Ten cords! good grief, you should build your house IN the woodlot and just set fire to a tree each week!
10 cords. Depends if its a face cord (18+” wide X 4ft high X 8ft long) or a full cord 4H X 4W X 8ft long. Good black oak cured after two years is hard to come by and if not selective on whom you buy it from. You can get green stuff which burns slower at a lower heat rate and does creosote up.
Use an 40 year old Ashley accepts up to 3- 2ft X 10” logs. Getting wood that size 2ft long is hard to come by. Most sell a 18’w face cord around here, Friendship, in central Wisconsin for $50-60 bucks.
Using face cord measurements I’ll go through about 8-10 face cords. We start to get 40 below over here begining around Christmas lasting until the middle of February sometimes into March.
I;m also supplemented by a propane furnace if not wood stove is not in use.
We added one of those outdoor woodstoves to our last house...a 1912 parsonage that had been remodeled and insulated, very similar to a large farmhouse. We went through 14+ cords/winter, had them delivered by semi in 8’ logs, all oak, that I needed to buck. We paid $50/cord. But was I’m getting too old for the annual work involved. 14 cords is a depressingly large pile of logs to buck.
