Hmmmm.....My mother has a HUGE wood stove. She uses wood and wood only. Her house is on the CT registry of old ass houses,(literally old, like 200 years) and she doesn't use more than 6.
My house is not "HUGE", it ain't even "big" (100-year-old, single story, 1104 sq ft above grade)... 6 cord might heat it during a mild winter (probably not), 8 cord is typical, last year it was something over 10 cord. It doesn't seem to matter what type of appliance I'm burning the wood in, it flat takes somewhere between 7 and 9 cord to heat most years. If'n your mother is heating a 200-year-old house with 6 cord or less... well... her winters must be a lot milder than ours.
Now, I know the Seneca, IL area where hupte lives, and they typically don't see the extremes we do, but... I'm seeing an OWB and a 2-story house in his pictures, and he says he's heating a shop also. If I used over 10 cord last year with an indoor forced air furnace, and he's heating a 2-story home (twice the above grade sq footage), plus a shop the size of my home (1200 sq ft) with an OWB... 25 cord last year don't sound out'a line at all.
