Do hot tubs use electricity?  

Yes, hot tubs use electricity, and it plays an essential role in the operating and maintaining of a hot tub.  

Hot tubs typically need electricity to power the heating systems, jets, lights, and control panels.  

The heating element in a hot tub uses electricity to warm up the water to a desired temperature, and the jets and lights require electricity to function. The control panel of a hot tub, which allows you as a user to adjust settings and features, is powered by electricity.  

How to work out the cost to power a hot tub?  

Energy prices are changing all the time so noting down in this moment how much hot tubs cost to run in monetary terms isn’t easy.  

Don’t worry, if you’re wanting to find an exact figure at the time you read this article, you can work it out by factoring in what you are:

-Currently paying per kilowatt of electricity  

-Daily hot tub energy consumption

How is electricity usage for Jacuzzi® Hot Tubs measured?  

Electricity usage for Jacuzzi® Hot Tubs is measured by SmartTub®.

This means that the data is gathered from our hot tub users around the world who use their hot tub as they desire – This includes draining, re-filling and even when someone gets in for a soak on a snow day! 

What is SmartTub®?  

SmartTub® is a smart system that’s exclusive to Jacuzzi® Hot Tubs.

It allows you to remotely control and monitor your hot tub from anywhere with a cellular connection and is a key tool used to measure the average kilowatt usage.

Do hot tub electricity costs change between summer and winter?  

Using a hot tub is similar to using your central heating system. You will use more energy when it gets colder and less in the summer.  

Note - The 6 kWh average taken from Jacuzzi® SmartTub® users is the result of global daily energy monitoring across the year, so takes this into account.  

How much electricity does a hot tub use in winter?  

The average kilowatt usage per day for your hot tub may be higher for you in the winter, depending on where you are.  

That’s because the air temperature surrounding the hot tub is lower in the winter and the hot tub will need to use more energy to maintain your desired water temperature.

You may also set your hot tub a few degrees warmer in the winter.  

How much electricity does a hot tub use in summer?  

The average kilowatt usage per day for your hot tub may be lower for you in the summer, this also depending on where you’re located.  

If the air temperature surrounding your hot tub us warmer, the hot tub won’t need to use as much energy to maintain the water temperature you have set. It’s likely that you’ll turn your hot tub down a few degrees in the summer months too.

What hot tub energy costs are variable?  

You may be asking yourself, okay, what factors may influence if my hot tub daily average energy usage is above or below the latest data of 6 kWh per day? Some of the points to keep in mind include -  


The warmer the climate, the less electricity you will use to heat your water to your desired temperature. The cooler the climate, the more you will need to use the heater to maintain the water temperature.  

Hot tub placement  

A hot tub in a sheltered location e.g., with a shade cover above or in a corner will be less vulnerable to weather changes (e.g., cold wind, hail, snow). This can help minimise heat loss as less energy is needed to maintain the hot tub’s water temperature.

The warmer you heat the water, the more energy you will draw from the heater.  

Drain and refill hot tub   

Emptying your hot tub, then refilling and heating the water comes at a cost of both water resource and electricity. However, the median average of 6kWh per day covers everything including when our Jacuzzi® Hot Tub customers drain and refill their hot tubs.  

Expert tip – If you were to carry out this task on a warmer day or can use warmer water to fill your hot tub, this should help you reduce your energy usage.   

Hot tub usage  

The more time you spend using the jets and lighting, the greater the energy usage.  

Time of day   

The national average price per kilowatt of electricity will vary during the year, based on demand.

What features of a Jacuzzi® Hot Tub help keep energy costs down in the UK?

Hot tub insulation  

Jacuzzi® Hot Tubs in the UK are fitted with varying insulation, depending on the collections. On the J-200™ you’ll find EcoShield insulation which is made with polystyrene slabbing and a foil backing and an Astrofoil space blanket.  

All hot tubs in the J-200™ range are more efficient than the standards set by the California Energy Commission.  

The J-300™ and J-400™ collections are equipped with full foam insulation and an insulating SmartSeal® foil blanket. (This excludes the J-335™ which has a different form of insulation as it is made in a different factory).  

ProStream™ circulation pump  

There are several jet types that Jacuzzi® Hot Tubs use, depending on which model you’re looking at. One that provides a number of energy efficiency benefits is the ProStream™ circulation pump.  

It’s designed to maximise the flow of water while using a low amount of energy. It can also be activated to run on energy efficiency mode, the same functionality you can also set the filtration too, so it will continue to clean the water, without relying on the jets to be running.  

Pump to jet ratio  

It may not be something you’ve thought about but powering too many jets at once, when you don’t need to, can lead to energy wastage. The pumps are designed to power the right number of jets in order to conserve energy.  

ProLast™ Cover  

One of the key places for hot tub heat loss is through the top of the hot tub when the cover is off. ProLast™ covers are exclusive to Jacuzzi® Hot Tubs and have a heat seal on the underside to prevent heat loss in different weather extremes.

They are also filled with dense insulating home which makes them more effecting at trapping heat in the water. The extra bit of weight in the cover also makes it easier for it to withstand a downpour or rain or snow.  

Jacuzzi® SmartTub®  

There are several features on the SmartTub® that you can activate from your hot tub, which will help you both save and keep track of energy usage.  

Smart Heat ModeIf you only plan to use your hot tub a few times a week, you can schedule the time and day you want use it and it will provide you with an estimate of how much energy you may save. You can use it as you would a programable timer for a heater in your home.  

Vacation Mode If you are going away and spending a period of time away from home, rather than turn your hot tub off, switching on vacation mode means the water will cool to a point that it can still effectively run necessary filtration cycles. You will be able to save up to 30% on standby heating costs.  

Energy usage reportsAllows you to see your energy usage in kWh for 7 days, 14 days or monthly.

Up to 6-stage filtration system  

Depending on the hot tub model, Jacuzzi Hot Tubs are equipped with up to 6 stages of water filtration. These steps include capturing large debris, small debris, clarifying the water and purifying it through the use of ozone gas and a UV-C bulb (CLEARRAY Active Oxygen™) which reduces hot tub chemical usage by up to 50%.

How does this help save on energy? Cleaner, clearer water can be utilised in the hot tub for longer so you can reduce the frequency of draining, refilling and heating the hot tub water.
