I went from natural gas to geotherm electric, with a 3000 sf house and 3 kids our home is totally electric, the largest bill we had this year was $170, that was for all utilities in one payment. I reccomend the water furnace to anyone who has the acreage for the ground loop, or better yet if they have access to a pond then the water loop is the best (thats what we have).
How much did it cost you to make the initial investment to get into that deal? Send me a freepmail and tell me about it ;) Wanna get away from my lp propane if I can.
