This propane has gotten way out of hand like everything else anymore. We use a forced air wood furnace in the basement. I also have natural gas. As many ice storms as we have had on the last 25 or so years here on northeast Arkansas, I wouldn't be without wood. Not a big fan of heat pumps, no matter how efficient they get them, they still won't feel as warm as wood. Plus, it's something else to worry about putting power too. If I built a new house, I would design it around a centrally placed wood heat source. My house is built like that now, even of we loose power the furnace still will hear the house. LUTT
