How much will it cost to run my hot tub and how can I reduce it?

Updated: Nov 11, 2023

The cost of energy is relevant for everyone at the moment and should definitely be a consideration when purchasing your hot tub.

In truth, the exact size, make and model of the hot tub you plump for, as well as how much you use it will determine how much electricity is required to run it but between £80 and £100 per month is a good estimate.

Larger hot tubs with more jets and features generally require more energy to heat and then maintain the desired temperature.

But there are several simple ways to ensure your fantastic new spa is running as efficiently as possible.

For example, the environment where your hot tub is placed is a key factor. If you’re in a sheltered space which has protection from the wind, and any potential rainfall, then the water has a better chance of staying warm, and less energy is needed to maintain it.

The temperature you want your hot tub water to be is also directly linked to how much energy you will use to heat it. Most people opt for between 36°C and 40°C, but bringing it down by just a degree, or half a degree, can reduce the cost, without sacrificing your comfort.

The heating phase of a hot tub is when it consumes the most electricity as it is likely to take several hours to heat the water to your desired temperature.

Taking a step as simple as ensuring your hot tub is covered, whenever you aren’t in it, means the temperature will stay closer to your preferred setting, and will not require as much energy to bring it back up.

Once the hot tub reaches the desired temperature, it enters the maintenance heating phase. During this period, the heater operates intermittently to sustain the water temperature and is much more energy efficient compared to the heating phase.

Additional features such as lights, speakers and other gadgets and gizmos will need more electricity to run, but those in isolation should not have too heavy an impact on running costs.

The most efficient way of heating your hot tub is with an Air Source Heat Pump – which can also be purchased via Aqua Warehouse – although there is a larger upfront cost. Many hot tubs also offer advanced insulation to keep things nice and toasty.

Furthermore, some models include a heat lock system which naturally recycles heat generated by the pumps, make it more energy efficient.

Maintaining your hot tub regularly, with proper cleaning and servicing of the jets and filters will mean they continue to work efficiently and keep the tub running properly.
