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.
What is the purpose of P1 and P2 on the right side of the heat pump wiring?

They are used to connect the power cables of the water pump. Once connected, the heat pump can act as the power source for the pump, enabling simultaneous start/stop. This requires both the pump and heat pump to be on the same voltage.

Can the heat pump be used in saltwater pools?

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

Is my pool pump compatible with the heat pump?

There is minimum water flow rate required for each models.

  • 22,000BTU requires 660GPH
  • 35,000BTU requires 1188GPH
  • 55,000BTU requires 1717GPH
  • 75,000BTU requires 2377GPH
  • 100,000BTU requires 5547GPH
How should I wire my heat pump? Hardwiring?

The customer needs to connect L1, L2, and ground wire on the left side. Terminal screws must be tightened. Pictures have been provided.

  • HEX100: Voltage 220V, rated current 30A, max current 32A. Recommended circuit breaker: 40A or higher.
How do I choose the correct wire gauge for HEX022, HEX035, HEX055, HEX075, and HEX100?
  • HEX022: 0–25m use ≥12 AWG; 25–50m use ≥10 AWG; 50–100m use ≥8 AWG
  • HEX035: 0–25m use ≥12 AWG; 25–50m use ≥10 AWG; 50–100m use ≥8 AWG
  • HEX055: 0–25m use ≥12 AWG; 25–50m use ≥10 AWG; 50–100m use ≥8 AWG
  • HEX075: 0–25m use ≥10 AWG; 25–50m use ≥8 AWG; 50–100m use ≥6 AWG
  • HEX100: 0–25m use ≥8 AWG; 25–50m use ≥6 AWG; 50–100m use ≥4 AWG
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.

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.

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.
