You live in the same place I visited, right? You shouldn't have trouble heating the joint with a Woodburner. We had one at our first house and was the bomb diggity. Just keep the kids away from it, my brother and I were always melting things on top of it.

Its a steel box with a door, cant be too expensive, $500~. See if Tinman can make you one.
If you wanna go oldschool, you can put a skillet on top and cook on it.
Oh, and you'll need a flue cleaning kit, do it at least once a year. It's fun, and an excuse to get on your roof. Its basicaly a big pipe cleaner on an extending rod.
