- 3 years for the boiler installed with Laddomat or thermoregulator valve TV and accumulation tank

The boiler is constructed for burning black coal, brown coal and wood on the principle of generator gasifying with the use of a gas exhaust ventilator.


The ventilator automatically switches off when the fuel burns out.




  • Simple handling and cleaning
  • Revolving furnace grate - easy for ash removal
  • The secondary air is pre-heated to high temperatures
  • Three possible fuels


    This boiler must be connected to the LADDOMAT 21 or ESBE TV thermoregulation valve to achieve keeping the minimum temperature of water returning to boiler at 65°C. The temperature of water exiting the boiler must be permanently kept between 80 - 90°C.

    The default configuration of the boiler includes a cooling circuit to prevent overheating. You just need to buy the thermal release valve Watts STS 20.

    We recommend installing these boilers with accumulation tanks.
