We installed a new pool this summer. It's been brutally hot and my water averages about 88 degrees so far. No need to use my Thermaflo yet. Someone told me that heat pumps require you to get a solar cover also. My PB never said that to me. I have a funky free form pool so a cover would be a challenge and also I don't like them. Any thoughts of if this is true? I had a gas option as my house is heated with propane and this will make me angry if so.
