So I was hoping someone on here could give me their opinion on my situation. As the weather is getting warmer here in Texas, I decided to turn on my Pentair heat pump for my inground pool. The pump does its initial warmup and then I hear the pump kick on, except no warm water is coming out of the jets. Since my heater is still under warranty, I had Pentair send out someone to take a look. Unfortunately I was not home when they came to look at it. All they did was turn on the unit, wait for the pump to kick on and then tell me that there is nothing wrong with it and that I might need to pay for them to come out since my unit was actually functioning. I spoke to the tech manager and I told him that there is still no warm water coming out of the jets. He told me that I would not be able to feel the difference in the water temperature when the heater was running. I told him that was incorrect as all last year when we ran the heater, people would stand in front of the jets to feel the warm water coming out. He then said that something was wrong with my unit last year as that should not happen and that this year my heater is running normally. I am no expert here, but I do not understand how a heater can heat the pool without putting water in the pool that is warmer than the temperature of the pool. The mgr then told me to wait until the weather warms up some more and then check the heater again. Pool water temperature was 70 and outside air around 75 yesterday and I could still not feel warm water coming out. Sorry for the long post, but just very frustrated and I guess confused.
