Advantages

Minimum emissions

Emission class 5 and minimum toxic emissions.

Small boiler size

Thanks to clever design, the boiler can be placed in smaller spaces.

Cost Saving

The solid fuel boiler’s high efficiency saves heating costs.

Control unit

The electronic control unit controls the entire heating system.

The intelligent wood boiler combines classic heating with modern technology that guarantee high efficiency.

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
