Air Source Heat Pumps

Get an Air Source Heat Pump for Your Hot Tub or Swim Spa

Explore our fantastic range of air source heat pumps, specifically designed to reduce energy usage and keep your electricity bill low when using your hot tub. An air source heat pump can reduce your hot tub energy bills by up to 70%. These pumps draw power directly from your hot tub (or swim spa) without needing any additional electrical installation. Your hot tub will require a slight modification to integrate the heat pump system for water heating.

How Do Hot Tub Air Source Heat Pumps Work?

An air source heat pump extracts heat from the outside air through a series of tubes containing eco-friendly R32 refrigerant. As the outside air flows over the tubes, it warms the refrigerant, converting it from liquid to gas.

This gas is then pushed through a compressor, increasing its pressure and significantly raising its temperature. The heated gas passes through a titanium heat exchanger.

Your hot tub’s water circulation system is connected to the air source heat pump. As the heat from the gas travels through the heat exchanger, it heats the water in the pipes.

The refrigerant cools down, reverts to liquid form, and the process repeats.

Will an Air Source Heat Pump Work on My Hot Tub in Winter?

Absolutely! Due to the way hot tub air source heat pumps operate, they continue to generate heat for your hot tub’s water system even when ambient temperatures drop below zero degrees. This is because the compression of the refrigerant produces heat. Be aware that some cheaper air source heat pumps do not function below zero and may be ineffective in colder winter months. All of our models are designed to work efficiently at temperatures well below zero degrees.

This method is not only cost-effective in the long term but also more environmentally friendly.
