To be honest I don't know if I could or not, I haven't tried. I usually start a wood fire to take the chill off if need be until the the outside temperature drops. I think if I couldn't it'd be because of something I did wrong. Like I have said, I by no means think this is the perfect stove, but I've learned enough from all the folks here to make it work effectively. The main thing I think is maintaining a good draft, if you have a good draft and fuel it should burn.
At this time I have the hand damper closed 80% and the little door on the draft fan(fan not running) is 90% closed. Before last week, I was running the door on the draft fan(fan not running) about 75% closed. When I got home I had good hot coals in the middle but the front and back were nearly burnt out. It had me scratching my head for a bit. Same thing at night. I didn't remember having this problem last year and like a dumby I didn't mark the location on the draft door. I did some more reading here and decided to cut the draft way down on the door, figuring if I was burning up all my fuel it was getting too much air. I'm not home during the day so I had no way to judge what was going wrong, I could only see the results. So far it's working for me.
I have the distribution fans wired to the cheap thermostat that came with the stove. I think the dead band is about 10 degrees. I will be taking care of that right shortly. I have it set on 70 and so far the fan doesn't run over night and it's 68 or so when I get up. I kick the stat on and go down and open the ash door. By the time I'm out of the shower it's 75, and it's ready for a reload.
Yes it would be nice to have a Cadillac, but I'm a Chevy truck man myself.
