That was my thought as well. Since we always need heat for the pool it isn't an issue. I just use the heat pumps for cooling the house as necessary and any additional heat that ends up in the pool offsets the gas heater. I did find about 20 hours a day or more will increase my pool temp. Although it is pretty rare I needed that much cooling. In those cases the central AC would just pick up the slack. Again it is a win-win.

I actually run off peak rates so I typically run the heat pumps and pool pumps off peak unless it is really warm. Our modest solar array picks up about 1/2 the loading of I do run on peak.
