How fast does a propane heater warm a 15k gallon pool compared to solar? I know a lot depends on heater or panel size, assume sized nominally. Just wondering if I can get by without a cover. Say heat from 8 am to noon and swim in the afternoon 2 or 3 times a week.
I'm actually considering replacing a dual fuel a/c with a heat pump because of high the of propane to heat the house. Don't want to make the mistake of buying a propane heater just to regret it 1 year later. House has a 3/4" propane line at the pump area. Pool 50% shade.
