase.

Indoor and outdoor chimney

It is better to entrust the arrangement of a chimney for a sauna stove to an experienced craftsman, but it will not hurt the owner of a future building on a personal plot to understand the intricacies of such work.

The duration of the preservation of thermal energy in the room, the fire safety of the building, as well as the timely removal of fuel combustion products depend on the correct arrangement of one of the main elements of the bath.

Today, in specialized stores, you can get detailed advice on the purchase of a set of elements necessary for installing a chimney in a bath building. To do this, sales consultants have specially designed software.

Varieties of chimneys for sauna stoves are not limited to metal structures.

What are they like?

Types of furnace chimneys

Chimneys for baths are different:

• according to the material of manufacture;
• according to the design features and the place of installation.

For many years, sauna stove chimneys have traditionally been made from fired bricks. Now metal products have become increasingly popular.

According to the location and design solution, they are of two types:

• chimneys installed indoors and passing through the ceiling and roof;
• structures brought through the wall and climbing it outside the building (read: "").

Choose the best option, taking into account the advantages and disadvantages of each type of flue pipe.

Brick chimney structures

Previously, chimneys were laid out of bricks, since there was no alternative to this building material during the construction of this element of furnaces. The creation of brickwork is a laborious process. In this case, one cannot do without the use of a laying scheme and the obligatory observance of all design parameters.

Brick chimneys are durable and durable, which has been proven by time. A material such as brick has a structure capable of accumulating thermal energy and evenly dissipating it. A brick structure is much more fireproof than a prefabricated metal chimney produced according to the latest technologies.

A significant disadvantage of a chimney lined with bricks is their rough and angled inner surface. Soot collects on it, which over time begins to interfere with the passage of smoke and reduces traction, which negatively affects the degree of heating of the heating unit.

A brick pipe for a bath stove, heavily covered with soot deposits from the inside, can cause a bath to smoke or even catch fire during kindling from sparks that fall on it (read: ""). As a result, such a situation can lead to sad consequences.

Metal chimneys

Mounting a metal chimney is much easier than a brick building and its installation will cost much less. Sandwich structures currently in use are made with insulation. They are practical compared to single-walled metal products, but they lack the ability to retain heat inside the unit for a long time.

The main advantage of metal structures is the presence of a smooth inner surface, on which there are no edges. Thanks to this feature, the smoke will freely go outside under the influence of a turbulent flow.

Metal chimneys also have a disadvantage. When there is a sudden change in temperature, condensation may form on the inner surface. If such a design for a heater is planned to be installed in a region with long severe winters, then pipes with the thickest possible layer of heat insulator should be preferred.

External and internal smoke extraction system

When choosing a chimney, you should consider which type of installation will be used - internal or external. Each installation method has its advantages and disadvantages, and you also need to know about them before deciding which pipe to use for a sauna stove.

At one time, American architects came up with a method that allows you to take out the smoke exhaust structure on the outer surface of the building wall. This option for installing a chimney began to be used in domestic baths due to the simplicity of the device. The pipe connected to the furnace does not rise to the ceiling of the room, but is led out through the wall of the building.

The advantages of a chimney mounted in this way include increased safety and the fact that it is not required to make isolated transitions in the roof and attic. Laying the pipe out through the wall saves the building from the possible flow of precipitation through the cracks and gaps formed between the roof covering and the pipe.

But the external chimney has a significant drawback - it quickly cools down, which means that condensation forms inside it. To eliminate this problem, the pipe should be carefully insulated.

Another negative point inherent in chimney structures taken out to the outside is the inability to give off additional heat, despite the fact that fuel consumption increases.

There are also combined chimneys. In them, a metal pipe is removed from the device, after which it is taken outside to the street. Then it enters a brick-lined chimney built into the wall and rising to the required height.

The metal chimney structure located inside the bath is placed on top of the heater and raised to the ceiling, laid through the attic and the roof to the level of the ridge located on the roof.

Such chimneys have a great advantage, since all the heat energy received in the furnace, when moving through pipes made of stainless steel or steel, will simultaneously heat the attic and the rooms of the bath building. This means that indoor air takes longer to cool down, resulting in significant savings in fuel consumption.

Provided that the installation of the internal smoke exhaust structure is correctly carried out and the integrity of the joints of the elements is constantly monitored, the system is able to serve without repair for many years.

Such options have a drawback, which is the need to lay a pipe through the ceiling and roof.

Materials for the construction of chimneys

All necessary materials must be purchased after choosing a chimney design option.

To install a brick chimney, you should purchase a heat-resistant brick and a special composition designed for masonry, which is a dry mix. Some experienced stove builders prefer to work with a clay-based mortar. You will also need material to create a fungus above the pipe.

To mount a chimney for a stainless steel or steel sauna stove, first draw up a detailed design drawing with all pipe bends applied to it, and only then acquire the required details.

The places where the smoke exhaust system passes through the enclosing elements of the building should be reflected on the paper. At the turning points of the pipe indicate the approximate value of the bending angle. Based on the prepared scheme, sales consultants of a specialized store will always select all the necessary materials for installation work.

In addition, you will need two metal sheets with holes that are similar to the diameter of the pipe. They will be required for mounting on the ceiling of the bath and on the floor of the attic. A heat-resistant material is also needed for laying around the pipe in the attic. It will serve as protection for flammable elements located around the smoke exhaust structure.

To equip the waterproofing near the pipe on the roof of the building, you will need an adhesive-sealant and a special rubber seal that is placed on the chimney.

Pipe selection criteria

When buying these elements for a chimney system, be sure to consider the following:

1. The size of their internal section. Pipes for bath stoves made of stainless steel or steel are calculated taking into account the designed power of the unit. For bath buildings, the inner diameter is usually 15–20 centimeters. In the event that the cross section is too large, heat will not be able to linger in the furnace, and pipes of too small a parameter will not create the draft required to remove smoke. At the same time, in none of the sections of the structure, the diameter should be less than that of the outlet pipe of the heating unit.
2. The length of the chimney pipe cannot be less than 5 meters, and the more accurate value of this parameter depends on the installation location on the roof. If it is planned to bring it out in the middle of the slope, then the pipe must be raised above the level of the ridge by 50 centimeters. The best option for the location of the chimney on the roof is considered to be 1.5 meters from the ridge, but this value is not mandatory and largely depends on the location of the furnace in the room. The quality of traction is affected by the height of the pipe.
3. In order for the structure to serve for a long time, the thickness of the metal for the manufacture of pipes must be at least 1 millimeter.
4. Provided that it is planned to install a tank for heating water in the chimney system, this container will operate according to the “samovar” system - it is welded to the chimney pipe. See also: "".

Companies producing this type of pipe make them with a pre-installed hot water tank. It has 2 - 3 holes designed to connect the water supply elements in order to fill the tank and dilute the heated water at the points of its intake.

The device of internal metal chimneys

After the installation of the heater is completed, they begin to equip the chimney structure, performing work from the branch pipe of the sauna stove. This can be either the beginning of a metal chimney or a section of the smoke exhaust structure that connects the heating unit to a brick pipe.

Since there are two types of chimneys, their installation is different. When the pipe is placed inside the bath building, then almost the entire structure is located vertically. The installation of the individual elements is carried out in such a way that each part located above is placed on the one below. This method is called "smoke" editing.

When using the sandwich pipes shown in the photo, they are installed differently, using the "condensate" method. Its essence is that in order to equip the internal part of the system, the upper pipe is placed in the socket of the lower element. For the outer part of the structure, the "smoke" method is used.

Thanks to such a chimney device, the moisture accumulated in the pipe can freely flow down and enter the condensate collector without touching the heat-insulating material, which, in the event of an excess of moisture in it, loses its inherent properties.

The joints of the elements should be located so that the connection is not at the level of the roof, and also does not fall on the attic and interfloor floors. If the heating unit is planned to be mounted in close proximity to wooden walls, they must be protected from fire or overheating. For this, heat-resistant materials are used, such as asbestos boards, which are fixed in two layers.

When installing samovar-type hot water tanks, they must be located near the furnace compartment, directly above it or in the attic, if hot water needs to be distributed not to one room, but to two - a washing room and a shower room.

Before proceeding with the installation of pipes, their joints should be smeared with a heat-resistant sealant and, after completion of work, additionally fixed with special wide clamps.

When, when connecting the individual parts of the chimney, significant gaps remain between them, the part to be inserted is sealed. For this, an asbestos cord is used - a pipe is wrapped around it.

The first of the sections of the structure, attached to the branch pipe of the unit, cannot be made multilayer, it must be made of a single-walled metal pipe with special connections, in which there is a valve. This chimney adjustment element (damper) is used to create and maintain the required level of draft for a while while the bath is warming up. After completion of the furnace, the valve allows the heating unit to store thermal energy for a long time.

To make it easier to lay the pipe through the ceiling, it is advisable to use a box. The height of its walls should exceed the thickness of the barrier by 30–40 centimeters. A distance of at least 18–20 centimeters is left between the walls of the box and the pipe.

The order of installation of this element is as follows:

1. A square-shaped hole is cut out in the ceiling so that a box enters it, the lower part of which is fixed to the ceiling.
2. Through a hole made in the bottom, the chimney is taken out to the attic.
3. Then the box is completely filled to the very top with heat-resistant material having a small weight, for example, mineral wool or expanded clay of the middle fraction. The insulation must be laid as tightly as possible.
4. In the attic, the box is covered with a metal lid equipped with a round hole. It is placed on the protruding part of the pipe.

As a rule, the elements of the chimney are placed vertically in the attic, but sometimes they can get on the bars of the crate. In this case, a slight bend is made in the structure using bends.

After the roofing material is laid, waterproofing measures are carried out, since moisture can sometimes get into the gaps between the coating of the building and the pipe. An elastic element is put on the pipe. It is fixed to the roof surface with a moisture-resistant sealant, and then securely fixed using roof fasteners. A protective umbrella is installed on top of the pipe - it will not allow various debris, dry leaves, branches, dust and precipitation to enter the structure.

Installation of external metal structures of the chimney

If the chimney installation scheme provides for its external placement, the pipe coming from the heating unit is laid through the wall of the building. To ensure the safety of the operation process, experts advise laying out brickwork, which will insulate the wall when the chimney is led through it.

To turn the pipe in the direction of the wall, you will need a product such as a bend or elbow. These structural elements have bends at an angle of 45 or 90 degrees. They are selected taking into account the installation scheme of the smoke exhaust system.

The pipe to the stove in the bath can be brought out through the wall, both through the box and through the attic floor. The box is then filled with stone wool. Since there may be small gaps around the pipe, they are treated with a heat-resistant sealant.

A tee is installed on the outside of the building. Further from it, the installation of structural elements will be carried out: up, along the wall and to the condensate collection point located below.

For vertical fixation of the chimney, holders are used. To ensure good traction, the pipe should rise about 50 centimeters above the height of the ridge. A protective fungus is placed on top of the head.

Brick chimneys

A chimney lined with bricks can be root or mounted. For stoves installed in bath buildings, the first option is more suitable, which is placed next to the heating unit.

If the stove is built of bricks, then a chimney is attached to it. When the unit is made of metal, it is connected to a brick smoke exhaust system through a metal pipe.

Approximately a brick chimney diagram consists of the following elements:

1. Smoke damper, which regulates the internal draft of the heater. It is arranged in close proximity to the ceiling. The intensity of fuel combustion and the time the furnace is in a hot state depend on the valve.
2. Fluff (cutting). Designed for laying pipes through the attic floor. So it is customary to call the thickening of the walls of the chimney, provided that the value of its internal section is maintained. This structural element is needed to protect the materials for the manufacture of the ceiling from overheating and subsequent ignition.
3. Riser- a straight piece of pipe. It is located above the fluff and runs through the attic.
4. Otter. It is laid out in the place where the chimney exits through the roof. Its purpose is to protect the truss system from possible overheating. In addition, due to the bricks protruding from the structure, the otter covers the gaps between the roofing material and the chimney masonry.
5. Neck- this is the place where the pipe narrows to the initial external parameters.
6. headroom. It is located above the neck. When arranging it, the bricks are laid out so that they protrude outside the walls of the chimney. As a result, the headband provides additional protection from atmospheric precipitation.
7. Metal cap. Installed at the very top of the chimney. Does not allow dust, dirt, water to penetrate into the system.

Construction of masonry chimney structures

The chimney should turn out to be smooth, without protrusions and openings, with the exception of a hole designed for walling in a stainless steel or steel pipe.

It is laid out of bricks in the form of a pillar with an internal section in the form of a well, the size of which may depend on the power of the unit:

• "in half a brick" - 130x130 millimeters;
• "in a brick" - 130x260 millimeters.

The basis for the smoke exhaust system is the foundation. It is laid out of the same thickness as for the oven and forms a common structure with it. The pipe is lifted to a certain row and the valve is mounted. Then they continue to do work according to a scheme suitable for both types of chimney. The number of bricks laid on each side of the structure may vary according to the size of the structure.

The sequence of actions when laying according to the order:

1st row - is the last row of pipe neck arrangement.

2nd row. They start laying out the fluff - the bricks are placed with a shift outward by approximately a third of the length of the brick. In the process of work, it will be necessary to use not only whole products, but also their fragments. To do this, they are broken into the necessary parts with a small pick.

When the bricks are shifted to the side, they should be supplemented with fragments from the inside of the structure, since the inner diameter of the well should remain unchanged during the laying. If this rule is not followed, the traction force can be significantly reduced.

From the 3rd to the 5th row. They continue to lay out the fluff, shifting the bricks by a third of their length and maintaining the value of the internal section.

6th row. Its size is similar to the fifth, but it fits without shifting.

7th and 8th rows. The laying order is similar to the first row.

After completing the creation of the cutting, they begin to build the otter, but this work is difficult, because with the help of each subsequent row, the result should be a step with bricks protruding by a third:

1. Its first row in size and shape is made similar to the last row of fluff.
2. Starting from the second row, they begin to lay out the steps, which will expand the structure by one third of the width of the brick to the outside.
3. All subsequent rows are laid according to the scheme for creating an otter.

Then follows the neck, and after it - the head, consisting of two rows, while the bottom row is made protruding outward. At the final stage put the cap.

As a result, the combustible elements present in the attic floor will be protected by fluff, but it is still necessary to create waterproofing of the pipe, and before the roof is covered with roofing material. Do waterproofing work using mastic and roofing material. It is necessary to apply the mastic on the surface of the lower part of the pipe, and then heat it up with a burner. Next, roofing material is glued onto the hot composition.

Then, a roofing material is mounted on top of the waterproofing close to the pipe, and a decorative finish, called the "apron", is already applied to it. All remaining gaps are filled as densely as possible with sealant so that moisture does not penetrate into the gaps between the brick pipe and the roof.

Despite the fact that it is better to entrust the creation of a chimney to professionals, you can build it yourself. The most difficult task is the installation of pipe laying units through walls and ceilings. You should first study the information available on this topic.

Experts warn: the chimney is a structure, the quality of the device of which depends not only on health, but also on the lives of people, not to mention the integrity of the bath building and the safety of property.

Particular attention should be paid to the fire safety of the structure, since during active combustion the temperature in the chimney of the sauna stove can reach 500-700 degrees. During the construction process, no simplifications in work should be allowed - this can cost a human life.

If you have the slightest doubt about your own capabilities, it is better to order the arrangement of the chimney from specialists.

Theoretically, the combustion of any fuel is accompanied by the release of carbon dioxide and water, but in practice this is far from being the case. From insufficient combustion of fuel, even if it is ideal, the process is accompanied by the formation of soot and carbon monoxide. In addition, the combustion materials themselves are far from ideal and contain a large amount of impurities that will be added to the indoor air in the form of combustion products.

All this together will give not only pollution of the bathhouse and stench, but also a threat to human life, since carbon monoxide is poisonous. Poisoning them can have severe results and can even lead to death. Therefore, the real way out of the situation is the chimney. This is a fairly simple and useful device that provides natural removal of combustion products and oxygen access to the combustion zone. In this article we will consider the main types of chimneys such as steel, ceramic, glass, sandwich. And also we will talk about how to make a chimney in the bath with your own hands with step-by-step instructions and a video. And so, where to start?

Choosing a chimney for a bath: criteria

Choosing a chimney for a bath is a pretty serious undertaking. We can say with some confidence that choosing a stove is much easier. The furnace equipment market is represented by a wide range of products, so choosing a furnace will not present any particular difficulty. The flue is a separate component, the complete system to which increased requirements are imposed.

If the arrangement of the chimney is taken without due responsibility, then in the smoke channel there may be a lack of rarefaction or, as the people say, reverse draft. Which will prevent the removal of combustion products as a result, smoke will occur, which, in turn, can cause fire and fire. Therefore, the safety of your building, and the efficient operation of furnace equipment, directly depends on how competently the chimney is made and installed. At the present time, chimneys are made of concrete, ceramic, steel, brick and even glass.

The chimney must be strong and durable. Be resistant to the influence of high temperature regimes during fuel combustion, remove smoke at low temperatures, counteract the influence of condensation products, and also comply with fire safety regulations. Now it is worth thinking about the option of the chimney channel. Will it meet the requirements of the manufacturer of the already selected furnace unit?

Thanks to the development of science and technology, a significant number of chimney channels have been developed, but a brick chimney has been and remains a classic of the genre. This option has long been tested by time and is still used today. But he was replaced by alternative devices from new materials that were not previously used in the manufacture of chimneys. For example, sandwiches, ceramic and glass chimneys. Now, before deciding on the choice of material for the chimney of the future bath, it is necessary to study the technical and operational indicators of the equipment that you decide to install. After all, when installing it, you need to take into account the internal section of the chimney, its length and height. And what material to use for the smoke channel is another choice.

Material for the chimney in the bath

brick chimney

As already mentioned, brick used to be the main material in the manufacture of chimneys. The advantage of building a brick smoke channel has always been the cheapness of the material. Construction was the most economical and low-cost. Sand and clay, water and bricks were always within reach. Unfortunately, at this time, the search for a specialist in furnace affairs is fraught with certain difficulties. And in a brick chimney, high-quality operation directly depends on the professionalism of the stove-maker. Therefore, the price of the services of a qualified specialist has increased significantly. The rectangular section contributes to the creation of local turbulence in the smoke channel and leads to its clogging. You need to clean it at least once every six months. However, if a brick chimney is folded correctly, then this is a guarantee that it will last for many years. But not always a brick chimney is suitable for installation in a bath. First of all, from the financial costs of its installation.

steel chimney

The time of using brick as the only material for smoke channels has passed. Metal was the alternative. The use of heat-resistant stainless steel in the arrangement of smoke channels for a bath has become a breakthrough in chimney technology. Two-pipe designs have gained wide popularity. They are two pipes of different diameters with a non-combustible insulation between them. The insulation keeps the chimney from excessive condensation and its effect on the pipe. Such structures are called sandwich. As a rule, the outer pipe is made of either stainless steel or galvanized steel. Galvanized steel is more of a budget option that does not affect performance. The inner tube is made only from heat-resistant stainless steel with a thickness of 1 mm or more. When choosing a pipe, pay special attention to this parameter. Heat insulator based on basalt rocks that can withstand high temperatures. Such flue channels are cylindrical in shape, which means they are less susceptible to contamination.

Sauna ceramic chimney

A new material that has recently appeared on the market for furnace equipment is ceramic fireclay pipes. They have absorbed all the advantages of steel structures. At the same time, they are characterized by the reliability and long service life of brick smoke channels. In their composition, they have an internal fireclay pipe, a heat-insulating layer of basalt rocks and an outer casing made of stainless steel or lightweight foam concrete. The price of such a pipe is much higher than a steel chimney, but due to the long service life, the cost is more than paid off. This material competes with brick structures in terms of reliability, durability and fire safety. In principle, this is the same pipe, it is as easy to assemble it as steel sandwiches. Although in some cases, the performance under it requires strengthening the foundation. There are special elements for collecting pipes into a finished structure. When purchasing a set of flue pipes made of ceramic pipes for your particular case, all these elements and materials are included in the delivery. The cost of ceramic chimneys is about an order of magnitude higher than steel sandwiches.

glass chimney

The ideal option for chimney systems is a smoke channel made of glass. This material has enormous advantages: absolute absence of corrosion, moisture resistance, low thermal inertness. But the cost of such chimneys is very high, and if we add the huge installation costs, then such material simply has not found distribution because of the huge price. Although some optimists argue that glass chimneys are behind it, the future will come when all smoke ducts will be made of glass.

Separately, I would like to dwell on chimneys made of asbestos pipes. This is a material that cannot be used for the construction of chimneys. It is carcinogenic and flammable. An asbestos-cement smoke channel can cause a fire in your bath.

Summarizing the above, we can conclude:

· Brick chimney, labor-intensive installation, requiring a certain qualification of performers.

· Steel smoke channel from pipes - not expensive, but short service life.

· A chimney made of ceramic pipes is durable, but the cost is much higher than that of steel chimney structures.

· The glass chimney has practically no drawbacks, but the price of the material and the cost of installation are expensive. Not received distribution.

· It is impossible to build chimneys from asbestos cement.

The design of the chimney in the bath

By location, smoke channels for baths can be divided into the following:

internal, the chimney passes through the interior of the building;

external, the chimney channel from the furnace equipment is directed outside the room and passes through the open space.

The advantage of the internal location of the smoke exhaust is the use of the temperature of the combustion waste to heat the sauna room. This design facilitates the creation of draft in the chimney channel.

The external device of the chimney facilitates the installation of the structure, but requires additional fuel costs, since the heat of the smoke heats the outdoor space, and not the bathhouse. In addition, the issue of the formation of condensate and soot in the chimney is acute. To avoid these problems, it must be additionally insulated.

Structural elements of the chimney system

The ideal arrangement of the chimney channel in the bath is a straight structure, passing from the stove strictly vertically upwards. Such a chimney is built of brick. A feature of such a furnace is the location. As a rule, it is installed in the middle of the bath structure, taking into account the location of the beams and rafters.

The advantage of steel and ceramic chimneys is the presence of additional elements. They allow the placement of the stove almost anywhere in the room, and in the presence of obstacles, they make it possible to design a chimney channel with a bend or a horizontal part in order to bypass the encountered obstacles.

But at the same time, it must be taken into account that the total distance of a horizontal or inclined section should be no more than 1 meter. If this size is exceeded, this will adversely affect the operation of the chimney channel. In a horizontal section, products of incomplete combustion of fuel will collect, and the movement of smoke will be difficult. The maximum number of turns is allowed no more than two.

The connection of horizontal and inclined sections is ensured by the presence of various shaped parts of the chimneys. When installing them, it is necessary to initially resolve the issue of further cleaning the chimney. The knee is where soot accumulates. Here, an element such as a tee is considered an output. The presence of a removable glass in it allows you to clean the chimney easily and without problems.

The tightness of the pipe joints provides not only good traction, but also prevents smoke from entering the sauna room. For safe and fireproof passage of a wooden ceiling and roof by a chimney, special nozzles are used. A pipe is inserted at the intersections.

Wall brackets are used to fasten a steel pipe that is not light in weight. Installation of fasteners is carried out at a distance of no more than two meters from each other. In the place where the chimney exits to the roof, a roof cut must be made, which will prevent precipitation from entering the bath.

The ingress of rain and snow into the smoke channel is excluded by installing a protective fungus.

Chimney design and installation

Carrying out the project and installation of the chimney yourself, you must:

1. Competently approach the choice of the cross section of the smoke channel pipe. The small size will not allow to fully remove the combustion products of the fuel. A wide cross section will ensure the rapid passage of smoke, which does not allow warming up the bathhouse. This will increase the time and amount of fuel for heating. The size of the pipe section depends on the power of the furnace. Its indicator is in the range from 140 to 270 mm.

2. The optimal shape of the chimney is round. Through such a channel, smoke passes easily. It is less clogged and easier to clean.

3. If you place the chimney closer to the inner wall of the bath, this will improve thermal insulation.

4. The height of the chimney channel is indicated in the passport of the furnace equipment. But if there are no specific dimensions in the instructions, and you do the installation of the structure yourself, then you should install a chimney of at least 4.5 m.

5. The height distance from the roof ridge to the chimney head must be at least half a meter.

6. The smoke channel is equipped with a damper for draft adjustment.

7. As an additional protection for the walls and ceiling in the chimney area, it is recommended to use basalt wool, copper sheet or other non-combustible materials.

8. To increase fire protection and prevent fire at the place where the chimney passes through the ceiling, it is necessary to increase its thickness with non-combustible materials by at least 5 cm.

How to make a chimney in a bay with your own hands: step by step instructions

Chimney installation can be divided into several stages.

Stage number 1. Preparatory.

Before you start installing the chimney in the bath with your own hands, it is necessary to protect the places where the smoke channel passes through the floors. This section will require the use of a special element called a through pipe.

Stage 1. We start with the preparation of the pipe. We place a layer of basalt wool along its outer surface.

Stage 2. Then we proceed to the insulation of the inner surface. We designate the installation point on the ceiling and prepare a rectangular hole for the future smoke channel according to standard sizes.

Stage 3. In places where the pipe contacts the ceiling, we install an additional insulating layer, then we mount the pipe.

Stage 4. Between it and the smoke channel, it is necessary to leave a minimum gap for additional heat removal.

Stage number 2. Roof work

Now we start cutting the roof.

Stage 5. We take dimensions from the outside and inside, not forgetting to take into account the slope of the roof.

Stage 6. From the inside in the roof we cut out the necessary hole for the chimney.

Stage 7. We take galvanization, with a hole made in advance for the smoke channel, and fasten it to the roof.

Stage number 3. Installation work.

We propose to consider the installation operations using the example of assembling the most popular two-circuit system.

Important point! The assembly of the chimney is carried out only from the bottom up.

Stage 8. We start connecting the chimney from the stove. We dock the sandwich module with a special oven outlet. We do not isolate the area near the heater, because the temperature in this place is too high. Regardless of the quality of the chimney material, due to the maximum temperature conditions, this section will fail in a short time.

Stage 9. Each subsequent internal module is inserted inside the previous one. Then put on the outer tube. In this case, it is necessary to ensure that the new module is docked with the previous narrow end. This will ensure that the condensate formed during operation will freely flow down the pipe, and will not flow into the joints.

Stage 10. After mounting all structural elements, we fasten the tees with prepared fasteners and seal all connections with clamps.

Stage 11. At the end of the work, we remove the protective coating and apply a refractory sealant that retains its properties at high temperatures. And so, you built a chimney in your bath completely with your own hands!

Chimney cleaning

Bath built, chimney installed. You enjoy the pleasures of the bath ceremony. Like any device, the smoke channel requires maintenance. In our case, this is its cleaning. Over time, a layer of soot forms on the walls of the chimney, which impairs draft and can cause a fire, which, in turn, can lead to a fire.

The most common and effective method is mechanical cleaning. For its implementation, you will need special rods, preferably collapsible with ruffs, weights, and sometimes even a sledgehammer. This procedure is quite laborious, and most importantly, dirty. Therefore, before cleaning the smoke channel, it is necessary to remove all things from the bathhouse, and cover the walls, ceilings and floors with plastic wrap.

Another way to clean the chimney is to burn off the soot. To do this, it is necessary to heat the stove with wood that creates good traction and strong heat, for example, aspen. This will cause the soot to burn out and be carried as ash through the chimney.

Recently, chemical preparations for cleaning chimneys are gaining popularity. But they are no longer a means of cleaning, but a preventive measure, to increase the time period between cleanings.

Mistakes in the construction of the chimney

It is worth paying attention to a number of mistakes that are made during the construction of chimneys by non-professionals:

• Use of unsuitable materials such as asbestos and aluminium. This may cause a fire.
• Unauthorized change in the diameter of the chimney can reduce the efficiency or destroy the structure of the bath.
• Combining several chimney systems into one.

A few more typical chimney construction errors are shown in the video below.

Sometimes it seems that you can build a chimney in a bathhouse with your own hands quickly, without anyone's advice. But the construction of a chimney is a rather responsible procedure that requires compliance with the rules, the availability of skills and the study of modern techniques. This will save you from mistakes, and the chimney you built in the bath will last reliably and for a long time.

We also recommend you:

No sauna stove can do without the right equipment of all its parts and departments. The device of the chimney in the bath is somewhat different from the chimney system of the heating stove for the house. Therefore, in order to achieve the greatest efficiency of the functions of the sauna stove, it is very important to take into account all the nuances of building not only the firebox and heater, but also the chimney.

The device of the chimney in the bath for a wood-burning stove

It should be noted right away that the arrangement of this main bath facility is better done by an experienced master, but if you want to try your hand, you need to carefully understand all the subtleties. Not only how quickly and well the bath room warms up, but also its fire safety depends on a properly arranged chimney.

Basically, in the construction of a sauna stove, two types of chimney are used - these are indigenous and mounted.

• The root chimneys are built separately, next to the stove, and connected to it with a special pipe, which removes smoke into the main channel. This kind can even be used for two or three ovens. Naturally, in this case, it must have an appropriate inner diameter, and pipes from different heaters are mounted at different heights.

• The chimney systems with a built-in pipe differ from the indigenous ones in that they are installed directly on the furnace pipe and are brought out into the street through a wall or roof. In bath buildings, the owners often prefer mounted chimneys.

Also, chimneys can be divided into external and internal.

• The first ones are brought out through the wall, and their main part passes along the street, where it is fixed to the wall surface with the help of brackets. But it must be said right away that the external view of the chimney is not suitable for a bath, as it cools faster, no matter how well it is insulated. Namely, for a bath, losing excess heat is an unforgivable luxury.

• Internal chimney systems are installed more often, so it’s worth learning more about them.

Chimney passing indoors through the ceiling

One of the main advantages of an outdoor morning chimney is its maximum verticality, which contributes to good draft. However, it certainly has its drawbacks:

- for its device in the finished building, you need to cut (punch) holes in the ceiling and roof, as well as make reliable waterproofing. In addition, you will have to work hard to isolate the passage in the ceiling with heat-resistant material;

- a chimney passing outside is much easier to repair than an internal one.

But despite the possible disadvantages, the heat given off to the room is much more important for the bath, so it’s better not to be lazy and spend it inside so as not to lose the bath heat and not burn excess fuel.

Materials and features of the manufacture of a chimney for a wood-burning stove

The choice of material for the chimney will depend on which stove is installed in the bath.

• A brick oven can be equipped with a chimney, also made of brick, metal or made of asbestos cement.
• The metal version of the stove with an equipped heater is usually supplemented with the same chimney (less often - from asbestos cement). But most often this — metal pipes with a layer of insulation, the so-called sandwich chimneys.

• Asbestos concrete the option of chimneys, especially for bath stoves, is undesirable for the most important reason - this is the porosity of the material. Due to the structural features of asbestos cement, the condensate remains on the channel walls for a long time or even soaks into them, which leads to the destruction of the material. Such a pipe can burst or, if burnt out, even explode. To reduce the formation of condensate, the asbestos-cement pipe is dressed in thermal insulation and lined with brickwork.

Whatever material the chimney pipe is made of, its parts must be hermetically connected to each other, and the brickwork must not have gaps. These flaws make it possible for cold air to get inside, which not only reduces traction, but also contributes to the formation of condensate.

The diameter of the pipe must also be calculated correctly - if it is larger than necessary, the smoke rising through it will cool quickly, which also contributes to the formation of condensate.

It is worth paying special attention to the choice of the thickness of the chimney pipe of the bath. The inner version of the chimney must have walls of at least 12 cm, and the outer one - 38-40 cm thick. This will also protect against rapid cooling, which means moisture condensation.

The most important factor for this section of the furnace is the ideal smoothness of the inner walls of the pipe. It will provide the necessary traction, which means that soot will not be deposited on the walls in large quantities. Porous surfaces are capable of accumulating a large amount of burning, from which the chimney will have to be cleaned quite often. If a brick chimney pipe is built, then in the attic it is rubbed with clay mortar and whitewashed. Thanks to such precautions, in the event of cracks in the masonry or other defects, they can be immediately detected, as black smoke will seep through the cracks in the grout, and it will be clearly visible on the whitewash. This is a visual signal of the need for urgent repairs.

Sometimes a combined chimney design is used for bath stoves. In this case, its lower part is built of brick, and the upper part, passing through the floors and roof, is made of a modern sandwich pipe.

This option allows you to arrange neat small passages, which will be easier to arrange with heat-resistant material.

Chimney Safety

It is imperative to ensure high fire safety of the chimney for the bath. To do this, as mentioned above, pay special attention to the tightness of the joints of individual parts of the pipe, as well as to the cutting when the chimney passes through the floors and roof.

In places where the pipe will pass through the ceiling, it is necessary to isolate it from the wooden elements with heat-resistant material - this can be asbestos, mineral wool, sand or expanded clay.

• To do this on the ceiling in place chimney passage a metal panel is fixed with a hole through which the pipe will be passed.
• From the side of the attic, a kind of box is arranged, which should be 10-15 centimeters higher than the attic floor. Insulating material is laid or poured into it, which will protect the wooden floor from the high temperatures of the chimney. The pipe must be at least 25 centimeters from combustible floor materials.

• It is very important to arrange thermally insulating protection not only in the ceiling ceiling, but also on the wooden wall of the bath. Basically, bath buildings are built from pine, and its wood is quite resinous and can easily overheat and even burn out from the high temperatures of the nearby chimney. Therefore, the wall must be secured with a non-combustible material - it can be a special drywall, asbestos, masonry, foil mineral wool, or a combination.

• After passing through the attic, the chimney channel is led through the roof and rises above it by at least one and a half meters.
• Around the chimney, when passing through the roofing, waterproofing is arranged, which will keep the roof crate from moisture, and hence from the appearance of mold and destruction.

• A special protective fungus is put on top of the pipe head and a spark arrestor is arranged.

water tank

In the chimney system of the bath, erected from metal sandwich tube, sometimes a metal tank is built in for heating water, inside which passes bare part chimney. Tanks can have a different volume - this is first of all, will depend on the power of the selected furnace.

When choosing this chimney accessory, it is best to pay attention to a stainless steel product that will last a long time. Naturally, you need to focus on the diameter of the chimney pipe on which the tank will be fixed. It is better to purchase the whole set in a kit so that you do not have to disassemble an already assembled structure.

Branch pipes are provided on the water tank, on which sections of chimney pipes are put on. They must fit tightly with each other, otherwise the thrust will decrease, and carbon monoxide may enter the room.

A metal water tank is also built into the design of a brick chimney. In this case, the hot air from the furnace, passing next to it, heats the water poured into the tank. When building a container, you need to provide a place in the wall of the chimney where there will be a tap and a pipe with a tap to fill the tank.

Scheme of the device of the bath chimney

In this diagram, all the above sections of the chimney system of the sauna stove are clearly visible.

It is worth noting that the sauna stove with its firebox usually goes into another room - dressing room. This is provided so that there is no risk of getting burned during washing, and so that the attendant has the opportunity to put firewood in the firebox all the time.

Directly in the bath room, the stove itself is located with a metal crate, which encloses the red-hot walls and is 10-15 centimeters away from them. Pebble stones are laid in this distance, which, when heated, give off heat to the room, and if you want to get steam, they splash plain water or an infusion of fragrant herbs on them. The chimney and the tank arranged on it in this embodiment are also located in the bathhouse.

The figure also shows how the chimney should pass through the floors and roofs and how to ensure the complete safety of its operation.

Based on this scheme, you can easily arrange a chimney yourself if you strictly follow all the norms, rules, sizes and volumes of insulating materials.

All work - both on the construction of the furnace and on the arrangement of its chimney system - must be carried out with all responsibility and accuracy. It must be remembered that not only the safety of the bath itself, but also the life of the people using it will depend on the approach to this issue.
