Professional level

The boiler is designed for efficient heating of apartments, residential buildings, shops, cafés and other premises up to 90 m2. The three-phase connection allows the device to be installed in rooms with a 400 V power supply. The silent operation of the boiler is ensured by the use of a relay as a switching element. Three levels of power regulation and a high-precision thermostat with a hysteresis of 1 ℃ allow setting the desired temperature smoothly, maintain it efficiently and reduce energy costs. The boiler is connected to the heating system through the direct supply pipe at the top of the device and through the return pipe at the bottom. It is also possible to connect a third-party pump, external room thermostat and programmer.

Guaranteed protection

Inside a high-quality IP22 steel shell with a zinc coating, there are reliable heating elements made of stainless steel, which guarantees the highest corrosion resistance. To increase the reliability and durability of the boiler life, the supply pipes in it are also made of steel and coated with zinc. There is also additional protection against electric shock and from exceeding the temperature of the coolant for the user safety and boiler durability. When the device is connected to the electricity network and in an emergency condition, the warning sign will be indicated by the corresponding indicator.
