Hot tub energy usage vs common goods

Everyone loves a little something to treat themselves with. Picking up the odd ‘coffee shop’ coffee, a trip to the cinema or a Saturday lunchtime burger. The few pounds we spend here and there seem so small but give us such a big smile.  

So, can you spend just a few pounds to get excellent hydromassage? On average, yes you can! And as you can see below, that tiny spend is not only equivalent to the other ‘everyday treats’ you enjoy, in many cases it can actually cost less.

What affects hot tub energy costs? 

There are a number of factors that influence the energy costs of a hot tub. Good news, there are some simple measures you can take to reduce energy usage!

How long you use your hot tub  

Think less is best. When you slip into your hot tub for your hydromassage, you are looking to relax, ease your muscles, relieve aches and pains and generally feel better about yourself. For the jets to help with all this, you only need them to work on your body for 20-30 minutes

By staying in longer you can sometimes begin to feel a little lightheaded and nauseous because of the heat. And nobody wants to spoil their experience. 

So don’t say ‘I’ll just have 10 more minutes’. Your body won't really thank you and neither will your electricity bill. The nearly 90 hours a year you cut - based on a daily hydromassage - can reduce hot tub energy usage.

Hot tub size and jet functions  

A general factor to consider when it comes to energy usage is the size of the unit. The more water the hot tub holds, the longer it takes the heater to warm up, and the more you pay.

You then need to consider the pump and the number of jets. Again, more jets can cause the pump to work harder, and will require more energy to function.

Water temperature 

Like cranking up your central heating when you’re cold, increasing the temperature of the water will likely trigger an increase in power use.

However, if your hot tub is equipped with an energy saving heat programme, such as SmartTub®, then you can stress less about making your hot tub warmer. 

Heat loss 

Every degree of temperature lost from your hot tub, needs to be made back up by the heater. Wondering how you can reduce heat loss? You'll find the answer in the form of quality hot tub insulation, hot tub covers and the hot tub's location.

Insulation within cabinet 

The most effective forms of hot tub insulation on the market can act like a space blanket or double glazing for windows. As you can imagine, these options have a positive impact on lowering hot tub running costs. 

As an example, Jacuzzi® Hot Tubs have two layers of insulation – one that acts as a core insulator and one that reflects heat trying to escape, it also recaptures heat from pumps and other equipment. This lowers the amount of energy you need to rely on from your integral heater. 

On the flipside, minimal or ineffective insulation will allow heat to escape from the cabinet and adjusting water temperature levels to remain comfortable will impact your power bill. 


A hot tub placed in an exposed area is more likely to need more power to heat and maintain the water temperature than one tucked in a sheltered area near a building.

There are many reasons for this 

-Wind and general elements are more exposed to the surrounds of the hot tub 

-Cool air can come through the base of the hot tub 

-Ambient temperature

What will decrease the running costs of a hot tub?

Now it’s about preventative measures. The things you can do that will help you lower your running costs. This section will cover off three key areas: 



-Electricity suppliers 

-Smart systems  

Hot tub insulation  

Most hot tubs utilise two forms of insulation, material or (SPF) Spray Polyurethane Foam.

For more information on hot tub insulation, different options and what options are most effective, read this article - Best hot tub insulation (Good, better, best). 

Hot tub covers are also an important feature to keep in mind. By choosing a well-insulated and snug fitting cover, you prevent major heat escaping from the top when the hot tub is not in use.

Hot tub temperature  

Various hot tub retailers in the UK speak about the impact that turning your hot tub down by a single degree can have when it comes to the amount of energy used. 

At lower temperatures your heater is not working as hard or as long, to maintain the heat levels required. On average, most people keep their hot tubs at around 38° to 40°. Dropping to just 37° is energy efficient and remains a comfortable temperature for an enjoyable hydromassage. 

Using a smart remote control system 

Smart remote control systems can offer varying services and benefits to a hot tub customer, depending on the brand providing it.  

As an example, Jacuzzi® has the SmartTub® app. Both parts work together so you can remotely control and monitor your hot tub anywhere with a cellular connection. 

The money saving features it offers includes the ability to -

-Personalise your soak sessions. Jacuzzi® Hot Tub will learn how long it takes to heat to your desired temperature at your desired soak time. 

-Place hot tub on vacation mode. By placing the hot tub on pause and keeping water at a lower temperature until you return, you have the ability to save up to 25% on standby heating. 

-Energy usage data. Monitor the exact kWh of your hot tub usage and off-peak, peak energy data.
