As the costs of energy rises, you can help keep your hot tub or swim spa water heating costs to a minimum, saving up to 65% on traditional spa water-heating methods. Air heat source pumps are acknowledged for having outstanding COP ratings (the term COP is the official measurement of its “Coefficient of Performance”), some as high as 14:1 (the ratio of energy, or in the case of the AquaIntel air heat source pump, the heat emitted in relation to the energy used to produce it).

An air source heat pump is by far the most energy-efficient and economical way to heat your hot tub or swim spa. An air source heat pump efficiently extracts natural heat from the environment. The heat pump fan then draws the air in and over the evaporator coil which contains an advanced liquid refrigerant. The refrigerant turns into a gas which is then compressed to increase the heat and passes through the heat exchanger which transfers to water to heat it up. It’s very much the same principle as how a fridge works, only in reverse.

The whisper-quiet AquaIntel is suitable for both hot tubs and swim spas. It operates at temperatures from -5°C to 43°C, and its powerful, yet cost-effective 7kW heater features WiFi touch controls that can be operated remotely from anywhere with an internet connection to your home, via the InverGo App.

AquaIntel’s 7kW heater with its anthracite grey-coloured stainless steel shell, includes free delivery and installation and comes with a two-year warranty. This is an extremely high-regarded air source heat pump.
