Why is my Zodiac Heat Pump working but the water temperature not increasing?
- CCurtis BryantAug 4, 2025
The water temperature may not increase because the operating mode isn't powerful enough. Try switching to 'Boost' mode and setting the filtration to 24/24 manual while the temperature rises. Also, the heat pump might not be capturing enough calories due to a dirty evaporator, so clean it. Ensure the external environment isn't hindering the heat pump and that the heat pump is the right size for your pool and its environment. Installing a heat-insulated cover on your pool can also help.
