Easy Operation

  • The wood gasification boiler has a large hopper so that you don't have to refill very often.
  • It's designed for burning large pieces of wood and has low fuel consumption.
  • The boiler can be regulated by an outdoor sensor to compensate for temperature differences, ensuring a stable household temperature.
  • The boiler includes a cooling unit.
  • It's possible to add an electric coil for electric heating.

Economic operation

  • Efficiency up to 90.2%.
  • Low fuel and electricity consumption.
  • The added extraction ventilator ensures more efficient combustion and a minimum of ash.
  • It belongs to emission class 4 and meets ecodesign conditions.

Small size

  • It's also suitable for small boiler rooms with low ceilings.
  • Boilers with an output of 16 kW and 20 kW can also fit through a 60 cm width.

Boilers long service life

  • The exchanger’s 5-mm sheet thickness guarantees its long service life.
  • Warranty 5 years
