Wood Duck said:You have to read up on the new 'EPA' stoves. Newer stoves burn the wood more completely through 'secondary combustion' and there are two types - cat and non-cat. Each type has advocates, but I think from what I read here, that cat stoves are better for long, low burns. With a small home, you could put in a medium-sized cat stove and, I think, turn it down low for long burns that wouldn't roast you out of the house but would last a long time. A large firebox (the place where the wood goes) would be good for a home that is relying mostly on wood for heat. however, I would not build a home with wood heat only because I would want options, such as the option to sometimes leave the house in the winter and not have to worry about it freezing.
Wood Duck, perhaps you have misunderstood how a cat stove operates. You are correct with the long burns but mistaken on the low burns. For example, if we fill our firebox we will get a long burn and the temperature will easily go over 600 degrees on the stovetop and will stay there for quite some time. This is not a low burn.
Perhaps where the idea of a low burn comes from is that while we are getting this big amount of heat we do not have a roaring fire; the cat is working at burning off the smoke. Sometimes we have the "ghost flame," or the beautiful rolling flame at the top of the stove (off the wood) and at other times we will only have some red coals and still at other times not even a hint of a red coal. Yet, we get lots of heat.
