I was searching for any threads on best times to run a heat pump to maintain temperature... I did not find any.
I don't want to run the pump 24 hours. I know that the most efficient heating time is when the outside temp is highest... so, my real question comes down to whether it is cheaper to keep the heater off at night and just let it run again after about 10am when the outside air temp is creeping back up... or should I allow it to come on a couple times at night for an hour or so to keep temp from dropping too far... curious is anyone has done any analysis on what works out to be best for run time and cost. If you have a heat pump, when do you run it and for how long, to maintain pool temp for afternoon and evening swimming?
