Cover it with an insulated top when not in use. Your pool is colder than ambient because the top surface is constantly evaporating, leaving behind the slower moving molecules.
A solar heater would work better (if you have sun) because it will absorb more energy than ambiant air convected over the same area. And you would need a fan for a heatsink if its wasn't windy. http://www.amazon.com/SmartPool-SunHeater-Above-Ground-Pools/dp/B000RQ0RDC http://www.amazon.com/SmartPool-SunHeater-Above-Ground-Pools...
A way for you to test it would be to do it on a small scale - maybe buy some copper tube and circulate an aquarium with the water filter pump.

- ramchip 16y agoYou could also buy a regular pool heat pump and stick it in your house: http://www.halfbakery.com/idea/Pool_20Heat_20Sink http://www.halfbakery.com/idea/Pool_20Heat_20Sink

- tocomment 16y agoGood points. I was hoping to come up with something easier to use than a cover, and possibly cheaper.
- starpilot 16y agoCovering an in-ground pool is a huge hassle.
- nitrogen 16y agoIt's a lot easier if you build a motorized cover in from the start.
