    Geo payback calc program

    Hi All,
    Was wondering if anyone knows where I could find a computer based program that would calculate the payback of a Geo system over conventional? I am looking for a program where you can input fuel costs, heating load etc.

    Thanks,

    Steve Allen

    Payback Calcs

    I would suggest that you contact the International Ground Source Heat Pump Association(IGSHPA) or Air Conditioning Contractors of America (ACCA) for their programs. These are relatively unbiased and based upon rational engineering.

    Manufacturers

    Steve, I know some of the manufacturers have design software that will do this. I have software that does just what you're describing. I was given it by a local wholesaler. I'm not sure if it it's completely unbiased but it is a good starting point none the less. The software I use is : http://www.hydroheat.com/software.htm

    Good luck, Rich L
