I have propane heat, one gallon of propane cost $1.50 and has 92,000 btu, furnace is just better than 90% efficent so I get about 83,000 btu of heat for $1.50, at 12(using the above cost, mine's closer to 15) cents a KWH, $1.50 buys 12.5 kwhs or (1 kwh = 3412 btu) or 42650 btu, about half the heat from electricity as from propane. Electric heat would cost me 2x as much per month.


Natural gas is way better, it's usually sold by the therm I think, which is 1,000,000 btus, last time I look it was about $4-5 a therm. one therm = 293 kwh which would cost $35 in electricity. Electric heat would cost 7-8x as much per month. (I don't and have never had natural gas so not sure on these numbers)

EDIT: forgot to factor in 90% efficient furnace with Natural Gas so closer to 1/6-1/7the cost of resistant electric heating.
