I live in a geodesic dome and I have a free-standing wood-burning stove as a supplemental heat source in my master bedroom which overlooks the living room.

It is capable of heating the entire house by itself, but I only use it like two or three times a year.

That being said, it's often very nice to start a fire on a cold day and have a girl over and have the fire. It's a good excuse to not be wearing any clothes.
