I need a pool heater!

But I've NEVER heard of a heat pump that used THAT as the source of heat! Wow--that's a great idea, if it can be made to work--a sufficiently large heatpump would work no matter HOW cold it got.

I'm in Central PA and I installed a Geothermal Heat pump for my home back in 1992. BELIEVE THIS!! It paid for itself in 4 years compared to the baseboard electric I had been using. There are Geothermal heat pumps for pool applications. If you are even thinking of a heater in PA I would recommend you look at Geothermal. The size is still determined by surface area and the temperature differential at which you intend to use it.

One other thing I have to mention is whether you asked yourself this question. "Am I going to use the pool when the air temperature is low?"

My wife and I don't go near the pool unless the air temp is above 75 - 80degrees even if the water is the same or higher. Maybe I'm chicken but it's cold out there when your all wet!!:eek: Any heater is expensive if you don't swim when the air is cool.
