I know this has probably been asked a lot but..... How many cords of wood would you guess we will need? We are in Central Illinois, 2000 sq ft single story home with crawlspace. Built last year, 6inch walls 12 inches cellulose in attic, very open floor plan, stove pretty much in exact middle of home. Kitchen Queen 480 is stove. Last year in old 2 story farm house we kept furnace on 65, we don't like it hot. haha. Any advise or tips would be great. Thanks
