Hot tub energy efficiency

The rise in inflation is affecting all aspects of our lives. With that in mind, many of us are trying our best to cut down where we can and save a little more money. In this blog, we’re going to help you with the most energy-efficient hot tubs.

We know that hot tubs and swim spas are a luxury item to own. They’re an investment rather than a one-off treat. With energy bills changing, many people are more wary of their energy usage. We’re sure that you’re already on the lookout for ways to reduce your hot tub running costs, and we’ve got all the tips you need.

The good news is that there are plenty of solutions, so you don’t need to worry about not being able to use your spa as often.

What’s the most energy-efficient hot tub brand?

If you’re looking for energy-efficient hot tub brands, we truly believe that you can’t go wrong with Master Spas™. Every model of hot tub and swim spa they manufacture meets and exceeds strict regulations set out by the Californian Energy Commission (CEC).

Master Spas™

Master Spas™ is one of the biggest hot tub and swim spa manufacturers. They’ve been building luxury spas since 1996.

Master Spas™ manufactures some of the world’s most efficient hot tubs and swim spas – largely due to the combination of quality materials and modern manufacturing processes – coupled with rigorous thermal testing at production level.

Master Spas™ utilise highly efficient Icynene foam insulation that offers the highest insulation values – whilst retaining the ability to be easily removed and replaced for future service issues. Quality control throughout the whole production process ensures that the ‘fit and finish’ of all spas optimises their efficiency and maximises heat retention.

The Icynene foam insulation works as a barrier between you and the cold outdoors, allowing you to stay comfortable, reduce heat loss and save money. Master Spas™ can also offer you an energy-efficient swim spa.

All new Master Spas™ hot tubs and swim spas are thermally tested in their in-house thermal chamber, where the spa’s energy consumption is monitored over 72 hours. During this time, key variables such as water and temperature-controlled tests are completed. The results of this testing are independently verified and published.

Additionally, this data is submitted to the Californian Energy Commission (CEC) – the only test worldwide for portable hot tubs and swim spas. All Master Spas™ exceed the standards of the CEC; customers can be confident that their investment offers high efficiency and low operating costs.

Strong Spas

Strong Spas is another energy-efficient hot tub brand. The spa cabinet retains heat well due to having a dual-walled design, leading to lower running costs and better energy efficiency. Strong Spas also come with high-quality covers for maximum heat retention when you aren’t using your hot tub.

Hot tub cover

All of our luxury hot tubs and spas come with a perfectly fitting, quality cover, so you can keep operating costs low.

But, as with everything, over time, the thermal cover can become worn out, especially when it’s fighting off the weather in the UK! With this in mind, it is important that you check your hot tub cover every now and again to ensure that there are no cuts or rips in the material.

Regularly checking that your hot tub cover is intact can help prevent heat from escaping from inside your hot tub, meaning that it’ll be warmer when you decide it’s time to relax. All of this can help to promote energy saving and lower operating costs.

Set your water temperature

If you’re looking to lower your energy consumption, you could consider setting your hot tub to a steady temperature and leaving it at that all the time. This can reduce operating costs as you won’t have to use a lot of electricity heating it up every time you want to hop in.

It also means you won’t have to wait at all for your hot tub to heat; you can just grab your favourite drink and head in.

Keep on top of your cleaning and filters

We say this a lot, but caring for your hot tub and maintaining cleanliness is so important. If you can clean your hot tub little and often, while completing a full clean a few times a year, you’ll save yourself money on chemicals and water bills.

If you leave your hot tub to become grubby and let the spa water go green, you’ll have to empty it and re-fill it while ensuring the chemicals are in balance and testing is being completed.

Many people overlook how important your hot tub filter is. If your filter becomes dirty, your hot tub will have to work much harder, and you may cause damage. Before inspecting your hot tub filter, you should turn off your hot tub. You can then remove the filter and give it a good rinse. After drying completely, the filter can be returned.

You should rinse your hot tub filter at least once a week to ensure that it is kept in good working order. Once a month, you should remove the filter and leave it to soak inside a specific filter cleaning solution overnight to remove any bacteria.

Using a hot tub in winter vs summer

Imagine sitting, bubbling away on your comfortable lounger, as the cold, crisp outside air reaches your face…ahhh and relax, even when it’s cold outside! We know how much everyone loves a hot tub in winter.

We also know how tempting it can be to set the water temperature to 40 degrees. But, there’s really not much between having your hot tub a few degrees lower, so you might find that you enjoy the warm water slightly more than it being hot. This could save you a bit of money, as your hot tub doesn’t need to work as hard to heat up.

In the summer months, you may find that you don’t want the water quite as hot, as you’ve already got warm air outside. This means your hot tub water will naturally be warmer and require less heating, which means hopefully a lower energy bill!

Plan ahead

This one is particularly useful to those who are still researching hot tubs before they buy! It goes without saying that any building can help to reduce the wind, so why not position your hot tub by a building to reduce the chill? If you’re able to do it, you might as well save money in the long run.

You’d be surprised how much of a difference it can make, and it usually also means you’ll have a shorter walk when you need a new drink!

Hot tub energy costs

Unfortunately, it’s impossible to give a 100% accurate prediction for a hot tub energy bill. How much it will cost to run your hot tub will depend on a number of factors, including:

  • How often you use your hot tub
  • How long you use your hot tub for
  • Your set water temperature
  • Your use of jets
  • The cost of your electricity tariff
  • The wind speed

However, we’ve done our best to find an estimate for each hot tub, which you can find on each product page.

Our hot tub running costs are estimated based on a number of average conditions, including energy prices, water temperature, jet usage, ambient temperature and cover usage. Each test has been conducted to meet industry requirements so you can have some peace of mind.
