*Review of the best sites according to the editors. About the selection criteria. This material is subjective in nature, does not constitute advertising and does not serve as a purchase guide. Before purchasing, consultation with a specialist is required.

Hot water is an essential attribute for the normal functioning of a modern person. Many residents of apartment buildings use it, unaware of all the difficulties of heating. And only during interruptions in the water supply does the question of purchasing an autonomous heating device arise. Residents of private houses usually solve this problem at the construction stage, and then the water heater is serviced and replaced. What criteria should an ordinary consumer follow in order to choose a reliable device for heating water?

How to choose a pre-heater

1. Energy source. First of all, you should start from 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 assessed.
2. Type. The next important point will be the choice of water heater type. Storage 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 your house or apartment where you can hide a storage tank, then it is better to give preference to this type.
3. Heating element type. Electric boilers can use “wet” or “dry” heating elements. The boiler principle 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, even though it costs more. Its 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 affordability, consumers often choose enameled steel. Modern coating technologies involve the introduction of silver ions into the enamel layer, thereby simultaneously fighting corrosion and bacteria.
5. Weld. The weak point in tanks made of different materials is the welding seam. To prevent it from being destroyed during operation, anodic 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. It’s quite easy to decide on the shape of the tank. Rectangular designs look more compact, and models with a barrel-shaped body are cheaper. Recently, slim models have become popular. They have one side (diameter) smaller, which makes it easier to place the device in a cramped room.
7. Mounting method. Depending on 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 are wall-mounted, while industrial appliances are floor-mounted.
8. Control system. Each water heater has a control system. The simplest method is considered to be the mechanical one. It is practical and accessible. The disadvantage is that the water temperature is not completely accurate. Electronic control increases not only the comfort of operation, but also the cost of the device. Thanks to the display and touch buttons, you can specify the exact temperature range, and then monitor the readings of the device.
9. Additional functions. A number of additional functions are reflected in the price of the water heater. Overheating protection directly affects the safety level of the device. Using a timer, you can save a lot of money by setting it to work in night mode. The cooling rate of the water will depend on the thickness of the thermal insulation. In pursuit of compactness, it is important not to forget about this point.

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

Attention! This rating is subjective in nature, is not an advertisement and does not serve as a purchase guide. Before purchasing, consultation with a specialist is required.

If the local thermal power plant is not operating efficiently or during a seasonal shutdown of hot water, a water heater will be an indispensable device in every home. Choose a device that will not only cope with its task, but will also be cost-effective.

How to choose a water heater

There is no definite answer to which water heater you will need personally for your needs, since manufacturing companies offer devices whose designs are implemented on the same operating principles as those of competitors.

What factors should be considered when choosing a water heater?

• Heater type. The storage water heater is equipped with a thermally insulated tank in which water is stored. The instantaneous heater is more compact and provides hot water as needed. Such a device is more economical, but provides a limited flow per unit of time.
• Source for heating water. Gas boilers require less energy and are more budget-friendly than electric ones, although they may be more expensive at the time of purchase. Indirect heating devices need to be connected to a separate heating boiler, which complicates installation. Solar heating systems are also available.
• Storage water heater capacity. To determine capacity, consider the number of people in the family, shower and bath costs, and the presence of water-consuming appliances such as a washing machine and dishwasher. In order to heat the water to the required temperature, the storage device will take some time. Once the tank is used up, you will also have to wait for a new batch of hot water.
• The amount of flow of water passed through an instantaneous water heater. The flow device does not have a container for storing hot water. The efficiency of such a heater is determined by the number of liters per minute.

Please note that some instantaneous water heaters are designed for a single water outlet and you will not be able to take a shower if dishes are being washed in the kitchen at the same time. Therefore, in a family of several people, it is more reasonable to provide a model adapted for several water supply points.

• Place for installation. Storage water heaters will require dedicated space to be placed vertically on the wall or horizontally under the ceiling. Drains are more compact and can be built directly under the sink sink. Models with very large tanks will require floor mounting.
• Top or bottom water supply connection. Depending on the location of the water heater, a specific connection type may be preferable. For example, if you need to build a heater into a cabinet under the kitchen sink, top piping is more convenient.
• Ignition method. Automatic ignition will turn on the device when the tap is opened. Piezoelectric or battery-powered ignition will require pressing a button to light the burner to heat the gas boiler.
• Power. For a storage water heater, high power means a fast heating rate of the tank. In the case of an instantaneous water heater, this parameter is important for maintaining the normal flow rate of the heated liquid.

Keep in mind that high-power devices will require the installation of a dedicated circuit breaker in the distribution panel, and sometimes a three-phase connection.

• Installation and connection of the device. Many types of boilers can be installed independently due to their simple installation. Find out if the heater service warranty is still valid if you install it yourself. Otherwise, contact the professionals.

What details can you ignore when buying a water heater?

• Anti-scale function. Some manufacturers advertise models with reduced formation of mineral scale that forms at the bottom of the tank during boiling. Although mineralization shortens the life of the heating element, you should not overpay for the operation of this device.

The service life of the heating element is primarily determined by the hardness of the water. The higher the hardness, the more often the heater will require maintenance.

• Mechanical or electronic control. Heaters with mechanical buttons provide limited adjustments, but electronic panels are not always sensitive to pressure with wet fingers. Some models are equipped with a remote control.
• Digital screen. This part is accompanied by electronic control and displays the current water temperature. Some models allow you to set an economical flow mode and individual heating temperatures for each family member using a timer.
• Antibacterial internal coating of the tank. This is rather a marketing ploy for storage-type water heaters, since if water is stored in a tank for a long time without use, the liquid will bloom. Therefore, if the water heater is not used for a long time, it is recommended to drain the water from the tank.

Let's look at the brands produced today. We hope the review will be interesting, and the time spent reading will be useful for those lost. We recommend buying goods for the money, the market is devoid of outright outsiders, the latter have long been outlived by competition. We don’t set out to find a bad brand; we’ll take an excursion into what models the manufacturer produces. From the position described, we are going to answer the question of which brand of water heater is best to buy. Let's get started.

Ariston water heaters

Ariston sales account for the lion's share of the market. The official websites of the manufacturer are presented with 27 options. Mainly English speaking. In our opinion, the sorting is a little lame, let's make up for the deficiency.

Electric storage water heaters Ariston

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

• enamel;
• stainless steel;
• titanium.

It is clear that the latest line will be more expensive. Ariston enamel is dotted with silver ions. The corporation's know-how, technology that suppresses the growth of harmful bacteria. For those who don’t know, water is taken from the upper quarter; the bottom is considered a stagnation zone. Such areas need silver ions. Is the innovation useful? Undoubtedly! Each company is trying to creatively invent a fresh enamel composition, 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 on Yandex Market. We do not recommend ignoring Ariston, although the company’s official website is mediocre in terms of ease of search. According to the Yandex Market parameters, it was determined that the company, having exhibited 200 models, did not present a single one with a dry heating element. Is it good or bad. We conclude: the manufacturer is self-confident: he avoids introducing something new. Trade is in dispute - priority is given to conservative policies.

We wanted to draw the readers' attention to something different! The Ariston company has excessively presented large-volume floor-mounted electric water heaters. These are good when you are afraid of getting hit on the hump with a heavy container while mastering the toilet. Let's say more, where there is enough space, install a bulky water heater of a floor-mounted design only. Americans give security a leading role. The United States is rarely too lazy to scold it out of envy; the developed world has heard a lot about the technology of the New World. Let's leave politics. Ariston has several lines of underfloor water heaters, please note.

Gas storage water heaters Ariston

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

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. Moreover, the winner is unknown. Let's say more, some people specifically replenish the heating circuit with a reserve in the form of a large container. 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);
• floor version;
• tank 275 liters;
• weekly cycle programmer.

An input pressure of 0.5 – 8 atmospheres will allow the device to be used everywhere. Including heating circuit. Is it possible to do this? Check with the company. The price is steep (200,000 rubles), the quality speaks for itself. The water heater can supply the faucets of a private home. This implies intensive consumption, 30 kW is enough for 5–6 shower cabins in real time. Let’s just explain – the proposed option is not an apartment option, but semi-industrial equipment for a small hotel.

Consider the use of exhaust gases. Try to assemble a kind of dark infrared heat exchanger in the chimney. The result would be almost complete release of the energy generated by the combustion of gas. Let's praise Ariston. The company has budget and professional solutions in stock. If you absolutely need it, take it without fear. Spare parts are available on every corner; buying a thermostat for an Ariston water heater will not be any problem, heating elements, magnesium anodes.

Termex water heaters

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

Termex produces water heaters of the so-called indirect type. Actually boilers. The water is heated by an external boiler with a built-in electric heating element. If the spiral produces 1.5 kW, the heat exchanger covers the said value tenfold. 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 the 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 convenient when installing under a dishwasher sink, 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. The power reaches 8 kW, an atypically high figure. The buffalo quota will be covered by a rare electrical panel. We believe this is a model for small hotels where rooms do not have individual showers. Those who wish can wash in the common cabins.

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

Electrolux water heaters

Among the highlights of Swedish heaters we see “dry” heating elements, avoided by Ariston. Fans of new technologies take note: guaranteed protection against scale. However, there will still be sediment from the magnesium anode. If you take a water heater without protection, you risk the tank body. Networks often contain copper parts; a neighbor’s elementary instantaneous water heater will pose a threat to the equipment. Electrochemical corrosion chains are laid over long distances; the electrical resistance of water diluted with hardness salts is low.

Electrolux lost out to Ariston in the segment of storage gas water heaters, but was closely involved in columns. When searching, limit your attention to cheap gas water heaters. Electrolux does everything wisely, take it without hesitation. Manufacturers' geysers have at least three degrees of protection.

For 3,500 rubles you will find a faithful assistant with a power of 20 kW. Two (even three) showers are enough. Master natural gas, you will certainly be able to save money.

The geyser shows two problems:

1. The pilot light burns continuously and irritates zealous owners. Some modern models have electronic ignition and no ignition group. However, the water heater is quite expensive.
2. The water will begin to warm up gradually. First, the flow must gain strength for the sensor to operate. Therefore, you will have to wait time. Not everyone will like this state of affairs.

In the simplest models, the temperature is not controlled. The power is pre-calculated and is not necessary.

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

A couple of numbers to think about. They will help to 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 for men, 25 for women.
4. For satisfactory cleaning in the shower you need an instantaneous water heater with a power higher than 4 kW.
5. A storage water heater with a capacity of 50 liters is suitable for a married couple, and above 80 liters for a family with a child.
6. Try to avoid hanging water heaters on the walls yourself. It is necessary to more accurately calculate the strength of the wall, which not every Russian engineer can do.
7. You need to buy a thermostat for your water heater, try to get exactly the same one. Manufacturers' maximum water temperatures vary. Compare Bosch, Ariston - see for yourself.

Consider the information above, the selection process will seem easy. Perhaps you decide to buy a water heater for your aquarium. However, more on 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 this or that company has failed. We found one review regarding Termex. We submit that the comments below are fabricated, at least in part, by competing firms. Therefore, today we’ll talk about how to properly start using a water heater, so as not to blame the manufacturer later. People sometimes come across defects, more often the buyer lacks knowledge and the ability to properly operate household appliances. Which company to buy a water heater is the tenth thing if you have forgotten the trivial wisdom.

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

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

Usually the company sets certain conditions for warranty service. Every self-respecting manufacturer will provide a toll-free phone number through its 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, the conditions are new every time. What to do if during installation the tank coating was damaged or the wall was rotten. We parody the hosts of Who Wants to Be a Millionaire:

• Bite your elbows.
• Blame the manufacturer.
• Flood the forums with angry reviews.
• Recognize your mistakes and do the right thing in the future.

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 and complain. The authors are immediately asked three questions:

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

The heating element bursts due to 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) with a voltage of 230 V. Water begins to rapidly disintegrate, forming hydrogen and oxygen, increasing the pressure. How did the liquid get inside?

Heating elements for water heaters

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

In mind, the plant should be controlled. Firstly, Russia, secondly, some products are damaged during transportation, thirdly, a mountain of raki boos. In any case, check the insulation resistance of the heating element in a tank filled with water. See how to do it:

1. The water heater is installed locally and connected to utilities.
2. Avoiding plugging in the appliance, fill the tank with water. The valves of the installation equipment of the equipment are unlocked.
3. Then you need to slowly open the bathroom (shower) faucet to allow air to escape.
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 a water heater heating element under operating conditions

The water heater is ready to operate, avoid supplying electricity. It is suggested to maintain pressure for 5 minutes or longer. Perhaps for several hours, the presence of microcracks will allow water to seep inside. At the same time, dial the company’s support service and find out the insulation resistance of the heating element. Typically 20–25 MOhm. We admit that the figure may differ slightly. We take the 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 against any electrode (do not confuse it with the thermostat, ring with the plug if in doubt). We observe infinity (20 MΩ exceeds the limits of a typical household appliance). Any other number, even a very large one, should make you ask a question to the support service or a specialized forum.

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

If you notice low insulation resistance, immediately call the company’s specialists and replace the device according to the warranty.

Small readings indicate that water has gotten inside and the case smells 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 and turns off, unplug the cord from the outlet. Then we remove the front panel again and call. The logic is this: the temperature has risen, the materials have changed geometric dimensions, which means we will check the tightness. Next we proceed according to the old scheme.

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

Damage caused by scale to water heater heating elements

Why did they immediately mention hard water? We found, tangled in the net, an angry review addressing the issue. The phrase slipped through: cleaning is carried out once a year. Where did the fixed term come from? Instructions? The Chinese copied from the left equipment. The frequency is determined by the frequency of switching on the water heater and the amount of water hardness. If you hear a whistle, a buzz, or strange vibrations appear that accompany the operation of the device, it’s time to drain the water and carry out extraordinary maintenance. Laziness! Then there is no point in complaining later that buying a Termex water heater means losing in advance. The magnesium anode does not protect against scale and prevents electrochemical corrosion.

Why do you need a magnesium anode for a water heater?

The magnesium anode protects the steel from the aggression of copper. Made from steel:

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

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

What is a check & bypass valve

During 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 steel. We release excess pressure using a bypass valve. In the absence of this, water will quickly destroy the protective coating of the tank (seams), and corrosion will begin. As a result, the tank will rupture and a flood will begin. To prevent this from happening, read the instructions carefully.

Which water heater manufacturer should you prefer?

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

Shower water heater

We missed a method for assessing scale build-up; there is no practical simple method. Just check periodically. It is enough to monitor the situation for a year to gain useful experience for the region for the rest of your life. It simplifies operation in the future.

There is no need to sit and think about which company to buy a storage water heater. Just choose a product according to the parameters, before purchasing, call the manufacturer to clarify the terms of warranty service. As a rule, installing such simple equipment does not cost an exorbitant amount of money. Perhaps some manufacturers trust the client with the work process. Ask. Then follow the instructions, check the equipment according to the diagram provided, and evaluate the result.

Select a water heater by parameters

Any reader of the VashTekhnik portal will be able to find out the power requirements and water volume using a simple calculation. It is known: 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 from the tap usually flows at a temperature of 8 degrees Celsius. You can easily calculate the heater power required for an apartment that plans to enjoy the benefits of civilization.

Use a meter to record the amount of water consumed in one bath and how long the process lasts. At the exit you will receive a displacement per minute. Using the figure, we find the power using the formula:

N = 4200 x L x 42 / 60,

L – water consumption every minute, expressed in liters.

Suppose we wash with water at a temperature of 50 degrees Celsius, the difference with the riser will be 42 degrees. A weak pressure is created at 3 liters per minute. Based on the given conditions, we obtain a power of 8.8 kW. This will be a fairly strong shower jet, and the formula was 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. The result is 4–5 kW, which is considered the minimum consumption for an instantaneous water heater.

Guided by the given formulas, the reader will calculate the required power of the house. This also applies to storage water heaters. But the formula is changed to find the time it takes for the tank to reach condition. Off the top of my head, 8 – 9 hours per 200 liters. You can get a different figure depending on your needs and initial data. It is better than to believe dealers who unfoundedly praise the product; personal preferences differ from the standards. Having set the initial conditions, buy an electric water heater exactly the one you need. Please note that in a couple of days it is easy to determine a family’s need for water, guided by calculations instead of the assurances of sellers.

Water heaters equipped with a dry heating element

It is not easy to choose which water heater to buy for your apartment, observing today's abundance lining the shelves. We will help you with advice, we hope to avoid repetition in reviews - everyone should read! In each there will be something new, hitherto unknown. Not surprising considering how many varieties there are in the store. Let’s say right away that between storage and flow-through systems, residents choose the first option in 90% of cases, but you need to think about what type of energy the device will operate on. There is no problem if the design documentation of the house provides for a built-in chimney that is pre-equipped during the construction stage. God ordered us to switch, taking the water heater, to blue fuel.

Firstly, what is a heating element. The abbreviation stands for tubular heating element. It is incorrect to call a dry heating element a set of letters. Typically, a tubular heating element is manufactured as follows:

1. A nichrome thread is taken and placed in the center of a metal (steel, copper) tube.
2. Heat-resistant powder is poured inside.
3. Then comes the rolling stage, the tube passes through smaller holes.

As a result, the heating element takes shape. Nichrome separated from the shell by an insulating layer of powder. The ceramic coat is compressed tightly, the tube is cut into pieces from which a spiral is bent. Standard option. When making 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 likelihood of a heater with a “dry” heating element failing is minimal, and the device needs to be serviced less frequently. Scale and electrochemical corrosion are the main enemies of heating elements; 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 choices, we recommend visiting Yandex Market. To select the desired models, set in the parameters:

1. Water heater type – storage.
2. Heating method: electric.
3. Dry heating element - yes.

Hundreds of models will appear, some of which you can buy at discounted promotions. 8000 rubles for 80 liters of an excellent tank (you can buy an Atlantic water heater for 7300). Agree, it's inexpensive. Regular models cost the same. The advantage of Yandex Market: you can quickly find a device on sale.

Let’s face it, we use similar methods ourselves, we look around Eldorado, Wikimart, we try options for exchanging old equipment. Buy a water heater for free. The thing will still be good, you need to take the trouble to check the purchase correctly before installation.

1. First, be concerned 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. If you discover a defect on your own, the product can be returned.
2. The conditions have been clarified - start bidding, negotiate delivery. Find out who will install the water heater and whether the event voids warranty rights. A real-life case: the installers were unable to remove the locking bolts of the washing machine correctly! Household appliances do not like barbaric treatment.
3. The water heater is installed, let a group of installers carefully turn on the water and check the device. Immediately after leaving, turn off the water heater. When the warranty card is filled out, we look for a defect. We wait, drink tea, do business for 3-5 hours, then.
4. We check for leaks on the mounting units and from under the housing. We remove the face shield and measure the insulation resistance of the heating element with a tester. “Dry” or ordinary, the value should be above 20 MOhm (without special equipment, the Chinese tester will show infinity). If you identify any problems, call the manufacturer (not the dealer) and check the normal value of the parameter.
5. There are no malfunctions - turn on the device, use the passport to check the time it takes to reach the mode. It just happened - let's see if water starts dripping 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 regularly check the insulation resistance. Break-in time, the probability of failures is high. After a few weeks, the device will acclimatize and you can put the tester away. If a leak is detected, the heating element will not explode immediately. Indefinitely it will consume more power than it should. Then, finally, it will burst. You should not wait for a break; a decrease in insulation resistance is detected - call the company’s technical support service.

It’s worth buying a water heater with a dry heating element. At least look at the work of the curiosity. You don’t have to buy Ariston, rely on the guarantee and store promotions. Remember, with such proposals they often try to push the marriage away. Pay increased 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... as a last resort, ask the manufacturer before purchasing (mentioning the magnesium anode). How to make it in time? The modern rhythm of life dictates - if you want to live, be able to insist!

Questions and answers about choosing a water heater

• Buy a floor or wall water heater.

You should buy a floor-mounted water heater. Safer. The exception is flow-through models, which are not heavy.

• How to buy a water heater cheaply.

You will find great deals on promotions. Discounts reach 40%. Be prepared that the dealer will try to sell the defect. Whatever he says, and no matter how he convinces, first of all, adhere to the framework of the guarantee. It won’t be good to be left alone, clutching a broken water heater in grief for thousands of people 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 flow-through water heater is an overkill. If the dealer says the spare part is not installed because the heating element is “dry”, third to tenth, call the factory to clarify. 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 or 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 no easy feat unless you're Arnie in his prime. Devices weigh 100 kg or more. Take care to transport the equipment carefully and make room in advance. Take the dimensions based on reference information on the Internet.

• How to hang a storage water heater.

To prevent the device from falling, you need high-quality anchors. The kit's fasteners are not always suitable. For plastered walls, problematic masonry, and hollow bricks, it is wise to use chemical anchors. The main thing here is not to get into the hands of your neighbors when doing drilling; be afraid to pay for repairs. It’s better to overdo it than to get hit on the hump by a filled water heater that is poorly hung above the toilet. The ceramics will shatter into pieces.

• We tried to find Atlant water heaters on Yandex Market, but were unsuccessful. What to do.

Do not try to buy an Atlant water heater there, because it is not on sale. Check out the official website. You will see taps for installation in the bathroom sink. Instantaneous water heaters with a capacity of 2 kW. The Yandex Market shelves are completely devoid of units. It is difficult to say whether this is an omission of the moderators or an advertising policy of the manufacturer.

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

Typical insulation resistance of current-carrying parts of household appliances, which is prescribed by standards. The real value is greater; we do not pursue the goal of rewriting GOSTs using the VashTekhnik portal. They just gave an approximate order of numbers.

The above will help you avoid mistakes. Remember, today you won’t always get a quality product at a promotion. Not every expensive item is an example of durability. When buying a water heater, you need to rely on advice and your own discretion.

Russia is one of the leaders in the production of technological equipment for heating water and maintaining its temperature over a long period. The Russian manufacturer installs new, more advanced 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 made of stainless alloy steel.

Classic traditional Russian water heater has the following features and benefits:

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

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