What is the instantaneous electric water heater in the shower: an overview

Such a device is different from the usual with boilers large reservoirHaving besides a great cost. This compact device, inside which the water passes when applying through the heating elements, and its temperature instantly rises. The device is quite convenient for a country or a country house. Flowing an electric water heater is not able to adjust the temperature, it must be done independently by adding or reducing the pressure. The stronger the water supply, the lower the temperature, and vice versa.

Instantaneous water heater: principles of separation by type

Instantaneous electric water heaters can be divided into types according to the following parameters:

1. installation site - they are installed in the shower, on tap.
2. principle of operation - pressure, free-flow water-heater.
3. control method - mechanical, electronic.

Each species has its own peculiarities, which we now consider.

Separation of such water heating device at the place of installation

Despite the similarity of the principles of the heaters on the faucet and shower, there are some differences between them. Let's try to understand how they are essential.

Electric instantaneous water heater on the shower: features and nuances of use

Such devices are similar to the small box, usually mounted under the sink. To it are connected hose 2, one of which water is fed into the device, and the second output to the already heated shower. Temperature, as already mentioned, is regulated water pressure. Of course, the choice between a storage and instantaneous water heater for the shower is not unique - each There are pluses and minuses, but for the cottages, where no one lives in the winter, the flow option is suitable more. In addition, it can be easily disassembled and transported to another location, but not so on a storage tank water heater.

Flowing an electric heater on a crane: What is different from the device for a shower

Such devices can be divided into two types - mixers and nozzles on the crane. First - are devices that resemble in appearance a conventional mixer, slightly increased in size. In addition to powerful heaters, it is equipped with:

• protection against water hammer;
• pressure sensor which deactivates the heater when the pressure in the system over 0,7Pa or if the pressure is below 0,004Pa;
• flow sensor and the thermostat - if water is suddenly turned off, these devices save the burnout of the heating elements;
• automatic cutout - will power short-circuit or power surges.

The separation device according to the principle of work: a very important point

According to the principle of operation of these devices are divided into pressure and non-pressure flowing water heaters. there are fundamental differences between them, which we will now analyze in detail. After that, dear reader probably will not remain questions on the type protochnika for hot water.

Discharge electric instantaneous water heater: features and useability

Pressure flow electric water heater - a more powerful device allowing the connection of several intake points. This may be a bathroom, kitchen, shower. Such devices may be single phase (up to 12kW) or three-phase (up 27kVt), with the upper or lower connection. This allows the unit under the sink or over it. Such household instantaneous electric water heaters are installed in private homes or apartments are not equipped with hot water. Only turn on the device when there is pressure in the system, hence the name - pressure.

Free-flow water heating appliances where they are used

Non-pressure flow water heaters shower or faucet used in the country or in the garden house. Their thickness is much lower, so they can be connected through only one point of water intake. This can be a sink faucet or showerhead. Most often they are in the form of the mixer, but may appear as a separate unit. The power of such free-flow devices less than 8 kW.

Method protochnikom control: how it can be

A method similar to the instrument control can be mechanical or electronic. On this will depend heavily on the cost of the heater. Try to understand that it is cheaper to buy.

Mechanical control - all the familiar and the familiar version

About motor operation will not talk a lot, everything is clear. Turn tap water begins to flow. The greater the pressure, the lower the temperature of the water from the faucet or shower. The cheapest, but it is the least cost-effective option.

Devices with electronic control - compare with mechanics

Such devices are much higher, but those who bought them, they say that it has paid off. Energy saving face. What is the focus? And the fact that the electronic models allow you to set a certain temperature, regardless of the water pressure. Intelligent electronic control unit will reduce the voltage applied to the heating elements, thus saving energy, and very significantly.

Of the minuses, besides the high cost, there is another - if anything in the electronic device fails, the change will have the whole block, and it costs a lot. However, this happens very rarely.

Nuances connect electrical flow heaters

The main task - to see if the wiring is able to withstand the home power consumption of an electric heater. If there is the slightest doubt, it is better to play it safe and hold the shield from the opening a separate line with his own gun. Protochniki mounted in different ways. Some connected directly inside the body (in this case, looking at the contact marking), require different outlet assembly (single or three phase). The algorithm is as follows: first, draw a line (without connection to the power supply) is switched to the instantaneous water heater and only after power is connected. It is very important!
