The answer to this question may be that everything is fine, and I just don't understand the detailed workings of how a heat pump heats, but is about a 5 degree difference in pool water vs return jet water temp typical, or could something be wrong with my heat pump? I just fired it up today; first time this season to be sure all is well. Water temp is about 55 or so. Water temp out of the returns is about 60. I recall last summer, feeling nice warm water coming out of the jets, but granted the pool was a lot warmer...does it only pump out water about 5 degrees warmer than the pool? Air temp right now is 72.
I see no error codes, and it looks like it's working just fine...so really not sure.
