Brief comparison of domestic and foreign boilers

When comparing products various manufacturers boilers in terms of functionality, fault tolerance and service level, it becomes clear that the products domestic manufacturers is not different special quality. The products of German and Swedish companies have the best quality, followed by boilers of Italian, Czech and Slovak companies, and then - products of Russian, Ukrainian and Belarusian manufacturers.

However, often people choose the products of the last three countries. Why? Because gas boilers manufactured by domestic companies, although not as convenient and without the proper level of service and maintenance, as those produced in European countries, they are still reliable so as not to cause a fire or explosion, they have acceptable prices for a domestic buyer. To put it simply, domestic companies produce high-quality gas heating boilers that work out their value.

The shop windows display gas-fired heating boilers produced by various domestic companies. Here are some of them:

• Zhukovsky engineering plant;
• Rostovgazapprat;
• BMZ-Vikma;
• Conord;
• Red boilermaker;
• Energy spare part;
• ROSS;
• Thermalwest.

Let's take a look at some of the manufacturers.

Floor standing gas boiler

Zhukovsky Machine-Building Plant - time-tested quality

It has been producing gas boilers since 1967, when the plant produced the first boiler of the AGV-120 series. Now the company is one of the leaders in the Russian market for the production of gas boilers for domestic needs, it is well known in the CIS. It produces reliable products with full autonomy and independence from electricity. Products are intended for use in heating systems for rooms with an area of ​​​​not more than 610 square meters and with a power of 11.6 to 68 kW.

Produced floor double-circuit gas heating boilers are divided into three classes: economy, station wagon and comfort. The difference between the classes is the level of the automation unit used. Economy class products use automation own production ZHMZ, station wagon class - Euro SIT, and comfort class - Mertik Maxitrol.

To avoid product defects, the production of boiler heat exchangers takes place on an automatic line from seamless pipes. The design includes additional plates to adjust the direction of hot flows. Taking heat from them, the plates transfer it further to the heating system. Thanks to this approach, it was possible to achieve an efficiency of 89% and at the same time reduce the impact of boilers on the environment.

The design of double-circuit boilers manufactured by ZHMZ is based on the transition from natural gas to liquefied gas due to a simple change of nozzles.

A nice bonus from the manufacturer is the instruction manual, which is attached even to economy class models.

Rostovgazapparat is the leader of the domestic market

Rostovgazoapparat JSC is a major domestic manufacturer that owns the majority of the Russian gas boiler market. In the late 1950s, the plant was the first enterprise in Russia to produce gas boilers, putting on stream the famous AOGV-80 series. The products of this manufacturer have high indicators of reliability and durability, and at the same time affordable price. The company is constantly striving to introduce new technologies in products and production. Products are intended for heating residential premises, power from 11 to 35 kW.

The company produces double-circuit gas boilers under three trademarks: Siberia, RGA and AOGV. Unlike ZhMZ products, the difference between the products of these brands lies in the quality of the automation unit used and in the power of the equipment itself. Boilers manufactured under the Siberia brand use Italian Euro SIT automation and power ranges from 11 to 35 kW, products manufactured under the RGA brand are also equipped with Italian Euro SIT automation, but the power range is smaller - from 11 to 17.4 kW, and AOGV boilers are produced with self-developed automation and power range from 11.6 to 35 kW.

When operating boilers manufactured by ZhMZ, it is allowed to use liquefied gas, but only on condition that the power does not exceed 18 kW. Boilers manufactured by Rostovgazapparat are non-volatile, with the exception of the Siberia Space model.

Factory Conord - good quality at a nice price

The Conord plant is another of the domestic manufacturers of double-circuit gas boilers and the leaders of the Russian market in terms of production. The first boiler was produced in 1979, and already in 2007 the number of produced boilers exceeded 1 million copies. The key feature of the boilers of this plant is the quality comparable to foreign analogues, but at the same time for significantly less money. To improve the quality of its products, the company regularly introduces new high-precision technologies into production. The products are used for space heating from 30 to 300 square meters, power from 8 to 50 kW.

On gas boilers of the Conord brand, three types of automation are used: domestic AGU-T-M, Italian Euro SIT and American Honeywell.

Gas boilers are equipped with either steel or cast iron heat exchangers. The power range of boilers with steel heat exchangers is higher than that of boilers with cast iron ones. So the power of the first is from 8 to 31 kW, and for the second - from 16 to 33 kW.

The manufacturer positions the boilers as non-volatile, due to the piezo ignition and the igniter, which is constantly on.

Conord products are equipped with atmospheric burners, there is no pressurization. The manufacturer guarantees that his boilers work, even if the pressure in the line is half the nominal one.

If it is necessary to ensure the full operation of the second circuit to produce hot water, it is better to choose a boiler with a power of 20 to 25 kW. A gas boiler of this capacity will supply from 10 to 12 liters of hot water per minute.

ROSS - the road to young people is everywhere

The ROSS company is a modern developing enterprise from Kharkov. The company was founded in 1991. Relative youth since its foundation does not prevent it from taking a strong position in the Ukrainian and Russian markets. Like at the Conord plant, ROSS staked on quality comparable with foreign analogues at a low price. The products are used for space heating from 70 to 960 square meters, power from 7 to 96 kW.

The company produces floor double-circuit gas boilers of three classes: Premium, Lux and AOGV. The products of three classes use the Italian Euro SIT automation, and the products of the "Lux" class also use the Italian NOVA automation. The differences between the classes are in the heat exchanger and the rated power. So, on boilers of the AOGV class, copper heat exchangers of the Italian company Giannoni are used, and the power of the boilers varies from 18 to 24 kW. Lux boilers use a rectangular steel heat exchanger of our own production, and the power range is from 7 to 96 kW. In boilers of the Premium class there is a cylindrical heat exchanger made of boiler steel, and the power is from 8 to 21 kW.

It should be noted that due to the cylindrical shape of the heat exchanger and the use of seamless fire tubes, it became possible to reduce the number of welds in the heat exchanger and eliminate the possibility of leakage inside it.

ROSS products

When working with gas boilers of this manufacturer, bottled gas is allowed.

Premium and AOGV class units are non-volatile. What can not be said about the boilers of the "Lux" class. Among them there are non-volatile boilers and those that need mains power.

Teplowest - innovation available to the consumer

Another major Ukrainian manufacturer of double-circuit gas boilers is Teplowest. It strives to introduce modern technical solutions while maintaining acceptable prices for domestic buyers. The power of the boilers is from 18 to 30 kW.

Heat generators use Italian Euro SIT automation and, depending on the series, are equipped with one or two heat exchangers. In the Optima series - one, in the Optima + - two.

The difference between Teplowest products and products from other manufacturers is the choice of method for removing gas waste. The range includes equipment with an open combustion chamber (removal of gas waste due to traction) and with a closed combustion chamber (using a fan or a coaxial system).

As a conclusion

When choosing the required unit for the heating system, they are determined with the brand of the manufacturer and with the method of installation on site. So according to the installation method, boilers are divided among themselves into wall and floor. What is the difference between them and how to choose the right one? Find the answers in the following video:

So, as already mentioned at the beginning of the review, not all domestic manufacturers of double-circuit gas boilers are represented here, but only those manufacturers whose products are in demand in the domestic market are considered.

Generalized about domestic double-circuit boilers: the low level of convenience of working with them in comparison with foreign counterparts is more than compensated by the level of cost. Therefore, you should not be distrustful of boilers manufactured in the territory of the Russian Federation or Ukraine. It is possible to find among the products of domestic manufacturers the boiler that will serve faithfully for many years.

In contact with

When choosing a boiler for heating, there are a number of points that you should pay attention to, especially since there are many companies on the manufacturer's market that offer such a product. Russian-made wall-mounted gas boilers do not differ in their characteristics from foreign ones, but at the same time they are much cheaper.

When choosing such a product, it is worth considering such points as further installation methods, power, room dimensions and a number of other points that you may need, especially since now there are a number of products that can work not only as heating boilers, but also as a device for water heating.

Characteristics of devices for fuel materials

According to heating materials, boilers can be:

• Solid fuel.
• Gas.
• Electrical.

Solid fuel boilers are mainly used for large rooms and larger private houses, for example, for small apartment such a device cannot be used. Solid fuel boilers mainly need separate rooms in which it can accommodate and work without harming the inhabitants of the house.

Gas boilers can be the most different sizes and have a number of additional features. Such a boiler for heating can be placed in a small bedside table even in the smallest apartment. The gas boiler can be for one circuit or two. So the device for one circuit will be used only for space heating, the device for two circuits can not only heat the room, but also serve as a means for heating water.

Electric boilers according to the type of gas, they can work on one circuit or on two. But you need to pay attention to the amount of costs. The good thing about using electrical equipment is that there are no emissions.

Power selection

Rice. 2

The power of the boiler itself must be chosen, starting from the size of the room. There are a number of mathematical calculations in which you can accurately determine the power required for your premises. To accurately calculate the required power, one must take into account only the area itself, but also pay attention to the height of the ceilings.

If the ceilings are too high, the power of the equipment for high-quality heating should be greater.

In addition, it is necessary to take into account the magnitude of the heat loss of the room itself. This indicator is measured depending on the insulation of the room. Thus, a well-insulated room for heating can use much less money and the required boiler power can be sufficient up to 70 W/m2.

The second point that you should pay attention to when choosing a double-circuit apparatus is the power when heating water. When heating water, you need a unit with a capacity of 24 W / m2. Gas boilers with such power are among the most popular of all types of domestic production.

Choice of equipment: single circuit or double circuit

Rice. 3

The choice of a heating boiler depends on the needs that you need to satisfy. If the supply of warm water to the room is not possible, or if such supplies do not suit you, then when installing the heater, it is recommended to pay attention to double-circuit gas boilers.

Russian wall-mounted gas heating boilers are often used in apartments. Such devices have good power and can work efficiently in small rooms, in addition, they do not require separate rooms for their installation and are completely safe for residents of the house.

Domestic double-circuit wall-mounted gas boilers include a reliable water heating system for space heating, and also have a built-in boiler that can heat water for domestic use without additional external devices. The advantage of double-circuit boilers of domestic production is that they are compact enough for small rooms, which is very convenient for use in an apartment.

Single-circuit units, both domestic and foreign, can heat water only for heating purposes.

Varieties of boilers for the removal of combustion products

According to the methods of removing combustion products, gas boilers can be divided into:

• Chimney.
• Turbocharged.

Chimney gas boilers use natural hoods when removing combustion products. To install such a unit indoors, you must have a high-quality chimney in the room. As for many apartments in our country, and especially in houses that are more than twenty years old, there is no way to guarantee the high-quality removal of combustion products from the device.

Initially, such houses were not intended for the installation of individual heating devices. Thus, when using chimney boilers, there is a possibility of exhaust emissions entering the living space. Such boilers use an open combustion chamber in their work, which in turn requires a large amount of oxygen in the room. Therefore, they are also not recommended to be installed in a residential area, but a separate boiler room is required.

Rice. 5

In this connection, Russian-made factories offer users to choose turbocharged boilers. Turbocharged units operate with a closed combustion chamber. In addition, the positive aspects in such devices are that the removal of combustion products is forced, which guarantees the high-quality removal of carbon dioxide from the living space using the built-in fan.

In most cases, such boilers for space heating require the installation of separate pipes that will be led from the room to the street. Often a coaxial pipe is used, in such a pipe there is to direct the air supply. Exhaust hot gases are discharged through the inside of the pipe.

On the inside, air is supplied to the combustion chamber. A positive point when installing such a device is the absence of a chimney, for them it will simply be enough to bring a large pipe through a hole in the wall to the street.

Types of boilers by installation methods

According to the installation methods, heating devices can be divided into:

• Wall.
• Floor.

Domestic gas wall-mounted boilers are very popular for small rooms and apartment buildings. The bulk of these gas boilers is divided depending on the materials from which it is made. The production of wall units is carried out using a copper heat exchanger, while in the production of floor units a cast iron heat exchanger is used.

The positive aspects when using a copper heat exchanger is their weight, namely the weight of such equipment will be about thirty or forty kilograms. The light weight of such a device will allow you to place it in a small room. In addition, the power of such devices is up to 35 kW, this power is quite enough for a small apartment or even for a medium-sized house.

But there is a small minus in the production of such devices, their service lines are limited, more information on the service line is provided by the manufacturer himself. A positive point in the production of such equipment is their compactness, in such a small device a pump can fit, expansion tank, security group and more.

Floor-standing gas boilers with a cast-iron heat exchanger, despite the longer service lines, require the purchase of many additional, auxiliary elements for installation and further work. You should also pay attention to the weight and dimensions of the device.

The weight of equipment with a cast-iron heat exchanger can be up to one hundred kilograms, and some devices can exceed one hundred and fifty kilograms. Such units take up a lot of space, require installation in a separate room.

The positive point is high-quality and long-term heating.

Profitability of wall-mounted boilers of Russian production

Rice. 6

Among modern gas appliances, the bulk has an efficiency of eighty-nine percent to ninety-three. In addition, the problem of heat loss during heating can be solved by insulating the room itself. If the issue of saving is significant for you, then at the time of heating it is worth installing temperature sensors. Among the many Russian-made equipment, there are a number of, enough, economic options.

For example, when using a temperature sensor for gas equipment you can set two heating modes, one of which will be aimed at heating the room when there are residents in it, and the second option is more economical, which, at the time of the absence of residents of the house, will simply maintain a certain temperature regime, and before the owners return, it will raise the temperature in the room.

Russian-made gas boilers have additional functions, using which you can set such heating modes. In addition, you can set an economical heating mode at the time of sleep. When using such modes of space heating, the savings can be about thirty percent.

Using automation in wall appliances

Safety in the production of devices such as gas boilers for space heating is of great importance. When developing gas boilers high level safety can be ensured by using the self-diagnostic system. The self-diagnosis for gas boilers can automatically turn off the power in such cases as a flame, no or insufficient combustion waste, water overheating, a change in water pressure, insufficient fuel supply or unstable power supply.

Such a security system is needed, especially for wall-mounted heating boilers, which can be placed in a residential area where people are constantly present. Such devices can be found among Russian manufacturers. In addition, Russian production allows such devices to independently resume their work after the stabilization of the situation, or you can set the settings in such a way that users will need to turn it on again. Such security systems are aimed at the complete safety of people.

New types of boilers

Recently, the production of new generation devices has begun in Russia. Such an invention was Russian-made condensate wall-mounted boilers. A positive aspect in the creation of such products is a high level of efficiency. The efficiency level of Russian-made wall-mounted gas units can be one hundred and ten percent.

They are made of stainless steel, can work for a long time. Compared to conventional gas boilers, their service lines have doubled or even tripled. This result was achieved through the use of high-quality stainless steel. Stainless steel wall-mounted gas boilers, with their compact dimensions and low weight, can provide the user with operating power up to 100 kW.

There is only one drawback in the production of such wall-mounted gas boilers; it is necessary to remove processed products from such a device for heating into the sewer.

Choice between domestic and foreign manufacturer

If you have decided on the basic requirements for a wall-mounted gas boiler for space heating, the next step is to choose a manufacturer. The first thing you need to pay attention to is the cost of a foreign-made product. The bulk of foreign-made equipment was created using a large number of electronic devices. The negative point of such a manufacture is its after-sales service.

So, for example, if a malfunction occurs, you will need to call the wizard to remove the problem.

Wall-mounted gas boilers that are designed for heating foreign-made premises require constant diagnostics and programming. Thus, for the maintenance of such a product, it is always necessary to have a master who can come and fix the problem at any time.

Foreign-made wall-mounted gas boilers are not adapted for heating our premises and for the domestic gas supply system. In connection with this, it makes no sense to buy equipment in Russia, which will be much more expensive and rather capricious. Therefore, many experts recommend buying domestic gas appliances for use in Russia by Russian manufacturers.

When choosing Russian-made gas boilers, you can get full advice throughout Russia, find good master, who can not only install your device, but also carry out further maintenance and such a gas appliance can last much longer. In addition, wall-mounted gas appliances in Russia have more demand than abroad, in connection with which their development is paid much more attention. Such units are adapted for heating homes and apartments in Russia.

If you opted for a foreign-made product, then you should take into account the permanent problems with the supply of gas and electrics that exist in Russia. Therefore, you should pay attention to wall-mounted gas units, which, after power-up, can resume their work on their own, such are wall-mounted gas boilers for heating Russian-made premises.

Thanks to this, it is possible to choose a wall-mounted gas unit for heating any room. In addition, the latest combustion systems are used and the efficiency of these devices is at least eighty-nine percent.

LLC Zavod Konord

This plant produces heating systems not only for residents of the country, but also works with foreign buyers. Wall-mounted gas boilers Conord use special technologies in the manufacture of wall-mounted gas heaters. This is achieved with the help of an enlarged magnesium anode. In addition, this technology avoids overheating. Thanks to the use of such technologies, wall-mounted gas appliances from this manufacturer are popular not only in the national market, but also outside the country.

OAO Krasny Kotelshchik

This is an open joint-stock company, which was created on the basis of several separate plants that have been working on the production of heating systems for a long time. On the this moment this plant is one of the largest in the territory of the Russian Federation.

The plant produces a lot of goods under the order of foreign partners. It has many quality marks and distinctions, and most importantly, all goods are produced on the basis of GOSTs.

The choice of heating system is very important. The first thing you need to pay attention to when making such a choice is your safety. You can achieve this by choosing a heating system that has automatic diagnostics. Also, do not forget that the output of combustion products must be carried out with high quality. After that, when choosing heating systems, do not forget that it is necessary to calculate the required power. Choose the device that best suits your needs.

Because in Russian Federation natural gas remains the cheapest and most popular type of energy carrier used for heating buildings and structures; boiler equipment for its combustion is in steady demand. Among the wide range of such equipment on the market, Russian-made gas boilers occupy special place. They take first place main secret success - low cost, accessibility for all segments of the population.

Advantages of boilers from Russian manufacturers

The first thing to note is the attractive price of the products. Any gas boiler of European or South Korean production is significantly more expensive and this is a decisive factor. At the same time, it should be taken into account that the production of gas boilers in Russia is becoming more and more high-tech, using the latest technical solutions.

Equally important are the features and conditions of gas supply inherent in Russia and the CIS countries. Practice shows that imported installations often work unreliably or cannot function at all under these conditions. While manufacturers of gas boilers in Russia adapt their products to the following factors:

1. Insufficient gas pressure in the line. The phenomenon is observed in remote areas with a large length of the gas pipeline and the presence of many consumers on it.
2. Low gas pressure due to wear and tear of obsolete equipment of gas control points.
3. High contamination of the gas with various impurities and corrosion products from old metal pipes.
4. The increased content of water vapor, which, when burning fuel, causes destruction metal elements heating installation.

Most of the gas boilers manufactured in the Russian Federation are able to operate in conditions of unreliable power supply or its complete absence. This plays a big role when choosing a unit for remote regions, where gravity heating systems are often used. In the most simple models Russian manufacturers gas heating boilers are used, which further reduces their cost. Water heating installations, the price of which is slightly higher, are equipped with imported automation elements. However, their number is minimal, safety automation details ensure that the product complies with regulatory documents and nothing more. Great importance also has the cost and ease of maintenance of the equipment.

The qualifications of most gas service specialists allow them to perform Maintenance and repair of domestic boiler plants of simple design. For this reason, the repair of high-tech products from abroad can be a real problem, given the prices of spare parts.

Gas heating units manufactured in Russia have their drawbacks:

1. Relatively short service life.
2. Low build quality of products and materials used.
3. The lack of a large number of useful and important options that provide comfortable conditions operation for the homeowner.

The most popular Russian manufacturers of gas boilers that deserve attention are the Zhukovsky plant (Zhukovsky), the Conord plant (Rostov), ​​the Gazapparat plant (St. Petersburg). To familiarize yourself with their products, it is worthwhile to conduct a brief overview of each of them.

Products of the Zhukovsky plant

This manufacturer has been producing boiler equipment for about 40 years. In the series of gas boilers for heating private houses, there are more than 30 models sold under the brands AOGV, AKGV and KOV. Most of them are produced in three trim levels:

1. Economy - the minimum configuration, which includes Russian-made security automation.
2. In the configuration of the Universal, foreign-made security automatics are installed.
3. The Comfort package, in addition to foreign automatics, is additionally equipped with overheating protection, improved thermal insulation of the case and an indicating thermometer.

The range of thermal power of manufactured units for the home is from 11 to 68 kW. Household Russian gas boilers of the ZHMZ enterprise, for the most part, have a design that works without power supply. It includes a cast iron heat exchanger and a single-stage burner that operates at atmospheric pressure. The ignition method in the budget and medium configuration is manually, in the Comfort version the igniter is ignited using a piezoelectric element. AKGV modifications have an additional DHW preparation circuit for household needs.

Heating installations Conord

Under the CONORD brand, Russian gas boilers with a steel heat exchanger and an atmospheric gas burner are sold. The units are equipped with gas safety valves of two types:

• Italian-made SIT automatic valve;
• thermohydraulic valve.

The range of heating units includes 21 models covering the power range from 8 to 30 kW. Some of these models are equipped with a DHW supply circuit with a flow heat exchanger. All modifications are equipped with a traction control sensor, at the signal of which the automatic valve shuts off the gas.

Under the DON brand, a Russian-made outdoor gas boiler is produced combined type. These are 2 models with a capacity of 20 and 40 kW with a steel combustion chamber, in which an atmospheric burner is installed if it is required to work on gas. Without it, the unit burns wood or coal and is completely independent of electricity.

Boilers manufactured by the Gazapparat plant

Under the Neva Lux brand, you can purchase an inexpensive wall-mounted Russian gas boiler of this enterprise located in St. Petersburg. Products are not much inferior to foreign counterparts, since they have a wide range of options and safety and automation functions. The heat exchangers in the units are steel, there are modifications with a flow heat exchanger for the needs of hot water supply. The air supply method is forced, by a fan - a smoke exhauster through a coaxial chimney.

The burners used in Neva Lux boilers can change operating modes at the command of the controller. The power range of produced wall-mounted boilers is from 10 to 35 kW. Automation and control components are made in Europe, which makes the operation of the heating plant economical and reliable. The set of boiler automation functions is as follows:

• burner flame control;
• traction control;
• circulation pump;
• pump protection function against jamming in the summer;
• fan speed control;
• touchscreen;
• automatic electric ignition;
• possibility of programming for 7 days.

Conclusion

When choosing a boiler for your home, you should pay attention to the products Russian enterprises. The disadvantages of gas boilers are smoothed out by low cost, bringing the price-quality ratio into line, that is, Russian products honestly work out the money spent on them. Some of them, in many respects, began to approach European or South Korean counterparts.

Reliability, performance, adaptation to domestic operating conditions, all these parameters distinguish a Russian-made gas floor boiler. At the moment, domestic and industrial boiler equipment is produced by more than ten different manufacturers.

Types of floor-standing gas boilers manufactured in Russia

In the Russian Federation, several lines of heating units are produced, differing in the type of heat exchanger, the number of circuits and the dependence on the availability of electricity. When choosing a suitable model of boiler equipment, first of all, pay attention to the material of the water circuit.

The primary heat exchanger is made of cast iron or stainless steel. Each metal has its own characteristics and thermal characteristics:

• Cast iron boilers are characterized by good heat dissipation and high performance. Cast iron boilers have a long service life, reaching 35-40 years. The material is resistant to aggressive substances and condensate.
  The disadvantages of boilers with a cast-iron heat exchanger are the high cost of production associated with the complexity of the casting and assembly process. The equipment is heavy and sensitive to mechanical damage.
  The cast iron heat exchanger is assembled in sections and, if necessary, repaired by replacing the segment.
• Boilers with stainless steel heat exchanger- stainless steel combustion chamber, cheaper, lighter weight and relatively simple manufacturing process. The term of operation is 12-15 years. Stainless steel boilers are in constant demand due to their reasonable cost.

The best boilers are equipped with a cast-iron heat exchanger, but the complexity of the technological process and the high cost, often “unbearable” for the buyer, have led to a reduction in the number of units produced. Cast iron boilers today are not included in the product range of many domestic manufacturers, or are presented in a small assortment.

After choosing the heat exchanger material, attention is paid to the number of gas boiler circuits. The presence of additional functions of the heating unit depends on this parameter.

Dual circuit

Domestic floor-standing 2-circuit gas heating boilers are designed for simultaneous heating of the coolant for the heating system and hot water production. Design feature with two circuits:

• The presence of two heat exchangers- during internal structure a primary heat exchanger made of cast iron or stainless steel is installed. The secondary circuit is made of copper, in the form of a coil encircling the primary heat exchanger.
• Heating of the heat carrier and hot water supply- floor gas double-circuit boilers of Russian production, operate in alternating mode. When DHW is turned on, heating of the heating system stops. The heating of the coolant during this time drops by 1-2 degrees, which is practically not felt in the room.

Each double-circuit boiler has throughput DHW. The parameter indicates how much the heating unit can heat hot water in one hour. In heat engineering calculations, the required power reserve equal to 20-30% is taken into account.

single circuit

Russian-made floor gas single-circuit boilers are designed exclusively for efficient space heating. Some models provide for the possibility of further modification. To a single-circuit boiler, you can connect a remote boiler indirect heating, to provide household hot water residents of the house.

Thermal units have several differences and thermal characteristics:

• High performance – thermal energy is spent solely on heating the coolant. Boiler equipment fully complies with the technical documentation power. The performance of boiler equipment is practically unlimited.
  If desired, you can order a heat generator up to 250 kW. If necessary, several boilers are connected to a single network to increase the total power to several MW.
• Reliability - in the device of a single-circuit boiler, there is practically nothing to break. The heat exchanger, even in the conditions of hard water used as a heat carrier, continues to maintain its efficiency throughout the entire service life.
• Versatility- single-circuit units, operate using water and antifreeze as a coolant.

Single-circuit floor-standing gas boilers made in Russia are fully adapted to the quality of the coolant, the gas pressure in the line and other system parameters. Boiler equipment is installed for heating large areas, as well as where there is no need for hot water.

A heating scheme has become widespread, in which, to a single-circuit unit of indirect heating. This solution, allows you to get a large number of hot water with minimal gas costs. DHW heating carried out by means of a heated coolant of the heating system.

Dependent and independent of electricity

Another significant parameter that is paid attention to when choosing a suitable model of boiler equipment is the dependence on electricity. There are two kinds heating equipment:

• Non-volatile- ideal for space heating in conditions of frequent power outages. The principle of operation is based on the use of physical phenomena for control and monitoring. The operation of the burner, which, when heated, generates a low-potential voltage sufficient to hold the gas valve open.
  Power and operation are controlled without electronics. The operating mode is set manually, by means of a mechanical device. Heating of the heat carrier is carried out by the method of switching on / off the gas supply. In constant mode, the pilot burner - igniter is working.
• Volatile– are the most economical boilers. The burner automatically adapts to the operating parameters of the system. Domestic boilers are supplied with imported automation. The housing is provided with a pump for circulation of the coolant.
  Automation analyzes the operating parameters of the system: the intensity of draft and air supply, gas pressure and heating of the coolant in the heating system. Starting is carried out by means of electric ignition.

Non-volatile heating devices, connected to heating systems open type coolant. An additional pump installed on the return of the water circuit is allowed.

Volatile boilers are equipped with a two-stage burner operating in two performance modes: at 30-40% or 100% of the rated power. With such a design solution, there is no need for a constantly working igniter. Gas savings are 25-30% compared to classic non-volatile models.

With open or closed type combustion chamber

The fundamental difference between the design of boilers with an open and closed type combustion chamber lies in the circulation of the air flow inside the device, which affects the thermal and production characteristics:

• Boilers with an open combustion chamber- air, for the manufacture of a gas-air mixture, is taken directly from the room used for the boiler room. Combustion products are discharged naturally through a classic chimney.
  The high requirements regarding the operation of atmospheric burners. The minimum area of ​​the premises, the presence of a window, the height of the ceilings, etc. are negotiated.
  For the normal operation of the heat generator, it is provided supply and exhaust ventilation. Due to the principle of gas combustion and removal of combustion products used, boilers with an open combustion chamber are called convection or atmospheric.
• Boilers with closed combustion chamber- the burner is installed in a sealed housing. To prepare the gas-air mixture, air supplied from the street is used. Combustion products are discharged by force. The boilers are equipped with a turbine - a fan that provides the necessary circulation of air masses. Air intake and flue gases are carried out by a chimney.
  The current regulations allow the installation of boilers with a closed combustion chamber in any non-residential premises:, (if allowed by the local authorities of Gaznadzor). The unit can be built into kitchen furniture or closing with a decorative panel.

The thermal characteristics and the principle of operation of the boiler are directly related to the design features: the material and device of the heat exchanger, the combustion chamber and the installed automation.

The choice of domestic outdoor gas boiler

After choosing a heating unit according to the characteristics of the internal device and design, a boiler is selected according to the manufacturer's brand and cost. Comparative characteristics and a brief description of the products manufactured by popular manufacturers will allow you to decide on the choice of heating equipment that is optimally suited to the parameters of the heated building.

The comparison of boilers includes only those models that are in constant demand among the Russian consumer and are distinguished by good thermal performance and performance.

Of course, this list does not contain all brands of gas equipment that are popular with domestic consumers. The proposed heat generators differ in the degree of automation and design features.

Price framework for domestic floor-standing gas boilers

Prices for Russian-made floor standing gas boilers range from 11 thousand rubles to almost 70 thousand rubles. What affects the cost of the heating unit:

• Type of heat exchanger - cast-iron boilers with two heat exchangers will cost the most.
• The number of circuits - a single-circuit unit costs approximately 10-15% cheaper than a double-circuit analogue.
• Complete set - installation of Italian automation and a heat exchanger manufactured by a European manufacturer significantly increases the cost of production.

The pricing policy is influenced by the “hype” of the brand. So, the cost of Rugas, BaltGaz, Termotechnik boilers will be an order of magnitude higher than that of Ochag, Pechkin, etc.

Pros and cons of Russian floor-standing gas boilers

Even the most popular Russian-made floor standing gas boilers have their drawbacks, which become obvious when comparing the thermal characteristics of domestic and foreign products:

• Advantages - Russian manufacturers are well aware of what consumers face during heating season. All complaints are taken into account when developing new designs and models. Automation works at almost any gas pressure, the burners maintain a stable flame intensity, the heat exchanger can withstand hard water.
• Disadvantages - despite all the listed advantages of domestic products, the rating of boilers in terms of reliability and efficiency is occupied by products of German and Czech manufacturers. Automation of the operation of Russian boilers was completed with shortcomings. There are no models with modulating burners and precise microprocessor control.
  Gas consumption, in the lines of some domestic heat generators, is almost 30% higher than that of European counterparts. Appearance and operating comfort, Russian boilers are also not at a high level.

What is the difference between domestic and imported outdoor gas boilers

Modern boilers of Russian factories, in terms of their thermal characteristics, have come close to European quality standards. Feedback on the operation of domestic domestic boilers testifies to positive trends. Despite this, there is a difference between products manufactured in the EU and Russia.

It is worth considering just a few indicators and parameters:

• energy efficiency- Russian heating devices with the highest efficiency, reach 92%, for foreign analogues, such boilers operate with an efficiency of 98%.
• Service life - the boiler with a cast-iron heat exchanger will last the longest. Russian equipment has an estimated service life of at least 25 years. German equivalent, 35-40 years old.
• Automation - the main range of Russian boilers, still uses non-volatile automation, which, in the conditions of domestic energy supply, is a completely justified step. For this reason, it is clearly not necessary to talk about the comfort of operation. Manual power control leads to excessive consumption of gas.
  Atmospheric burners are not able to provide the optimal proportions of the gas-air mixture necessary for complete combustion of the fuel without residue, which leads to the appearance of carbon deposits in such an amount that cleaning of the nozzles is required before each heating season.

Boilers of Russian production, better retain their performance in the conditions of domestic operation, but lose to foreign counterparts in efficiency and autonomy.

On this tab, we can define certain structural units for the desired garage. The garage heating assembly has some components. Each element is very important. Therefore, the selection of each element of the system must be done correctly. The heating scheme includes a connection system, pressure-increasing pumps, fasteners, pipes, thermostats, batteries, an expansion tank, collectors, an air vent boiler.

Russian-made gas floor standing boilers are also produced by ZIOSAB Closed Joint Stock Company. The plant produces over 15 models of boilers. The plant produces boilers, both of its own production and under the license of the Finnish company Finraila.

CJSC "ZIOSAB" produces boilers in accordance with the world standards of boiler building, both minimum power and rather powerful boilers with a value range up to 3000 kW.

According to consumer reviews, Russian-made gas floor-standing boilers are not able to compete with European manufacturers.

Russian manufacturers of gas boilers

In Taganrog, there is a plant for the manufacture of boiler equipment - Lemax. Models produced at the plant consist of imported components and operate on both gas and solid fuels. Lemax produces models of boilers with one circuit and double-circuit models. The most popular models of the manufacturer Lemax: Leader, Gazovik, Plus.

In Russia, there are other companies manufacturing heating equipment: the Mimax plant (Taganrog), the Rostovgazapparat company.

Complete set of domestic gas boilers. Types of boilers

A wall-mounted boiler is usually considered compact, this is, to some extent, true. For example, Buderus floor gas boilers will be more than 30 percent of the wall line of the same manufacturer. These devices have three mandatory element: gas burner, fittings for adjusting the gas supply and the heat exchanger itself. You can find steel and cast iron heat exchangers, but due to their greater weight and high cost, they still prefer to replace them with copper ones. Also, do not forget about the built-in automation of the boiler.

Additionally, any wall-mounted device contains a built-in pump that drives water around the circuit, an expansion tank and a safety valve. Mandatory system of control, protection and self-diagnosis. She "vigilantly" monitors the state of the fuel: in case of leakage or lack of gas, the automation stops the work, gives a signal about a malfunction. The Zhukovsky floor-standing gas boiler (or a floor-standing unit of any manufacturer) will work in the same way.

Mini-boiler rooms located on the floor have, in fact, the same device as wall-mounted units. They are based on the same heat exchangers, usually installed from a copper composition (with operational errors and for reliability, they often use and steel structures). Two types of burners are installed in gas floor heating boilers: atmospheric and pressurized (also called hinged, fan, replaceable). Atmospheric ones are somewhat cheaper, they work silently. The hinged structure is more powerful, works with full dedication, but the price for it is always set higher. As a rule, Ferroli boilers are bought with such parameters - which have proven themselves both in quality and design.

Outdoor gas boiler: how to choose the right one

The choice, first of all, should be made taking into account both the proposed area for heating and the power level, which does not always mean the same thing. When there is not enough space, also in small rooms located in middle lane, you can do with an ordinary mounted boiler. But in the case of a house built in a cold climate with a large need for heating, it is better to choose a more powerful unit. For floor gas heating boilers, prices are higher, but the efficiency of work will be appropriate.

By the way! Wall-mounted devices are considered the cheapest (installation can cost up to $ 1000), easy to install, suitable for small spaces.

Quite often they are single-circuit, which allows only heating the room, for example, you need a boiler to heat water. Of course, there are single-circuit floor-standing gas boilers, but even their heating power is much higher. Such a mounted boiler will suit the owners small house that use other means to heat water: a boiler, a column, a fireplace with a water circuit, and so on.

Most owners of private households with an area of ​​​​200 square meters or more will prefer floor version with power control. These most reliable devices (with the same “stuffing” as the mounted unit) require maintenance about once every three years, and provide more power. Their cost is higher, especially if it is a gas double-circuit floor or wall-mounted boiler, in principle it does not matter, one piping of a floor gas boiler will cost at least 500-600 USD. but the subsequent minimum expenses for household services compensate for this.

Generally divided into two areas

Floor-standing units with a dual circuit will be beneficial to owners of large houses that were "conceived" without being connected to a central system initially. A single-circuit floor-standing gas boiler is not the most convenient option, since you have to branch the system even more when you turn on, for example, a column. The dual-circuit system, although it does not allow you to work in the heating and water heating mode at the same time, this is leveled out thanks to the simple laws of physics.

Russian floor-standing gas boilers today are presented in a wide range of products, among which you can find enough inexpensive options acceptable to many domestic families. Tellingly, today these neat devices are not "sillier" than their foreign counterparts. It is also worth noting that in the domestic market, industrial gas boilers are gaining no less popularity than domestic ones.

By the way! They are equipped not only with high-quality boards, but also with weather-dependent automation, which allows you to keep the temperature in the house from fluctuations even before the moment when it changes inside the room.

For example, Lemax floor-standing gas boilers with a similar modern thermostat “thinly” feel weather. To do this, their temperature sensors are also taken out into the street. The devices measure the temperature there, and already according to these indications, the floor boiler can be reprogrammed in advance for changes in the microclimate in the house itself.

A little more about Russian production

Other Russian high-quality outdoor gas boilers "Buderus" allow you to adjust the "weather in the house" for some period of time, setting indicators. For example, during the week, the owners will not be at home more often than usual, so you can reduce the power of the boiler. And for the Christmas holidays, all family members will gather in the family nest - the boiler is programmed to work with maximum efficiency. This greatly simplifies the life of the owner of a private house: he does not need to worry about the temperature in the house, he only needs to spend 15 minutes on weekends setting the thermostat.

Reviews of domestic floor-standing gas heating boilers are usually positive. This suggests that Russian craftsmen have long learned to produce beautiful, high-quality and, most importantly, reliable products with excellent automation. Also, the purchase of such boilers can be much cheaper, and the maintenance of Russian equipment will be carried out by specialists from the manufacturing plant itself. They know their product better than anyone else, and you won’t have to wait for repairs for a long time - all spare parts are “at hand”, and not in a foreign company.
