Wood Boiler Gasification in action ... The Ulitimate!

Models: Konigsspitze, Arunda and Wilder Kaiser Specifications:

All models are available as a free-standing model and as an insert. This hydronic heater has a 30/70 heat distribution ratio. This means that around 30% of the rated heat output is radiated into the room where the unit is installed and around 70% of the rated heat output goes to the water.
