In Iowa, last winter was the worst I've ever been around in decades, my wood doctor eat firewood by the truck load, we lost count after fifty cords but I do know we burned my entire years supply plus this winters supply as well, heating a 125 year old two story house that's about 2000 square feet, and a shop that's about 2700 square feet, but has 20 foot ceilings in it.
The wind never quit blowing all winter long, and the blower motor on the boiler never shut off for weeks at a time, we had issues but hopefully have them worked out now, time will tell.
