J-345™ ENERGY EFFICIENCY

 

Through extensive experience, Jacuzzi® has perfected our approach to creating the world's most energy-efficient spas. Utilising industry-leading technology and innovative multi-layered insulation, we set the standard for energy-saving hot tubs.

​

Unlike all other brands, Jacuzzi® can factually and accurately tell you the exact average running cost for any of our models using exclusive SmartTub® technology.

​

All our hot tubs undergo rigorous testing by the California Energy Commission (CEC), which has found that, on average, our hot tubs are 22% more efficient than the strict standards they set.

​

Our SmartTub® app allows us to get actual real-world usage data of J-345™ users:

​

•  Average kWh per day = 5
•  Average temperature = 38°
•  Number of hot tubs tracked = 37
 

*All C temperatures are rounded to the nearest whole degree. This information was taken over 2 years from UK Jacuzzi® Hot Tubs connected to SmartTub® energy monitoring. The data shown is the median measure and is based on the sample size shown.
