Just curious as we have a 110,000 BTU Heat Pro on a 16,000 gallon pool.
The water temp right now in unheated pools is 69F. This heat pump has the water at 87F but owner wants the temp to be 91F but we are having problems getting up there. The heat pump is not exposed to sunlight and is in a shaded area which I think makes a difference. We run the heater 23 3/4 hrs per day. almost 24/7 but still can't get the temp up. This is the first time since we installed it we had this problem. Right now the air temp is 79F but this weekend it was much lower in the 60's.
I have switched over to spa mode hoping this will help.
anyone can spread some light on this? Many thanks!
