Air-Source Heat Pumps

Significantly reduce
your running costs.

We supply and install four heat pump models — sized to suit your hot tub, your garden and your budget.

How it works

Heat from the air
around you.

A standard hot tub heater converts electricity straight into heat — which is expensive. An air-source heat pump works like a reverse fridge, extracting warmth from the surrounding air and transferring it to your water. For every unit of electricity used, a good heat pump typically produces four to six units of heat.

The result is noticeably lower running costs — particularly valuable if you use your hot tub through winter.
