When considering purchasing a hot tub, a common question people ask is about the cost of running it.

However, with the rising energy costs, there is now a great opportunity to invest in Hot Tubs Direct Air Source Heat Pumps.

These heat pumps are an efficient and cost-effective way to heat your hot tub or swim spa, providing savings on energy bills throughout the year. In fact, air source heat pumps have been proven to be beneficial for heating homes, commercial spaces, and swimming pools, and are becoming increasingly popular for hot tubs as well.

How does a heatpump work?

The operation of a heat pump involves utilising natural heat from the outdoor air to warm up water. This is achieved by the heat pump fan drawing in the air and directing it over an evaporator coil that contains a specialised liquid refrigerant. The air then transforms into a gas which is compressed to raise the temperature. This heated gas subsequently flows through a heat exchanger, transferring the heat to the water and thereby raising its temperature.

What are the benefits of an Airsource Heatpump?

Energy Efficiency: Air source heat pumps are highly energy-efficient as they can extract heat from the outdoor air even when temperatures are as low as -15°C. This means they can provide heat to your hot tub or home using less energy than traditional heating systems, resulting in lower energy bills.
  • Cost Savings: As air source heat pumps use less energy to heat your hot tub or home, they can lead to significant cost savings over time, especially as energy costs continue to rise.
  • Environmentally Friendly: Air source heat pumps are an eco-friendly heating option, as they use renewable energy from the air and do not produce any direct emissions.
  • Versatility: Air source heat pumps can be used for heating hot tubs, swimming pools, homes, and commercial buildings, making them a versatile heating option.
  • Low Maintenance: Air source heat pumps are generally low maintenance and have a long lifespan, with many manufacturers offering warranties of up to 10 years.
  • Year-round Use: Air source heat pumps can be used all year round, providing heat during the winter months and cooling during the summer months.
    • How much energy/money will I save?

    A controlled test was conducted to determine the energy savings provided by air source heat pumps.

    The test involved running the same hot tub for 72 hours with and without an air source heat pump, with a one-hour filter cycle, while maintaining a water temperature of 39 degrees Celsius and an average outside air temperature of 16 degrees Celsius.

    The test was conducted in accordance with the guidelines established by the California Energy Commission (CEC). Below are the results of 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 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?

    Utilising an Air Source Heat Pump to heat a hot tub can result in significant cost savings, as demonstrated by the figures below that depict the cost per day following our 72-hour test. Hot Tub with Air Source Heat Pump – £0.79 a day

  • Hot Tub with no Air Source Heat Pump – £1.63 a day
    • How do I order an Air Source Heatpump?
