It will run you out of the house if you aren't careful, but no matter what we do we can't push the heat downstairs. i can run ceiling fans up stairs and down but it just doesn't heat the downstairs.
We have a propane stove on the first floor of our cabin. Fairly certain it is the biggest propane stove you can buy. The upstairs is what I would call a 3/4 loft. 1/4 of the upper floor is open above the living/main room of the cabin where the stove is. This past Winter in the cabin we were running the propane stove full blast and on the really cold (0 degree) windy days we had a hard time keeping the bottom floor above 60 degrees. The upstairs would be 80 degrees! That's with two big ceiling fans running full tilt as well. IMO, the ONLY way you could force hot air downstairs is with duct work.
I really like Snrub's direction of putting the stove outside. That solves LOTS of issues IMO. I had planned on adding one of these Iowa made stoves to our cabin at some point. I would just duct the heat into the crawl space of the cabin and cut in vents in the appropriate places.
