We have heated exclusively with wood for 20 seasons. Small one level house, 1700 square feet. Heated with a Kent (New Zealand, no longer available stateside), in Ohio winters, house fairly exposed, but we do have 6" insulation sidewalls and 10-12" in the attic. "Typical" use is 3.5-4 cords. Once used a hair over 5, and the least was a little over 2. Bear in mind we have a fairly open floor plan, our house is easier to heat than the typical house of the same size. And this is fairly accurate as we stack/store our wood in by the cord under a wing.
Also heat a 20x30 shop in the barn with wood x 20 years. Used several asstd. old stoves, bought a QuadraFire 5 years ago. I have to keep the shop from freezing even when not using it, as we store "freezeable" things in there....so I usually build a small fire in there each evening. That IS INCLUDED in the wood usage above. I estimate I use a cord in the shop. While the Kent is one of the most efficient stoves I have ever seen (and 20 years ago Consumer Reports rated it light years ahead of other stoves), the QuadraFire is impressive. It will not shut down as low as the Kent, but it heats quickly and puts out an amazing amount of heat for the amount of wood it consumes.
