How does an inverter pool heat pump work?

Are you after a cost-effective pool heating option that efficiently heats your pool water, no matter the weather? Then an inverter swimming pool heat pump may be the solution you are looking for.

Driven by electricity, a pool heat pump generates natural heat from the outside air to warm the water. The next generation of inverter pool heat pumps intelligently adjust the operating capacity to improve the efficiency of air-water heating exchange and bring more extra benefits.

Benefits of using an Inverter Pool Heat Pump.

Unlike traditional pool heaters, an inverter pool heat pump only needs a small amount of electricity to power the compressor and the fan that pulls in the warm air and transfers the heat directly to pool water.

Energy Efficiency
Since most of the heat is sourced from natural air, an inverter pool heat pump like the Premier Series can offer an impressive COP of up to 15.0. By consuming every unit of energy, it can produce 15 units of heat in return. For reference, neither gas nor electric pool heaters have a COP above 1.0.

With such outstanding energy efficiency, the electricity cost of inverter swimming pool pumps is incredibly low, which reflects not only on your bills but also on the environmental impact in the long run.

With advantages in low energy consumption and high efficiency in heating exchange, inverter pool heat pumps are highly eco-friendly in protecting the environment.

Silence and Durability
As most noise comes from the operating compressor and fan, an Inverter pool heat pump like the Premier Series can reduce noise to as low as 42dB(A) due to its unique InverPad Technology. Moreover, without running at full speed continuously, inverter pool heat pumps are more durable with a longer warranty than traditional on/off pool heat pumps.

With all the benefits mentioned above, how does an inverter pool heat pump exactly work to realise the air-water heating exchange?

How does an Inverter Pool Heat Pump work?


  1. The inverter pool heat pump pulls in cool water from the pool water pump
  2. The water circulates through the Titanium Heat Exchanger
  3. The sensor on the Titanium Heat Exchanger tests the water temperature
  4. The inverter controller automatically adjusts the operation capacity
  5. The fan in the pool heat pump draws in the outside air and directs it over the evaporator
  6. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas
  7. The warm gas refrigerant passes through the compressor and is heated to a high temperature
  8. The hot gas passes through the coil’s condenser (Titanium Heat Exchanger). It then transfers the heat to the cooler water
  9. The heated water then returns to the pool
  10. The hot gas refrigerant cools and reverts to liquid form and back to the evaporator
  11. The whole process starts over again and continues till the water gets heated to the goal temperature

Aside from the electricity used to power the unit, an inverter pool heat pump uses very little energy, making it one of the most energy-efficient and cost-effective options for heating your pool.

Moreover, its value in protecting the environment is hard to be ignored. It’s absolutely a win-win choice for you and mother nature.
