Hi all, I have a terrible time with primary air coming from the top of a stove. The draft setting that keeps the stove at a reasonable temp during the gas stage of a burn does not allow for complete burning of the wood in a reasonable time, in my experience. Once the charcoal stage begins, I need to open the damper partway or else I will have a large pile of coals that persists for 24-36 hours (emitting heat at a rate far too low for effective heating). This means that I can never leave the stove alone for more than 3 hours after loading if I want optimal heating. I'm omitting the name of my stove for now because I believe, after 3 years of use, that the airwash system of primary air is the problem, and I can't seem to find any new stoves on the market that don't use this technique and boast about it. In my experience, it doesn't even keep the glass clean anyway! What keeps the glass clean is high temperature, which my stove company seems to disapprove of most strongly. I did find that Quadra-fire stoves use bottom primary air, but I won't consider that company after some of the reviews I read. Anybody know of a well-built stove that directs primary air at the coalbed?
