A Vian Power Air Source Heat Pump can be up to 75% more energy efficient than standard heating options. Simply put, they produce more heat (energy) than they use in electricity (energy).

This relationship between the power used by the heat pump and the heat it generates is referred to as Coefficient of Performance (CoP). For example, if a heat pump has a CoP of 8, then it will produce 8 x units of heat for every one unit of electricity consumed.

If compared with a standard electric heater in a hot tub, then an air source heat pump is a far more efficient and cost-effective way of heating your hot tub or swim spa. This is because using the example CoP of 8 then for every 1 kilowatt of power consumed by the heat pump, 8x kilowatts of heat are produced.

The CoP of an air source heat pump will vary depending on the ambient temperature and the mode function set on the air source heat pump.

Technology

FULL DC INVERTER models 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 machines over the long term. Full DC Inverter models are also very quiet. By using far less energy than traditional heating methods, an air source heat pump is not only good for the environment but will save hot tub and swim spa owners a considerable amount of money. It is no wonder why hundreds of owners are opting to have an air source heat pump fitted to their hot tub or swim spa.

HOW DOES AN AIR SOURCE HEAT PUMP WORK?

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 R32 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.
