    Great, Gary. Everyone should bookmark that and use when talking to customers about different fuels.

    Right now for 35 out, it says my 80% furnace would cost $13.25 for a million BTUs or my heat pump would cost $4.10 for the same heat. Guess what's on

    For heat pump, find out COP and use that in %. For COP of 3 which I'd estimate I'm at with this outdoor temp, I put 300%.

    Here's another calculator at http://64.226.150.132/hydronic/hea/FuelCalc.htm that even lists the btu's for a kilowatt of electricity, a therm of natural gas, a gallon of propane and a gallon of #2 fueloil. Also says the calculator is available at http://www.hydronicnetwork.net/ for use on a laptop.

    Good links Mech
    The way we build has a greater impact on our comfort, energy consumption and IAQ than any HVAC system we install.
