My 28 ft round above ground pool is at a weekend home. We are not there during the week to take off solar heater during the day. I was advised not to get a solar heater due to possible algae buildup since a blanket would impair gas exchange.
I want to heat the water some (water can be a little chilly for my taste). The house has no gas or propane. It is all electric. Which would you choose: solar or electric heat pump after considering the following:
1. I do not really get swimming till may and will end by September when the kids start school again.
2. Only weekend use of the pool
3. No solar blanket
If solar, which one? I have looked at Vortex but they are quite expensive and need more panels (per their calculator). If fafco, they recommend less panels but only heat up to 10 degrees. I would prefer to mount on the roof.
Any help/suggestion that you all can offer is much appreciated.
