How to choose an electric storage water heater: device features and classification

The main feature of a storage water heater is its efficiency compared to flow-type models. After all, they can maintain the desired effect. required amount time. To choose the models of the best electric storage water heaters, you need to understand the features of the design and its device. Such devices allow you to get heated water for long periods of time. When cooling water and its consumption, heating is automatically performed. This process does not require human intervention.


Such equipment can be used in apartments, office buildings, cottages, cottages and workshops.

The tank is made of stainless steel or copper. To prevent corrosion processes, special coating components are used. Heating elements can be of two types: dry and tubular. Also in water heaters there is a protection and control mechanism. In the classic version, a thermostat is used. An auxiliary thermostat is used to control the operation. A control board is also added. With it, you can set the appropriate heating temperature. All components of the equipment are placed in the case. Important Features given part is heat insulation and thickness.

Any heater has tubes inside that distribute hot and cold liquid. Most often, water enters from below, and then it is distributed using a jet divider throughout the tank.

How to choose the right equipment you can see in the video:

The principle of operation of electric water heaters: types of storage device

Accumulative electric have a principle of operation, which is based on heating the liquid to the desired performance. At the same time, cooled, and then under pressure, it exits and hot water. average temperature similar structures about 60-65 degrees. The heating of the liquid depends on the power of the heating element and the volume of equipment.

After connection, a heated coolant enters the heat exchanger, which cools down, and then warms up the liquid filling the tank. Circulation occurs when water is heated, which rises from the very bottom of the tank. Warm water appears in the upper part of the appliance immediately after heating. As water is consumed, the lower part of the tank is filled with it again. The heating is periodically turned off, and the appliance retains heat.


Models of storage electric water heaters for washing are horizontal and vertical type. In horizontal models, cold and hot water are mixed, so the required temperature is adjusted. In horizontal equipment, the tubular heater is located in the side part, which slows down the heating of the liquid.

AT vertical design heating is faster, which helps. The heating element is located at the bottom of the device. In this case, the power can vary from 1.3 to 6 kW. In some models, a special power adjustment is provided for a more economical distribution of electrical energy. In different models there can be tanks with a capacity of 10 to 400 liters. Many designs include a thermostat.

Note! The power rating of the heating element varies between 1.5-2.5 kW. Models can work not only in heating mode, but also in standby mode.

Types of heating elements: characteristics of dry from wet version

You can always buy an inexpensive electric water heater accumulative type. To do this, it is worth analyzing different models and their characteristics. Heaters in boilers are called heating elements. These mechanisms are of two types:

  • tubular version is a tube of metal, inside which is placed a mechanism with high electrical resistance. Dielectric sand is used as an insulator, which is distributed inside the device;

  • also have dry water heater designs. In this case, the heating element is placed in a certain flask, and the space inside it is filled with quartz sand or oil. Such a mechanism is characterized by low heat loss and better electrical safety.

In addition to the features of the device, it is important to consider the length and power of the heater. The higher the area of ​​the part, the better the heat transfer and the less scale accumulates.

Dry heater has the following features:

  • ceramics are inert, which excludes interaction with salts;
  • such a heating element, unlike the standard one, has larger area surfaces;
  • the passivity of ceramics contributes to the extension of the service life.

Advantages and disadvantages of storage equipment

Consider the nuances and characteristics of a storage electric water heater 10 liters for washing.

Here are the benefits worth noting:

  • small power rating. It does not require additional wiring;
  • multiple points can be used;
  • prostate in use;
  • can be installed at a certain distance from the water source;
  • To obtain the required temperature, a mixer is used, which is included in the kit.

There are also some disadvantages:

  • when installing, it is necessary to take into account the parameters;
  • to use the water from the new set, you need to wait a little.

A thermostat is required for proper functioning. It is used to regulate the temperature. Also the boiler has special protection against an overheat. As soon as the temperature reaches the red mark, the device turns off.

Equipment of 10 liters is suitable for washing dishes and cleaning. And for it will be necessary to purchase a more capacious tank.

How to choose water heaters for a summer residence

When choosing a water heater, you should decide where it will be installed and how often it is planned to be used. It is better to stay on small-sized models. For a country option, the volume of the tank does not have to be large. You can consider the design of a flat storage electric water heater 10 liters. Round and cylindrical devices take up a lot of space. But it should be borne in mind that flat models have small heat-saving qualities. This option is justified for infrequent use, as it takes up little space and fits well into small niches or cabinets.


Flat water heaters have a depth in the range of 23-28 cm. At the same time, the device quickly heats up the water. Also, some models have special dividers that can regulate the mixing of water of different temperatures.

It is important to take into account some of the disadvantages of flat devices. They have a shorter lifespan. In addition, the design assumes the presence of two heating elements, the installation of which increases the number of connections. The thermal insulation layer is not as thick as in standard designs.


To choose the right design, you must consider the following parameters:

  • the volume of the tank depends on the number of people who will use it, as well as on the required volume of water;
  • the volume of the inner coating can be made of stainless steel or enamel;
  • the power indicator affects the rate of water heating;
  • dimensions and type of fastening;
  • manufacturer's choice.

It should be borne in mind that during operation, any heaters are subjected to destructive effects from aggressive components, sudden changes in temperature and high pressure.

Note! At the time of buying storage device, it is necessary to find out from the consultants whether the equipment has a special anti-corrosion coating.

How to choose the volume of the tank: how the number of people and needs affect

The choice of a water heater with a tank depends on many parameters. It is important that the design meets all needs and is also an economical solution. Minimum size tank -10 liters, and the maximum 150.

You can choose from the following designs:

  • a capacity of 10 liters is enough for household needs, such as washing dishes and for taking a shower by one person. But such a device warms up quickly, and also consumes a small amount of electricity;
  • for two people, a 30 liter model is suitable, but you will need to wait a bit until the container warms up. To fill the bath of this volume is not enough, since it will take several hours to fill;
  • the volume of 50 liters is suitable for the needs of a small family. These are the most popular models;
  • with an 80 liter electric water heater tank, you can even take a bath. At the same time, this volume is not enough for a spacious jacuzzi;
  • products from 100 liters are suitable for large families. But such devices have significant weight and large dimensions. And for the installation of installations of 150 liters, it is worth checking whether they can withstand bearing structures such a weight.

Features of choice by power level

In all electric boilers for heating water of the storage type, there is 1 or a pair of heating elements. And these details may be different options power. In small tanks, 1 heating element is installed. At the same time, its power is 1 kW.

And electric storage water heaters of 50 liters are equipped with a mechanism with a value of 1.5 kW. Models with a capacity of approximately 100 liters are equipped with devices with values ​​​​of 2-2.5 kW.

Helpful information! Over time, various impurities contribute to the contamination of heating parts. To prevent breakdowns, it is recommended to clean the heating element from time to time. It is better to do this at least once a year.


The nuances of choosing the type of control

The electronic control method is known to be particularly advantageous. He has wonderful decorative properties and ease of use. At the same time, the price of an electric flat water heater of 30 liters of storage type can be several times higher than that of a device with mechanical settings.

With electric control, the desired indicators are set once, and then they do not need to be adjusted every day. Remember that the failure of at least one element can lead to the failure of the entire equipment.


Note! It is worth choosing electric models with caution if you have power outages and frequent power surges. Such phenomena can lead to equipment failure.

What are the advantages of anti-corrosion protection

Modern models have a special protective layer that prevents corrosion and damage to the structure.

Tanks can be:

  • stainless;
  • titanium;
  • enamelled.

The surfaces inside the tanks come into regular contact with the liquid, causing rust to form. Titanium sputtering or glass porcelain is used as a coating. The glass-ceramic version does not tolerate temperature fluctuations well, which causes cracks.

Which brand of storage water heater is better

Help to choose best option electric storage water heater reviews of different consumers. Such options can be attributed to safe equipment. But such structures are characterized by large weight and significant dimensions. Many manufacturers produce cylindrical units. Some devices have both vertical and horizontal mounting types. For comfortable installation, special additional fasteners, such as brackets, are used. The structures are fixed with dowels and studs. It is best to install on load-bearing walls that can support the weight of the devices.


When choosing a suitable design, you need to consider some interesting facts:

  • to warm up 200 liters at a power of 2 kW, it will take about 9 hours;
  • 3.5 liters are consumed per minute;
  • the shower procedure takes 15 liters of water from men and 25 from women;
  • married couple suitable option- 50 liters, and for a family with a child - 80 liters;

A water heater is a device used to heat water in a water supply system. The need to install a water heater is due to frequent problems with the supply of hot water from utilities or to provide hot water for a country house with autonomous communications.

When choosing the type of heater for a novice user, first of all, it is necessary to build on the conditions of its use. For private houses, the living area in which is disproportionately larger than in standard apartments, manufacturers (and experts) recommend purchasing storage boilers.

But flow heaters are best purchased for placement in apartments. They use a powerful copper heating element, which manages to heat the water as it flows through an isolated circuit. In this unpretentious way, you can get huge volumes of hot water. Another advantage of instantaneous water heaters is their compactness and the possibility of placing on the wall or in a special cabinet, which is very important in conditions of limited space.

Unfortunately, such installations are not without drawbacks. Firstly, the high power of the heating element implies a large consumption of electricity. It's one thing when we heat one draw-off point in a small apartment. Another thing is when it is necessary to provide several points with hot water. In this case, the water simply will not have time to heat up, but if you choose a powerful water heater, the electricity costs will definitely not please the owner of the house.

Today, many companies are engaged in the production and sale of instantaneous water heaters and indirect heating boilers, which are very popular among the mass consumer. However, not all models of the famous series have the right to be called the best. After carefully researching the market, we have selected for you the 12 best water heaters, marked good reviews ordinary users and authoritative experts. The following criteria were taken as the basis for the rating:

  • popularity of the manufacturer and model line of heating installations;
  • reliability parameters and performance characteristics;
  • vastness of functionality, abundance of protection circuits;
  • the presence of design features;
  • price match the overall build quality.

The best manufacturers of water heaters for the home

  • The largest range of water heaters is offered by the Italian company Ariston. It produces more than 300 models of both storage and instantaneous water heaters. The main advantages of their models are power, strict design, compact and easy to install.
  • Another Italian brand "Thermex" is famous for producing some of the most affordable water heaters. Their models are famous for their good design, economy and the best value for money. It is not for nothing that Thermex water heaters are one of the best-selling in Russia.
  • Timberk is a very famous Swedish manufacturer climate technology. The company's production bases are located not only in Europe, but also in China, Russia, South Korea and other countries. Timberk water heaters are, first of all, quality (case materials), performance and reliability. But the price is far from the lowest on the market.
  • The German brand "AEG" produces some of the most reliable and modern water heaters. The degree of protection against water they have one of the highest among competitors. Also, AEG water heaters stand out for their compactness, very light weight and low power consumption. But, you will have to pay well for the quality, so not many consumers will like the price.

The best electric instantaneous water heaters

Electric water heaters are the most common, as they can be installed anywhere where there is electricity. In view of the problems with connecting gas in remote communities, electric heaters are, in fact, the only option for homeowners. In maintenance, electric models are much simpler than gas ones, but the payment for electricity is higher than for gas.

It is worth considering another important point. Low-power water heaters are easy to install - they only need to be plugged into an outlet. But when connecting a device with a power of more than 5 kW, a separate electrical wiring and installation of a fuse are required.

5 Atmor Basic 5

Cheapest water heater Best heating efficiency
Country: Israel
Average price: 2,138 rubles.
Rating (2019): 4.5

With all the skepticism of consumers who somehow came across the products of this company, we simply could not get past one model. Atmor Basic 5 is the cheapest and at the same time the most productive (among small) instantaneous water heaters for houses and apartments. With a power consumption of 5 kW, it is able to heat up to 3 liters of water every minute, leaving a direct competitor from Electrolux out of work.

But, despite such "peppy" operational parameters, there is a certain range of nuances regarding the parameters of reliability and ergonomics. Firstly, Atmor Basic 5 lacks everything that can be missing on the front part - only the power switch is placed on it. Secondly, even with the provided two-level protection (against turning on without water and overheating), there are no guarantees of its long work. However, reviews of consumers who still ventured to purchase this heater indicate the opposite.

4 Stiebel Eltron DHC-E 12

The best indicator of reliability
Country: Germany
Average price: 31,200 rubles.
Rating (2019): 4.7

Stiebel Eltron DHC-E 12, although one of the most expensive instantaneous water heaters on the market, shows outstanding results in the reliability component. Made in Germany, it fully meets the expectations of consumers, which the latter are not averse to writing about in numerous reviews.

It is worth saying that DHC-E 12 is not the most powerful model in the series, and certainly not the most productive. 10 kW power of a copper heating element allows you to get up to 5 liters per minute of water with a temperature of at least 60 ° C. It is also noteworthy that the pressure in the installation allows you to connect several points of water intake. The heater is controlled mechanically, has a built-in thermometer, display and temperature limiter. The only truly significant drawback of the Stiebel Eltron DHC-E 12 is the level of cost. For the same money, consumers can buy a washing machine, a good refrigerator or a fully functional laptop. This is the real value of superior quality.

3 AEG RMC 75


Country: Germany
Average price: 15,100 rubles.
Rating (2019): 4.7

AEG RMC 75 is an electric instantaneous water heater from the industrial giant AEG is considered one of the most reliable on the market.

In positive reviews, buyers note ease of use and reliability in operation - this is a proprietary feature of Bosch. The disadvantages include factory defects on some models and the water heater body that is not resistant to corrosion. When buying, pay attention Special attention on the condition of the heating elements and in no case start the device without water - this can lead to the burnout of the heat exchanger. Despite not the lowest cost, worthy option for purchase.

The best indirect heating boilers

Indirect heating boilers use the energy generated by a heating boiler or other similar devices. A special coil or tank is placed inside the boiler. Due to the built-in circulation pump, the coolant constantly circulates in the tank, which serves as a source of water heating in the boiler. The main advantages of such devices are increased efficiency (in fact, the boiler itself does not consume anything), good thermal insulation, unpretentiousness (does not require constant attention), safety and long service life (up to 60 years).

The boiler is installed next to the heating boiler and heating, as a rule, occurs only when the heating is turned on. This is the main disadvantage of such devices. However, with proper installation of the heating system, this disadvantage can be avoided.

1 Gorenje GV 120

The best ratio of price and quality
Country: Slovenia
Average price: 21,100 rubles.
Rating (2019): 4.7

The first place in the ranking is Gorenje GV 120, one of the most affordable storage boilers for indirect heating. Despite the low cost, the device is equipped with all protection systems, including overheating protection, a check valve and a safety valve. There is a thermometer, indication of heating and inclusion. The boiler can serve several points of water intake, which is convenient for the home. We note a good tank capacity of 120 liters. and a stainless steel heat exchanger with high corrosion resistance.

According to numerous user reviews, the device quickly heats water (no more than 20 minutes), has a built-in magnetic anode. Also, many appreciate the five-year warranty on the tank and, in general, are very affordable price. Cons Gorenje GV 120: heavy weight and unfinished instructions.

Today, boilers are gaining more and more popularity among users. These sources of hot water supply help to live comfortably all year round, regardless of the schedule of heating networks. In the leading positions are precisely those devices that can accumulate and retain heat. This makes you think: which brand of storage water heater is best for your home?

Storage water heater device

Before talking about the proposals of specific brands, you should decide on the requirements that such equipment must withstand. Each of them is important:

  • volume;
  • power;
  • type of heater;
  • fastening type;
  • tank cover;
  • availability of options.

Capacity options

To deal with the volume, you need to know for what purposes the device is purchased. If only for washing dishes, then a “baby” of 15 liters will be enough. However, users are usually not content with little, and therefore good boiler should involve taking a shower and even a bath. For such purposes, a capacity of 100-120 liters will be enough - the water heater will successfully meet the needs of a family of three (the hot volume will also be diluted with cold water).

How to understand how much volume is needed for your family? Usually to apartments they buy boilers with a capacity of 80 to 100 liters (the small dimensions of the bathroom and kitchen simply won’t allow more). In the cottage such a restriction is removed - here it is really possible to allocate space even for a 200-liter tank.

Power and heater

The possibilities of the internal reserve are closely related to the power of the boiler. Depending on the volume indicators, one or two heating elements are used in the unit. For a small tank of 15 liters, a power of 1 kW will be enough, 30-50 liters already increase consumption to 1.5 kW, and in the case of large boilers from 80 liters and above, a heating element with a range of 2 to 2.5 kW is activated.

To the question of heating element: in its classical form it will be made of a copper tube, inside of which there is a conductive nichrome thread. This type of heater is conventionally called " wet» due to the fact that it works directly in the water. Such a service is fraught with consequences in the form of scale growing on the element.

To prevent the part from failing, it will need to be cleaned once a year.

"Wet" water heater heater

Recent innovations in this area include "dry" heater: when the heating part is placed in a special flask, which will come into contact with water, heating it. Such a solution turns out to be much safer and more reliable, but it will also cost more.

"Dry" heating element of the water heater

Even more impressive figures of the amounts will be at the aggregates with two heaters: such devices will heat the water much faster. Having reached the set temperature, one of these two parts (usually with a power of 2.5 and 1 kW) is turned off - this is how it is included in the program.

Reliable fastening

We figured out the main criteria, now it’s worth considering where the device will hang. For installation, it plays a big role, vertically or horizontally, this technique will hang on the wall. It all depends on the specific model: flat options are placed horizontally. Usually cumulative. electric boiler similar to a cylinder or a rectangular parallelepiped.

This device is attached with mounting brackets on dowels in the wall surface. It is desirable that it be a carrier, but if this is not the case, then for greater reliability, a through stud should be installed - after all, sometimes you will have to withstand more than a centner of weight.

Which water heater to choose - a traditional cylinder or an ultra-modern and air-conditioning device? Better one that will fewer seams. And one more thing is the pressure that the water in it exerts on the equipment. Cylinders carry it best.

Internal coating

For the inner surface of the tank, the most different materials- here and high-quality enamel, and a titanium layer, and stainless steel, and glass ceramics. There are also corrosion protection- the magnesium anode located inside the tank is responsible for it.

In some models, a fine-dispenser interspersed with silver is provided. This "know-how" allows you to claim the disinfectant properties of the water flowing from the device.

Simple and clear control

Even the cheapest brands of modern water heaters are sure to have temperature controllers and thermostats, which will turn on and off the heating in a given program in automatic mode.

And if the model is expensive, then it will a priori be smart, because in this case the work is entrusted powerful processor. Its task is not only to maintain the required temperature, but even to disinfect the water. Another "trick" users call the ability to draw up a user's schedule and, if necessary, turn on both heating elements for a faster result.

Usually such devices look stylish and presentable. The impression is completed by a touch screen, where settings and changes are made with a light touch.

Overview of water heaters from different companies

Many global manufacturers of equipment are ready to offer interesting models of boilers of their brand. It is possible to understand which water heater of which company will be better only by conducting a detailed analysis of the strengths and weaknesses devices.

Advanced "Ariston"

The leading position is occupied by products from Ariston. This Italian brand tries to keep abreast of global trends and produces high-quality equipment that meets all consumer requirements. Products are represented by boilers with a volume of 30 to 100 liters (and corresponding to the volume of power). The inner surface is also interesting - it can contain both simple enamel and the one with silver in the AG + marking. Titanium and stainless steel are immediately present. Of the benefits - the possibility of electronic control and even the presence of modern touch screens.

Additional features include divider application, which will not allow the heated and newly received portions of water to mix. It is also captivating that the developers took care of the likelihood of emergencies - in this case, the protective relay will not allow electric shock and prevent damage to the entire device. And the device itself simply will not turn on if there is no water in the tank.

It was not without some shortcomings. These include the lack of fasteners.

You can better understand the whole “essence” of the device using the example of the Ariston ABS VLS PW 50 model, which has average statistics - a tank of fifty liters and a power of 2.5 kW. This allows the 490x800x270 mm device to heat water up to 80 degrees. There is a mandatory thermometer and even a limit on the heating temperature. The protection provides for blocking the inclusion of the device in the absence of water. There are 2 heating elements, and the inner coating is stainless steel. The device is suspended vertically.

Users are also satisfied, talking about the fact that the equipment does not heat up in any way outside, with network outages there are no problems with it. By the amount of water, you can safely pour a bath, and there will be more to take a shower.

Elegant "Electrolux"

Another famous brand Electrolux has also stood the test of time (in 2019 it will cross its centenary milestone). Over the years, only one thing has not changed - the undoubted quality of products. But the functionality has only increased.

  1. In the models of this manufacturer there is a limit sensor, various relays for protection against overheating, there is a mandatory thermometer.
  2. The glass-ceramic surface of many models will not accumulate rust. In addition, there is a function for water disinfection.
  3. Cleaning the heating element is easy and simple thanks to a thoughtful process for this.
  4. Finally, the two-heater mode significantly saves electricity.

Electrolux is always flawless first-class products. But there were some drawbacks: technology is usually very expensive, and the heating elements themselves are short-lived in operation.

One of the most popular offers of this company is Electrolux EWH 50 Royal for 50 liters with a power of 2 kW. It heats water up to 75 degrees. It has rather compact dimensions - 433x860x255 mm and is mounted on the wall in a vertical form. The device is quite simple to operate (it has a mechanical one). Many protection options are provided: against overheating, against operation without water, check valves and safety valves. And in the functions, in addition to the standard temperature restrictions on heating, there is an accelerated process.

"Burning" for everyone and everyone

The Slovenian manufacturer Gorenje tries to meet the requirements of all its consumers. That is why all their devices are with very different power and volume of water. However, almost all of them have enamel and stainless steel as an internal coating. Also, the units are provided with hydraulic control, there is protection against overheating and a switch-on sensor, there is a safety valve.

For example, the Gorenje GBFU 80 E B6 with a size of 454x816x461 mm has a displacement of 80 liters and consumes 2 kW of power. Wall mounting in horizontal(which saves a lot of space) implies a lower eyeliner. The maximum possibility when heating water is 75 degrees. There is even frost protection. Users note that the device is very economical and quickly heats up water, but it has a problem of knocking out plugs, therefore, you need to think about pulling a separate cable.

Convenient "Atlantic"

The Atlantic brand produces boilers from 30 to 160 liters. There are horizontal and vertical mounting options. Interesting internal coating: inside the tank, it represents titanium alloy with cobalt and quartz inclusions(and this is already protection against water of the fourth class). Device owners like their stylish concise design and build quality.

The manufacturer has a compact narrow model size 338x918x345 mm - Atlantic O'Pro Slim PC 50 for fifty liters and a power consumption of 2 kW. The device has a maximum heating capacity of 65 degrees.

Specialized manufacturer "Termex"

Here you can quote the official website of the company: “There is a fact that cannot be argued with. If a company has been producing only water heaters for more than half a century, while its volumes have increased 20 times over the past 10 years alone, and its products are well bought in 160 countries of the world, then these are good water heaters. This is what true professionalism is all about.”

The equipment of this brand is not cheap, but Thermex boilers are always of excellent build quality, durability and efficiency in operation. The latter criterion is confirmed in the Thermex Champion ER 80V model, which has 80 liters of displacement heated with just 1.50 kW. The dimensions are quite compact even for small apartments - 450x730x470 mm, and the device is hung using vertical mounting. Users joke about this boiler: they say, it is from the “turn on and forget” series. The only drawback of the device is that every six months you have to change anti-corrosion anode.

domestic proposals

Which company would be better to buy a storage water heater for your apartment? Perhaps it will be one of the models of Russian manufacturers.

For example, a certain popularity in the territory of the Russian Federation was won by Alvin's boilers. The line called "Success" turned out to be successful - both in terms of quality and capabilities. The model "Success-15" will operate with a power of only 1.25 kW, however, the tank volume will not exceed 30 liters. The automation of the equipment will not allow the water to rise above 70 degrees (this will happen in about 40 minutes). Even a special system is provided that retains heat when the boiler is turned off. This is also facilitated by the 1 mm thick stainless steel used in technology, which has a positive effect on the durability of the boiler.

Boiler Alvin line "Success"

Another excellent domestic example is "Moydodyr". The brand also specializes in small heaters (about 15-30 liters), which is enough for washing dishes and for personal hygiene in the country. The device operates from 1.25 kW, is protected from overheating or the possibility of switching on "dry". The design itself is also interesting - a frame with a heated 20-liter tank and a sink (which resembles the famous fairy-tale hero). Full tank heats up in about 50 minutes, while not rising beyond the limit of 70 degrees.

Water heater "Moydodyr"

Which storage electric boiler to purchase must be decided based on the requirements of future users and their number. The main thing is to perform the installation correctly and follow the operating rules in the future, then the device will show itself as a reliable and trouble-free assistant.

An indispensable device in the country or in a private house without a central hot water supply. He allows you to quickly and without hassle to heat water for domestic needs- washing dishes, showers and baths. Water volumes depend on the type and power of the water heater, so it is important to consider all the features of the proposed models and choose the most suitable option.

There are several types of water heaters. Type of heating element they are subdivided into gas and electric. When installing a geyser, it is necessary to coordinate with the supervisory services and connect the chimney. Therefore, most consumers prefer to choose an electric water heater.

Electric water heaters according to the principle of heating water are divided into two types:

  • flowing;
  • cumulative.

Video: instantaneous and storage water heaters - how to choose the right option.

Flowing

main feature heaters of this type - no storage tank, due to which their dimensions are very compact. The instantaneous water heater can be installed anywhere, including hidden under the sink, in a wall cabinet or in a niche.

In a flow heater for heating water, a heating unit is designed, usually it is made of copper - corrosive resistant material with excellent thermal conductivity. The heating is switched on by means of a thermal heater.

The heating elements in the flow heater are turned on only when the water is turned on; for this, the device has a sensor that responds to the flow rate. It can be hydraulic, with a built-in diaphragm and stem, or electronic, with a microprocessor. Water supply and output are carried out through pipes. A mesh filter is provided at the inlet for water purification from solid inclusions and salts.

Flowing water heaters are open or closed type.

The former can provide hot water for only one draw-off point, for example, a sink in the kitchen.
Closed models can work for one or two points, for example, a sink and a shower.

For heating the right amount water, it is necessary that the water heater has sufficient power. For most household models, this figure is 3-8 kW, but can reach 25 kW. This water heater must only be connected by a professional electrician.

Advantages of flow models:

  • small size and weight;
  • simple installation and connection;
  • fast, almost instantaneous heating of water;
  • less energy consumption, as there is no need to maintain the temperature of the water in storage tank;
  • no need to pour water into winter period when the temperature drops, which makes it possible to use it in the country;
  • water is heated to a warm or moderately hot state, which eliminates the appearance of scale.

Minuses:

  • a large load on the power grid, consultation with an electrician serving the house is necessary on the permissible power of the equipment;
  • stringent requirements for electrical wiring - the high power of flow models requires connection to the network with a wire with a large cross section through a separate circuit breaker;
  • the water pressure in the water supply must be sufficient to trigger the flow sensor, otherwise the heater will not turn on;
  • if the house has more than two points of water intake, it is better to provide several instantaneous water heaters, the power of one device is not enough to effectively heat a large volume of water.
A flowing water heater is a good solution for a country house or cottage with a small consumption of hot water and sufficient power of the electrical network.

Mounting and installation

When choosing a model, it is necessary to take into account the dimensions of the device, while it is better to immediately determine the place of its installation. Compact dimensions usually allow you to install an instantaneous water heater hidden under the sink or above it.

You also need to buy and lay a separate cable to the electrical panel and connect it to a separate machine or RCD. The cross section of the cable cores and the rated current of the machine must correspond to those indicated in the table.

To ground the body of the water heater, it is necessary to connect the grounding core of the cable to the body of the electrical panel (6). The phase and neutral wires are connected to the RCD (5).

The pipes of the water heater are connected to the water supply as shown in the figure. A tee is connected to the cold water supply pipe (1), one outlet of which is connected to the cold tap of the mixer using a flexible hose or pipe. The second outlet is connected to the water heater by inserting a ball valve (3) and a strainer (4) into the pipe.

The outlet pipe from the water heater is connected to the hot tap of the mixer (2) also through the valve (3). Installing valves will allow you to easily remove the water heater for repair or maintenance.

Cumulative

A feature of accumulative models is the presence of a tank with a volume of 15 to 200 liters, in which water is heated and its temperature is maintained at a given level. The tank is made of stainless steel and coated with an anti-corrosion layer.

The body of the water heater can be steel, powder coated, or plastic. Between the tank and the body there is a heat-insulating layer that ensures the preservation of temperature. The shape of the body can be any, usually cylindrical or rectangular.

Water heating is carried out using one or more heating elements, which are turned on and off by a signal from the thermostat. It sets the desired temperature in the range from 35 to 90 degrees.

Cold water enters the tank through a fitting equipped with a check valve. The intake of heated water comes from the upper part of the tank, which excludes the discharge of water when its supply from the water supply is interrupted and the device overheats.

The power of storage water heaters usually does not exceed 2-3 kW, so they are suitable for any home, including those with old wiring. The water is heated to the set temperature in them within 0.5-3 hours, after which the device operates in the maintenance mode.

The water in the tank is always hot, so with a volume of more than 50 liters, you can not only take a shower or wash the dishes, but also take a bath. Several points of water intake can be connected to the storage heater, for this it is enough to select the desired volume of the device. To avoid pressure and temperature surges, it is recommended to connect the points through a distribution manifold - you can buy it or assemble it from fittings.

Advantages of storage water heaters:

  • the possibility of obtaining significant volumes of hot water;
  • you can connect several consumers - a bath, a shower, a washbasin, a sink in the kitchen;
  • low power and moderate load on the power grid;
  • stable water temperature.

Minuses:

  • large dimensions and weight of the device;
  • more complex installation and installation;
  • prolonged heating of water after switching on;
  • to maintain the temperature, the water heater must be turned on constantly, which increases energy consumption by 10-20%;
  • the formation of scale in the tank, which gradually reduces the efficiency of the device.

To avoid deposits on the walls of the tank and heating elements, as well as corrosion of the tank under the influence of low-quality water, modern water heaters are equipped with a magnesium anode. It takes over the processes of corrosion and salt deposition, while gradually collapsing.

Extraneous sounds during heating testify to its destruction - hissing, uneven hum. In some models, a light is provided that signals the destruction of the anode. In this case, it is better to buy a new anode and replace it.

Storage water heaters are suitable for use in the country, in a house or apartment with any pressure in the water supply, as well as with a low-power power supply.

Volume selection

Volume is one of the characteristics of water heaters, on which uninterrupted hot water supply at home depends. If water is needed only for kitchen sink or a washbasin, for example, in a small private house, then a volume of 15-30 liters is enough. For a large house, you need a boiler of 200 liters or more.

When choosing the volume of the water heater, its dimensions must also be taken into account. It is worth considering that boilers with a volume of 200 liters or more are usually produced in the floor version, less - in the hinged version.

It is generally accepted that for a family of 2 people a water heater of 50-80 liters is enough. It will provide hot water for the kitchen, bath and shower. For 3-4 people you need a 120-200 liter boiler.

Video about storage models: which heater is better

Installation and connection

When installing a wall-mounted storage heater, it is important to correctly calculate the load on the wall so as not to cause its destruction and the device to fall. The weight of the heater itself is indicated in the passport, it is necessary to add the weight of water to it. Based on the resulting value, you can choose the place of its attachment.

As a rule, for water heaters with a volume of more than 50 liters, choose bearing wall. For fastening, use the brackets and hardware supplied in the kit, and in their absence, anchor bolts and hooks.

When installing a water heater, it is important to observe it working position without any deviations. Heaters with a vertical installation are hung on two hooks, with a horizontal one - on four, for holes specially designed for this purpose.

A storage-type water heater is connected to the network in the same way as a flow-through one, but since the power of these devices usually does not exceed 2 kW, there are no special requirements for wiring. The device is grounded, the phase and neutral conductors are connected to the corresponding contacts of the RCD (7), usually it is installed in the electrical panel (8).

To connect a water heater to a water supply network, the diagram below is usually used. A tee is installed on the cold water supply pipe with a shut-off valve (1). To one of the layers, a pipe is connected to the water heater. A safety valve (4) must be cut into it. It prevents spontaneous draining of water, and also allows you to relieve pressure when the water is heated.

To drain water from the water heater, a bypass with a three-way valve (6) is provided. To supply air to the tank when draining the water, a tee with a valve (5) is provided on the hot water pipe. The outlets to the draw-off points are indicated in the figure by positions (2) and (3).

To fill the water heater with water, it is necessary to open the hot water taps, as well as the valve on the safety valve. Three way valve bypass must be closed. As the tank fills, air will come out of the taps, and after the water starts flowing, the heater can be turned on.

The choice of the manufacturer

An equally frequent question that arises when choosing a water heater is which company's device will be reliable, convenient and economical. As a rule, the buyer trusts trusted brands, and it is important not to overpay for the big name of the company.

The most popular devices on the market are well-known companies such as Ariston, Bosch, Electrolux, Thermex. These companies represent a wide range of models of different power and volume, equipped with modern automation. They are safe to use and durable.

Having considered all the characteristics of water heaters, you can make a choice in favor of a specific type of water heating and the manufacturer, and buy a device that meets all the requirements and wishes. At correct installation and operation, the water heater will last for many years, providing stable water heating.

Centralized hot water supply in apartments is a definite plus for city life. If earlier hot water was a luxury, now it is a familiar attribute of a comfortable existence. In apartment buildings, hot water supply schedules often change due to summer renovations. And in country houses usually there is no connection to the hot water system. the only way out for owners of apartments and country houses is an electric water heater. To choose the right boiler, you need to know some criteria and features.

Types and features of electric water heaters

They are very popular. The reason for this: an affordable source of energy and ease of installation (no need to call a special installation team). Undoubtedly, there are also disadvantages: the cost of electricity and the heating time (compared to a gas water heater).

Electric water heaters come in several types. The choice of a particular model depends on the following aspects:

  • from the area of ​​the apartment;
  • the number of service points;
  • the number of people in the family;
  • the dimensions of the room where the device will be installed;
  • its installation method.

There are many types and varieties on the market - manufacturers offer a huge range of quality products.

Tankless water heaters are small and easy to install. They consume a lot of energy and need a constant and high pressure in the faucet for smooth operation. Easy to install, suitable for most modern apartments. The device consists of a housing, a heating element, temperature and pressure sensors, and fuses. Depending on the design, sensors may be missing.

The heating tank looks like a narrow pipe through which water passes and heats up in the process. The heating element in this type of device is a heating element, an uninsulated coil or a shell-and-tube heat exchanger. The latter is a tube with heated water, which is located inside the device with a coolant. When using an instantaneous water heater, it is not necessary to install a mixer separately.

A water heater of this type has the only drawback - a large consumption of electricity. Otherwise, it has a huge number of advantages, the main of which is that the device very quickly picks up the desired temperature, immediately heats the flow, because it does not have a limiter in the form of a storage tank. A device of this type is chosen in the following cases:

  • hot water is needed constantly and in small quantities;
  • hot water is urgent and there is no time to wait for it to heat up;
  • not enough space for a large water heater.

In terms of operating time, a flow-type water heater is inferior to others; it fails faster than a device with a storage tank.

The instantaneous water heater has small dimensions and quickly heats the water

Pressure and non-pressure flow boilers

Instantaneous water heaters differ in the way they work.

Pressure "crash" into the pipe and supply hot water to several water points. Expansion tank it is not needed. Such devices have complex structure and high cost.

Non-pressure boilers provide a single point and are installed directly on the faucet. With such a device, it is necessary to use a thermostatic mixer, usually it comes with the device.

The principle of operation of an electric flow-type water heater is to heat the water with a heating element at the moment it flows through the heater. If we consider the process in detail, it looks like this:

  1. When cold liquid enters the housing, the pressure sensor is activated.
  2. The pressure sensor turns on the heater (one or more depends on the desired temperature).
  3. The fluid in the housing heats up on contact with the heater.
  4. The heated liquid exits through the outlet pipe to the faucet.

The temperature of the liquid at the outlet depends on the power of the device. Storage capacity not provided here. The decrease or increase in temperature is controlled by increasing or decreasing the pressure. The higher the power, the higher the heating temperatures and the greater the cost of electricity. Devices of this type are not recommended for use in old apartment buildings, because the wiring may not be able to withstand the power consumption.

In some models, the heater is additionally covered with heat exchangers so that it does not come into direct contact with water for a longer operation of the device and the safety of the heating element. They are called water heaters with "dry" and "wet" heating elements. Devices in which the heating element does not come into contact with water are fireproof and cost 2 times more.

Non-pressure electric water heater installed directly on the faucet

Instantaneous water heaters differ in the type of control:

  • Hydraulic system - the device has a simple design and a minimum set of settings, such as on, off and several temperature modes or their absence.
  • Electronic system - in expensive models of flow-type boilers there is an electronic control carried out by a microprocessor. They regulate the heating power depending on the flow and temperature of the incoming liquid, maintaining a constant temperature of the water at the outlet. If the pressure is very strong, the device's overheating protection is activated, and the water will stop heating. In some models, during a pressure drop, a pressure stabilizer is activated. In electronically controlled instantaneous water heaters, all information is displayed on the display: temperature, water consumption, current power. Additionally, a light indication can be installed, which warns of an increase in temperature above the set one. More modern and expensive models are equipped with a remote control. Price flow heater directly depends on the design: electronically controlled devices are more expensive, more reliable and more convenient to use.

storage type

A boiler of this type is convenient to use with a good electrical network and the need for a large supply of hot water. It is convenient, easy to use and reliable. It is optimal when a large amount of hot water is required, and the instantaneous boiler cannot cope with the load on the electrical wiring (usually this happens in old buildings).

The device consists of a thermos tank for storing water, a heating element and a magnesium anode, which is changed every six months, and a control panel with a thermostat. The equipment provides a volume of up to 1,000 liters, so it takes up a lot of space. Its main difference: the ability to deliver water simultaneously to several points of water intake and constantly maintain the temperature. The cost of such a water heater is slightly more expensive than a flowing one.

The storage boiler does not put a heavy load on the network, consumes less electricity, does not need a special one if its power is less than 3 kW.

For the device to work safely and for a long time, the following conditions are necessary:

  1. Grounding.
  2. Reducer to compensate for increased pressure in the water main.
  3. Safety valve to protect the water heater from excessive pressure in the tank and to drain if necessary.
  4. Non-return valve to block the drain of water from the tank (when the supply is interrupted), in order to avoid the combustion of heating elements.

Grounding, reducer and safety valve are called "safety group". Sometimes they need to be purchased separately, because they are not always included in the configuration. Often, manufacturers assemble these elements in one piece for ease of installation.

For a period of prolonged absence it is recommended to drain the water from the boiler in order to avoid the growth of bacteria and the breakdown of the device (if it is winter and the house is not heated).

The principle of operation of devices of this type is to heat and accumulate water and maintain the temperature at the same level like a thermos. Cold liquid enters through a pipe, then it is heated in a heating element to a predetermined temperature. Water is supplied from below, and the intake is from above, so it does not mix. The temperature of the water coming from the tank is stable. The task of thermal insulation in a water heater is to minimize heat loss.

If the device is constantly working at full capacity, it will quickly fail. The recommended optimum temperature for keeping water warm is 60°C. The device automatically turns off when heated to the desired temperature, and when it drops by a few degrees, it turns on again. The heating rate directly depends on the power and electricity consumption.

The design of the storage water heater allows you to heat a significant amount of water

Office in storage water heater is mechanical and electronic. Electronic systems work in energy saving mode, have a self-learning function: they remember preferences and adjust the temperature automatically. Mechanical control is preferable if the mains voltage is unstable.

Combined

This type of water heater is rarely used. It is also called an indirect heating boiler, the water in it is heated using a heat exchanger connected to central system heating or a separate boiler. In the summer, when the heating system is turned off, heating occurs with the help of a heating element. Thus, it combines the functions of two water heaters: indirect and electric. They consume a lot of electricity, and they are almost never used in apartment buildings. It is more rational to use such a device in a private house.

Thanks to its compact and elegant design, the water heater will fit perfectly into the interior of the kitchen or bathroom.

The boiler consists of a storage tank with a spiral installed inside it, into which the coolant from the heating system enters. In the storage tank, the water keeps the temperature always at the same level. Such a device is great for an autonomous hot water supply system, since its prices are quite low, and heating in heating period does not require additional costs.

During the heating period, the water heater is connected to the heating system (to the boiler) for indirect heating using a coil. Water enters the coil and heats up. Since little water is required for the heat exchanger, the efficiency of the boiler does not drop.

In summer, when the heating system is switched off, heating takes place in electric mode. A special element connected to the mains is responsible for heating. Energy costs are on the rise.

The larger the diameter of the coil and the power consumption, the higher the performance.

Design features of the combined electric water heater

The water heater has a control panel and an adjustable built-in thermostat that controls the temperature in the "winter / summer" mode. In the first case, temperature control is carried out by controlling the boot circulation pump, in the second - with the help of heating element control.

Liquid for giving

A bulk electric water heater is a great alternative if there is no running water. The device consists of a water tank and is equipped with a heating element and a tap. Water is poured into it by hand. The volume of the tank is 5-20 liters. Bulk water heater is popular with summer residents. It is easy to use and lasts a long time. The difference between the models in the design and set of functions. Most often, the water heater is represented by a cabinet, with a built-in sink and washbasin with a heating element. Under the sink is a container for draining. There are also models with a built-in shower hose. Such a device is plugged into a power outlet and used by summer residents in a summer shower.

The power consumption is small. The connection is made directly to the outlet, the heating element heats up and heats the water in a few minutes.

Bulk electric water heater is equipped with an overheating protection system

Heating of water in a bulk water heater is made by means of manual inclusion or in the automatic mode. In most models, an overheating protection system and shutdown when the tank is empty are installed.

How to choose a water heater for an apartment and a house: the main criteria

So, we figured out the types of water heaters, now let's move on to the criteria that are important when choosing a boiler:

  1. Volume of the tank. On average, water consumption per person per day is about 50 liters. 15 liters goes to technical needs, 30 - to take a shower. For a family of three, a 90-liter water heater is enough. Boilers up to 1000 liters are usually used in big houses and cottages.
  2. A heating element. Boilers with a "dry" heating element are expensive, durable and practical, while "wet" ones are subject to corrosion and salt deposition - this leads to a deterioration in heat transfer and repair of the device.
  3. Water heating rate. The larger the volume, the longer the water will heat up.
  4. Thermal insulation. The device must have high-quality thermal insulation - this helps to reduce energy costs for heating and maintaining the temperature of the water.
  5. Mains power and water pressure - are they suitable for normal and uninterrupted operation of the water heater. The larger the tank, the more power required.
  6. Anti-corrosion coating. The walls of the tank are constantly exposed to the aggressive effects of water, so they must be protected. durable coating. This coating includes enamel, glass porcelain, stainless steel, titanium coating. Stainless steel costs much more, but also lasts longer.

It is also necessary to determine the installation location of the device (wall or floor installation), for what purposes hot water is needed, determine the exact distance between the points of water intake, and find out the exact power supply.

Choosing a boiler depending on the number of water intake points

We calculate how many liters to choose a water heater for a family of two, five people, with a different number of points of consumption.

Water heaters of different sizes are required for different numbers of residents and water consumption points

The choice of electric water heaters is quite wide. A correct assessment of the criteria will help you choose a device that meets all requirements. After a choice of several models is made, it is recommended to compare the energy efficiency. It often makes sense to buy a more expensive model, as it can soon pay off compared to inexpensive models.
