Question about Aquacal HEAT PUMP 120,000 BTU H135 -

1 Answer

I have a AquaCal Heatwave H125C-A Pool Heater. The Heater is working in that the power is going on and the air is blowing- although- the air is usually colder than the outside air and now it is only air temperature and not heating the pool. I am in South Florida. Does anyone have an idea of what could be wrong with the pool heater?

    the barb split and broke off what looks like a nut which is connected to the top of the heat exchanger.

Sounds like your compressor is not running. After your fan goes on in one to five minutes you should hear the compressor kick in. If it does this and then kicks out again it can be something as simple as water flow and you can adjust the valves to get more or less flow to keep it running. If not you probally need a repairman. It is ether your compressor or the capicators that start the compressor and this is all high voltage. Good luck.

I have an aquacal heatwave 155. The pump runs and red light indicates it is heating, but the water is coming out cold. What's wrong ?

if heater is calling for heat and running is heater lit? if so water is prbably going through heater so fast it isnt heating to your feel you might want to install a bypass valve and only let 50 percent of water through see if that works

My panel is blank, breaker tests okay...unit seems as though not getting power...any thoughts?

is this a pool heater? if so check voltage from transformer to panel.
if you have 24 to 30 volts it is likely a bad panel

AquaCal Model 120 AHDEBNC message on panel wont clear. Message is FLO. There is water flowing thru the heater and the filter is clean

If you have a by-pass, (This will be a pipe that runns in between the in and out pipes on the heater) The valve must be almost closed in order to get enough volume through the heater to get it to run.
Make sure that heater has enough time to respond to this adjustment. It will take up to five minutes to start.
