What is a heat pump and why use one?

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 70% 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 or swim spa.

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

Why use a heat pump?


Energi Heat Pumps are one of the most energy efficient and cost effective ways to heat any hot tub or swim spa. All Energi Heat Pumps are powered by a Mitsubishi DC Inverter which are incredibly silent (only 20~29 Db(A) at 10m away) but most importantly they are very energy efficient.

Save between 60-70% on your hot tub or swim spa running costs!
