Structurally, Protherm electric boilers are mechanical device , consisting of a heating element in the form of heating elements, an electronic control unit, a circulation pump, an expansion tank, an air vent and a DIN rail. The number of heating elements depends on the power of the model and the number of phases. Thus, low-power single-phase devices have one single-phase heating element, while powerful three-phase units are equipped with three single-phase heating elements. The control unit consists of an intermediate relay, fuses, terminal clamps and a power supply. The correct operation of this particular device determines the timely shutdown of the system in the event of emergency situations or power surges in the network.
The circulation pump pumps water into the system and maintains operating pressure in the circuits. The DIN rail serves as the basis for the installation of modular equipment, including a relay, an RCD and a voltage stabilizer. The air vent operates automatically and is needed to release accumulated air and steam, as well as to prevent the housing from exploding in the event of emergency overheating and water boiling.

The security system is represented by overheat and pressure sensors, as well as safety valves with pump anti-blocking function. All models are equipped with an RCD system that protects people and animals from electric shock if they touch a faulty device. To automatically reduce the boiler power when other electrical appliances are connected to the home network, the security system is equipped with a special load regulator. This will prevent automatic current shutdown from triggering in case of network overload. Many models are equipped with frost protection, which automatically turns on the pump when the temperature drops to 8 degrees, and heating elements when it drops to three degrees.
The boiler is controlled using a liquid crystal screen with a clear and convenient interface. The devices have single- and three-phase versions and are capable of operating from a network with a voltage of 220 and 380 W.

Therefore, wiring of 1.5 square meters and a three-phase 10 A circuit breaker will ensure normal operation.
With a single-phase network, everything is somewhat more complicated. The boiler has 6 heating elements installed and with a maximum power of 6 kW, the current consumption will be slightly more than 27 A, therefore, you will already need a wire with a cross-section of at least 6 squares and a 30 A circuit breaker. All of the above applies to any electric heating boiler for the home, of any power , only the current consumption values and the required wire cross-section will depend on the power.
According to the tables for choosing a section copper wire a current of 1 A requires a cross section of 0.17 mm2. The current in the circuit is determined by the well-known formula - I = P/U, in which:
The first thing you need to pay special attention to is correct selection sections electric cable nutrition. After all, for example, an electric boiler Proterm Skat 24 with a rated power of 24 kW, when connected to a three-phase network, will consume a current of about 30 A for each phase. It is not advisable to connect such a powerful boiler to a single-phase network, because in this case the current at maximum power will increase to 100 A. An electric boiler must be connected only through an RCD.
As for the installation location, the requirements for installing electric boilers are not as stringent as for gas or solid fuel units. And the price of an electric boiler for heating a home is much lower than the prices of other types of boilers.
You can install an electric boiler anywhere, but this place should provide easy access for adjusting the unit or quickly shutting it down if necessary.
If the circuit diagram contains several electric boilers, they are connected in parallel. According to electrical safety regulations, an electric heating device must be grounded.
How to choose an electric boiler for heating your home
All are compact, easy to use and safe. They do not need chimneys or special premises for installation, and the efficiency is close to 100%. These properties make them superior to other types of boilers. To heat a specific room, an electric boiler is selected primarily based on power. It is believed that one kilowatt is sufficient to heat 10 m2. Consequently, the electric boiler Proterm Skat 12 with a rated power of 12 kW can provide heat to rooms with a total area of 120 m2.
High quality and reliability are confirmed by reviews found on the Internet for the electric boiler Proterm Skat 12, in which they write that the boiler is silent, simply and easily adjusted and does not require constant attention (“installed, turned on and forgotten”).
Popular electric boilers from Protherm
To connect as a backup to existing system heating or for heating small house with an area of up to 90 m2, the wall-mounted electric boiler Protherm Skat 9 kr 13 with the ability to use a 220/380 V network is in greatest demand. The boiler is single-circuit with electronically controlled and with built-in circulation pump And . Its main characteristics fully correspond to the base model.
If there is a need to organize hot water supply, the manufacturer has provided the possibility of connecting an external tank. When sold, the connection pipes are closed with plugs. The price difference between single-circuit and double-circuit boilers small. For example, the price of a Proterm Skat 9 kW wall-mounted double-circuit boiler is comparable to the price of a boiler of similar power, but single-circuit. In different stores selling heating equipment, the price of the Proterm Skat 9 electric boiler ranges from 490 to 560 USD.
In terms of their technical characteristics, requirements for installation, adjustment and design, electric boilers are significantly preferable to gas and. Their installation does not require availability separate room, and the electric boiler itself can be installed anywhere in the heating circuit, the main thing is that it has easy access. Electronics developed by Protherm independently monitors the level of air temperature in the room and creates comfort and coziness in the home. The only obstacle that limits the use of electric boilers is the high price of electricity, which tends to increase.
