Many housing owners are thinking about how to choose a water heater flowing electric. Such models are characterized by smaller sizes and almost instantaneous heating of water. Unlike them, the boiler is a larger installation. With this device, you can avoid inconvenience when disabled hot water During preventive work.

What is flowing electric heater?

The flowing heater differs from the ordinary boiler primarily in the absence of a drive. Water heats up only at the time of use. It is possible to adjust the heating temperature of water with a change in pressure in needide. In addition, flowing heaters spend less electricity, since not spend it to maintain temperature. Due to its characteristics, the flowing water heater saves free place, electricity and time.

The water heater is a small-sized box, inside of which the tubular heating element is placed - TEN. The water heater acts in the following way: water enters the device, and then into the compartment, where the heating device is placed. Washing it, water gradually heats up, and then enters the taps hot.

The water temperature does not have higher temperature of the heating device, so the burning hot water does not have to wait.

Dear devices have a control panel with different sensors and timers. Inexpensive models Equipped with a thermostat that allows you to set the heating temperature. Some devices do not have regulatory systems - they only work in automatic mode.

To install the electric flow water heater, a wire is required separately from the shield. You also need a switch capable of working in automatic mode. The wire must be a strictly defined section.

A powerful network is required for the operation of the flow drive. Otherwise, you will have to choose the device whose power does not exceed 8kW.

Types of flow-type heaters

Before choosing a flow electric water heater, It is worth learn the varieties of this device. This will determine which heater is worth choosing to use.

Electric water heater flow-up May be the following types:

• pressure;
• handyless.

Pressure, or systemic, can be used in different conditions, i.e. from any crane that is in the house. Pressure water heaters are embedded in hot tubes cold water. Such devices have only output and inlet for water. The device is controlled by water pressure. System heaters are conveniently used during planned water disconnection in summer.

Performance are characterized by a small capacity (up to 8 kW) and power consumption. Operate only from one water point. Such heaters are suitable for the shower or use in the country. The maximum heating temperature is 30 ° C, which makes them useless for use in winter.

All year round, such water heating devices are used only in warm countries, where temperature fluctuations are not so significant.

The cost of such devices is usually low. The kit may include nozzles for the shower and mixers. If the water intake point is far from the heater, then it is better to install another nearby from it - it will significantly save money.

Calculation of the power of the heater and the selection criteria

Deciding with the type of device, select the optimal power. To do this, you will need a table in which all the necessary parameters are specified depending on the type of daily needs: flow rate and water volume, necessary temperature etc. The calculation of such a table may cause difficulties, so it is recommended to use a simpler method: it is enough to view the power of the heater and divide this figure by 2. As a result, water flow is obtained, heated to 30 degrees.

For clarity, you can use an example. If the power faced flow heater - 16 kW, then water consumption will be 16/2, that is, 8 m / min. That is, for the shower, this value is sufficient. Thus, a lot of hot water can be obtained only if the indicator is more than 8kW.

If hot water is needed not only for the shower, but at other points, then when choosing a heater, you need to consider the indicators in the most powerful one. If it is planned to use water at the same time at these points, the heater power must be increased at least 1.5 times.

Criteria for selecting heater

Before buying a flow heater, you need to decide for what purposes it will be used and where it will be installed.

If you need a water heater for seasonal use in the country, then there will be enough instrument with a capacity of 3.5 kW. For permanent use, the heater with a power of 5 kW is suitable, capable of heating even cold water in winter.

When choosing a heater, it is important to pay attention to the quality of the material from which the housing is made. The device is constantly exposed to high temperatures. The best way - Flowing heater with enameled housing. Such a device will withstand the temperature and exposure to the aggressive substances contained in the water.

Copper housing is also a good option, since it has a durable housing and protection of the heating element from scale. In terms of working in hard water such protection is enough for more than 5 years. It is time to replace protection that protection will be raised by the light bulb. Such devices with a copper case differ in very high cost.

Manufacturers of flowing water heaters

Deciding with the parameters, you can proceed to the choice of a specific model. Flowing water heaters produce the following manufacturers:

1. Electrolux is a well-known Swedish manufacturer, producing several limits of flow heaters. The instrument performance can be different. All models have a quality heating element with scale protection. The high price segment models are equipped with an intelligent control system.
2. Kospel. A distinctive feature of the water heaters of the Polish company Kospel is stylish designThanks to which devices always fit harmoniously into the interior. The heating element is made of high-quality copper. Kospel produces mainly pressure flow-type pressure heaters. There are two lines of non-pressure heaters. Service cost is quite low.
3. Thermex. The flask of the heating element in the heaters of this company is made from high quality copper.

When choosing a brand, it is also necessary to take into account the appointment of the device. If the flowing heater is purchased for use in the country, it is necessary to look at the ELECTROLUX or ATMOR brand models. Low power devices (from 3.5 to 5kW) perfectly cope with heat heating for the kitchen or soul in the country. It does not have to carry out serious repair of wiring. The cost of heaters of such brands ranges from 1.5 to 2 thousand rubles, but in any case they are accessible even to buyers with a strongly limited budget.

Most convenient model for home

To use at home, appliances from Thermex are suitable. They are not so expensive, within 7 thousand rubles, equipped with a temperature regulator. For reliable operation of the heater, it will be advisable to upgrade the wiring.

When choosing a heater for active use throughout the year, you should not choose the cheapest option.

The requirement of all expensive models is only one - the conditions of operation. Wiring in the house must withstand at least 20 kW. The network is needed at 380 V, so before connecting the water heater, there will be a serious repair of wiring. Alone to mount the heater is not recommended.

When we select a flow-type water heater, first of all, it is necessary to learn the capabilities of the power grid and clarify whether additional equipment will need to install the device.

When the model is selected, it is necessary to clarify whether there are spare parts on sale, it is necessary to estimate the front of the work.

With the absence and interruptions of hot water, preventive and repair work The heat network faces most of the inhabitants of cities. Would you like to forget about this problem forever? To do this, you need to buy a good flowing electric water heater. Water heaters are divided into flow and accumulative. The first have compact dimensions and heat the water instantly, while it passes through the internal elements of the device. Such a heating method is more efficient, but more energy-intensive. As for the accumulative water heaters, they have a large spacious tank, in which the water is located in the required temperature. Which water heater is better than the flow or accumulative depends on the specific purpose of the purpose of the household appliance.

To find out which flowing water heater is better to choose, we have a review - familiarization of the top 7 of the best electrical flow water heaters.

If in the house, apartment or in the country there is electricity, provide a family hot water Not at all difficult. The market presents exclusively wide selection Heating devices for heating tap water.

The most popular is the accumulative boilers, but the flow models have their own fans. To figure out how to choose a flow electric water heater, the features of the work of this device should be studied.

The design of the flow water heater is very simple. This is a flask for water, in which a powerful electric tank is installed, made of copper. Additionally, there is a control unit, it is possible to configure the functioning of the device in the desired way.

The flow of water enters the flask, where it is almost instantly heated to the desired temperature and is supplied to the points of distribution. More powerful models allow you to warm up the stream of up to 60 degrees, and less powerful - about 40 degrees.

The photo is clearly represented by the device of a household electric flow water heater, in which the role of the heating element performed high-power TEN

The variation of the characteristics of flow water heaters in power is quite wide, it varies within 3-27 kW. Up to 8 kW devices can be safely connected even to an ordinary single-phase outlet for 220 V, although electrician specialists recommend to spend a separate line from the counter for this powerful device.

High-power heaters can only be connected to a three-phase power grid by 380 kW, which is commonly equipped with houses with electric stoves.

If you need to connect powerful heaterBut there is no confidence in the reliability of your electrical network, it is worth consulting with an experienced electrician. Sometimes the network can be modified, but it does not always manage.

The advantages and disadvantages of "drocking"

Among the advantages of flow heaters should be noted a few points:

• This is usually compact devices, it is easier for them to find a suitable place.
• To obtain a stable flux of hot water, a separate reservoir is not required.
• Electricity is spent only during the device operation.
• The device is not difficult to install and operate.
• To install, do not need to do chimney.
• The operation of the device does not depend on the characteristics of the supply and exhaust ventilation.

But choosing a flowing water heater, it should be remembered about its shortcomings. To begin with, "drocks" during operation consume a rather large amount of electricity, which is inevitably reflected in utility bills.

In addition, the quality of heating will depend on how many points of the hot water consumption serves a heater simultaneously. If there are many such points, and the power of the device is small, the water will be too small, or it will warm up quickly.

Flowing water heaters are distinguished by compact sizes, which makes it easier to install them. Installation is important to comply with the requirements for power characteristics.

High power consumed requires relevant working conditions. Installation of an appliance with a capacity of more than 8 kW is possible only to a modern three-phase electrical network.

Unfortunately, the houses of the old building are not always equipped in this way. In such conditions, installation of flowing heaters with a capacity of up to 6 kW is allowed. You can clarify the features of your electrical network in the HSEK or at the local electrician.

It matters and the condition of wiring in the house. Of course, it must be good. It is recommended to use for such powerful devices as flowing heaters, high-quality copper wire.

The cable cross section should correspond to the power of the device. On this issue, you can also consult with a good electrician.

At devices low power There is a significant drawback: they are convenient for use only in the warm season, when the water temperature coming from the water pipeline is at least 15 degrees. A low-power device can increase the water temperature for another 25 degrees, i.e. To quite comfortable 40 degrees.

If water incoming to the heater for some reason does not have time to warm up to the desired level, the quality of heating will be unsatisfactory.

There are flowing water heaters that are installed directly on the sink. In this case, there is no need to bring to the sink separately pipe hot water supply

Attempts to connect a device designed for a three-phase network, to a conventional power grid in 220 V can become fatal and for a flow water heater, and for electricians, and even for people. Do not risk and arrange an electro-operator in the house. To private home ownership, cottage or cottage you can sum up with the necessary characteristics.

To do this, contact the local energy supply company and get a special permission - technical conditions To connect electrical installation.

With the features of the connection and operation of the electrical flow water heater, the electrolux with a capacity of 3.5 kW can be found in the following video.

What you need to know about the types of flow heaters

Although manufacturers are offered big choice Flow-type water heaters, by type of installation and features of functioning, they can be divided into two large groups: pressure and non-free.

The pressure models are mounted in the water pipeline, they are designed to simultaneously provide hot water of several consumption points.

The flow water heaters of the pressure type are connected directly to the water supply system of the house or apartment. They can serve several hot water consumption points at once.

The device is equipped with an entrance for cold water and the exit for the hot, from which water flows to places of consumption through the pipes.

Thus, if with the help of a flow heater, it is supposed to provide hot water all the apartment or the whole house, it makes sense to stop the selection precisely on the pressure water heater.

Non-free flowing water heaters are usually distinguished by low power, moderate price and high popularity. The device is equipped with special nozzles, for example, a watering can

Performance devices are used in cases where only one specific consumption point needs it in hot water. This is usually a shower room or bath, sink in the kitchen, etc.

The device is installed in the immediate vicinity of the point of consumption of hot water, cold water enters through the inlet nozzle, and the hot is fed through special nozzle, for example, through a watering can. The heaters of this type are a popular choice for the summer cottage.

Selecting the device: what to pay attention to

Before you go to the store, you should decide on the number of indicators that characterize the operation of the water heater:

• The number of consumption points to which heated water will be supplied.
• The total volume of water, which will be consumed per unit of time while turning on at all points of consumption.
• The power of the device that will provide a sufficient heating temperature.

In addition, a number of questions should be clarified in the store:

• The complexity of the installation of the device, which can be carried out independently or with the help of a specialist.
• The cost of installing the heater (sometimes you can get a discount or even free installation services).
• The presence and cost of spare parts that may be needed in the event of a breakdown of the product.
• The duration of the warranty period.
• Order of warranty service.

The last moment is very important, because sometimes you get a service for warranty repair from little famous manufacturer It is quite difficult, despite the fact that the warranty is provided. The center that carries out the warranty repair may be in the neighboring city, the region or even in another country.

The maximum amount of hot water depends on the power of the heater, which the device can produce per unit of time. Low power appliances can supply from two to six liters of water per minute. In fact, heating when using such an instrument is usually only 20 seconds.

Usually this amount of water is enough to quickly take the shower and wash the dishes. If the needs of residents at home exceed these indicators, you will need a more powerful water heater.

With this scheme, it is not difficult to determine which level of hot water requires a family for comfortable accommodation in the House

To find out the need for your family in hot water, it is possible to carry out simple practical calculations using a bucket of a well-known container, for example 8, 10 or 12 liters. Water is allowed with the usual pressure and flow the time during which the bucket will be filled.

Sharing the number of liters on the resulting number of seconds and multiplying the result by 60, determine the need for hot water for this specific point consumption. You can immediately share liters for a minute so that you do not have to multiply 60, but if the number of minutes is not intended, you should properly translate additional seconds in the tenth / hundredths of the minute. For example:

1 min.30 sec. \u003d 1.5 min.

45 sec. \u003d 0.75 min.

2 minutes. 15 sec. \u003d 2.25 min. etc.

The same practical measurements and simple calculations should be carried out for each point of consumption of hot water, and then summarize the result.

Information about the performance of the flow water heater is contained in the process of the product, and usually this indicator indicates the description of the goods on the sites of manufacturers, online stores, in advertising prospects, etc.

To determine the power of the flow water heater, it is possible to use a completely scientific formula that uses data about the needs of the consumption point / house / apartment in hot water. Calculate the power of the device according to the following formula:

P \u003d Q × (T 1 - T 2) × 0,073Where:

P. - Power of the flow water heater, W;

Q. - necessary duct hot water, l / min.;

t 1. - the necessary temperature of hot water entering the consumption point, 0 C;

t 2. - water temperature entered into the device for heating, 0 C;

0,073 - correction factor.

Here is an exemplary calculation of the power of the flow water heater for the conditional situation, when the level of hot water consumption is 15 l / min, the water temperature at the outlet should be 400 ° C, and at the input working temperature of the water on average is equal to 100 ° C.

In this case, the power of the flow water heater should be p \u003d 15 × (40-10) × 0.073 \u003d 32.85 kW. It is quite high power, the acquisition of such an appliance will be no longer sues.

Before choosing a suitable flowing water heater, you should evaluate the upcoming costs not only for its acquisition and installation, but also for further operation.

The higher the power of the device, the more the electricity is consumed during its operation, but the higher the temperature of the water that can be obtained using such an instrument. It all depends on the needs and specific conditions.

For example, if hot water is needed only for washing dishes or to take a shower, a fairly power model up to 8 kW. This device is enough to solve these small household tasks.

If you need hot water to ensure big houseEspecially throughout the year, and not only in the summer, it will have to consider devices with a capacity of 18 kW.

It is also worth estimating the location of hot water consumption points. Usually, if the shower cabin and the kitchen are near, it is possible to use one low-power device for these two points.

True, hot water will only be supplied to one consumer: or in a shower, or in the kitchen.

The scheme clearly demonstrates the features of the installation of a flow water heater. With the placement of the device and the order of its connection it is worth decreasing before the purchase

If funds allow, to improve comfort in the house using two small water heaters. One put in the kitchen, and the other in the bathroom or in the shower.

They do not occupy a lot of space, so the presence of two devices big problems Will not create. For the soul it makes sense to buy a water heater equipped with a block remote control. However, the device can be put directly in the shower.

Such devices are usually designed to work in conditions. high humiditySo the splashes are not terrible.

Some models of flow water heaters are equipped with a remote control unit. Such devices are very convenient to use in the shower

How much is?

It should be noted that in Russia the most popular is the flower heaters of Termex, Electrolux, etc. The models of the well-known company Bosch are distinguished by high quality.

AmartFix 5.5 T, SmartFIX 6.5 T, SmartFIX 2.0 6.5 T, 5.5-6.5 kW with a capacity of 5.5-6.5 kWs uses high popularity among Electrolux devices. The cost of such devices ranges from 50-70 dollars.

The stream 350, Stream 500, Stream 700, the power, respectively, are 3.5 kW, 5.0 kW, and 7.0 kW, 5.0 kW and 7.0 kW, can be called popular flow water heaters from Termex. The price varies around 80-100 dollars.

If you need to choose a high-power device, it makes sense to consider the line of flow water heaters from Vaillant. The cost of devices with a capacity of 12-27 kW ranges from 210 to 230 dollars.

In general, buyers are inclined to choose the low-power models of "drocking", which are easier and more convenient in operation. Where it is required to get a large amount of hot water, usually choose in favor cumulative water heaterWhich during operation costs a little cheaper.

This explains the low popularity of flow water heaters with high power.

To reduce the consumption of electricity and minimize the flow of water, ensuring sufficient water pressure, in the shower canes of non-pressure "drocks" make very small holes. Over time, these holes are clogged due to scale, as well as poor water quality.

After that, pollution is usually not difficult to remove the rigid brush or metal sponge.

The holes in the leak of the soul of the flow water heater specifically make small to reduce water consumption. Special filters will help protect the device from pollution

When a specific heater model is selected, it is recommended before buying carefully examine the manufacturer's instructions. This will help to understand the features of the installation of the device, as well as assess the features of its operation, i.e. As far as it is convenient to use the device after installation.

Small water heaters who acquire for the cottage, at the end of the season, it is recommended to remove and take it into a warm apartment.

In the spring, the heater is not difficult to connect again, but to ensure sufficiently good storage conditions on unheated dacha It may be quite difficult.

The domestic heating systems of the flow species are characterized by a simple control system and compact dimensions, since the additional reservoir does not require for operation. The process of work is to circulate water along a tubular heating element, where it instantly heats up to a certain temperature. The most optimal way to equip the house uninterrupted feed warm water - Set flow water heaters for the apartment.

Brief specifications

Modern equipment is divided into several types that suggest use in different ways Heating fluid:

• Heating spiral or Ten operates on the basis of electricity;
• The work is carried out by using the gas burner;
• Functioning due to the heat exchanger through which water passes and acquires the desired temperature mode.

The most simple in operation are considered electrical devices - They are very easily connected, work without problems, but consume a lot of electricity. The average power of such a heater is 3-5 kW.

The most economical is gas, but require the connection of the house to gas networks and establish their exclusively specialists with the tolerance category.

Rules for the choice of flow apparatus

To the task, how to choose a flow water heater for an apartment, you must approach the maximum responsibly. In order not to make a mistake in choosing, you should answer a few questions.

1. What is the device on the source of energy?

To date, there are two types of energy source: gas or electricity. If the house is heated gas boiler, you can generally acquire a two-round boiler, which heels and provides a DHW. Both contours are autonomous and in each other are not interconnected.

In the absence of gas, electric flow boilers are chosen, which are installed in the immediate vicinity of the water intake point - on the crane, on or instead of the shower, near the sink as an additional source of DHW, etc. The performance of the device depends on the type of wire installed. For example, in the old buildings, the shields are designed to maximize current supply to 16a. They can withstand the power of technology not more than 3.5 kW. Later buildings possess the shields that are withstanding 32-40 A, in this case, a powerful device can be used, with a value of up to 8 kW.

Regardless of the quality of the wiring and the year of construction when installing an electrical device, you should additionally hold separate wireheading from the unit to electrotic.

1. Type of technology

There are two types of equipment: non-variable and pressure. The apartment is more suitable for the second option, which the installation process is mounted directly on hot and cold water pipes. The device has the ability to provide hot water to several mixers immediately.

However, if the goal of acquiring the device is a seasonal overlap of centralized water supply, a non-valid version should be selected. Often it has less power and is equipped with additional shower nozzles. This unit is intended for heating the coolant only in the summer, in winter it is not able to effectively cope with the work.

1. Equipment performance

Here, more should be navigated, what water consumption consumption is required to carry out household purposes when taking into account the incoming and outgoing temperature regime. It is these parameters that are fixed in the passport of the flow water heater for the apartment.

To calculate, put a tank with a known volume and check for one minute. The number that will be given for this period of time is the main parameter to select the device.

Incoming water is fundamental importance. If it is at the mark of 14 ° C and higher, the exit will be declared by the manufacturer of degrees. The lower the temperature of the incoming, that, accordingly, it will be cool.

Experts recommend purchasing the technique of a well-known manufacturer. Since dubious products will significantly save attachments, but a little later, problems may arise with a quick breakdown of the unit and seriously available details.

Installation of poor-quality equipment to a house or apartment can lead not only to difficulties associated with its operation, but also a violation of the security of all real estate.

In order to figure out how to choose a flow water heater for an apartment, you need to correctly evaluate the upcoming load. A seven of four people will need a 14-16 kW device. The volume of water in this case will be 5-8 liters per minute, which is enough for 1-2 points of water intake.

The maximum temperature should be at least 50 ° C, but at the same time consider that in winter at the outlet it can be less than 3-5 ° C. Because it's about household useThe power supply must be designed for 220 V, the frequency of 20-30 Hz. If the house is private or there are regular voltage drops on the network, buy devices with a frequency of 30 Hz. If voltage stabilizers are installed, you can do 20 Hz.

Do not buy devices without overheating. The defense is necessarily present Marking Pip30.

As for the probes, it is better to prefer anti-corrosion, but some manufacturers have already released a line of static. And the one, and the other variety is equally well proven to operate.

When the choice is made, be sure to ask the seller-consultant certificate of quality conformity and do not forget about the warranty period.

Popular brands, models and reviews about them

As already negotiated a little earlier, the use of more powerful models is impractical for the apartment, as with a private house it is different. Therefore, we give examples of less productive aggregates that occupy leading positions on the technical market.

Water heater flowing electric for kitchen Atmor Basic 3.5 kW

Universal water heaters, which are in demand from consumers, but at the same time have a number of complaints. First of all, it concerns the lack of gaskets for the thermostat. Restriction of working frequency up to 25 hertz, that when the voltage drops on the network may affect the operation of the equipment. It is advisable to immediately install the voltage stabilizer and do not use the device at full power.

In the pluses - thermal switches, high-quality regulators and multifunctionality. Most provided 3 modes of operation. Price - 5500-6000 rub.

How to install the device?

First of all, it is necessary to install the apparatus directly on the wall, then connect to general System water supply.

Next requires a power connection. Even if the flow water heater has a low power, a separate electrically conductive should be performed for it. This process must be carried out on the basis of the factor that not each electric meter is able to withstand a large current load.

The diameter of the wiring and the type of automation is selected based on technical features Water heater and meter. It is important to remember that the standard socket, through which the technique is planned, should have a grounding element.

After that, the device joins the water supply directly to the crane or replaces a shower nozzle, depending on the configuration and type of device.

Domestic flow type water heater does not need a special accumulative capacity. The principle of his work is that the flow of water is reported required amount Thermal energy for the short period until it passes through the device.

• by means of electrical energy heating a tan or an uninsulated metal spiral;
• with the help of gas burner;
• with the use of a heat exchanger in which water receives thermal energy from a coolant.

The last of the listed options is extremely rare, one of the first two is much more often used.

In order to properly choose a flow water heater for the apartment, you must consistently answer a number of questions:

1. Energy source: gas or electricity? If in your house there are smoking channels and the HEAK permits the installation of gas equipment, then the most preferred option will be the installation of the gas column.

The power of the standard gas burner is even enough for heating water to shower in winter. If your home is not equipped with chimneys, you will have to install an electric water heater.

Its maximum power depends on the type of existing wiring.

For example, in old houses, in the shields of which fuses, calculated for the maximum current of 16 amps, can be installed water heaters with a power no higher than 3.5 kW.

During the construction of houses at a later period, the electrical networks calculated on 32 and even 40 amps.

Such wiring will withstand the power heater up to 8 kW. If you want to install a more powerful unit, you need to agree with the supply provider of the electricity supplier laying a separate power cable.

At the same time it is necessary to take into account that flow water heaters from 8 kW are calculated on three-phase voltage.

Thus, in apartment buildings, powerful "drocks" are used quite rarely, this option More suitable for individual construction.

2. Type of water heater: pressure or non-permanent? For the hot water supply of the whole apartment, you will have to install a pressure water heater, which is crashed directly into cold water supply.

Such equipment is capable of providing hot water to several points of water intake. If you just want to take a shower to take a shower during the summer shutdown period of hot water - choose a non-valve heater.

As a rule, such devices have a small power and completed with shower nozzles. However, it is necessary to take into account that they are suitable for heating water in the summer.

In winter, when the water temperature in the pipes drops to 5 degrees, the sense of a low-power non-pressure "drock" will be little.

3. What power water heater do I need? It will be much easier for you to determine not so much power as water consumption with known incoming and outgoing temperatures.

It is this parameter that the manufacturer indicates the passport of its equipment. Open the water in the usual mode and check for what time it is checked, let's say, water bucket with a capacity of 10 liters.

Recalculate the received data per minute and boldly go to the store. Now you will definitely choose the most suitable flowing water heater.

Be careful buy dubious products or frank fakes, even if the seller promises you a substantial discount.

Poor-quality electro-or gas equipment not only add you trouble with repair, but also may cause fire or explosions, the consequences of which will cost much more expensive.

When buying equipment, ask the seller to show quality CertificateAnd also ask what warranty period is provided to this equipment.

Popular electric heaters (cost and characteristics) ^

As already mentioned, the use of a powerful flowing water heater in the apartment is associated with great difficulties.

Therefore, in this review we will tell only about low-power devices that occupy leading positions in terms of sales. In our country, such brands have proven well:

1. Atmor Summer (Power - 3.5 kW, consumption - up to 3 l / min). Inexpensive budget class heater. It is able to "give" a temperature of 40 degrees, provided that it will be at the entrance no below 18. approximate cost – 800-1500 rubles.

2. "Polaris Vega T 5.5" (power - 5.5 kW, consumption - up to 4.4 l / min). Compact device is somewhat greater power.

Easy and comfortably mounted under the bath or washbasin, absolutely not pretending to the free space of the bathroom. Completed with a crane or shower nozzle (depending on the installation site).

3. Proton PEVN 5.0-220 (power - 5.0 kW, flow rate - 5 l / min). The approximate cost of this Russian model - 2500 rubles.

This device, like other domestic production, is good because its creators have tried to take into account the poor water quality in our water supply networks. Due to this, he is characterized increased service life.

4. "STIEBEL ELTRON DHC 3" (power - 3.0 kW, consumption - up to 3 l / min). This manufacturer can be safely attributed to the premium class, which, of course, was reflected at the cost of the model: 8000 rubles.

But for this money you get, how do motorists, "full minced" love to speak: Double protection against overheating, protection against water from entering (IP24), trouble-free German automation, as well as a convenient and informative indicator system.

5. "AEG MP 8" (power - 5.0 kW, consumption - up to 4.4 l / min). Another solid brand, the cost of one model fluctuates within 7500-8000 rubles.

A reliable and unpretentious device, a relatively high price is fully justified with quality and functionality.

Any water heater requires periodic replacement of the Tan. All about the wheels for water heaters, read here in this article:

Gas water heater flowing type ^

This type of flow water heater is more famous as a gas column. As already mentioned, the installation of such equipment requires harmonization with gas services, and also needs the exhibition of chimney. Exists two ways of ignition gas burner:

1. Ignition with wick. Such a column has a small gas wick, which is set up once, for example, in the morning and burns throughout the day.

It is from the phytyl that the gas burner occurs when the watershed crane is discovered. This ignition system is cheaper, but is characterized by ineffective use of gas.

2. Piezoelectric. Similar principle is often used in lighters for kitchen Plate. This system Works on the batteries, the spark is supplied automatically when the crane is opened.

Inexpensive models of gas "drock" have hydraulic control. This means that the flow of water simply includes gas burner.without adjusting its power.

In more expensive models, the "smart" electronics is installed, which analyzes the power of the water flow, the temperature at the inlet to the device and at the output of it.

In accordance with the data obtained, the valve is controlled on the burner, so that the unit always works in optimal mode.

An important requirement: in the room where gas water heating equipment is installed, the fortietha must be opened.

This is done to avoid carbon monoxide poisoning.

Installation of "Drour" with your own hands ^

1. Connect the heater to the water supply system. It is believed that the most common low-power flowing water heaters are exclusively in the summer when the hot water supply is disconnected in preventive purposes.

Therefore, the capital changes are not needed to install such a device. The rational output nozzle is connected to the soul tube, and the inlet - through the tee to the cold water supply system.

More powerful pressure water heaters, like boiler, connect by a reference scheme.

2. Connecting to the power grid. Even if the water heater has an average power - approximately 6 kW - it's all the same for connecting it need to stretch a separate wire from the shield.

This is necessary for the reason that most counters are not calculated on such a current load (approximately 27 amps).

The cross section of the wire and the type of protective machines (in this case, it is necessary to install the RCD) are selected by special tables. Remember that the outlet in which the water heater turns on should have a ground wire.

3. Connect to the gas highway.

Alone to perform such a connection is prohibited!

After the gas water heater is mounted and connected to the water supply system, you must invite a gas service representative, which will connect the equipment to the gas supply system.
