Do Hot Tubs Use Electricity?

Yes, the majority of hot tubs in the market use electricity as an essential element for their operation and maintenance. Electricity powers various functions of a hot tub, including heating systems, jets, lighting, and control panels. The heating element uses electricity to warm the water, while jets and lights require electrical power for their functionality. Additionally, the control panel, which allows users to adjust settings and features, relies on electricity to operate.

How Do You Work Out The Cost Of Running A Hot Tub?

Determining the exact cost of operating a hot tub can be challenging due to fluctuating energy prices. To calculate the cost at the time of reading, you’ll need to take into account:

  • The current electricity rate per kilowatt-hour (kWh).
  • The daily energy consumption of your hot tub.

These factors will allow you to estimate the cost of running your hot tub based on your specific circumstances and the prevailing electricity prices.

How Does Jacuzzi® Know The Electricity Usage For Their Hot Tubs In The Uk? 

The SmartTub® system facilitates the measurement of electricity consumption for Jacuzzi® Hot Tubs. This ingenious technology accumulates data from hot tub users globally, encompassing various behaviours such as draining, refilling, and even usage on snowy days.


What Is SmartTub®?

SmartTub® is an innovative system exclusively designed for Jacuzzi® Hot Tubs. It is a smart and interconnected platform that enables users to remotely control and monitor their hot tubs from anywhere as long as there is a cellular connection. SmartTub® not only offers convenient control over your hot tub’s settings and plays a pivotal role in measuring the average kilowatt-hour (kWh) usage. This data is invaluable for understanding and managing the energy consumption of your Jacuzzi® Hot Tub, ensuring an efficient and cost-effective hot tub experience.

Does Hot Tub Energy Consumption Fluctuate Throughout The Year? 

Hot tub electricity costs can indeed fluctuate between summer and winter. Much like how your central heating system consumes more energy during colder months and less during the summer, hot tubs follow a similar pattern. During the winter, when the air temperature is lower, hot tubs require more energy to maintain the desired water temperature, leading to higher electricity costs. In contrast, when the surrounding air is warmer in the summer, less energy is needed to keep the water temperature consistent, resulting in lower electricity costs.

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

What Factors Influence Hot Tub Energy Costs?

You might be pondering, what influences the daily energy usage of my hot tub, and how might it deviate from the 6 kWh data point? Consider the following factors:

  • Climate: Warmer climates require less energy for heating, while colder ones demand more.
  • Hot Tub Placement: Sheltered locations reduce vulnerability to weather-related energy losses.
  • Water Temperature: Higher water temperatures necessitate more energy.
  • Drain and Refill: Emptying, refilling, and reheating the hot tub incur additional costs.
  • Hot Tub Usage: The more you use jets and lighting, the greater the energy consumption.
  • Time of Day: The national average electricity price fluctuates with demand.

What Features Of A Jacuzzi® Hot Tub Contribute To Reducing Energy Costs?

Jacuzzi® Hot Tubs in the UK incorporate several energy-saving features to help reduce operational costs:

Hot Tub Insulation:

Depending on the collection, Jacuzzi® Hot Tubs feature varying insulation types. The J-200™ models utilise EcoShield insulation, which includes polystyrene slabbing and a foil backing along with an Astrofoil space blanket. All J-200™ hot tubs exceed the standards set by the California Energy Commission. The J-300™ and J-400™ collections have full foam insulation and an insulating SmartSeal® foil blanket, further enhancing energy efficiency.

ProStream™ Circulation Pump:

Jacuzzi® Hot Tubs use the ProStream™ circulation pump, designed for energy efficiency. It maximises water flow while consuming a low amount of energy. This pump can be set to an energy-efficient mode, and filtration settings can be adjusted to clean the water without relying on the jets, further saving energy. Note used on J-300 / J-400 collection.

Pump to Jet Ratio:

Properly designed pumps ensure that only the necessary number of jets are powered, preventing energy wastage.

ProLast™ Cover:

Exclusive to Jacuzzi® Hot Tubs, ProLast™ covers feature a heat seal on the underside to prevent heat loss. These covers are filled with dense insulating material, effectively trapping heat in the water and making them more resilient against various weather conditions.

Jacuzzi® SmartTub®:

The SmartTub® system offers features for energy conservation and monitoring, including:

Smart Heat Mode:

Allows scheduling hot tub usage, providing energy savings estimates, similar to a programmable timer for home heaters.

Smart ModeVacationMode:

During extended periods away from home, this mode cools the water to a level where necessary filtration cycles can still run, reducing standby heating costs by up to 30%.

Energy Usage Reports:

Provides insights into energy consumption, allowing users to monitor their hot tub’s energy usage over specific periods.Smart Tub Interface

Up to 6-Stage Filtration System:

Depending on the hot tub model, Jacuzzi Hot Tubs feature a comprehensive 5-stage filtration system that captures large and small debris, clarifies the water, and purifies it using ozone gas and a UV-C bulb. How does this help save on energy? This reduces the need for chemicals and allows the water to be used for longer, minimising the frequency of draining, refilling, and reheating.

These features collectively contribute to energy efficiency, helping Jacuzzi® Hot Tub owners in the UK reduce energy costs while enjoying the benefits of their hot tubs.
