What is a heat pump?
A heat pump extracts heat from the air outside and brings it into the hot tub or swim spa using electricity. This means you get a bigger quantity of heat with less electrical power usage.

Energi Air-source Heat Pumps give you comfortable, consistent hot water.


More energy: Energi Heat Pumps are up to 75% more energy efficient than standard heating options.

Less carbon: The low-carbon technology in the heat pump helps reduce the carbon footprint of the hot tub.

Long Lifespan: Every Energi Heat Pump is IPX4 rated. Meaning they will be able to withstand the UK weather, come rain or shine.


Energi’s 5kW air source heat pump is packed with clever features. Its inverter technology means it can adjust its heating capacity between 20% and 100% depending on the heating demand. In addition, this model is equipped with a titanium heat exchanger, r32 eco-friendly refrigerant and is extremely quiet.
