Solid fuel hot water boiler for larger central heating systems.

Boiler is constructed according to the EN 303-5. Steel materials used apply to EN 10025, EN 10028-2, EN 10120 i EN 10088-2.

Due its increased volume the heating chamber can be fed with more fuel – higher autonomy.

The whole boiler is insulated with appropriate mineral wool protection and its door with vermiculite.

Specific construction allows triple pass (draught) of heating air – third pass consists of tubulator tubes.

Efficiency of this boiler is higher compared to other models.

In order to allow constant and most efficient working circle, use of an additional tank AT (heat accumulator) is strongly recommended.

Boiler is easy to clean with included cleaning kit. Boiler has a thermometer included as well.

Draught regulator is not included.
