Question: I have a Harman Exception woodstove. We use the stove to heat 1500 square foot and it has been doing a wonderful job. I have always burned oak wood that I take from some property in western Maryland. Recently I was offered all of the soft maple I can cut down. My question is this: I have always and only burned oak in the past and I don't know much about maple.I know that it will not burn as hot as oak. What I do not know is if it will burn clean. I don't want to use it if it will clog the chimney. Is it safe? Answer: Any type of maple is fine. If's it's soft maple, then it may not burn as long or produce as much heat per cubic foot...but, if seasoned and dry, will burn clean.
