A hot tub heat pump installation (also called an air-source heat pump, ASHP) uses ambient air to deliver up to 4–5× the heat per kWh vs a standard electric element — dramatically cutting running costs.
A hot tub heat pump installation doesn’t “make” heat — it moves it from the outside air into your water. Also called an air-source heat pump (ASHP), a quality unit can deliver 4–5× more heat per kWh than a standard electric element — so you pay far less to enjoy your spa.
Ambient air passes over a refrigerant coil and releases heat into the system — even in cool UK weather.
The compressor raises the refrigerant temperature, transferring heat efficiently into your spa water.
Your spa pump circulates water through a titanium heat-exchanger for efficient, corrosion-resistant heating.
Actual savings depend on ambient temperature, target water temp, usage hours, and model sizing.
Cold-climate models include defrost control and maintain output in low temperatures. We’ll size and specify the unit for your usage to keep performance reliable year-round.
