Even though our house is 6,000 square feet, when you start subtracting the closed off space like the unused third floor and basement, and the unused back rooms on the first floor, the actual downstairs is only 1,000 square feet. It sounds like you agree that the 300 square foot living room would get cooked by the Oslo. I'm surprised to hear you recommend the F100. I'm sure that's adequate for the living room, but would that mean giving up on heating the rest of the house? Would the hearthstone not heat us out to much because of the soapstone?
