Heat Pump Help & Advice

Choosing a heat pump for your hot tub or swim spa

The right heat pump depends on water volume, target temperature, ambient conditions, how often the spa is used and how quickly you want it to recover heat.

5kW or 7kW?

Compact spa heat pumps are often a good match for hot tubs where space and electrical demand matter. A higher-output model can provide stronger recovery performance for larger tubs or colder conditions.

9kW or 11kW?

Larger inverter heat pumps can be better suited to swim spas and larger water volumes. Correct sizing is important: more output is not automatically better if the flow rate and installation are unsuitable.

Can a heat pump replace the spa heater?

Installation arrangements vary by hot tub and swim spa. In many installations the heat pump is added to the circulation system to reduce reliance on the standard electric heater. We can advise on the correct arrangement for your spa.
