I am in the process of building a pool in NJ, but haven't picked my PB yet. My pool will be about 1200 square feet, have a variable speed pump (probably Jandy), a Aqua Comfort AC-150 Heat Pump, a Polaris 280 with 3/4 booster, a Rockwall and Grotto (inside Grotto there will be 6 Jacuzzi jets and blower), 2 Laminar Jets, 2 LED Bubblers in a sunshelf, 2 Ledlights in pool and one in Grotto, Jandy PDA P8 remote control, 90% Quartz finish, Zodiac SWF 185 GMP waterfall pump, Levelor K1100 autofill, and Autopilot Digital SWG. My pool will have 2 skimmers and (as of now) 5 returns. Most piping is 3 inch.
I would like to keep the pool at a constant temperature from June through August (maybe 85 or 87) and keep it as high if possible in May and September. I know from all the threads that a gas pump will work better in May and September but am curious how much more it would cost to run a gas heater than the heat pump in June through August if I want to keep a constant temperature.
