We have an above ground 18X33 pool coming soon. The pool holds about 14,000 gallons. We are snow birds and will use the pool from late August to early May. I guess my first question is whether we need a heater at all. There are some nice plus 70 degree sunny days in the "winter" here when we would like to use the pool. From what I've read it appears that a heat pump might do the job for us. If so how big a heat pump do we need? Not sure which direction the house faces for solar panel use. We use propane to heat our house in Pa in the winter and there is alot of price gouging up there so my inclination is to stay away from propane not to mention that it costs almost twice as much in Florida ! . There is no natural gas here.
