I have a 27' AG salt water pool (roughly 17,000 US gallons). Last night I installed my 110,000 BTU heat pump. The pool was 70f and I let it run all night (with solar blanket on, ambient temperature around 55f) and the temperature only raised to 71f this morning. I was expecting at least 3f or 4f increase. Is this normal?
I checked using an infrared camera and the outlet is 3f-4f higher than the inlet
