Tropical heat pump

[newpoo]

Thanks for the reply's guys. Carl after your post I took the hose out and tried to clean the coils a bit. I then let it run another 6 hrs , but still no temp change.
I had already cleaned the filter and the water flow is good and strong. I live in St. Petersburg florida so daytime temps are around 84 deg and night time temps are around 74 deg. The heater ran for 15hrs straight than I turned off cleaned the filter and ran it another 13 hrs with no change. I have heated the pool many times before and after 15 hrs, even in winter, the temp would be well over 80 deg.
The unit is a TropiCal T-115B-A
BTU/KW 94000/27.55
I do not have a cover but plan to get one soon so any advice on that matter would also be much appreciated.

Can you feel any warmth at the returns when the heat pump is on? At an outside temp of 84 degrees your heat pump should be providing quite a few degrees of warmth to the returning water.

Sorry to bump an old post up, but before I have to call out the pool people I thought I would ask for any more ideas for my heater problem. I ran my heater almost 30 hrs and I now own a cover. There was an increase of 2 degrees(most likely from the cover).

I have an AquaCal Heatwave Icebreaker and the manual DOES recommend yearly maintenance to keep the unit running at top efficiency. Perhaps it's time to bite the bullet and get the unit serviced. Not really that different from a central AC unit. These really need yearly service also to keep them ruunnig properly.

You can also check the air temperature away from the heat pump. Then compare the air temperature over the discharge air, moving it around to the coolest discharge air. You should get 9 - 12 degrees difference in the air temps.
Water temperature split if tested at the skimmer and the closest return line should be about 3-5 degrees. If you do not have this, you have problems with the unit. How old is your system? You many have warranty coverage on it still.
Are there any red lights on the control panel?
