gas vs. electric heater?

Concerning using pool water to provide the heat sink for whole house A/C I don't think heating the pool water too much would be a problem. Just don't cover it at night if it gets too warm.

I was thinking in May, June or Sep the AC would not be on all that much and one would have to bring the temp from ~60* or so to 80*+. July+Aug one would not be using the pool water for the heat pump.

I guess I'm thinking more from an efficiency standpoint for house A/C as opposed to trying to extending the swimming season. Here in Northeast PA pools normally don't get too warm on their own unless we have a really hot spell. I'll take every BTU I can get to heat the pool.

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.
