I have a question regarding different ways to heat an old house. My husband and I inherited a post-civilwar era farmhouse. The heating system in place now are 3 HUGE potbellied woodstoves. There is only a very small root cellar under the middle part of the house. My question is this.. what other options for heating would work here? We currently have a coal stove in the temporary home we're living in (which I would rather not have in the other house). Any suggestions would be appreciated and taken into serious consideration. The house is 2-stories, and about 2000 sq ft. Putting in a larger basement isn't an option, but there are numerous small rooms that need to be heated.
