When are people turning on the heaters? And to what temp? Air temps at night are cooling down to below 70 (New Jersey) I just turned on our heater to get the pool temp up after a rainy period.

I was visiting a friend and he had his heater at 90 deg

I want to keep the pool open as long as possible (late close-early open) so I turned on my heater, just waiting for the electric bill thou it is a elec heat pump...


Thanks for any input.
