I'm not sure where you came up with $150-$200 per month on a heat pump, but that number is far too high. Here in Florida, my pool is small (7K gallons), and my heating costs run from $10 to a max of $40 per month during the coldest months. When I was in Georgia, my pool was 18K gallons, and heating costs were between $20-$60 per month during late fall (we closed end of November) and early spring (opened 1st of March). In both cases we had a 144K btu heat pump. We used a solar cover at night during cold periods to reduce heat loss over night, and programmed the heater to turn on at 11am and heat the pool to 88 degrees.
