Electric boilers Proterm
The main advantages of electric boilers are: relatively inexpensive price, low installation costs, fire safety, simplicity and ease of maintenance and operation, no boiler room, no chimney construction, silent operation, environmental friendliness. The main elements of the boiler are: a heat exchanger with electric heaters, a control unit, a pump and an expansion tank. It is important to note that electric boilers of low power come in two different versions - single-phase (220 V) and three-phase (380 V). Boilers over 9 kW are usually only three-phase. The overwhelming majority of electric boilers with a capacity of more than 6 kW are produced in multistage, which allows efficient use of electricity and does not turn on the boiler at full capacity during transition periods - in spring or autumn. In situations where power outages are possible, an electric boiler is often used in tandem with backup boilers, solid fuel or gas boilers. To save electricity, electric boilers are used in conjunction with two-zone electricity meters. The boiler turns on when the electricity tariff is low. But for this it is necessary to use a heat accumulator, which significantly increases the cost of the heating system.
