So... I didn't get a chance to post during the coldest part of February, and I wasn't around the house much in the evenings anyways, but we did get a few weeks where the outside temperature was around -15F (say -22C) at night.

When I ran two medium sized fires a day the outside of the heater stayed a lot warmer and seemed to keep the house around 60F when the outside temp was -15. I think if I had been around enough to split more firewood and get 40-50 pounds of wood in each fire (vs. the 25-30 pounds I normally burn) it *probably* would have kept the house comfortable on two fires a day.

It's warming up now so I guess I won't know for sure until next winter.
