Hot Tub revive, Swim Spa air source heat pump

The fan in the air source heat pump draws air over a network of tubes that look a little like a car radiator. These tubes are filled with an eco-friendly refrigerant. The air then passes over the tubes warming up the refrigerant and turning it from a liquid into a gas. This gas is passed through a compressor which increases the pressure and significantly raises the temperature of the gas, which is then passed through a titanium heat exchanger. The swim spa or hot tub’s water circulation system is plumbed through the air source heat pump and the heat from the gas travels through the heat exchanger, which in turn heats the water from the hot tub or swim spa as it passes over it.


The refrigerant then cools and turns back into a liquid and starts the process all over again. Due to how the system works, our air source heat pumps will still produce heat even if the ambient air temperature is below zero as the compression process of the refrigerant gas creates a lot of heat. Not only is this a far more cost-effective solution to heat your hot tub or swim spa, but it is also a much more eco-friendly option.


ON/OFF heat pumps. When ‘on’, these models will draw a constant amount of power to operate, they can be considered to always be at maximum power when working.


Inverter heat pumps have the benefit of being able to have their power consumption varied and in some cases, this is done smartly by the machine itself based on the ambient temperature and heating demand. Sometimes referred to as stepped inverter, these models may have stages or steps of power use. Step 1 for example would be a very low power mode, step 3 a medium power use and step 5 would be full power. They also have the added benefit of being quieter than an ON/OFF heat pump.


Full inverter heat pumps can regulate the power consumption over a much more fluid range so rather than steps or stages of power draw like a stepped inverter machine, they can vary the power they consume across their whole range. This technology makes full DC inverter heat pumps the most efficient types of machine over the long term. Full DC Inverter models are also very quiet.
