Frequently asked questions about heat pumps

What is an air source heat pump?

These innovative pumps heat the water in your hot tub or swim spa using renewable energy. They're a fantastic alternative to traditional heating systems and deliver up to three times more warmth.

How does an air source heat pump work?

These pumps push a refrigerant through the copper heat exchanger coils. Then, the compressor and condenser work together to change the refrigerant's state from a cool liquid to a warm gas. In heating mode, the liquid refrigerant boils as it travels through the coils. Any heat carried within the refrigerant is stored until it evaporates; then, the gas is compressed,which increases its temperature. Finally, the gas moves through a pressure valve, which returns it to a liquid state while transferring the heat to the element.

How much energy will l save?

Our tests showed that for every 1kW used, you will receive 2kW of energy in an environment of 10c. This efficiency improves with increased temperatures, rising to 4kW in temperatures over 20c.

Are air source heat pumps expensive to run?

Air-source heat pumps are an excellent investment. With one, you can earn back your investment after 2 years of use and enjoy up to 50% annual savings.*

*These savings are based on an average hot tub and UK energy costs when powered on permanently. Your savings may differ based on overall usage, weather, temperature, cover, insulation, changes in energy costs, and your hot tub's age and efficiency.

**The colder the ambient temperature and below 15°C, the longer it will take to heat up to your ideal working temperature.

What insulation should I use for my hot tub?

Open tab

Every hot tub is built with space within the cabinet which can reduce the efficiency of a hot tub if it is not insulated properly by introducing cooler air and allowing heat to dissipate. Lots of hot tubs are built with insulation inside the hot tub, this prevents the heat escaping from the sides of the tub and makes your hot tub more efficient to run.
