The use of a heating system for a swimming pool within the UK environment has, over the years, proved to be a difficult task. The use of traditional heating systems, such as gas boilers and electric heaters, is no longer economical and environmentally sustainable. The Air Source Heat Pump for Swimming Pool, however, has become the chosen alternative within the UK. In this detailed guide, we will examine everything you need to know about air source heat pumps for swimming pools, including their functionality, benefits, efficiency, costs, UK-specific factors, and a comparison between various models that have varying price tags.
What Is an Air Source Heat Pump for Swimming Pool?
An air source heat pump for swimming pool is an efficient way to heat a swimming pool using the heat energy from outside air. Unlike other sources for generating heat, it uses a refrigeration process to transfer heat energy from outside air to the swimming pool. Hence, it is far more energy-efficient than other heat sources. Even in a relatively cool climate such as the UK, the current range of air source heat pumps designed for use with swimming pools can handle temperatures as low as -5°C, so they can be used all year round, even from early spring through to autumn.

How Does an Air Source Pool Heat Pump Work?
The functioning of a pool heat pump relies on complex principles of thermodynamics:
- The ambient air is sucked into the unit by a fan.
- The air is then forced to pass over an evaporator that holds refrigerant.
- Absorbs heat from the refrigerated space to become a gas.
- The compressor raises the temperature of the gas.
- Heat is transferred to the pool water via a condenser.
- The refrigerant cools, becomes a liquid, and then starts over again.
This enables air source heat pumps designed for swimming pools to provide 5 to 7 times more heat than the electrical power consumed.

Why Air Source Heat Pumps for Swimming Pools Are Ideal for the UK
The most important reasons of Air Source Heat Pump for Swimming Pool include:
- Energy Efficiency and Low Running Costs: The cost of electricity in the UK is among the most expensive in Europe. Due to higher COP (Coefficient of Performance) ratings, an elite class pool heat pump can lower costs by up to 70% as compared to other electric methods of space heating.
- Environmentally Friendly Heating: The use of renewable heat from air greatly reduces CO₂ emissions. This harmonizes air-source swimming pool heat pumps perfectly with sustainability aims in the UK, as well as energy requirements for the future.
- Extended Swimming Season: A correctly sized inverter pool heat pump allows swimmers in the UK to enjoy a water temperature of between 26-30°C for an extensive period of the year.
- Quiet Operation: Modern full inverter heat pumps are designed for use in residential areas, running extremely quietly, which is a very important consideration for gardens and residential areas in the UK.
Key Types of Swimming Pool Heat Pumps
The most frequent cases are as follows:
- Inverter Pool Heat Pump: Using an inverter heat pump for a swimming pool, the compressor’s speed varies in accordance with the heat requirements, leading to the following:
- Higher efficiency
- Use less electricity
- Quieter operation
- Longevity
- On/Off Heat Pump: They cost less initially but use more electricity. They are less efficient later on.
- Air Source Heat Pump for Above-Ground Pools: Small to compact units intended for small volumes of water.

Choosing the Right Air Source Heat Pump for Swimming Pool
For this, it is better to consider the following:
- Pool Size and Water Volume: Choosing the right size of the pool is imperative because it makes all the difference in:
- Small pools (up to 20 m³): 5-7 kW
- Medium pools (20-40 m³): 8-12 kW
- Large pools (40-70 m³): 12-18 kW
- Commercial pools: 18 kW+
- 2) UK Climate Considerations: For UK conditions, always choose:
- Full inverter technology
- Operation down to at least -5°C
- Anti-freeze protection
- 3) COP and Seasonal Efficiency: Check that the COP is at least 4.5 (higher would be even better, and a good sign at lower temperatures prevailing in the UK).
