The GREŃ EG-HOLZ boiler is a device which uses the principle of dry pyrolytic wood distillation. During combustion in a high temperature and limited oxygen supply, wood gas is produced, which is then directed to the lower part of the boiler, through a ceramic burner nozzle. Thanks to this solution, the energy stored in the dry, seasoned wood is fully released.

Thanks to this solution, the energy stored in the dry, seasoned wood is fully released.
The EG-HOLZ boiler has been designed according to the latest trends and technology.
The device is equipped with a very large loading chamber (220l) which allows to burn pieces of wood as large as 50cm in length.
Thanks to such a big loading chamber - the biggest on the market for this power range - the frequency of refuelling is extended, which greatly improves maintenance simplicity and customer comfort. The operating time of the boiler with a fully loaded tank is 72 hours.
The HOLZ boiler is factory-equipped with an advanced heat exchanger cleaning system. The system facilitates easy cleaning of the heat exchanger from the outside.
Boiler operation is optimized by a suck fan which comes as standard. One of the advantages is that the boiler can be started without any problems with a cold chimney. Stepless fan control allows to control the combustion process and adjust the power to the needs of the building.
