The AD's on television make it seem like a "good deal". A 90% propane furnace using $3/gallon gas will give you about 84,000 BTU of heat output. (Gallon of propane is about 93,000 BTU at 90% efficient = @84,000 BTU). At $.10 per kwh electric...that same $3.00 will give you 102,390 BTU. (One kwh = 3414 BTU) Wow...save your propane...use a standard inefficient electric heater to save money or better yet...find another energy source!
