These boilers are intended for heating of individual houses with a central heating system. Solid fuel is used for burning — firewood, wood waste, coal, peat blocks. Fuel is loaded from the front or from the top. Burning process in the boiler is controlled automatically — using a thrust adjustor, the air damper is closed or opened. Effective valves prevent smoke from escaping into the room during the fuel loading.
The boiler is made of a steel sheet (casing wall thickness ~6mm) and pipes. The entire surface of the boiler is insulated with mineral wool that is covered with decorative shields.
