Single story 3 bedroom in moderate winters Oregon. 1st couple of years I burned 4 cords. I'd just put up 8 cords Doug Fir/Hemlock and 2 more of Oak. Had to re-roof, it turned into a re-sheet so while I had it open I added 6" batts over an inch or 2 of blow-in insulation. That winter I cut my firewood use 50%. A good sized tree is about a cord.
