How much does it cost to run a hot tub?

Most potential buyers will want to know how much hot tubs generally cost to run on average before they quite literally dive in and splash out on a purchase.

Hot tub running costs are largely dependent on factors such as the environment, the quality of the hot tub, the frequency of use, insulation quality and hot tub hygiene.

We’ve compiled together a guide to hot tub running costs, allowing you to make the best, most informed decision about investing in your own spa haven.

How much energy does a hot tub use?

Hot tubs will run via an electrical supply with the exception of wood-fired hot tubs. Generally, hot tubs will require between 13 and 40 AMPS of power in order to run efficiently.

The primary source of energy consumption is the hot tub heater which typically has a 120 or 240 voltage. The water pump will also consume energy.

How much energy your hot tub consumes will depend on how frequently you use your hot tub. As hot tubs are generally left to run 24/7, this will always bump up your overall energy bill.

What can bump up running costs?

The running hot tub cost may be higher depending on certain factors:

  • The hot tub size (the bigger the tub, the more heat required)
  • The temperature setting of the hot tub
  • Outdoor temperature
  • The hot tub manufacturer
  • The quality and age of the water heater

How much on average does it cost to run a hot tub?

We cannot give a specific answer as to how much your hot tub running costs will be without knowing the size of the tub, the manufacturer and energy supplier. However, we can give you a rough idea based on the average hot tub user.

Hot tub running costs generally add up to approximately £4-5 per week for those who meeting the following criteria:

  • You have an average energy tariff of 13p per kWh
  • You use the hot tub 4 times a week for 30 minutes at a time
  • Your hot tub is a relatively new model

How can I keep hot tub running costs down?

There are a number of ways to keep hot tub running costs down. It is always a good idea to invest in the right hot tub chemicals and hot tub accessories as these can help not only maintain your hot tub and prolong its life, but also keep unnecessary costs down.

Insulation

If your hot tub is well insulated, then this can help to save on running costs. Research has found that roughly 60% of heat escapes through the hot tub surface. Having poor quality insulation will reduce the energy efficiency of your tub.

There are a number of different methods to insulating your hot tub:

Full foam insulation

A full foam insulation is a typical method of insulating hot tubs. In this method, hot tubs are fitted with foam to smother the hot tub plumbing. This can make the manufacturing process more expensive, making the hot tub fall on the pricier side.

However, this is likely to keep running costs down as the pipework is protected and heat is retained far better, meaning you get more value for your money.

Spray on insulating foam

Insulating foam can be sprayed over the hot tub shell to help enhance insulating properties, although this is not quite as efficient as a full foam insulation method.

Covers

Investing in a quality hot tub cover will keep running costs down by trapping heat in your tub, saving you time and money in not having to constantly keep reheating it.

Reduce temperature

Having your hot tub temperature too high can bump up energy costs. We understand that part of the hot tub experience is to relax in hot bubbles, but without going to the extreme of sitting in lukewarm water, turning down the temperature a few notches might knock a few pounds off that next bill.

Clean your filter

Hot tub filters can get easily clogged up and dirty over time. Their job is to keep dirt, debris and other contaminants out of your tub water and so it’s inevitable that they end up bearing the brunt of it all.

If you do not clean out your filter regularly, then contaminants will remain stuck in the filter and this can affect the water flow and cleanliness of the tub water. If your filter is clogged up, then the hot tub filtration system has to work harder to do its job and if it has to work harder and longer, this will consume more energy.

As part of general hot tub maintenance, you should rinse out your filter every week using an instant filter cleaner or overnight filter cleaner.

Shock your tub regularly

You should shock your hot tub on a regular basis to keep your hot tub water safe and clean for soaking. Shocking your hot tub refers to ‘shocking’ the water after it has been contaminated.

Shocking involves pouring shock compounds into the tub water that will kill bacteria and allow for cleaner, clearer and softer water.

You can shock your tub using hot tub sanitiser.
