*Overview of the best in the opinion of the editors of the site. About selection criteria. This material is subjective, is not an advertisement and does not serve as a guide to the purchase. Before buying, you need to consult with a specialist.

Hot water is an essential attribute for the normal life of a modern person. Many residents of apartment buildings use it, unaware of all the complexities of heating. And only during interruptions in water supply the question arises of buying an autonomous heating device. Residents of private houses usually solve this problem at the construction stage, in the future the water heater is serviced and changed. What criteria should an ordinary consumer be guided by in order to choose a reliable device for heating water?

How to choose a water heater

1. Energy source. First of all, you should build on the existing source of energy. Most often it is electricity or gas. If both energy carriers are available, then all the pros and cons of each of them should be evaluated.
2. Type. The next important point will be the choice of the type of water heater. Accumulative models have a tank of a certain capacity, where water is heated and stored. Flow devices are characterized by high power, because they must heat the flow of water in a short time. If there are secluded corners in the house or apartment where you can hide the storage tank, then it is better to give preference to this type.
3. Heating element type. In electric boilers, "wet" or "dry" heating elements can be used. The principle of the boiler is used in devices with a "wet" heating element. If the water is of high quality or filtered, then such boilers will last a long time. Otherwise, you should give it to a water heater with a "dry" heating element, although it costs more. The heating element is hidden in a special flask. It does not come into contact with water, so it has a longer service life.
4. tank material. The type of material from which the storage tank is made also affects the durability of the water heater. Stainless steel boilers are considered the most durable, but due to availability, consumers often choose enamelled steel. Modern coating technologies include the introduction of silver ions into the enamel layer, due to which the fight against corrosion and bacteria is simultaneously carried out.
5. Weld. The weak point in tanks made of different materials is the welding seam. So that it does not collapse during operation, anode protection is used. And if the magnesium anode has to be changed regularly, then the titanium protection is thrown away along with the water heater.
6. tank shape. Deciding on the shape of the tank is quite simple. Rectangular designs look more compact, and barrel-shaped models are cheaper. Recently, slim models have become popular. They have one of the sides (diameter) smaller, which simplifies the placement of the device in a cramped room.
7. Mounting method. According to the mounting method, there are vertical or horizontal boilers. Some manufacturers have developed universal mounts that allow the user to independently select the optimal position of the water heater. Most household appliances have a wall mount, and industrial devices are installed on the floor.
8. Control system. Each water heater has a control system. The simplest is the mechanical method. It is practical and affordable. The disadvantage is not quite accurate setting of the water temperature. Electronic control increases not only the comfort of use, but also the cost of the device. Thanks to the display and touch buttons, you can specify the exact temperature range, and then follow the readings of the device.
9. Additional functions. A number of additional features are reflected in the price of the water heater. Overheating protection directly affects the safety level of the device. With the help of a timer, you can save a lot of money by setting it to work in night mode. The rate of cooling of water will depend on the thickness of the thermal insulation. In pursuit of compactness, it is important not to forget about this moment.

Our review includes the best manufacturers of water heaters. When determining the winners, the opinion of experts and reviews of domestic consumers were taken into account.

Attention! This rating is subjective, is not an advertisement and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Russia is one of the leaders in the production of technological equipment for heating water and maintaining its temperature for a long period. The Russian manufacturer installs new, improved standards, and their design, compactness and cost are their obvious advantages. Most models of water heating devices of the best Russian brands are supplied to the market with storage tanks that are made of stainless alloy steel.

classic traditional Russian water heater the following features and benefits:

• high power productive heating unit;
• anti-corrosion tank for water heating is made of alloyed stainless alloy;
• automatic mode during autonomous operation does not require regular technical inspection.

modern industrial Russian accumulative boiler to carry out heating of water with a volume of 10,000 liters. Such powerful modern devices are controlled electronically. A standard storage industrial Russian boiler can have a combined design that allows the operation of a device connected to the electrical network or to a traditional existing heating boiler.

Consider today the brands produced. We hope the review will be interesting, the time spent reading is useful for the lost. We recommend taking goods for money, the market is devoid of frank outsiders, the latter have long been outdated by competition. We do not set ourselves the task of finding a bad brand, we will make an excursion into what models the manufacturer produces. From the described position, we are going to answer the question of which brand of water heater is better to buy. Let's get started.

Water heaters Ariston

Ariston's sales account for the lion's share of the market. The official websites of the manufacturer are represented by 27 options. Mostly English-speaking. In our opinion, sorting is slightly lame, let's make up for the shortcoming.

Electric storage water heaters Ariston

Electric storage water heaters are standard in terms of volume. Models are available with a capacity of 10 - 100 liters. There are three types of tank cover:

• enamel;
• stainless steel;
• titanium.

It is clear that the last line will be more expensive. Ariston enamel is dotted with silver ions. Know-how of the corporation, technology that suppresses the growth of harmful bacteria. Who does not know - water is taken from the upper quarter, the bottom is considered a stagnation zone. These areas need silver ions. Is it a useful innovation? Undoubtedly! Each firm is trying to creatively invent a fresh composition of enamel, carefully guarding the secrets of research laboratories.

Ariston's problem is limited by the lack of advertising in Russia, the manufacturer presented the most models exhibited by Yandex Market. We do not recommend ignoring Ariston, although the official website of the company is mediocre in terms of search convenience. According to the parameters of Yandex Market, it was determined that the company, having put up 200 models, did not present any with a dry heating element. Is this good or bad. We conclude: the manufacturer is self-confident: he avoids introducing something new. Trade is arguing - priority is given to conservative policies.

We wanted to draw the attention of readers to something else! Ariston has over-represented large-capacity floor standing electric water heaters. These are good when you are afraid to get, mastering the toilet, on the hump with a weighty container. Let's say more, where there is enough space, put a bulky water heater only on the floor. Americans give security a leading role. The United States is rarely too lazy to scold out of envy, the developed world has heard a lot about the manufacturability of the New World. Let's leave politics. Ariston has several lines of floor water heaters, pay attention.

Gas storage water heaters Ariston

The Ariston company showed another feature - the absence of instantaneous electric water heaters. The minimum volume of the tank is 10 liters. But the catalog is more colorful than a real imitation of the American way of life. They described the process of installing a storage gas water heater, a smart solution for apartments supplied with natural gas. Overcoming the low specific heat of combustion, the result is excellent. Americans equip individual cottages with aggregates.

Ariston produces models with power below 30 kW. Not a water heater - a boiler. We believe that the difference between the two types of devices is limited by the amount of heat loss. And the winner is unknown. Let's say more, some people specially replenish the heating circuit with a store in the form of a large capacity. In our case, the trough will also heat water. Efficiency comparable to a boiler makes you think!

• heating reaches 75 degrees Celsius (the highest battery temperature, according to GOST);
• execution floor;
• tank 275 liters;
• weekly cycle programmer.

An inlet pressure of 0.5 - 8 atmospheres will allow the device to be used everywhere. Including heating circuit. Is it possible to do so. Please consult with the firm. The price bites (200,000 rubles), the quality speaks for itself. The water heater can supply the faucets of a private house. Intensive consumption is implied, 30 kW is enough for 5-6 showers in real time. We simply explain - the proposed non-apartment option, semi-industrial equipment of a small hotel.

Consider using waste gases. Try to build a kind of dark infrared heat exchanger in the chimney. There would be an almost complete return of the energy generated by the combustion of gas. What we praise Ariston. The firm has saved budget and professional solutions. If in dire need, take without fear. Spare parts are on every corner, buying a thermostat for an Ariston water heater will not be a problem, heating elements, magnesium anodes.

Water heaters Thermex

Termex boasts of the glory of one of the best brands in Russia for a reason. Water heaters of the famous manufacturer are suitable for Russian realities. Designed with purpose. The company avoids producing gas heaters, they left happiness to the domestic brand Neva, switching to market research.

Termex produce water heaters of the so-called indirect type. Basically boilers. Water is heated by an external boiler, built-in electric heating element. If the spiral gives 1.5 kW, the heat exchanger covers the named value ten times. We see a typical boiler of relatively small volume. Using a home boiler that produces water at a temperature of 70 degrees Celsius (standard heating standard), we direct heat to the shower circuit. Agree, great. More tempting price. 20,000 rubles for a boiler is inexpensive.

Buy a horizontal water heater from Termex. Sometimes it is convenient when installed under the dishwasher where nothing else fits. Pay attention to the flow models of this manufacturer. You will see options even for two showers (or shower + sink). The necessary connectors for installation are included in the design. Power reaches 8 kW, an atypically high figure. The buffalo quota will be pulled by a rare electrical panel. We believe this is a model for small hotels, where the rooms lack individual showers. Those who wish will wash themselves in common booths.

Emphasize! The market has not provided analogues to Termex flow models. Think back to wondering what brand of water heater to buy.

Water heaters Electrolux

Among the highlights of Swedish heaters we see "dry" heating elements, avoided by Ariston. Note to fans of new technologies: guaranteed protection against scale. However, magnesium anode deposits will still be present. If you take a water heater without protection, you risk the tank body. Networks often contain copper parts, an elementary neighbor's instantaneous water heater will pose a threat to equipment. Chains of electrochemical corrosion are laid over long distances, the electrical resistance of water diluted with hardness salts is small.

Electrolux gave way to Ariston in the segment of storage gas water heaters, but came to grips with the columns. When searching, limit your attention to cheap gas water heaters. Electrolux does everything wisely, take it without hesitation. Geysers manufacturers have at least three degrees of protection.

For 3500 rubles you will find a faithful assistant with a power of 20 kW. Two (even three) showers are enough. Master natural gas, you will surely save money.

The geyser demonstrates two troubles:

1. The pilot light is constantly burning, annoying the zealous owners. Some modern ignition models contain electronic ones, there is no ignition group. However, the water heater is expensive.
2. The water will start to warm up gradually. First, the flow must gain strength in order for the sensor to work. Therefore, you will have to wait. Not everyone will like this state of affairs.

In the simplest models, the temperature is not controlled. Power is pre-calculated, and this is not necessary.

The characteristic features of equipment of three types are given. Enough to initially select models. Try to look for products from world famous manufacturers. You don't have to run around bulging your eyes if you want to buy a water heater thermostat. Saving time is not the last argument, given the ratio of the cost of spare parts and products.

A couple of numbers for thought. Will help quantify water heaters:

1. 200 liters with a heating element power of 2 kW are heated for 8-9 hours, reaching a temperature of 70 degrees.
2. Water consumption when taking a shower is above 3.5 liters every minute.
3. One shower procedure takes 15 liters of water from men, 25 from women.
4. For satisfactory washing in the shower, you need an instantaneous water heater above 4 kW of power.
5. For a couple, a storage water heater with a capacity of 50 liters is suitable, for a family with a child - above 80 liters.
6. Try to avoid hanging water heaters on the walls yourself. It is necessary to more accurately calculate the strength of the wall, not every Russian engineer can do it.
7. You need to buy a thermostat for a water heater, try to take exactly the same. Manufacturers vary the maximum water temperature. Compare Bosch, Ariston - make sure.

Consider the above information, the selection process will seem easy. Perhaps you decide to buy a water heater for the aquarium. However, more about that another time.

Where to start buying a water heater

The Internet is periodically supplemented with myriads of angry articles claiming that the heater of one company or another has failed. Found one review regarding Termex. We affirm that the comments below are fabricated by competing firms, at least in part. Therefore, today we’ll talk about how to properly start operating a water heater so as not to blame the manufacturer later. People sometimes come across a marriage, more often the buyer lacks knowledge, the ability to properly operate household appliances. Which company to buy a water heater is the tenth thing, if you forgot the trivial wisdom.

The above applies to water heaters, any installed household appliances:

1. Washing machines.
2. Dishwashers.
3. Water heaters.

Usually the company sets certain conditions for warranty service. Each self-respecting manufacturer will provide a free phone number through the official website, by calling which you will find out the details of warranty service. Regarding air conditioners, installation work is carried out by a certified organization. In any case, each time the conditions are new. What to do if during installation the tank coating was damaged, the wall rotted. We parody the hosts Who wants to be a millionaire:

• Bite your elbows.
• Blame the manufacturer.
• Flood forums with angry reviews.
• Recognize mistakes, continue to do the right thing.

The answer is obvious, no one acts in life according to the last option. They show an eloquent photo of a steel-colored “copper” heating element, they complain. The authors immediately ask three questions:

• what is the hardness of the water;
• magnesium anode installed;
• the heating element was tested for insulation resistance.

The heating element breaks with overheating, if the insulation is broken, water penetrates inside, boils, increases in volume, looking for a way out. Inside the heating element, there is a nichrome wire (fechral) under a voltage of 230 V. Water begins to rapidly decompose, forming hydrogen and oxygen, increasing pressure. How did the liquid get inside?

Heating elements of water heaters

The tightness of the outer shell is broken. A manufacturing defect that needs to be identified in time is the careless operation of a steel heating element without a magnesium anode. In the first case, at the startup stage, you perform a check.

According to the mind, the factory should control. Firstly, Russia, secondly, individual products are damaged during transportation, and thirdly, booing a mountain of crayfish. In any case, check the insulation resistance of the heating element in a tank filled with water. See how to do:

1. The water heater is installed in place, connected to utilities.
2. Avoid plugging in the appliance, fill the tank with water. The valves of the installation composition of the equipment are unlocked.
3. Then you need to slowly open the bathroom mixer (shower) to let the air descend.
4. After a long hiss (determined by the volume of the tank), a thin stream of water will flow.
5. Close the valve in the bathroom (shower).

Checking the insulation resistance of the heating element of the water heater under operating conditions

The water heater is ready for operation, avoid supplying electricity. It is suggested to keep under pressure for 5 minutes or longer. Perhaps a few hours, the presence of microcracks will allow water to seep inside. In parallel, dial the company's support service, find out the insulation resistance of the heating element. Typically 20-25 MΩ. We assume that the figure may vary slightly. We take a tester, remove the front panel (depending on the model of the water heater), lean one probe against the body of the heating element, the second to any electrode (do not confuse it with a thermostat, ring with a plug if in doubt). We observe infinity (20 MΩ exceed the limits of a typical household appliance). Any other, even a very large figure should make you ask a question to the support service, a specialized forum.

Note! Insulation resistance is measured with a voltage of 500 volts generated by a special generator. The above described a simple check with a Chinese multimeter. There is professional equipment, try factory methods.

Having fixed a low insulation resistance, immediately call the company's specialists, change the device according to the warranty.

Small indications testify: water got inside, the case smells of fried. If the first stage went well, we recommend that you carefully turn on the heating coil. Please note: if there are two spirals, the insulation is checked for each separately. And you can turn it on together. As soon as the device works out the mode, turns off, unplug the cord from the outlet. After we remove the front panel again, we call. The logic is this: the temperature has risen, the materials have changed geometric dimensions, which means we will check the tightness. Then we proceed according to the old scheme.

Technical service workers will not force an honest person to buy TENs for a Termex water heater once again. In this case, it would be nice to capture the detected defects on film (video). The problem expressed by practitioners: the company makes you pay for the installation of the device to a professional. Violation of the rule voids the warranty.

Harm of scale to the heating element of the water heater

Why was hard water mentioned in the first place? Found, confused by the network, an angry review affecting the issue. The phrase slipped: cleaning is carried out once a year. Where did the fixed term come from? Instruction? The Chinese copied from the left equipment. The frequency is determined by the frequency of turning on the water heater, the value of water hardness. Whistling, buzzing are heard, incomprehensible vibrations appear that accompany the operation of the device - it's time to drain the water, carry out extraordinary maintenance. Laziness! Then there is nothing to complain about later that buying a Termex water heater means losing in advance. The magnesium anode does not protect against scale, it prevents electrochemical corrosion.

Why do you need a magnesium anode for a water heater

Magnesium anode protects steel from copper aggression. Steel are made:

1. The protective layer of the heating element (we will see by the color of the shell).

A steel heating element - without a magnesium anode will break if there are upstream (and even downstream) copper pipes, fittings, instantaneous water heaters. A chain of leakage of atoms is created, be ashamed to complain later, to discuss biasedly which company is better to buy a water heater, because this one, you see, is bad.

What is check&bypass valve

During the operation of the water heater, there is a constant cyclic expansion and contraction of the tank. The thermal expansion coefficient of water is quite different from that of steel. Excess pressure is released using the bypass valve. In the absence of such, water will quickly destroy the protective coating of the tank (seams), corrosion will begin. As a result, the tank will break, the flood will begin. To prevent this from happening, read the instructions carefully.

Which manufacturer of water heaters to prefer

The above was a rough hint: there are no bad manufacturers of water heaters in nature. There are unscrupulous installers, illiterate users. If done right, the technique will work 99% of the time.

Shower water heater

They missed the methodology for assessing scale build-up, there is no efficient simple method. Just check periodically. It is enough to control the situation during the year to gain useful experience for the region for the rest of its life. Further simplifies operation.

No need to sit, think about which company to buy a storage water heater. Just choose a product according to the parameters, before buying, call the manufacturer, specify the terms of warranty service. As a rule, the installation of such a simple technique does not cost exorbitant money. Perhaps some manufacturers trust the client with the process of work. Ask. Then follow the instructions, check the equipment according to the diagram, evaluate the result.

Choose a water heater according to the parameters

A simple calculation will help any reader of the portal VashTechnik to find out the need for power, volume of water. It is known that the specific heat capacity of water is 4200 J/kg K. Heating one liter of water per degree consumes 4200 J of energy. Traditionally, water at a temperature of 8 degrees Celsius usually flows from a tap. You can easily calculate the power of the heater needed by an apartment that plans to enjoy the benefits of civilization.

Record the amount of water spent in one session of taking a bath with a meter, how long the process continues. At the output, you will receive a displacement every minute. Using the figure, we find the power according to the formula:

N = 4200 x L x 42/60,

L - water consumption every minute, expressed in liters.

Suppose we wash ourselves with water at a temperature of 50 degrees Celsius, the difference with the riser will be 42 degrees. A weak pressure is created by 3 liters per minute. Based on the given conditions, we get a power of 8.8 kW. It will be a fairly strong shower jet, and the formula has been fed harsh initial conditions. If we take summer, the initial temperature sometimes reaches 15 degrees, for some 45 degrees is enough to wash. In this case, a third is subtracted from the difference. 4–5 kW are obtained, which are considered the minimum consumption for an instantaneous water heater.

Guided by the above formulas, the reader will calculate the required power at home. This also applies to storage water heaters. But the formula is tweaked to find the time it takes for the tank to reach condition. Offhand 8 - 9 hours per 200 liters. You can get a different figure depending on your needs, initial data. Better than believing dealers touting the product unfounded, personal preferences differ from the standards. After setting the initial conditions, buy an electric water heater exactly the one you need. Note that in a couple of days it is easy to determine the family's need for water, be guided by the calculation instead of the assurances of the sellers.

Water heaters equipped with a dry heating element

It is not easy to choose which water heater to buy in an apartment, watching today's abundance lining the counters. We will help with advice, we hope to avoid repetition in the reviews - read everyone! In any there will be new, hitherto unknown. Not surprising considering how many varieties there are in the store. Let's say right away that in 90% of cases, residents choose the first option from accumulative and flowing ones, but you need to think about what type of energy the device will work on. There are no problems if the design documentation of the house provides for a built-in chimney, which is pre-equipped at the construction stage. God ordered to switch, taking a water heater, to blue fuel.

First, what is TEN. The abbreviation stands for - tubular heating element. It is incorrect to call a dry heating element a set of letters. In a typical case, a tubular heating element is manufactured as follows:

1. A nichrome thread is taken, placed in the center of a metal (steel, copper) tube.
2. Heat-resistant powder is poured inside.
3. This is followed by a rolling step, the tube is passed through smaller holes.

As a result, the heating element takes shape. Nichrome, separated by an insulating layer of powder from the shell. The ceramic coat is compressed tightly, the tube is cut into pieces, from which a spiral is bent. Standard option. When manufacturing a “dry” heating element, the plant surrounds the spiral with a set of hollow ceramic tubes. The following result is achieved:

As a result, the probability of a heater with a “dry” heating element failing is minimal, and the device needs to be serviced less often. Scale, electrochemical corrosion are the main enemies of heating elements, the Tatars are neutralized by using a layer of ceramics. We believe that you can choose Electrolux from a couple of lines of storage water heaters. There would be money. To evaluate the range of choice, we recommend visiting the Yandex Market. To select the desired models, set in the parameters:

1. The type of water heater is accumulative.
2. The heating method is electric.
3. Dry heater - yes.

Hundreds of models will appear, some of which you can buy with promotions that provide a discount. 8000 rubles for 80 liters of an excellent tank (you can buy an Atlantic water heater for 7300). Agree, it's cheap. Ordinary models cost the same. The advantage of Yandex Market: you can quickly find a device for a promotion.

We will not hide, we ourselves use similar methods, examine Eldorado, Vikimart, try options for exchanging old equipment. Buy a water heater for free. The thing will still be good, you need to work hard to properly check the purchase before installation.

1. First, worry about the warranty in advance. Without the labor of service centers, a pile of metal is not worth a penny; not everyone can fix a water heater with their own hands. In case of self-detection of marriage, the goods can be returned.
2. The conditions have been clarified - start bidding, arrange delivery. Find out who will install the water heater, whether the event deprives the warranty rights. Case of life: the installers could not correctly remove the locking bolts of the washing machine! Household appliances do not like barbaric treatment.
3. The water heater is installed, let the installation team gently start the water, check the appliance. Switch off the water heater immediately after leaving. When the warranty card is filled, we are looking for a marriage. We wait, drink tea, do business for 3-5 hours, then.
4. We check for leaks at the mounting nodes, from under the case. We remove the front shield, measure the insulation resistance of the heating element with a tester. "Dry" or ordinary, the value must be above 20 MΩ (without special equipment, the Chinese tester will show infinity). Having identified problems, call the manufacturer (not the dealer), check the normal value of the parameter.
5. There are no malfunctions - we turn on the device, according to the passport we look at the time to enter the mode. It just happened - we look to see if water has begun to drip from the bypass valve. If yes, the hardware is fine. Moisture may be absent in some cases. Then we measure the insulation resistance again.

During the first time, we carefully monitor storage water heaters. We check the insulation resistance regularly. Run-in time, the probability of failure is high. After a few weeks, the device will acclimatize, it will be possible to set aside the tester. A leak was detected - the heating element will not explode immediately. Indefinitely, more power will be consumed than expected. Then, finally, it bursts. You should not wait for a break, a decrease in insulation resistance has been detected - call the company's technical support service.

It is worth buying a water heater with a dry heating element. At least look at the work of curiosity. It is not necessary to take Ariston, be guided by the guarantee, promotions of stores. Remember, such proposals are more likely to try to push the marriage. Pay more attention to quality. Ignoring what has been said about blocking electrochemical corrosion, try to find a device with a magnesium anode - the tank needs protection! TP will say assembly is useless here ... in extreme cases, duplicate the question to the manufacturer before buying (mentioning the magnesium anode). How to be in time? The modern rhythm of life dictates - if you want to live, know how to insist!

Question-answer of choosing a water heater

• Buy a floor or wall-mounted water heater.

Buy an underfloor water heater. Safer. The exception is flow models that are not heavy.

• How to buy a water heater cheap.

Find great deals on promotions. Discounts reach 40%. Be prepared that the dealer will try to sell the marriage. Whatever you say, and no matter how you convince, first of all, stick to the scope of the guarantee. It will not be good to be left alone, clutching a broken water heater with grief for 8 rubles (the average monthly salary of a Russian from the outback).

• Does a water heater need a magnesium anode?

A storage water heater needs an anode, a flowing water heater is an overkill. If the dealer says that the spare part is not installed, because the “dry” heating element, the third or tenth, call the factory for clarification. They will say that buying an anode for a water heater will be an extra step - make sure that there are no copper parts upstream and downstream of the device: supply pipes, instantaneous water heaters, bushings, couplings.

• Where to get a water heater.

It's easier to order close to home. Buying a water heater is not an easy undertaking, unless you're Arnie in his prime. Instruments weigh 100 kg or more. Take care to carefully transport the equipment, free up space in advance. Take the dimensions, guided by the reference information of the Internet.

• How to hang a storage water heater.

To prevent the device from falling, solid anchors are needed. Not always the fasteners of the kit are suitable. For plastered walls, problem masonry, hollow bricks, it is reasonable to use chemical anchors. The main thing here is not to get to the neighbors when drilling, be afraid to pay for repairs. It's better to overdo it than get hit on the hump by a filled water heater, which is unsuccessfully suspended above the toilet. Ceramics will shatter.

• We tried to find Atlant water heaters on the Yandex market, unsuccessfully. What to do.

Do not try to buy an Atlant water heater there, because it is not on sale. Explore the official site. See faucets for installation in the bathroom sink. Flowing water heaters with a power of 2 kW. The shelves of the Yandex Market of aggregates are completely devoid of. Whether the omission of the moderators, the manufacturer's advertising policy, is hard to say.

• Where did the insulation resistance of 20 MΩ come from when checking the heating element.

Typical insulation resistance of current-carrying parts of household appliances, which is prescribed by the standards. The real value is greater, we do not pursue the goal of rewriting GOSTs by the forces of the VashTekhnik portal. Just gave the order of numbers indicative.

This will help you avoid mistakes. Remember, today you won’t always get a quality product for a promotion. Not every expensive thing is a model of durability. When buying a water heater, you need to rely on advice and your own discretion.
