Order a new hot tub with an air source heat pump for up to 70% lower running costs, or have a heat pump fitted to your existing hot tub.
How does an air source heat pump work with a hot tub?
An air source heat pump is a device that uses electricity to transfer heat from the air to a pool or hot tub, using a refrigerant as a medium. The heat pump consists of an outdoor unit and an indoor unit, both of which contain a refrigerant.
To heat the water in a hot tub, the heat pump works like this:
- The outdoor unit draws in air and passes it over a set of coils containing the refrigerant.
- As the air passes over the coils, it heats up the refrigerant, which absorbs the heat from the air.
- The heated refrigerant is then pumped to the indoor unit, where it passes through a set of coils containing the water for the hot tub.
- As the refrigerant passes through the coils, it transfers its heat to the water, heating it up.
- The refrigerant then returns to the outdoor unit, where the process starts again.
Air source heat pumps are a more energy-efficient way to heat a hot tub or pool, as they use the heat from the air to heat the water, rather than generating heat directly. They can be a more environmentally friendly and cost-effective alternative to traditional gas or electric heaters.
