Will a hot tub increase your energy bills per month?

hot tub energy costsYes!

Hot tubs run on an electrical supply. They usually need between 13 and 40 AMPS of power to run. The electricity powers the heater, pumps, lights and all the other working components on the hot tub. 

It’s usually recommended that hot tubs run 24/7. So it goes without saying that installing a hot tub will increase your monthly energy bills.

So, you need to consider the hot tub running costs before you buy.

How much does a hot tub cost to run per month?

Hot tub running costs vary massively between manufacturer. 

A well insulated and quality hot tub should cost you no more than £30-£40 a month. Potentially less, depending on the temperature you hold it at the level of insulation you have in the hot tub.

However, poorly constructed hot tubs can cost upwards of £100/month. So how do you know where the hot tub you falls on this scale?

Do cheap hot tubs cost more on electricity per month?

Quite often we are asked why our hot tubs are more expensive than some of the cheap hot tubs on the marketplace. There are a few reasons for that

But one of them is the life-long running costs of premium hot tubs in comparison to cheap hot tubs. It’s not that cheap hot tub automatically cost more to run than expensive hot tubs. But usually the quality of the build and insulation is lower, which makes the overall running costs more expensive. 

While the average running costs of a hot tub should be £30-£40 per month for a well build hot tub. It’s common for people to come to us with advice on how to lower their hot tub costs as they’ve bought elsewhere and it’s costing them £100-£120/month. Way higher than they budgeted for. 

We usually find these are either really cheap hot tubs. Or old hot tubs bought second hand.

Let’s look at the life-time running costs of a hot tub. Comparing a budget hot tub costing £4500. With a hot tub that costs £8000.

Hot tub 1: costs £4500 to buy + £100 per month to run.

Hot tub 2: costs £8000 to buy + £35 per month to run

Year £4500 hot tub (£1200/year) £8000 hot tub (£420/year)
Year 1 £5700 £8420
Year 2 £6900 £8840
Year 3 £8100 £9260
Year 4 £9300 £9680
Year 5 £10,500 £10,100

By half way through year 5, the cheap hot tub has cost you more in running costs alone. 

Quality hot tubs can routinely last 10 years plus. By year 10, if your cheap hot tub lasts that long, the cheap hot tub could have cost £4300 more than a quality hot tub.

And that is not to mention any money you have spent on warranty and quality issues in that time.

How to keep your hot tub running costs low

What can you do to ensure that when you buy a hot tub the energy bills are as low as possible? 

These are just a couple of things you should look out for when buying a hot tub to keep your running costs low.

  1. Buy a good quality hot tub
  2. Get the best possible electricity tariff. The lowest unit price will help keep your hot tub energy costs down.
  3. Keep your hot tub at temperature all the time. Little and often is the most efficient way to heat your hot tub. Plus it means it is ready to jump in 24/7. It’s not cost-effective to constantly reduce and increase the heat.
  4. A well-insulated cover. Sixty percent of the heat is lost through the top of the hot tub. A well-insulated cover helps keeps the heat in. 
  5. Insulate the cabinet. We recommend full foam insulation from the shell to the interior cabinet. This preserves heat. Plus it has the added bonus of securing the pipework to prevent the likelihood of leaks. 
  6. Turn of your air valves. If you have air valves or jets turn these to the off position when you are not using your hot tub. Introduction of air will lower the water temperature. Leaving these on when the filtration cycle runs will increase hot tub energy usage.
