FAQs

Why is my heat pump not heating properly or why is the heating effect poor?
  1. Undersized unit – If the heat pump model is too small for your pool, it may take much longer to heat or may not reach the desired temperature.
  2. Cold environment – Heat pump efficiency decreases in colder weather, which can reduce heating performance.
  3. Poor installation location – If the unit is installed in an area with limited airflow, it won’t be able to operate at full capacity.
  4. Incorrect plumbing – If the inlet and outlet pipes are connected in reverse, the heat pump will not be able to heat properly.
  5. No pool cover – Without a pool cover, heat loss is significant and insulation is poor, which greatly reduces heating efficiency.
Is my pool pump compatible with the heat pump?

There is minimum water flow rate required for each models.

  • 12,000BTU requires 343GPH
  • 16,000BTU requires 454GPH
  • 18,000BTU requires 528GPH
Can the heat pump be used in saltwater pools?

Yes, it is compatible. It uses a titanium heat exchanger that is corrosion-resistant.

Can it connect to WiFi?

The HEX012-HEX018 unit currently does not support WiFi control and has no mobile app currently.

Why is the product dripping water constantly?

The condensate pipe is not installed. The condensate pipe needs to be installed to ensure proper drainage and prevent water accumulation that may affect operation.

Is it necessary to install a bypass valve?

If the your pump flow rate is much higher than the heat pump’s requirement, a bypass valve can be installed. This helps manage the pool system more effectively.

What are the voltage and current requirements for the HEX012, HEX016, and HEX018?
  • HEX012: Rated voltage 115V, rated current 7.3A – plug-and-play ready.
  • HEX016: Rated voltage 115V, rated current 11.9A – plug-and-play ready.
  • HEX018: Rated voltage 115V, rated current 12.6A – plug-and-play ready.
Is it necessary to use a pool cover?

Yes, a pool cover improves heating efficiency and reduces heat loss, especially during cold nights, which helps lower operating costs.

How to maintain the heat pump for maximum efficiency?

To maintain optimal heat exchange efficiency, regularly clean the heat exchanger surface and air filter to prevent dust, leaves, or debris from blocking heat dissipation and air intake.

How to perform freeze protection in winter?

During cold seasons or when not in use for extended periods, drain all water from the unit to prevent freezing and damage to the heat pump pipes.
