So I asked yesterday about the Econoburn but I have decided that it is just to expensive. I called a fairly local retailer who carries several makes and models. He asked me a few questions and turned me onto the Thermo-Control 2000 by National Stoveworks. Does anyone use one? He said that it is an indoor boiler (traditional style) that many people including himself, have in sheds or garages and heat their home. I had thought about putting it in an insulated shed but if the unit itself is not insulated I would be heating the shed which is ok but how much heat loss am I going to see? I want to still be able to efficiently heat my home. Now on the other hand if I insulate the boiler with a kit or have it done from the factory, will it still give off enough heat into the shed to keep the unit from freezing up/ maybe melt some snow off my wood? Or maybe I insulate the shed and the boiler?? Bare with me I'm new to the whole wood boiler thing. I've heated with stoves my whole life!!
