🚱 Electric flowing tap water heater: what it is, how to select and connect nuances

Central A hot and cold water - one of the most convenient and necessary inventions of mankind. The finished water is the right temperature is fed directly into the apartment. But what if there are next to no communication, or there is no possibility of such a connection? But for such situations and need a flow electric water heater, faucet. The main thing that has been communicated at least cold water. This is the most important for the private sector, small towns and villages, which do not bring hot water line.

Why do I need a flow electric water heater on tap

Unfortunately, not all the settlements of our country have the opportunity to connect the hot water supply. Yes there settlements in the cities, too, there are areas that do not have hot water - especially in the private sector.

And the only simple and accessible way - use flow heater warm and cold water on the go.

Advantages and disadvantages elektrokrana for heating water

The most obvious plus instantaneous water heaters - compactness. It can be installed in any available spot. More precisely, it can be placed in the most convenient point - shell, bathroom or directly from the taps. Another important advantage is the use of electric power at the time of passage of water through the heater - the system can maintain a desired temperature irrespective of the water pressure and the reference temperature. While on the other hand this is the main drawback - the high consumption of electricity for heating. This factor is a deterrent for many buyers.

Structural features and operation of instant hot water tap

In the simplest case, the water heater is a small compact device with gander attached to it like a conventional mixer and a crane. Inside the housing are arranged the heating elements and the control unit. The cold water entering into the apparatus, passes through multiple tubes to the wrap to which summed heating element. Due to the long passage along the entire length of the heated water in the tube output is already hot - or necessary beforehand to temperature exhibited device.

Types of electrical flow valves - water heaters

All instantaneous water heaters are divided into two broad categories: pressure and gravity. Accordingly, the field of application and principle of operation is slightly different.

Pressurized model wall heater faucet-flow type

Pressure heater is most often used where possible to ensure a constant flow of water under pressure - in apartments and houses with summed systems for hot and cold water supply.

Box made directly to the water pipe. Thus the pressure heater type can serve multiple draw-off points - bathroom, kitchen and so forth. In fact, the water supply in this type of heater is due to the water pressure in the central system, if there is no pressure, the device will not function.

Gravity model wall tap-water heater flow type

Gravity model simply passes through a water heating coil and heats it. The pressure does not play any role, and even if water barely runs out of the tap, the heater will heat it anyway. This type is best suited for areas with unstable water supply systems - for example, or to give the private sector in the city.

Criteria for selection of an electric heater on the crane

To select relevant heater only a few basic parameters: overall performance, electrical power and degree. Also, the presence of additional functional carrier rather easy.

The power capacity of the unit

The average consumption of water in the kitchen is about 3-5 l / min at a temperature of 45-55 ° C. Shower characteristic temperature 35-40 ° C. To simply wash their hands enough 2-4 l / min at 35-36 ° C. Calculate the total capacity can be as follows: the number of liters per minute is multiplied by the temperature difference between the cold water and outlet hot, and then multiplied by 0.073. The formula would be: Power = number of liters ⋅ (hot temperature - the temperature of the cold) ⋅ 0,073. For example, for kitchen water at a flow rate of 3 liters / min and a temperature of 40 ° C the calculation would be: 3 ⋅ (40 - 5) ⋅ 0,073 = 7,6. That is, it is necessary to search for the device by about 8 kW. For occasional use in the kitchen much is enough, and 3.5 kW, especially in the old building houses, that can not boast of reliable wiring. To calculate the large volumes and characteristics necessary to apply the appropriate values.

The degree of electrical appliance and additional parameters

It is worth paying attention to the mechanisms of protection of the heating unit. In particular, it must be implemented in overheat protection, short circuit protection, filtration and various display methods. Also pay attention to the possibility of adjusting the outlet water temperature. This is optional, but important and convenient aspect of using the device.

What a cock-heater is best according to our editorial staff

It is better to consider the most appropriate valve in two different categories. The first involves the use of the kitchen, the second - shower. For kitchen use is better to buy a simple and inexpensive option of instant heat water faucet to 3 kW, some of which were presented in the article. This same analogy can also be found on AliExpress.com.

For a more extensive use - for example, in the bathroom, shower and wash - is better to use more powerful and efficient electric instantaneous water heater on tap, especially if the family lives in the house large. Perhaps the best option would be pressurized model that can serve tap in the bathroom and in the kitchen.

Nuances on the crane installation cylinder

In fact, nothing complicated there is not, especially if the installation is done on the finished water pumping point - the sink in the kitchen or in the bathroom. If the heater trim, how to fix it on the wall - a trick and it depends on the base material. Compact solutions, water-heater nozzle to the crane, which are also the mixer set is even easier. They are mounted in the same way as a conventional mixer. From the tap with cold water supply is supplied flexible hose that connects to the device. The device itself is mounted in a hole in the sink, in the same way as the mixer. The only problem - you need to bring a power outlet, which must be grounded.
