That sounds a little low, but I guess they are pine numbers. Still, 2.75cf firebox on that stove.
He didn't eat to give bs numbers. So he was being ultra conservative. That's with cutting down, bucking, splitting with in a few days. No seasoning, just bare, standing, better kill, lodge pole.
I burn my princess insert when it's 60 degrees outside. These stoves crank WAY down, and the more you turn 'em down the less wood you use. You do need reasonably good draft to burn very low, though.
That is what I'm looking for. Part of my home had an upstairs. Terrible layout, and cold. I am going to open up a 221/2 inch square hole above the hearth (within 5 feet) and make a homemade register. I will have great draft. So I plan on flooding alot of that heat up stairs which will not stay in the home too long anyway.
