Vian Power S7+ Heat Pump

The Vian Power S7+ hot tub and swim spa heat pump is an advanced heat pump that is a crossover model for hot tubs and swim spas. This Full DC Inverter heat pump is capable of operating down to -10°C ambient temperature.

An 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.

The electric heater in a hot tub or swim spa is known as a resistance heater and is very much like the element in a kettle. This resistance heater can only ever have a CoP of 1. This means for every 1 x kilowatt of power used by the electric heater then only 1 x kilowatt of heat is produced. If compared with a standard electric heater in a hot tub, then we can easily see that an air source heat pump is a far more efficient and costeffective 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, then 8 x 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.

The S7+ is a Full DC Inverter model that regulates 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.

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.
