Wood burning boiler with 3 smoke circuits: before reaching the flue the combustion products run through a labyrinth made up from three segments.

1st segment: oxidation of combustion products thanks to the emission of secondary air;
2nd segment: the combustion products give up heat to the system water through the relevant fins;
3rd segment: the combustion products undergo the introduction of tertiary air for further reduction of emissions into the environment.

Large firebox for great autonomy, anti-corrosion cast iron structure, thermometer and heat regulator. Equipped with heat exchanger and safety valve for closed vessel installation.
They guarantee low pollutant emissions and high combustion efficiency.

Energy is available in 4 models: 21, 26, 30 and 34 kW.
