How Much Does It Cost to Run a Hot Tub?

August 17, 2022 / Elicia Allott

The most common question when people are thinking about buying a hot tub is how much does it cost to run a hot tub?

With energy bills increasing there has never been a better time to invest in the new Superior Wellness Air Source Heat Pumps; the efficient way of heating your hot tub. They can be used all year round giving great savings on energy bills.

Air source heat pumps are an energy-efficient and economical way of heating your hot tub or swim spa. They have already proved to be beneficial for heating homes, commercial spaces or swimming pools and now they have become increasingly popular for hot tubs.

How does a heat pump work?

Heat pumps heat up the water by extracting natural heat from the outside air. The heat pump fan draws in the air and directs it over the evaporator coil which contains an advanced liquid refrigerant. The air turns into a gas which is then compressed to increase the heat. This hot gas passes through the heat exchanger which transfers the heat from the hot gas to water and heats it up.

What are the benefits of an Air Source Heat Pump?

  • Savings on hot tub heating bills and energy usage
  • Works all year round and down to -15 degrees external temperature
  • Self-regulating and timer controlled

How much energy will I save?

We have undertaken a controlled test in the showroom here at Miami Spas. We tested the same hot tub without using an air source heat pump and then with an air source heat pump.

This was for a 72 hour test period, with a one-hour filter cycle.  The water temperature was 39 degrees centigrade and the average outside air temperature was 16 degrees centigrade.

The test was in accordance with the CEC guidelines (California Energy Commission).

The results below are for the 72 hour test period.

How much energy will a hot tub use per day?

The test results per day from the 72 hour test for the energy usage were as follows:

 
Hot Tub with Superior Wellness Air Source Heat Pump – 3.36 kWh
Hot Tub with no Air Source Heat Pump – 6.96 kWh

How much will it cost to run a hot tub per day?

If you are using an Air Source Heat Pump to heat a hot tub it will generate a considerable saving. The figures below show the cost per day following the 72 hour test we conducted.

 
Hot Tub with Superior Wellness Air Source Heat Pump – £0.79 a day
Hot Tub with no Air Source Heat Pump – £1.63 a day

From the results we can say that by using an Air Source Heat Pump you can save approximately 50% on energy bills and energy usage.  The costs will vary depending on the hot tub, your energy tariff, how much you use your hot tub and your filter cycle.
