Boiler PyroBurn Alpha

Wood gasification.
The wood in the primary burning chamber is fired in a low-oxygen environment reaching about 580°С. It starts degrading to a combustible gas of carbon compounds which is directed to the orifice of the secondary combustion chamber. There, the gas is enriched with secondary air and ignites to reach temperature of up to 1200°C.

Before leaving the boiler body, the gas passes through a flue with built-in spiral turbulators where it gives away its heat to the water mantle and cools down to 180°С. Thanks to the wood gasification principle the fuel is most efficiently consumed with minimum carbon emissions and ash.

Boiler warranty : 2 years

3.Secondary air;
4. Ignition;
5. Pyrolysis combustion;
6. Fume exhaust fan;
7. Flue



Product Features:

  • The built-in proportional-integral derivative controller monitors the burning process and controls the fan speed to achieve optimal yield and economy of fuel;
  • Fume exhaust fan;
  • Fume extraction device on the upper combustion chamber keeps smoke from polluting the boiler room during reloading;

Boiler PyroBurn Alpha - valve

  • Large firebox door ensures easy loading even with bigger logs (length of logs up to 50 cm);
  • Combustion chamber protected on all sides by ceramic plates;
  • Eyepiece for viewing the combustion process;





Safety devices:

  • Upon reaching 95°С the controller turns the fan off and activates the pumps for domestic hot water and heating system. An independent STB thermostat shuts down the fan upon reaching 99°С.
  • Safety heat evacuator;
  • Pressure relief valve 3 bar;

For product measurements, they should be read as follows:

Cold water inletA, mmR1¼ "/ 450
Y, mmmG½ "/ 232

A is shown in the previous diagram. "R1¼" and "G½" are the measure in inches of the opening. "R" is male and "G" is female. The measurements in inches indicate the distance between the floor and the opening.
