Have you ever had a wood stove or used one before? What about wood supply? I used to use a wood stove for several years but I’m not the one who put it in. You have to be careful about creosote buildup in the chimney. And different kinds of wood burn differently. I used to burn maple and birch mainly. I know nothing about certification. Maybe we didn’t have to do it then.
Some people around here make a stove out of a 55 gallon drum and put sand in the bottom. I think there is a kit at Lehman’s for it. I’ve seen some soapstone stoves that were gorgeous but expensive. Mine was cast iron. We had a stove board under it and I believe it had asbestos under the metal- don’t even know if you could find that now. I will leave the technical questions to someone else.
