New Heater Install - Efficiency Question

[l1ltaral1l]

Hi all,

Our new heater was installed yesterday (all info should be in my sig). It was turned on at approx 2pm. Water temp was 63 deg. One degree change (64) at 4pm. At 4pm, I put the solar cover on. Left the pump/heater running all night. This morning, temp is 63. The low temp weather wise for us was about 48-50deg last night. Does this seem normal? I know heat pumps don’t do the job quickly, but I thought it would have at least done something. But maybe I’m just unaware of how much the ambient temp outside effects it’s efficiency. I did troubleshoot a bit - flow seems fine, skimmers were cleaned and there is water leaking out of the bottom.

Thanks so much!

This is about right heat pumps generally will not keep up with nightly losses if the temps drop too low. And in the 40s they don't produce any heat. I think I'd just run it during the day for now.

They are not very efficient below 55 from what I have read. I schedule mine to run during the heat of the day.

I set the bulk of my heat pump pools with vs pumps at 7 pm so that the pump ramps down to a speed where the heat pump flo switch comes on and I ramp the speed up again at 9am.

Update: pool is at 75! I was just being impatient and not understanding. So I think we are good now. Solar cover is on, and the heater will turn off from 8p-8a with the pool pump.

Side question: is the filter pressure increased when a heater is added? I noticed ours is up a bit, even after backwashing.

Answered my question (it's normal!)
