My point was that the house is a limited heat source, and once you start supplementing from a second source, no money saved. I doubt converting would be cost effective.

I like the idea in principle, "free heat!" I just don't think a combination A/C-Pool heater is practical.

Perhaps a lower cost idea such as running a heat exchanger above the A/C unit to catch the exhausted heat. A basic example being, use an old car radiator and a small pump, wired to the A/C fan, to circulate water when unit is running? Something simple like that.
