I have a tri level with a Buck 81 insert downstairs and a Brunco Hearthglow on the mid level. The Buck works great except getting the heat from downstairs to upper levels is tough. The Brunco puts out lots of heat but goes thru 3 times as much wood as the Buck and burns 3 times as fast. I was thinking about replacing the Brunco. I wish I could get another Buck 81 but I guess they don't make them anymore. Any recommendations? I only need to heat 1600 sq ft. I know there are tax credits thru this year so that would help.
