While I'm in a heating frame of mind...another question. Our home's heating system is an oil furnace with a boiler and baseboard hot water radiators. I'd never heard of this till we were house shopping, and people told me it was great for efficiency, comfortable humidity levels, allergies, etc. We don't have a problem with it either, except that sometimes I wonder if it's possible to adjust how much heat goes where, and how. But my real question is about the oil furnace. It's old and will probably need to be replaced soon. I don't particularly want another oil furnace - it's such a hassle getting the tanker truck out to fill it, you worry about leaks, it smells, and if you run out, hey, no heat. Electric? Can be expensive, and if the grid goes down, hey, no heat. We don't have natural gas lines. I'm seriously thinking about a wood stove to heat the boiler. Anybody used a wood stove made for this particular type of system? I'm told they do exist.
