Holy cow, that's a lot of firewood! Even if you mean "face cords" (4'x8'x18") that's still like 17 full cords. I generally get by on a half-dozen (full) cords a winter, granted the house is very well insulated. If you don't mind my asking, what sort of building are you heating, and where located? I'm impressed...
Central Coast of California. Heating two story house, 2 fireplaces.
No, these are “real” cords and there are 80 of them. I usually go through 3 or 4 a year, sometimes more. We took a lot of oaks out due to the fire danger, and the stockpile of cordwood is the result.
