I have a 9500gal above ground pool with one 2'x20' solar panel. Unfortunately both the pool and the heater get more shade than ideal, but that's what my site gives me. A couple of nights ago I was doing my evening pool test/treat routine when the air conditioner kicked on, and with it my thinking cap. "If I could take the heat that comes out of the house via A/C and put it in the pool water I'd really have something", I thought. Has anyone done this? I've thought of three potential approaches;
-Place a radiator over the A/C fan outlet so the warm condensor exhaust can warm the water as it's pumped through. Potentially this could restrict airflow enough to compromise efficiency of the A/C unit.
-Coil plastic tubing around the refrigerant hot line, wrap the whole thing in water pipe insulation, pump pool water through. There may not be a lot of heat gained through this method.
-Pump pool water through some sort of low pressure vessel, maybe an old filter housing. Place a copper coil inside, pump refrigerant through on the way to the condensor. This one makes me nervous because it means tinkering with the A/C itself, but probably has the best potential for positive results and could actually make the unit more efficient because the heat transfer to water would be very good.
