I usually (say on a average winter) go through 6 to 7 cord, last year being an exception to the rule. I may have went through 5 last year with that unusually mild winter. This year may be different, as I will have the second stove running too (Napoleon NZ3000). And then there's maple syrup season....I probably go through 7 cord just cooking that stuff, but that does NOT come from my seasoned stacks!!
We grew up putting 8 cords away every winter - we had three Fishers and a huge restored Clarion cookstove. I remember the house being very, very warm.
