Been a week now since I put a fire in er. And I sure have learned alot. 1st off, the only difference between the basement stove and this one is 6" in barrel length. Basement stove (30") is on a 6" Class A 35'+6' of stove pipe and 24" is on a 35' air cooled 8" (for now) with 2' of stove pipe. The basement stove takes nearly a full hr from light off to cruising temp. The 24" is a mere 30mins or less and that's if I'm careful and capture it before it goes nuclear. The 30" has always had unusually cool stove pipe temps, the 24" is exact opposite. Very hard to keep those temps below 500. Again I have to watch the first few minutes closely and close off the primary early. Still later in the burn cycle they can climb to 600+. Both stoves are operated daily with dampers fully closed at all times and primary full shut on the 24" at all times. I have been using the 24" with kid gloves only loading a few small splits at a time to help keep temps down. What I'm taking from all this is a stoves environment means everything to how it performs. The room this stove sits in has an 18' ceiling. It is still doing a very nice job heating the first floor and the second floor.
