After the last several months of propane use and it's certain rising costs (more than doubled in the past year) I've decided to look into getting most of my home (& hopefully hot water) heat from some combination using wood burning. Since I live in the woods I have an unending sustainable fire wood source. Just never got around to putting any fireplaces in my home. I've been looking at wood burning furnaces and wood stoves but I'm not sure which way to go. 1) Wood burning furnace boiler which sends heated water into my home to a heat exchanger that will then use my existing furnace to move the heated air. This would also heat water in my hot water tank. 2) Wood burning furnace that sends hot air into my home for my existing furnace to move. Leave hot water alone (heat with propane). 3) Wood burning stove. Leave propane furnace & water heater alone. Anyone have experience or expertise in this area? Suggestions much appreciated.
