20,000 gal pool in LA (near LAX) with Raypack 2100 heater. looking to swim year round, but the cost of heating is $500+/month for heating Thursday-Sunday, to 85*f. From my research it looks like a heat pump would pay for itself in savings after less than 2 years. We do use a cover at night and when not swimming.
1. Can I install a heat pump IN ADDITION to the gas heater? in line, with the pump after the gas? I don't see why not, but I'm a newbie.
2. Recommendations for heat pumps? I'm leaning toward the Raypack 8350ti. too big? too small? our day temps are 65-75 winter, 70-80 summer, night temps 50-55 winter, 60-65 summer. wind 0-10 knots.
3. Recommendations for installers in LA?
Any info is appreciated.
