Criterias of choice
Unlike a gas boiler, an electric one works without fuel. It does not require a chimney and ventilation. Electrical units do not need to be installed in a separate boiler room. The device allows you to reduce heating costs and pay for heat at electricity tariffs.
When choosing a heating boiler, many parameters are taken into account. The main criterion is the thermal power of the unit. The calculation of power depends on the area of the building on which the device can maintain the required temperature. For 10 square meters of area, 1 kW of thermal power is required.
In the TOP below, the models are classified depending on the type of food:
- Single-phase - connected to the mains 220 V
- Single-phase / three-phase - suitable for 220V and 380 Volt networks
- Three-phase - connect to a 380 V network
This parameter is important for owners of country houses due to frequent interruptions and power surges.
According to the principle of work, the following types are distinguished:
- Induction. There are no heating elements in the design. The temperature of the coolant increases according to the principle of electromagnetic induction. This function is performed by a built-in induction transformer.
- TEN. Boilers based on a tubular electric heater. It works due to direct contact of the coolant with the heater.
- Electrode. Water is heated by the passage of an electric current through it between the electrodes. The liquid is ionized, releasing thermal energy.
Most electric boilers are electronically controlled and self-diagnostic.
When choosing, also take into account:
- Method of installation and strapping. Allocate suspended and floor. Wall-mounted units are compact and can be installed in living rooms. Floor-mounted ones are used for heating large buildings and are mounted in separate rooms.
- Efficiency factor (COP). A parameter that reflects the efficiency of the device.
- The number of circuits and the presence of a water heater. Most electric boilers are designed only for heating, that is, single-circuit. Rarely there are double-circuit models with a built-in boiler that are connected to two circuits. They provide not only heating of steel radiators, but also supply to the water supply pipes.
An important criterion is the manufacturer of the electric boiler. The market offers a wide selection of single-circuit and double-circuit boilers from domestic and foreign brands. Before buying, it is recommended to pay attention to the presence of an official guarantee and read consumer reviews about the product.
