How to choose a flowing electric water heater: tips and acquaintance with successful models. Electric water heaters: what are and which one to choose

More recently, it was possible to brag about the purchase of a boiler, solving the issue of uninterrupted hot water supply. A little time passed, and the developers surprised with a new discovery - instantaneous water heaters that do not need time to preheat the water.

Many questions arise around flow systems: the possibility of using them in bathrooms, in summer cottages, the amount of energy consumed, the device, and the operating conditions. This article will help to understand them and other points.

The device of flowing electric heaters

Almost all systems flow type work on the principle of passing water through the body in which the heating element is installed. During contact with the heater, the water temperature rises according to the set mode. If the appliance is equipped with a power switch, you can set different temperature heating or completely turn off the water heater.

The design of the device is simple, anyone with knowledge of physics at the level of school curriculum. Most of the models produced have a similar device:

- heating element (TEN);

- entrance and exit openings;

- power point;

- terminals for connecting to the power supply;

— overheating sensors and ducts;

- overheating indicator;

- an element that provides for fixing the device to a sink or wall.

The power of the models varies from 3 to 27 kW;

The electrical type of connection provides for a 220 V power point;

Heating elements and non-insulated coils are used as a heater;

Are issued in two types (pressure provides hot water several points, non-pressure connected directly to the water supply at one point);

Adjustment is carried out in two ways (manually in hydraulic models, automatically by means of a set temperature regime electronic system);

Heating water takes only 1-2 seconds;

The volume of warm water is unlimited;

Electronic models make it possible to set a certain temperature;

The outlet water temperature reaches 36-40 degrees.

Advantages of flow heaters

The main advantage of flow systems is the economical consumption of electricity, and this is important and relevant for this period. The device does not waste energy on preheating. It only works when the water supply is in use. Another advantageous quality is unlimited quantity. hot water. Even a child can cope with the management of the water heater. To do this, just open the handle and close it if necessary. The device does not require maintenance technical measures, which saves money and time for the owners. And for the compact dimensions of the case, you can always find a place, without reducing the usable area.

An important factor is the direct supply from the water supply without a long stay in storage tank. So the quality of water is not lost, for pathogenic bacteria are not created favorable conditions breeding.

Price for flow models compares favorably with storage systems. This is another advantage in their favor.

Disadvantages of flow heaters

The main disadvantage of an instantaneous water heater is the provision of hot water supply to only one point. This may seem inconvenient, because in addition to washing in the kitchen, the apartment and house have a bathroom with several water supply points. However, you should not worry about this, because among the wide variety of flow devices, there are models designed specifically for showers. Buying multiple heaters family budget will be tangible, but during operation, energy savings will pay off the costs in 1-2 years.

Other disadvantages include:

- from the tap there is a supply of warm water, but not hot (about 40 ° C);

- the higher the power, the more energy the device consumes;

- the voltage in the network must be stable.

Based on the technical data, it can be concluded that flow systems are ideal for country houses, dachas, apartments, where water consumption is small.

How to choose a flow heater?

1. The main selection criterion is the power of the device. It should be remembered that the heating result depends on the initial water temperature. Therefore, in winter period she won't be as hot.

2. If a model is selected for installation in a shower stall, then the power should be within 12-15 kW. A device with a power of 6-8 kW will be able to provide a comfortable shower only in the summer in the country.

3. Heaters in the form of an uninsulated spiral are not subject to salt scale, but are sensitive to air pockets (they quickly burn out when working without contact with water). Heating elements often fail precisely because of the formation of scale. Salts will not affect the operation of appliances if the water supply is equipped with a good filter. This will prolong the operation of electrical installations.

4. When buying a water heater, you need to know what you need to connect it expendable materials, which entails a separate item of expenditure.

5. If the choice fell on pressure flow heater, where it is provided to connect several points, it is worth considering high cost such a device and the need to ensure high pressure in the plumbing.

6. After reading the reviews on the Internet, you can make a visual impression of a particular model.

7. Preference should be given to well-known trademarks. The eminent manufacturer values ​​the reputation of the company, so he will not complete the equipment with low-quality parts.

Before choosing, you need to decide in advance on the main parameters: the duration of the tap, the amount of water, the power of the device. This will help an experienced specialist to choose the right model.

By design, they are quite simple. As a rule, these are compact devices that are distinguished by good power and performance. The power consumption in this case depends on the manufacturer. In terms of control, these electrical appliances can be quite different.

Temperature control is mainly carried out using a switch, which is connected to a hydraulic mechanism. Pipe bends for convenient installation some models can be moved. In this case, the diameter of the nozzles can vary greatly. Also, instantaneous water heaters are available with various heating elements, and they use different thermal insulation.

If you plan to use an instantaneous water heater in the house often, then it should be selected with a power of at least 7 kW. All this will provide good performance. Additionally, the voltage limit parameter must be checked. As a rule, all models are capable of operating from a 220 V network, however, they can withstand different loads. If the house often experiences power outages, you need to think about purchasing a water heater with a powerful power supply.

At an operating frequency of 45 Hz, it can withstand a maximum voltage of 230 V. Depending on the type of heating element, the parameter maximum temperature is changing. If we consider modern models, then tubular elements are most often used there. By design, they are quite simple, and such electrical appliances will cost around 6 thousand rubles.

On the market, about 4200 rubles are asked for a running water heater.

These are the main and popular models of this utility. The final choice is yours.

Today, when there are more and more interruptions in hot water in the apartment due to the fault of the supplier, the desire of people to become completely independent of the performance of heat generating companies is becoming stronger. After all, as it usually happens, the prevention of systems in these organizations is carried out in the hottest time of summer and for quite a long time. ( sometimes there is no hot water in the taps for a whole month ) . You can deal with this problem by installing in your home household. Why electric and not gas? Yes, because to install a gas water heater (the so-called column), you will need to get a bunch of all sorts of permits ( and then, if allowed ) and spend a lot of money on its installation, because self-installation gas appliances is strictly prohibited! With electrical appliances, everything is much simpler, since you do not need to obtain any additional permits to install them. In addition, you can install and connect such devices yourself, guided by the manufacturer's instructions.

However, which one to choose hot water heater: storage or flow? The answer to this question is ambiguous, since it will require understanding the principle of operation of both types of heaters, which determines both the advantages and disadvantages of each of the electrical appliances.

That's it and let's talk about it. And let's start with storage water heaters.

How does a storage water heater work?

Advantages of storage electric water heaters

Based on the foregoing, we can say that water heaters accumulative type have the following advantages:

Now let's move on to the next type - flow type water heaters.

The principle of operation of electric flow type heaters

difference of this type heaters from storage type heaters in that they are able to very quickly heat the flow of water passing through the heating element of the device, due to a significant increase in the power of this thermoelement. All you have to do is open the faucet cold water to make it all through 10-15 seconds after passing through household boiler flow type, became hot enough. At the same time, not one heating element is installed in the device, but two or more, which can be used both individually and all together by turning on the corresponding toggle switch or button on the device control panel. That is, the stronger the water jet in the tap, the large quantity You need to use the heating elements at the same time so that the water has time to heat up to the desired temperature. It will be necessary to use all the heating elements at the same time in winter, when the water in the water pipes flows very cold. In the summer, when the weather is very hot outside, on the contrary, you can use only one heating element to get water heated to comfortable temperature. In more expensive models of electric instantaneous water heaters, automation is installed, which itself decides whether to turn on or turn off additional heating elements, depending on the amount of flow and water temperature. This allows you to achieve some energy savings when the house uses instantaneous electric water heaters. By the way, automation will warn a person with a sound and light signal if the water temperature reaches a value at which he can get a skin burn. The latest models of such water heaters can even be controlled using a remote control.

Well, at first glance, electric water heaters are no worse, and even better than similar storage-type household appliances. But let's not make hasty conclusions, but first consider what advantages and disadvantages they have.

Positive sides flow type water heaters

These household heaters have significant advantages over their storage-type counterparts, since they:

only work when water flows through them. This means that electricity is consumed only for a certain period of time, during which you can get any amount of hot water that you need;

They do not need to be equipped with a reservoir, therefore they have a very compact dimensions and low weight, which allows you to install them in any place convenient for you and does not require a main wall for mounting the device;

Manufacturers produce these devices in a very diverse design and color, which allows them to harmoniously fit into any room interior;

stand ( if it's not the most expensive models ) much cheaper than storage water heaters;

They can be easily installed by hand;

Easy to maintain as they do not require periodic descaling.

It would seem that you need to choose exactly instantaneous water heaters, and not storage ones, what else is there to think about. But let's also consider the disadvantages that such « wonderful » water heaters.

Cons of electric running water heaters

So, these devices have, albeit a little, but significant disadvantages:

1. If there is no electricity in the house (even for a short time), then you will not be able to wash or wash the dishes, as in the case when you would have a household electric storage boiler installed.

2. Hot water can be distributed only at one point, that is, only where it is installed this device ( e.g. only in the bathroom or in the kitchen ) .

3. During operation, instantaneous water heaters consume a large number of electricity, since such devices have a power consumption of 8 kW up to 10 kW ( this is the most optimal power for domestic use, although less powerful devices are also available, but they work with low productivity and cannot provide a normal flow of hot water ) . If you want, you can find an electric instantaneous water heater for sale even with a power consumption 30 kW! But before you buy it, calculate approximately how much you will have to pay per month for electricity if you install such a powerful device in your home, and only then make a decision to buy or refuse it.

4. The biggest drawback of this type of water heaters is a consequence of the previous one - for their connection to electrical network you can not use the standard line laid in the apartment / home because it can safely provide electric shock only devices connected to it, the total power consumption of which does not exceed 3 kW. And this means that to connect such a water heater, you will have to lay a separate line. I do not advise you to do this on your own. It is better to contact the specialists of the company with which you have concluded a contract for the supply of electricity. For a fee they perform technical documentation, will produce electric installation work and connect your instantaneous water heater to the network. By the way, do not forget to check the installation of the RCD in order to protect your home and your own life. To find out how it works and why such devices must be installed in an apartment / at home, read my article "Connecting a single-phase RCD with your own hands". In addition, if you still decide to lay a separate line on your own, then I recommend that you familiarize yourself with the material of the article. "How to choose the right electrical cable for wiring" where all the necessary information is available.

Now we can draw some conclusions.

Which is better: storage or flow electric water heater?

Let's look at the price factor first. Storage water heaters, even the most "fancy" ones, are much cheaper than their flowing "brothers" with good power consumption (8 kW - 10 kW ) and an extended list of available options. At the same time, storage water heaters, characterized by the same power consumption and the same volume of the water tank, can vary greatly in price, which depends on:

From the material from which the tank is made ( enameled steel, titanium or glass porcelain or stainless steel ) ;

From the thickness of the sheet of metal itself;

From the number of options available during the operation of the water heater ( for example, the presence of a programmable controller that allows you to set the exact date and the time the boiler is turned on, so that the water in its tank is already hot by the time you arrive ) ;

From electrical appliance design.

In addition, it will be necessary to "fork out" for electrical work on laying a separate line if you decide to install an instantaneous water heater.

Now let's turn to the efficiency of both types of water heaters. Contrary to popular belief, instantaneous electric water heaters consume about the same amount of electricity to heat the same volume of liquid as storage-type water heaters, although the former have much more powerful ( twice or more ) heating elements. This is because the flow heater consumes electricity only for a short period of time (as long as water flows through it), and storage water heater is forced to periodically turn on its heating elements throughout the day in order to maintain the set temperature of the water in the tank.

In terms of ease of installation, instantaneous water heaters, of course, win over « brethren » accumulative type, since they are small in size and do not require a main wall for their installation. However significant disadvantage they have the need to connect to the network through a more powerful than standard power line.

Instantaneous water heaters do not limit your hot water flow, unlike storage boilers, which cannot give you more hot water than their tanks contain. However, storage heaters allow for the simultaneous distribution of heated water at various points in the dwelling, although in small quantities ( for example, one person can do the dishes in the kitchen while another person takes a shower ) . In addition, if the light suddenly disappears in the house for a short time, then the water heated during the day in the boiler tank will still remain hot for several hours.

In service, electric instantaneous water heaters undoubtedly occupy leadership position, since in storage devices it is necessary to periodically descale the tank and change the magnesium anode.

What we have in the end: these devices, if you add up all the pluses and minuses, are almost equal to each other. That is, you yourself must decide what type of electric water heater it will be convenient for you to use. The main thing is that it serves for a long time, regularly and pleases you with the possibility of easy access to such a blessing of civilization as hot water. I am sure that now you can make the right choice!

The modern market for water heaters provides an opportunity to purchase devices that run on gas, electricity, solid or liquid fuels and have different power characteristics. Among such devices, flow-through devices stand out favorably.

This type of device has many advantages, including:

  1. compactness- water heaters are small in size, occupy a small area, which allows them to be hidden in specially made niches or cabinets, placed directly above washbasins and sinks.
  2. Instant liquid heating- at the moment of turning on the device, the water is instantly heated to the set temperature.
  3. Does not require a chimney– in contrast to the use of gas instantaneous water heaters, electrical appliance does not need a smoke exhaust system.
  4. Can be used in the garden- with electricity and running water.
  5. Adjustment accuracy– allows you to configure the device to produce hot water at a given temperature.

Flowing electric water heaters are not without drawbacks. Almost all devices have high power, which does not allow them to be used in houses with dilapidated electrical wiring, or with a limit on the maximum consumption of electricity.

Principle of operation

To heat the water inside the device, it is used, which, during the passage of the liquid, heats the water to the required temperature. The water heater allows you to completely abandon the mixer, due to the need for additional regulation of the liquid temperature.


Connection diagram for a flowing electric water heater

Varieties of heaters

There are two main types of instantaneous electric water heaters:

  1. Non-pressure - this type of heater is used in conditions low head water. These devices are indispensable in the country, where water supply is often carried out using a tank located more than high level than water users. Such a slight pressure of the liquid in the plumbing system is sufficient for the full functioning of the heaters. Non-pressure devices are low-performance, usually heating the liquid in such devices does not exceed 3 l / minute, but the power consumed by such heaters is much less. Non-pressure heaters can be used to provide hot water to only one point of consumption.
  2. Pressure - heaters, the operation of which requires pressure in the water supply system of at least 2 atmospheres. If the fluid pressure in the water supply is below this indicator, then it is necessary to install a hydraulic accumulator with a water pump and set the system to operating pressure. Pressure water heaters have a large capacity and can be used to provide several taps with hot water. If it is required to install equipment with a power of more than 12 kW, then devices for operation from a three-phase electrical network are purchased.


How to choose

Before purchasing a flow heater, you should accurately determine the performance of the device.
There is absolutely no need to purchase a powerful three-phase water heater for use with one draw-off point.

In this case, a small non-pressure appliance is suitable, which can be installed directly above the sink or sink.

In the case when it is necessary to provide several water points with hot water, pressure devices with a power of at least 8 kW are used. Such devices allow you to heat water in flow mode up to +70 degrees, with a capacity of 5 - 10 l / min.


Manufacturers and prices

Heater installation

To install an instantaneous water heater, you will need the following::

  1. Wrench.
  2. Pliers.
  3. Crosshead screwdriver.
  4. Electric drill and drill for concrete 6 mm.
  5. The cable is three-core, the cross section of which depends on the power of the connected device.
  6. Flexible reinforced hose for connecting and draining water.

Before performing installation work, it is necessary to turn off the electricity and turn off the cold water.
First of all, the water heater is released from packaging and plugs that are installed on its nozzles.
To install the water heater, fasteners are used, which is included in the device kit.

To fix the heater in the wall, a hole is made with a drill to a depth of at least 80 mm. Then the cable is connected to the heater according to the device diagram, while it is imperative to correctly connect the ground wire, without which the operation of devices of this type is prohibited.

The other end of the cable is connected to phase, “0” and ground at electrical panel. In this case, it is imperative that the electrical circuit leading to the water heater must be equipped with an automatic fuse.

After the connection is completed electric cable, the water heater is installed in place and screwed to the wall with dowels. After that, it is necessary to connect the water to the device. To do this, use a flexible reinforced hose, which is connected at one end to a tee, which is installed in any convenient place in the supply line. cold water to other household appliances and faucets. The other end of the hose is connected to the heater.

If a non-pressure device is being installed, then the hot water outlet is through a built-in faucet or shower head. In the event that a powerful, pressurized heater is installed, the hot water outlet must be built into the domestic hot water circuit. To do this, a flexible reinforced hose is connected to the outlet of the device, which is connected to the water pipe.

  1. If the water entering the heater has solid particles or is hard, a filter element must be installed at the inlet of the device. Some models of expensive heaters have a built-in filter, which reduces the amount installation work when installing such devices.
  2. If a bath heater is required, powerful three-phase appliances are installed with a power of at least 12 kW and a capacity of 8 l / min.
  3. The installation of a flow heater must be carried out in accordance with all the rules, which will guarantee trouble-free and safe work water heater. In the event that there are doubts about your own qualifications, then you should not install the heater yourself. It is better to contact specialists who will perform all the necessary work.

The water heater is becoming increasingly popular, making up for the lack of heat when the central hot water supply is turned off. These devices provide citizens necessary quantity hot water. affordable price, low cost electricity and ease of installation makes the equipment attractive.

The periodic shutdown of hot water makes it necessary to purchase water heaters that help provide comfortable conditions residence. Today, there are several types of water heaters on the market: flowing, storage, bulk and combined.

For backup use apartment buildings ideal option becomes a flow water heater. It does not take up much space and can provide the necessary heat without waiting for a long heating.

Flow type electric heater is produced by:

  • pressure;
  • Pressureless options.

Pressure plunge into water pipe. Such a system will be able to provide several sources of water analysis. Insert the device after the filter, providing more long term operation. An electric heater is able to heat water to the required temperature in a few minutes.

The principle of operation is simple. tap water from the pipe passes through a hot heating element, heating up to a certain temperature, and then enters the tap. In this case, electricity is spent only at the moment of switching on.

A pressurized water heater requires separate wiring, or connection to electricity designed for an electric stove. Models are single-phase 3 - 12 kW and three-phase from 3 - 30 kW.

Non-pressure options have less power, and only one point of analysis. They can be installed on the walls next to the faucet and connected with a hose to the water pipe.

The main advantages of flow devices:

  • Miniature sizes;
  • The room is directly to the analysis of water, reducing heat loss;
  • Electricity consumption only when the tap is opened;
  • Economic price;
  • Instant water heating.

Water taps are placed on such devices and are used only with guaranteed water pressure, poor pressure will disable the device.

Arrangement of an apartment: how to choose a flowing water heater

When purchasing an instantaneous water heater for an apartment, it is necessary to pay attention to some features. You need to make sure you have enough power. The device should heat water up to 40 degrees in 1 minute at a flow rate of 2 liters.

Choosing electric heater you need to pay attention to the casing of the device. Negative external factors and impact detergents can ruin the look. Therefore, it is better to choose a device with a special protective layer.

The built-in anode will help to extend the service life, which will protect the heating element from scale.

More expensive options equipped additional features. An electric water heater can provide economic current consumption. To do this, a special sensor is installed on it. With prolonged parsing, it reduces the pressure and temperature of the water.

The built-in thermostat will extend the service life, preventing the device from overheating. The temperature accuracy sensor will allow you to adjust required heat with an accuracy of 2 degrees. Such a device will allow water procedures without fear of temperature fluctuations in the faucet.

Properly selected hot water dispensers can create necessary comfort and save cash hosts.

Storage system: water heater

For constant interruptions in hot water supply, it is more expedient to buy a storage heating system.

Such devices are of 2 types:

  • Electrical;
  • Gas.

The first option is more secure and does not require special permission. The connection is made through an ordinary socket.

Such designs are suitable for private houses without gas supply. They do not require reinforced wiring and are easy to install.

Electric boilers - this is the name of a sealed tank, with a heating element located inside. Modern models equipped with a thermostat that regulates the temperature. For maximum heat retention, the tank is protected by a layer of thermal insulation.

The hot water tank is connected to the mixer. Under pressure, the boiler is filled with water. Teng heats water to a certain temperature and turns off. When parsing water, titanium is filled with cold masses. going on automatic switch on heating. Having reached the desired temperature, the unit turns off again.

Manufacturers produce water storage Appliances various capacities. The parameters vary from 5 to 120 liters. When purchasing a unit, it is necessary to take into account the required water consumption. To take a shower, 1 person needs about 30 liters of water.
