We choose a water heater. Positive and negative properties. Rating of the best running water heaters for home

Before choosing a storage water heater, you need to understand what it is. The market today is a fairly wide range of products. Many consumers are simply lost and do not know which type of storage heater to purchase. The feedback of people who already have this unit in the house undoubtedly help to cope with the task. But it is also important to know the technical features of the instruments. Further in the article, we'll figure out how to choose a storage water heater.

General information

Simply put, the device is a system that includes a tank that has a heating element  and a certain volume. In it, water is given a certain temperature. In the future, it is maintained at the established level. It is very convenient in case there are any problems with hot water. If necessary, it can take a shower or a bath, and also wash all the dishes. In the conditions of constant interruptions with hot water, a person involuntarily thinks about buying a storage water heater. The feedback of many consumers speaks in favor of such devices. After all, in case of interruptions in supply, the unit will be simply irreplaceable. In addition, according to many buyers, the devices are easy to operate.

Classification

Manufacturers produce various storage water heaters: electric and gas. There are also combined models. Completely gas boiler  does not depend on electricity. This is an undoubted plus, as in some regions there are interruptions with him. In addition, gas is cheap enough raw materials. Therefore, such boilers are more economical in operation. All types of boilers have their disadvantages and advantages. Having familiarized with them, you can easily find the right model.

Power Features

Gas accumulator water heater essentially differs from the electric one. Its advantage is the heating time. The power of the gas model is in the range of 4-6 kW, while the storage electric water heaters produce 1.5-3 kW. As a result, there is a significant difference. For example, a water heater is equipped with a capacity of 150 liters. In this case, the gas cylinder burner can boast a power of 7 kW. Under the same conditions, electric heating elements can only give up to 3 kW. Thanks to this example, it can be established that the gas model will cope with heating the installed volume of water in about an hour or slightly more. In the same time electric water heater  can spend on a similar process up to four hours.

Features of the installation

Before choosing a storage water heater, you need to determine the place where it will be located. Installation of the gas unit implies some difficulties. First of all, an additional chimney construction is needed. The design of this model assumes open or closed variant  combustion chamber. The complexity of the installation depends on this factor. If the gas model is equipped with a closed combustion chamber, the cost of installation work  will be relatively small. Nevertheless, the device itself will be quite expensive. If you plan to install the unit with an open storage room, you will have to spend much more.

Economic Features

In this case, the advantage of the gas storage water heater, as the cost of raw materials is rather small. Nevertheless, the price of this unit and its installation exceeds the cost of buying an electric model. In the latter case, a separate power line is not required. The unit can be connected to a conventional electrical network. Therefore, the popularity of these models is slightly higher than that of gas.

Volume capacity

Talking about how to choose a water heater storage, it should be said about the capacity of the tank. This parameter should also be taken into account when choosing a boiler. The tank must be roomy. In this way, hot water  will suffice for all needs, even with a small margin. From an economic point of view, the purchase of a large boiler will be quite expensive. Accordingly, the payment for electricity or gas will increase substantially. In addition, in a standard apartment, it's not easy to place a model with a large tank volume.

Necessary calculations

Before choosing a storage heater, you need to consider the number of family members. Everyone has his own needs, as you know. In this regard, it is necessary to calculate how often and how much water will be wasted. For example, if you only need to wash the dishes, enough capacity, the volume of which does not exceed 10 liters. In most cases, the water heater is bought in order to realize various domestic needs. In particular, for taking a shower or a bath. Thus, it takes a lot of water. The standard volume of most baths is up to 185 liters. The calculation is made taking into account that it will not be filled to the brim. In addition, water will also be removed by the human body. This hot dilutes the cold. Accordingly, in order to take a bath, you need water with a temperature of up to 50 degrees. It will take about 80 liters. The water flow will decrease if a high value is established for the temperature heating of the water.

Expert opinion

Models having a capacity of up to 15 liters can be used for washing hands. A 30 liter storage water heater is suitable for taking a shower at a dacha, for example. Installation of such models is quite simple. They can easily be placed above or under the sink. In addition, these models are very economical. They are suitable for a family of three. Also there are water heaters with large volumes - up to 150 liters. They fit a big family. The characteristics of water heaters and the purpose are almost the same as those of the models described above. Boilers, powered from the outlet and up to 1000 liters, are designed for autonomous hot water supply throughout the house. On average, three people require a capacity of up to 150 liters. Accordingly, if the family consists of four people, then it will need a tank of up to 200 liters. The final choice of the model should be made in strict accordance with specific needs.

Important nuances

Having in the house a water heater with a storage capacity of 50 liters, it is not possible to take a bath one after another. To heat up the next volume, the unit needs time. Buying a water heater, consumers want to be able to spend water as they need, while not lacking. In this case, it is best to buy a boiler, the volume of which reaches about 160 liters. It is not necessary to acquire a larger capacity. It will be in demand only in those cases when hot water is required for a whole day, besides also in large quantities. Otherwise, its surplus will not cover the funds invested in the purchase of the boiler.

Internal coating of the tank

From the inside, the surface must be covered with an anti-corrosion material. It can be:

1. Stainless steel.
2. Enamel.
3. Glass Porcelain.
4. Titanium sputtering.

The material covering the tank depends on how much it is protected from corrosion. This, in turn, has a significant effect on how long the storage heater will last. The price, respectively, also depends on the coverage. Anticorrosive materials have a different degree of stability, from which their value is added.

Features of coatings

The most popular materials in this regard are glass porcelain and enamel. They are quite resistant to corrosion. Their cost is also quite acceptable. However, these coatings have significant drawbacks. They are very sensitive to sudden temperature fluctuations, as a result of which microcracks can form. A model of this type should be used if the heating temperature does not exceed 60 degrees. However, under such conditions, bacteria will develop in the water with time. Thus, raising the temperature to the maximum is a must. It is also worth considering that the warranty, which applies to tanks with such coating, does not exceed 1 year. Currently, the most resistant to corrosion is a special type of water heater. Inside they are covered with titanium enamel or stainless steel.   Instruments that have similar tanks can boast a guarantee that lasts 10 years. Accordingly, devices with similar sputtering are somewhat more expensive. But they also have shortcomings. Over time, weak points begin to appear at the welding points. There is an opinion that stainless materials, entering into a certain reaction with water, significantly affect the taste and smell of water. However, users who have been dealing with such models for a long time, do not note anything like that. Magnesium anode provides enhanced protection to the inner coating of the tank. It is necessary to replace it at least once a year. This will greatly increase the anti-corrosion protection. They are also provided in tanks, which are covered with stainless steel. In this case, their frequent replacement is not required. The fact is that steel is quite resistant to corrosion.

Heating Features

The time during which the water takes the necessary temperature depends on the capacity of the water heating element. As mentioned earlier, in this case the gas models are in the first place. Electrical power  under equal conditions it is half as much. As a result, the differences are very significant. It is worth noting that some models have two electric heating elements, or TEN. This, of course, is an advantage. If one of these elements burns, the boiler will still continue to work due to the operation of the other. If necessary, you can simply leave the heater turned on.

Comfort and safety

Not all boiler elements are aimed at heating water. Also there are parts that are responsible for the convenience and safety of using the unit. Thermostat is the main of these devices. He is responsible for checking the water temperature. It is desirable that the design of the device provides an additional thermostat. However, it is not available in all models. Also worth mentioning is the importance of thermal insulation. The thicker its layer, the better. In modern water heaters, the water cools about 7 degrees per day. In large models, the thermal insulation layer is larger. Accordingly, in appliances with small tanks, water will cool down quickly enough. It is recommended to estimate the dimensions of the magnesium anode. If the size of this element is large enough, it will not have to be changed frequently.

Unit cost

The price of water heaters varies in the following range: 170-645 dollars. The smallest model will cost about $ 120. Capacitive instruments from different manufacturers also differ in price. Many believe that the best water heaters are available in Germany. There is an opinion that they are very qualitative and therefore their cost is quite high. For example, German models are much more expensive than Italian ones. At the same time, they have no fundamental difference. You can say that their device is the same. The price varies depending on the quality of the device. Many say that German boilers are slightly larger than Turkish or Italian boilers. The thing is that they have a thick layer of thermal insulation. Thanks to this, the water cools down about 5 degrees per day. Thus, electricity is saved.

THERMEX products

Boilers of this manufacturer are distinguished by convenience, reliability and excellent quality. The storage water heaters of this company are a compact and high-tech equipment. Now these devices have become indispensable attributes of every home. With their help, you can easily solve the problems with the lack of hot water in the house. Any water heater accumulating "Termex" distinguishes favorably that it is made according to Japanese technology, which implies a special welding of stainless  become. This helps prevent corrosion of joints. To other advantages of these models consumers attribute the fact that they are equipped with an accelerated mode of water heating. This contributes to significant time savings.

Ariston products

The product line is very diverse. The minimum volume that a storage water heater has is 50 liters. In each model a steel enamel tank is provided. Also they are all equipped with a magnesium anode. This provides enhanced protection against corrosion. Gas water heaters of this company can be used for industrial and domestic purposes. The principle of operation is the same: without connection to the mains, on liquefied and main gas. Domestic water heater storage Ariston is a compact and easy-to-use device.

Hot water is not a luxury, but an urgent necessity. Therefore, if a centralized water supply system can not provide your home or apartment with hot water 24 hours a day all year round - it is worth considering the purchase of a high-quality and productive water heater. But how to make a choice? What type of device should I prefer? Is it worth pursuing the trade logo? These and other questions will be answered in this article. Moreover, we will back up our advice with practical information - and present to your attention the rating of the best water heaters for the house of 2017.

What are water heaters?

According to the principle of operation, all water heaters are divided into:

• flowing;
• accumulative;
• and boilers indirect heating.

The type of heating is divided:

• electric models;
• and gas.

Which water heater is right for you - depends on the tasks that the device will have to cope with, as well as the location of its installation. Let's take a short look at each type of device.

Flowing water heaters provide rapid warming up of water. Such devices give the opportunity to immediately receive hot water in unlimited quantities. Inside such a water heater there is a powerful heater. Water passes inside the device and has time to warm up to 45-55 °. In a minute, a good flow-through heater is capable of giving 3 to 5 liters of hot water.

Advantages of running water heater

• compact - the dimensions of the device allow you to place it in a confined space and even hide it in a small kitchen cupboard;
• the rate of heating water - do not wait for a half or two hours to go to the shower or wash the dishes;
• unlimited access to hot water - hot water will escape from the tap until the device switches off, the user is not limited to a liter storage tank, because it is simply not in the device.

Where the flow heater will prove its best - in a small city apartment, office or in the temporary kitchen of a summer house. In those places where household appliances are given a minimum of space.

However, in use running water heaters  there are nuances - first of all, they consume a lot of energy - electricity or gas. For some electrical appliances  even follow to pull a separate wire with a large cross section so that it can withstand such loads. The most effective and affordable models of this type of water heater will tell you our rating. After that, making the right choice will be many times simpler.

Accumulating boiler and its features

This type of device is economical, although it takes several times more space. It heats the water inside the storage tank, and the volume of boiling water is limited precisely by the capacity of the tank. But, you can get boiling water 80 degrees, while reducing energy consumption. The storage water heater can easily distribute hot water to both the bathroom and the kitchen at the same time. If you decide to choose electric water heater, you can independently cope with its installation and connection. For the operation of such a device it is enough just to plug it into the socket. Gas water heater will require the call of the master, but to heat water on gas is cheaper.

If you have a large family and you live in your own home - it would be wiser to pay attention to the storage water heaters. But, if the water runs out of the set temperature in the tank, the device will collect cold water and begin to warm it - at least an hour and a half. And this is not always convenient. Therefore, it is worth making a choice in favor of some type of device thought out and weighed.

Boilers with indirect heating are installed in those houses where there is autonomous heating. They use the energy that they produce heater  and the water is heated to a predetermined temperature.

Boilers of indirect heating are distinguished by economy and sufficient efficiency. But they will require quite a lot of free space to install and most likely, you will need the help of a wizard to correctly connect and start the system.

Which water heater is best for you, and we are ready to reveal the cards and name the most reliable, productive and durable devices for the year 2017 of different brands.

How to choose a storage water heater for an apartment? This problem occurs in many residents in homes without hot water supply. Even with hot water supply, long repairs and failures create some discomfort. In apartments and cottages in the presence of gas pipelines, this issue is easier to solve, flowing water heaters on gas work quite efficiently. In the absence of blue fuel, two options are possible: solid fuel heating and electric water heaters. AT apartment buildings  The use of stoves on wood is hardly possible, there is only one option - electrical devices.

Criteria for selection

A huge number of model rulers from different manufacturers creates a predicament when choosing a device. Councils of consultants are not always correct, because their main task is to sell the goods. To understand how to choose a water heater for an apartment, you should familiarize yourself with the main characteristics and possibilities different models, ways of their installation and operation.

The choice of a water heater for an apartment needs to be done according to the following criteria:

• the amount of water used per day;
• frequency of use of the device;
• power consumption;
• dimensions;
• number of parsing points.

How to choose a storage water heater for performance? Approximate water flow per day per person is 50 liters. This value should be multiplied by the number of tenants, after which it will be possible to select the required volume of the water heater.

How to choose a water heater by periodicity? For operation at short intervals the best option  there will be flowing water heaters. When used as the main source, such devices do not always justify themselves.

Which water heater is the most optimal in terms of power? The power of the device determines the heating rate. You should also take into account the condition of the electrical wiring in the apartment.

Flowing water heaters are small in size, they can be installed in the washing area. Some models are installed in the sink on the tube. Storage type heaters are much larger. For their installation it is desirable to allocate a separate room. Water heaters for the apartment can be installed in the toilet or bathroom.

The number of parsing points is determined by the type of heater. A flow type device can provide flow at only one point.

Flow and storage devices

Electrical devices for hot water can be divided into several types depending on the heating method and design:

• accumulative type;
• flowing;
• combined.

Which boiler to choose? The heater is a tank of a certain capacity, covered with a layer of thermal insulation and a protective casing. Can be installed in a vertical or horizontal position. The lower part is installed electrical components  heating, temperature regulator, magnesium rod. Choose according to the required amount of hot water. Also it is necessary to take into account the dimensions, the way of installing the water heater.

Electric water storage heaters will be the best option when used as the main source of hot water in apartments and small cottages.

Flow heaters are small in size. The power consumption is much higher than in the other species. For connection it is usually required to lay a separate cable from the input device.

To get rid of the disadvantages inherent in the first two types, manufacturers offer combined models. You can choose an electric water heater of a combined type if there is not enough space to install a cumulative and limited capacity for power supply.

Electric heaters of flowing and storage type can provide a limited amount of water. With large needs, it is worth paying attention to devices with water heat exchangers having a large capacity of tanks.

Heaters with heat exchange

Boilers are tanks with a tubular heater installed inside. The source of heat is water from a central or autonomous heating system. These are the best units for an autonomous hot water system with high flow rates.

How to choose a boiler? Devices differ in the type of heat exchangers:

• heat exchanger in the form of a spiral from the tube;
• pipe grilles with a set of straight tubes;
• additional tank of thin-walled metal.

The capacity of the tank is calculated similarly to the storage units. The water temperature will depend on the temperature of the heating system.

The boiler for the house will be an excellent solution with a great need for hot water. The disadvantage of the devices is the slow heating rate. For sale there are combined units with an additional electric heat source.

This method allows not only to increase the rate of heating the tank, but also to use it when heating is turned off.

The electric boiler (with an additional heat source) lacks the drawbacks of a classical design with a water heat exchanger. Which to choose a boiler, will depend on the capabilities of the heating system, the permissible consumption of electricity.

Hot water in a private building

How to choose a water heater for a private house? Fundamental criteria will be the required flow and the power supply capacity of the structure. For summer cottages in the presence of electricity, the most optimal option will be an electric water heater of the flow type. With a small size and weight, the device can easily be transported from place to place, installed and dismantled.

It is also desirable to choose this water heater for small production or commercial buildings, remote from the main building or functioning independently. When choosing, you should carefully check the possibilities of the power supply system of the building.

A water heater to choose for a private house follows the need for hot water and the possibilities of its heating. The cost of electricity is constantly increasing, but the price of other energy resources is not standing still.

The optimal option for year-round hot water supply of the house will be a universal device with the possibility of using several heat sources.

How to choose a boiler? To proceed follows from the possibilities of acquiring energy resources. In addition to traditional sources, manufacturers offer units with alternative heating methods.

What kind of water heater is best used in specific conditions, of course, the owners decide. Information and advice are provided for general information on different types of  heaters, their capabilities and disadvantages.

Why in the apartment of a water heater? Probably, this issue did not torment those who, during the traditional summer shutdowns of hot water supply, travel to distant countries. But most of the inhabitants of our country who managed to buy a heater, had time to appreciate the benefits of a hot shower at any time of the year and day.

How to choose a water heater for an apartment? For this, it is not enough to come to the store and compare prices. It is worth knowing that devices operate on gas and electricity, differ in volume, capacity, type of installation and position, material and many other parameters. AT modern apartments  rarely used gas water heaters, especially large volumes. Therefore, we will dwell in detail on popular electric models, determining the best options for different conditions.

Flow devices are compact and not expensive. Such a heater fits perfectly in the cupboard under the kitchen sink and does not take up much space on the bathroom wall. Installation takes a minimum of time. With such a "helper" you do not have to wash dishes and hands in cold water. The jet, passing through a heating element, the outlet has a temperature of 35-40 degrees, sufficient for a comfortable shower.

But along with all the advantages of these noiseless aggregates, there is a significant drawback - a large consumption of electricity. Therefore, flow models are more suitable for economical seasonal use during periods of hot water shutdown and for apartments in which, for various reasons, a hot cold water runs at night.

Note! If your wiring has not changed since the days of the Soviet Union, it is better to refrain from purchasing a running water heater or to make a complete replacement of electrical cables.

Flow-through water heaters are produced in two versions - single- and three-phase. Also, the models differ in the principle of work - pressure and non-pressure.

1. Single-phaseinstruments are more popular, power is usually from 4 to 8 kW, less often 12 kW.
2. Three-phase  equipment is considered professional, costs several times more expensive and is rarely installed in apartments. From single-phase such water heaters differ not only in power, design, functionality, but also the possibility of simultaneous servicing several water-pumping points.

Pressurized

Pressurized water heaters  Flow type is very simple and does not require special care / maintenance. They almost instantly heat the water jet, starting to work immediately, as soon as the tap opens. Such products are installed directly into the water riser.

Popular manufacturers of quality water heaters:StiebelEltron,Vaillant,Siemens,AEG,Unitherm,Clage, Timberk.

Non-pressure

Non-pressure water heaters of flow typeinstalled next to the source of water, can be equipped with a shower and a spout. A big plus of a non-primer is mobility. Such a device can be quickly installed if necessary and removed when the need for hot water supply disappears. But it is worthwhile to know that non-pressure water heaters are very small in power. Those. At the outlet of the heated water there will be no more than 1-3 liters per second or the water will not warm up sufficiently. Another drawback lies in the design - over time, the heat transfer of the heating element can decrease.

To comfortably take a shower, it is worth purchasing a heater with a power of 8 kW, but such devices require quality wiring and mandatory grounding.

A bit about performance

Productivity as the number of heated water volumes per unit of time is always indicated by the producers. However, in low-price models, this figure may be underestimated, because the incoming water t = 20 ° C is taken into account, while in Russian apartments the flow temperature in the pipes rarely rises above 15 degrees. On the contrary, large companies underestimate the productivity index, taking into account the minimum temperature of incoming water (only 10 ° C).

Therefore, it is worth purchasing high-quality products of famous brands, avoiding shelves with cheap products, even if the latter has fabulous performance indicators in the description.

Water heaters for flat flow-cumulative

The flow-storage devices are perfectly suitable for use in apartments. Water heaters are connected to a standard shower hose and a standard 220 V outlet. Even a housewife can cope with the installation. The power of compact water heaters is small (about 2.5 kW), but in only half an hour in the tank there will be enough heated water, which is enough to take a shower.

Popular manufacturers:  "Etalon" and "Termex".

Price range:  5-7 thousand rubles.

Storage water heaters or boilers are devices that not only heat, but also retain the water temperature for a long time. Use heated water is possible, even if the heater is disconnected from the mains. A single water heater is sufficient to service all plumbing. devices in the apartment.

Boilers are much more convenient to use than flow devices, but take up more space, and the installation has a mass important nuances. Such a device can not simply be removed from the wall and hidden in a cabinet, when the need for alternative source  hot water will disappear.

How to choose the tank volume

The volume of the tank, acceptable for an apartment, is from 50 to 100 liters. Such a supply of water is enough for a family of two or four adults and a small child. If periods of shutdown of hot water are short-term and hot water is planned only for domestic needs, it is worthwhile to install a more compact 30-liter boiler.

To calculate the approximate daily volume of consumed water, it is best to check the hydrometer readings by checking the indications at intervals of 24 hours. Approximate volume necessary water  for 1 day for 1 person is 230-300 liters. Since the water in the boiler heats up to 75-85 degrees, after which it is diluted with a cold jet, the output produces 2 times more warm water than was heated by the device. Based on this, one user will only need to turn on the 50-liter heater twice a day to provide himself with warm water for the whole day.

Method of attachment

Boilers are mounted on a wall in a vertical or horizontal position, installed in niches, under kitchen sinks  or on the floor. The latter type of installation is typical only for large models with a volume of 150 liters and above. Horizontal boilers are more convenient and compact, but are more expensive than vertical boilers.

It is very convenient for the hidden location of the heater under the sink, but most often the boilers are hung on the wall in the toilet or bathroom, next to water distribution. This is due to the design of devices that differ in the type of connection (upper or lower).

Tank

The tanks of the boilers are made of steel (including stainless steel), less often - copper (very expensive devices), as well as with coatings from biostratified porcelain, glass ceramics, enamel, titanium enamel. Novelty - coating with ions of silver AG + from the company "Ariston", not only protects the metal from corrosion, but also has a pronounced antibacterial effect.

Acquiring a tank, it is important to pay attention to the quality of its insulation. The best materials are polyurethane and polyurethane foam. Than insulation is thicker (optimally 35 mm), the longer the water in the tank remains hot, the less electricity is spent. The low weight of the volumetric device will indicate a low quality of thermal insulation. Such models are cheap and suitable for rare short-term use in cases of seasonal or emergency outages. energy.

The low weight of the device will additionally indicate the unsatisfactory quality (small thickness) of the inner tank. A thin layer of enamel quickly cracked. When choosing it is worthwhile to compare several models of the same size, pay attention to their mass and make sure that better products weigh\u003e 10% more.

Heating element and its power

The heater is a heating element made of carbon or alloy steel, copper, etc. TENs are dry (mounted in a sealed flask) and wet (contact with water, heating it). The heater should have a place for fixing the magnesium anode.

Vertical boilers often have direct heaters, in horizontal boilers they are long curved. It is better to choose the heating element with the longest length. Because short heater has a high temperature of surface heating and rapid formation of scale.

Fastening is carried out either with a nut ¼, or flange (diameter 42-72 mm, thread M4, 5, 6 or 8).

Conclusion: for installation in an apartment it is better to choose a water heater with a 2 kW powertower, a large surface area made of copper or "dry" (with a steatite flask).

Service

Boilers require periodic maintenance:

• cleaning of the internal tank and heating elements from scale;
• replacement of the magnesium anode.

Depending on the quality of the water, it is recommended that the service be performed once every 1-2 years.

1. Assess your budget and frequency of use. Expensive equipment lasts longer, but there is no need to spend a huge amount on a water heater, which will be used 2-3 days a year.
2. Think about where you set the water heater. Measure the wall with a tape measure and check if it will withstand the weight of the device. Dimensions of water heaters are specified in the instructions. The position and type of wiring are selected based on the available space in the room. Flat horizontal devices are aesthetic and compact, and vertical ones in the form of cylinders are cheaper. The volume of the water heater should be chosen based on the number of users.
3. Pay attention to all specifications. Specify the power of the heater, the material of the parts, the thickness of the thermal insulation (for boilers), the type of coating, the heating time, etc.
4. The interface should be understandable, and management - convenient. The best water heaters are equipped with remote control  and have an electronic panel on the case.
5. Acquire equipment of known brands with a significant warranty period. Do not forget to find out about the service center, installation and cost of spare parts.

We remind you that the water heater is purchased for many years. Take your time with the choice, compare prices and water heaters.

Video - Choosing a water heater

Interruptions with hot water supply in apartment buildings  in the summer time is common. Planned repairs carried out by municipal services are delayed not for one week. During this period, the townspeople have to forget about the usual comfort. Those who do not want to put up with this problem, experts advise to install a water heater. The variety of models of these devices on the market can put a dead end to the ordinary buyer. Many consumers do not know how to choose a unit for an apartment so that they have enough warm water for all household needs. To understand what is best, you need to know all the strengths and weaknesses of each type of model.

Types of equipment

Electric units according to their device and method of water heating are divided into several groups:

• flowing;
• accumulative;
• flow-accumulating.

Outwardly, all water heaters are similar to each other. The instruments are rectangular or cylindrical in shape. On the front surface there is a knob for temperature regulation. Their distinguishing feature is their impressive size, especially if the model is designed for a large number of liters. The flow-through heaters absorbed the advantages of both types of equipment.

The device, the principle of operation and installation of flowing equipment

A flow-through water heater is called a compact device capable of instantly heating water in unlimited quantities. High performance of the "protocharger" is explained by the principle of its operation. Cold water, incoming to the unit, instantly heated to 45-60 ° C, passing through the flask and built-in heating element - TEN. Rapid heating contributes to the high power of the copper TEN installed in the compact housing of the device.

The equipment perfectly copes with the task of providing hot water in the case of the operation of only one water point. Otherwise, the water flowing through the device does not have time to warm up to a comfortable temperature.

The diagram shows all the insides of the "protocharger" and its typical dimensions, which may differ slightly from the model to the model

This equipment does not need frequent and thorough technical care, and its lifetime can last up to several years. Therefore, flow models are an excellent solution to the problem of short-term absence of hot water supply in houses and apartments, as well as in public catering establishments, schools and other socially important facilities.

An important technical feature of any instantaneous water heater is high power, the value of which can fluctuate in the range from 3 to 27 kW. Not all wiring is capable of withstanding the connection of such equipment. Therefore, when choosing a model, it is necessary to pay attention to the power of the proposed devices.

Flowing aggregates having a power of 3 to 8 kW can be included in a conventional socket with a single-phase voltage of 220 volts. More powerful models are used in apartments with electric stoves equipped with sockets with a three-phase voltage equal to 380 volts.

The flow-through water heater with the upper type of connection is perfectly integrated into the kitchen set

There are different models of heaters and the volume of hot water received per minute. "Flowcells" with a capacity of 3-8 kW produce in one minute 2 to 6 liters of heated water, while the heating time is not more than 20 seconds. The most important household and hygiene needs of this volume is quite enough.

Take into account the needs of family members in hot water, as well as taking into account the technical possibilities of the electrical wiring carried out in the apartment. It is also important to rely on the rating, which is compiled on the basis of sales of equipment, when solving this issue. The most popular among Russians are the models of such well-known manufacturers as Termex, Bosch, Electrolux, etc.

Installation Methods

By the method of installation distinguish:

• Pressure flow units, which are built directly into the water riser, allowing you to alternately conduct several household procedures; these devices are recommended for installation in urban apartments;
• Non-pressure flow-through water heaters should be located only next to the water point, which makes them more attractive for use in cottages.

And this is how the plumbing and electrical work should be done:

It is necessary to connect the flow-through water heater through the RCD - it can work even without grounding

A major drawback of the operation of all the "protochnikov" is a large consumption of electricity. To minimize costs, you have to spend very economical hot water. Residents who do not want to limit themselves in this, install a storage water heating equipment.

However, not only in apartments this equipment is installed. Because of the large consumption electric power  Flow models are not used in homes with autonomous heating and water supply systems.

Manufacturers produce for these purposes storage water heaters, the volume of which can reach 500 liters. For residential houses choose models with smaller capacity of the tank, the value of which varies depending on the number of people permanently living in the range from 10 to 150 liters. Of course, such household appliances take up a lot of space on the floor or on the wall, depending on the model, but they always provide a sufficient supply of hot water in the house.

The storage water heater provides the necessary supply of hot water in the house or apartment

The unit is a round or elongated thermally insulated tank in which water is heated by the TEN to a specified temperature (35-85 ° C) and remains so for 2-3 hours. As soon as the temperature drops by only 0.5 ° C, the heater is automatically turned on to warm it up. Then it is automatically turned off. This mode of operation allows the device to economically consume electricity.

Internal arrangement of gas storage water heater

For the support of the set water temperature, the thermostat integrated into the design of any storage water heater answers.

Individual models are equipped with additional models:

• function of accelerated heating;
• antibacterial coating of the tank;
• manual or automated control system.

The advantage of this equipment in front of the "protochnikami" is that all models can operate from an ordinary outlet with a voltage of 220 volts. At the same time, the power of household appliances is only 2-3 kW, which is comparable to the capacity of electric kettles used in each house. However, low power consumption is not affected by the performance of the equipment.

Please note that these units simultaneously provide hot water all the points of water available in the apartment. Household appliances with large tanks will not only allow you to wash dishes, but also to take a bath for all family members.

What to consider when choosing equipment

Another thing to consider is the fact that more time is spent on heating for a larger tank. So, in a 10-liter container, water will be heated to 45 ° C in 10 minutes, and in a 100-liter tank, in 4 hours.

Estimated approximate water flow per person. Then the result is multiplied by the number of family members and the approximate volume of the tank is obtained.

Storage water heaters horizontal type  Accommodation saves space in the room

In addition, the availability of free space in the bathroom or toilet is taken into account. Most often, they place these household appliances there. To save a useful space of these rooms, you can lean towards the horizontal placement models that are installed under the ceiling. The instruments with a housing are selected, the design of which is best suited to the interior of the room. Although manufacturers produce and embedded models, which are hidden in niches under the sinks.

Absolutely all buyers think about the question, and which firm is the best water heater for your house, apartment or villa. Among Russians, the brands AEG, Electrolux, Ariston and many others are popular.

Installation of equipment

Wall models, which include appliances with a tank of up to 150 liters, have special brackets on the case. Hooks into the wall on the pre-marked places. Then the acquired equipment is suspended on these hooks. The model with vertical type  placing horizontally.

Schematic wiring for connecting the boiler - more detailed recommendations are shown in the video below

Outdoor equipment, the volume of which exceeds 150 liters, is installed on a level solid foundation. There are no additional fasteners for these models.

To connect the devices to the water pipe use a flexible line. The process of filling the tank is described in detail in the instructions to the device. Switch on the heater in the network after full filling of the container.

Flow-storage models

Flow-through heaters are universal water-heating appliances, combining all the best characteristics of both devices. The possibility of operating the equipment in two modes, their compactness and light weight, not exceeding 6 kg, and the ease of installation attract many buyers. The size of the tanks in such devices varies from 10 to 30 liters, which is quite enough for vacationers in the country outside the summer residents.

As you can see, the choice is quite large. If in doubt, do not forget about the consultants who are ready to answer all questions.

We live in a private house and in the kitchen installed a flow heater, and in the bathroom installed a large heater-storage. Began to notice that the payment for the electric power has sharply jumped, all the same the water consumption in the kitchen is considerable. The bathroom and kitchen are next to each other and the husband remade the system for supplying hot water from one storage heater. Now grief we do not know, the big boiler suffices for all needs of a family and for an electricity we pay less.
