In case of insufficient efficient operation of the local CHP or during the seasonal shutdown of hot water, a water heater will be an indispensable device in every house. Choose a device that will not only cope with its task, but also prove to be economically viable.

How to choose a water heater

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

What factors should be considered when choosing a water heater?

• Heater type. The storage water heater is equipped with a heat-insulated tank in which water is stored. An 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.
• A source for heating water. Gas boilers require less energy and are cheaper than electric ones, although at the time of purchase they may be more expensive. Indirect heating devices need to be connected to a separate heating boiler, which complicates the installation. There are also solar heating systems.
• Storage water heater capacity. To determine the capacity, consider the number of people in the family, shower and bath consumption, and the presence of water-consuming devices such as a washing machine and dishwasher. In order to warm up the water to the required temperature, the storage device will take some time. After the tank is used up, you will also have to wait until the next batch of hot water.
• The value of the flow of the passed water at the instantaneous water heater. The flow-through 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 draw-off point and you will not be able to take a shower if the kitchen is washing dishes at this time. Therefore, in a family of several people, it is wiser to provide a model adapted to 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. The flutes are more compact, they can be built directly under the sink. Models with very large tanks will require floor standing.
• Upper or lower water connection. Depending on the location of the water heater, a specific type of connection may be preferable. For example, if you want to build a heater into the cabinet under the kitchen sink, the top piping is more convenient.
• Ignition method. Automatic ignition will turn on the device when you open the tap. Piezoelectric or battery-powered ignition will require pressing a button to light the burner to heat up 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 to maintain a normal flow rate of the heated liquid.

Keep in mind that high power units will require a dedicated circuit breaker in the switchboard and sometimes a three-phase connection.

• Installation and connection of the device. Many types of boilers can be installed independently due to simple installation. Determine if the self-install heater is still under warranty. If not, consult a professional.

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 on the bottom of the tank during boiling. Although mineralization will shorten the life of the heating element, you should not overpay for the operation of this device.

The service life of a heating element is primarily determined by the hardness of the water. The higher the hardness, the more often the heater will need to be serviced.

• Mechanical or electronic control. Heaters with mechanical buttons provide limited settings, but electronic panels are not always responsive to wet finger pressure. Some models are supplied with a remote control.
• Digital screen. This detail is electronically controlled and displays the current water temperature. Some models allow you to set an economical flow rate and individual heating temperatures for each family member by a timer.
• Antibacterial tank lining. Rather, it is a marketing ploy for storage-type water heaters, since if water is stored for a long time in a tank 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.

Our specialists will contact the customer as soon as possible, name the preliminary cost of manufacturing the heaters, specify the required quantity, and also inform about the approximate timing of the work.

Consider the brands released today. We hope the review will be interesting, the time spent reading is useful. We recommend taking goods for the money, the market is devoid of outright 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 a little lame, let's make up for the lack.

Electric storage water heaters Ariston

Electric storage water heaters are standard in terms of volume. Models available in capacities 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 studded with silver ions. Know-how of the corporation, technology that inhibits the growth of harmful bacteria. Who does not know - water intake is carried out by the upper quarter, the bottom is considered a stagnation zone. These areas need silver ions. Is the innovation useful. Certainly! Each firm tries to creatively invent a fresh enamel composition, carefully guarding the secrets of research laboratories.

The problem of the Ariston firm is limited by the lack of advertising in Russia, the manufacturer presented the most of the models exhibited by the Yandex market. We do not recommend ignoring Ariston, although the official website of the company is mediocre in search convenience. According to the parameters of the Yandex market, it was determined: the company, having exposed 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 our readers to something else! The Ariston firm has presented excessively large-volume floor-standing electric water heaters. Such are good when you are afraid to get, mastering the toilet, on the hump with a weighty capacity. Let's say more, where there is enough space, put only a bulky floor-standing water heater. The American is given the top priority. The United States is rarely too lazy to scold 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 floor-standing water heaters, pay attention.

Gas storage water heaters Ariston

The Ariston company has shown 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, an elegant solution for apartments supplied with natural gas. Overburdening the low specific heat of combustion, the result is excellent. Americans equip individual cottages with units.

Ariston produces models 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 storehouse 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);
• outdoor execution;
• 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 faucets of a private house. It implies an intensive consumption, 30 kW is enough for 5-6 shower cabins in real time. We just explain - the proposed non-apartment option, semi-industrial equipment of a small hotel.

Consider the use of waste gases. Try assembling a dark infrared heat exchanger in your chimney. There would be an almost complete return of the energy generated by the combustion of the gas. That we will praise Ariston. The firm has in store for budget and professional solutions. If in dire need, take it without fear. Spare parts are on every corner, buying a thermostat for an Ariston water heater will not pose any problems, heating elements, magnesium anodes.

Water heaters Termeks

Termex boasts the fame of one of the best brands in Russia for a reason. Water heaters of the renowned manufacturer are suitable for Russian realities. Purposefully designed. The company avoids producing gas heaters, left happiness to the domestic brand Neva, switching to market research.

Termeks produce water heaters of the so-called indirect type. Boilers, in fact. The water is heated by an external boiler, built-in electric heating element. If the coil gives 1.5 kW, the heat exchanger overlaps the named value tenfold. We see a typical boiler of relatively small volume. Using a domestic boiler that produces water with 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 an inexpensive boiler.

Buy a horizontal water heater from Termeks. Sometimes convenient when installed under the dishwasher where nothing else can fit. Pay attention to the flow models of this manufacturer. You will see options even for two showers (or shower + sink). The necessary connectors for mounting are included in the design. Power reaches 8 kW, an atypically high figure. Buffalo quota will be pulled by a rare electric shield. We suppose a model for small hotels, where the rooms are devoid of individual showers. Those who wish will wash themselves in common booths.

We emphasize! The market did not provide analogs to flow models. Remember, wondering which brand to buy a water heater.

Water heaters Electrolux

Among the highlights of Swedish heaters, we see "dry" heating elements, avoided by Ariston. For fans of new technologies, a note: guaranteed protection against scale. However, there will still be a deposit of the magnesium anode. 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. Electrochemical corrosion chains are laid over long distances, the electrical resistance of water diluted with hardness salts is small.

Electrolux ceded the segment of storage gas water heaters to Ariston, but it came to grips with the columns. When making a search, limit your attention to cheap gas water heaters. Electrolux does everything wisely, take it without hesitation. Geysers of 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) shower rooms are enough. Master natural gas, you will probably be able to save money.

The gas water heater shows two troubles:

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

In the simplest models, the temperature is not controlled. The power has been calculated in advance, and this is not necessary.

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

A couple of numbers for thought. Water heaters will help to quantify:

1. 200 liters with a heating element power of 2 kW are heated for 8-9 hours, reaching a temperature of 70 degrees.
2. The water consumption for showering is over 3.5 liters per minute.
3. One shower procedure takes 15 liters of water from men and 25 liters from women.
4. For a satisfactory wash in the shower, an instantaneous water heater above 4 kW of power is needed.
5. A family couple is suitable for a storage water heater with a capacity of 50 liters, for a family with a child - over 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, which is not within the power of every Russian engineer.
7. You need to buy a thermostat for a water heater, try to take exactly the same one. Producers have variable maximum water temperatures. Compare Bosch, Ariston - make sure.

Consider the above information, the selection process will seem easy. Maybe decide to buy an aquarium water heater. However, more on that another time.

Where to start buying a water heater

The Internet is periodically supplemented by a myriad of angry articles claiming that the heater of this or that company has failed. Found one review regarding Termex. We claim the comments below are fabricated by competing firms, at least in part. Therefore, today we will 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 have forgotten the trivial wisdom.

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

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

Usually the company sets some conditions for warranty service. Every 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, the conditions are new each time. What to do if the tank cover was damaged during installation, the wall is rotten. Parodying the presenters 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 in life is doing according to the latter option. They show an eloquent photo of a "copper" heating element of steel color, complain. The authors are immediately asked three questions:

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

The heating element breaks off by overheating, if the insulation is broken, water penetrates inside, boils, increases in volume, looking for a way out. Inside the heating element, a nichrome wire (fechral) under 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 is the careless operation of a steel heating element without a magnesium anode. In the first case, at the launch stage, you perform a check.

According to the mind, the plant should control. Firstly, Russia, secondly, some products are damaged during transportation, and thirdly, they boo the 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 on site, it is connected to utilities.
2. Refill the tank with water, avoiding plugging the appliance. The valves of the installation composition of the equipment are unlocked.
3. Then you need to slowly open the bathroom (shower) mixer to let the air go down.
4. After a long hiss (determined by the volume of the tank), a thin stream of water will pour out.
5. Close the valve in the bathroom (shower).

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

The water heater is ready to work, avoid supplying electricity. It is suggested to be kept under pressure for 5 minutes or more. Perhaps, for several hours, the presence of microcracks will allow water to seep inside. In parallel, dial the support service of the company, find out the insulation resistance of the heating element. Usually 20-25 MOhm. We admit 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 heating element body, the second against any electrode (do not confuse it with a thermostat, ring the plug if in doubt). We observe infinity (20 megohms exceed the limits of a typical household appliance). Any other, even a very large number, should force you to 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 test 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 readings indicate: water got inside, 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 each separately. And you can turn it on together. As soon as the device works the mode, it turns off, unplug the cord from the outlet. After that we remove the front panel again and call it. The logic is this: the temperature has risen, the materials have changed their 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 TENA for the Termeks water heater once again. In this case, it would be nice to shoot the detected defects on film (video). The problem expressed by practitioners: the company forces a professional to pay for the installation of the device. Violation of the rule will void the warranty.

Harm of scale to the heating element of the water heater

Why did they immediately mention hard water. Found, confused by the web, an angry review raising the issue. A 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 turning on the water heater, the value of water hardness. Whistling, buzzing is heard, strange vibrations appear, accompanying 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 Termeks water heater means losing in advance. The magnesium anode does not protect against scale, prevents electrochemical corrosion.

Why do you need a magnesium anode for a water heater

The magnesium anode protects the steel from copper attack. Steel are made:

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

Steel heating element - without a magnesium anode, it will break in the presence of copper pipes, fittings, flowing water heaters upstream (and below). A chain of atom leakage is created, be ashamed to complain later, discuss biasedly which company is better to buy a water heater, because this one, you see, is bad.

What is check & relief valve

During the operation of the water heater, there is a constant cyclical expansion, compression of the tank. The thermal coefficient of expansion of water is an order of magnitude different from steel. We bleed the excess pressure using the bypass valve. In the absence of such, water will quickly destroy the protective coating of the tank (seams), and corrosion will begin. As a result, the tank will burst, and 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 correctly, the technique will work 99% of the time.

Shower water heater

We missed the methodology for assessing the scale build-up, there is no efficient simple method. Just do an inspection periodically. It is enough to control the situation throughout the year to gain useful experience for the region for the rest of your life. Further simplifies operation.

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, check the terms of warranty service. As a rule, installing such a simple technique does not cost outrageous money. Perhaps some manufacturers trust the client with the work process. Ask. Then follow the instructions, check the equipment according to the diagram, evaluate the result.

Select a water heater by parameters

Any reader of the portal VashTechnik needs power, water volume will be helped by 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, tap water usually flows with a temperature of 8 degrees Celsius. You can easily calculate the power of the heater needed for an apartment that wants to enjoy the benefits of civilization.

Use the counter to mark the amount of water consumed by one bath session, how long the process lasts. At the exit, you will get a displacement every minute. Using the figure, we find the power by the formula:

N \u003d 4200 x L x 42/60,

L is the water consumption per minute, expressed in liters.

Suppose we will wash 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. This will be a fairly strong shower jet, and the formula has been fed with strict initial conditions. If we take summer, the initial temperature sometimes reaches 15 degrees, some 45 degrees will be enough to wash. In this case, a third is subtracted from the difference. It turns out 4-5 kW, which is considered the minimum consumption for an instantaneous water heater.

Guided by the formulas given, the reader will calculate the required power at home. Also applies to storage water heaters. But the formula is changed 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 trusting dealers with unsubstantiated praise, personal preferences differ from 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, to be guided by the calculation instead of the assurances of the sellers.

Water heaters equipped with dry heating elements

It is not easy to choose which water heater to buy for an apartment, watching today's abundance lining the counters. We will help you with advice, we hope to avoid repetitions in the reviews - read each one! Anyone will have something 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 storage and flow-through, but on what type of energy the device will work, you need to think. There is no problem if the design documentation of the house provides for a built-in chimney that is pre-equipped at the construction stage. God ordered to switch, taking a water heater, to blue fuel.

First, what is a heating element. The abbreviation stands for - tubular heating element. It is incorrect to call dry heating element a set of letters. Typically, 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 the rolling stage, the tube goes through the smaller holes.

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

As a result, the probability of failure of a heater with a "dry" heating element is minimal, the device needs to be serviced less often. Scale, 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 assess the range of choices, we recommend visiting the Yandex Market. To select the required models, set in the parameters:

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

There will be hundreds of models, some of which you can buy with discounts. 8000 rubles for 80 liters of an excellent tank (you can buy an Atlantic water heater for 7300). Agree, inexpensive. Ordinary models cost the same. The advantage of the Yandex market: you can quickly find a device for a promotion.

Let's face it, we use similar methods ourselves, examine Eldorado, Vikimart, try options for exchanging old technology. Get 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 broken penny; not everyone can fix a water heater with their own hands. In case of self-discovery of a defect, the goods can be returned.
2. The conditions have been clarified - start bidding, negotiate delivery. Find out who will install the water heater, whether the event voids warranty rights. A vital case: the installers were unable to properly remove the locking bolts of the washing machine! Household appliances do not like barbaric treatment.
3. The water heater is installed, let a group of installers start the water gently, check the device. Switch off the water heater immediately after leaving. When the warranty card is full, we look for a marriage. We wait, drink tea, do business for 3-5 hours, then.
4. We check for leaks on the assemblies from under the case. We remove the face shield, measure the insulation resistance of the heating element with a tester. "Dry" or ordinary, the value should be above 20 megohms (without special equipment, the Chinese tester will show infinity). After identifying the problem, call the manufacturer (not the dealer) to 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 - let's see if water started dripping from the bypass valve. If so, the hardware is fine. In some cases, moisture may be absent. Then we measure the insulation resistance again.

During the first time, we closely monitor storage water heaters. We check the insulation resistance regularly. Running-in time, the probability of failures is high. After a few weeks, the device will acclimatize, you can put the tester aside. A leak was found - the heating element will not explode immediately. An indefinite time will consume more power than expected. Then, finally, it will burst. There is no need to wait for a rupture, a decrease in insulation resistance was found - call the company's technical support service.

It is worth buying a water heater with dry TEN. At least see the work of the curiosity. It is not necessary to take Ariston, be guided by the guarantee, store promotions. Remember, such proposals are more often trying to shove off 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 that there is no need for assembly here ... as a last resort, 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, be able to insist!

Question-answer of choosing a water heater

• To buy a floor or wall water heater.

You should buy a floor-standing water heater. Safer. An exception is flow models, which are not heavy.

• How to buy a water heater for cheap.

You will find profitable offers on promotions. Discounts reach 40%. Be prepared for the dealer to try to sell the marriage. Whatever you say, and no matter how you persuade, first of all, adhere to the warranty framework. It would 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 provinces).

• Does the water heater need a magnesium anode?

A storage water heater needs an anode, a flowing one is an excess. If the dealer says the spare part is not installed, because the heating element is “dry”, third to tenth, call the plant 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 and downstream from the device: supply pipes, flowing water heaters, bushings, couplings.

• Where to get a water heater.

Easier to order near home. Buying a water heater is not an easy undertaking, unless you are Arnie in his prime. The devices 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 on the Internet.

• How to hang a storage water heater.

To prevent the device from falling, solid anchors are needed. The kit fasteners are not always suitable. It is reasonable to use chemical anchors for plastered walls, problematic masonry, hollow bricks. The main thing here is not to get to the neighbors, while drilling, be afraid to pay for repairs. Better to overdo it than to get over the hump filled with a water heater, which is unsuccessfully suspended above the toilet. The pottery 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. Study the official website. You will see taps for installation in the bathroom sink. Instantaneous water heaters with a capacity of 2 kW. The shelves of the Yandex market of aggregates are completely devoid of. It is difficult to say whether this is an omission of the moderators, the advertising policy of the manufacturer.

• Where did the insulation resistance of 20 megohm 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 by the forces of the VashTechnik portal They just gave an approximate order of numbers.

The foregoing will help protect yourself from mistakes. Remember, today you will not always buy a high-quality product for a promotion. Not every expensive item is a model 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 for a long period. Russian manufacturer installs new, more advanced standards, and their design, compactness and cost are their obvious advantages. Most of the 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 tank for water heating 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. These 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.
