Like alot of folks I have been looking for a way to reduce my use of heating oil. Does anyone have any experience with the Hahsa outside wood furnace?
My neighbor saw one once and said it is a DIY project that involves a plate steel fire brick lined furnace housed in cement block encloser, the cement block is insulated on the inside and between the styrofoam insulation and the furnace, water pipes are laid then the whole thing is packed with alot of sand.
I'd appreciate any feed back if anyone has any knowledge of this unit.
