So, first year with my pool. Have had the pool open for a little over a month and the weather has been really erratic. I am trying to figure out exactly when it makes sense to use the heat-pump for heat vs. propane heater.
Everyone says, that if you want heat quick, use the propane heater (I get about 1 degree/hour with the propane heater). But we also have a heat pump, and with propane at around $3/gallon, I want to use the heat pump when it makes the most sense.
Clearly, if I am just looking to maintain my heat (lets say 84) during the warm summer months, the heat pump is the way to go. But how about when the temperature varies between 58-72 on a daily basis (with a few days hitting 80 at the peak). Is it a waste to use the heat pump? I tried running it for several hours (5) with 0 heat gain when it was 76 in the pool and about 74 outside.
Does the heat pump do ANYTHING if the pool temp is higher then the air temp?
