7 Minute Read


There are many things you will want to educate yourself about when you’re considering your next hot tub purchase. While size, brand reputation, model, jet configuration, technology, and hot tub cost are all very important factors of your selection, you’ll also want to consider the electricity usage aspect of your hot tub purchase and how that will impact your budget once you get your hot tub home. You may wonder: “How much electricity does a hot tub use?” In this article, we’ll help you get to the bottom of this question.


Read on to learn about some of the important factors that will impact the answer to this question.


It’s important to keep in mind that electricity usage is dependent on a number of factors such as weather, hot tub quality, and energy efficiency of the hot tub. This is largely based on energy used to heat the hot tub and circulate the water. A nominal amount of energy is also used for the hot tub’s lighting. Interestingly, 75 percent of a hot tub’s energy expenditure is consumed when the hot tub is covered and not being used. Several factors, including size, usage time, and insulation, can influence the electricity usage of your hot tub.


Electricity is used to power the hot tub, including running the jets, heat, circulation and lights. While utility costs vary, estimates in California Energy Commission ratings suggest many major brands of hot tubs cost approximately $10-21 per month to run, with the average cost of electricity on the most efficient models coming in at $15 or less per month. However, keep in mind that reheating water can significantly elevate the energy bill, especially in colder climates.

What factors impact the electricity use of a hot tub?

Once again, there are many variables that will affect the electricity usage of your hot tub, whether it is a Jacuzzi® model or another brand. Here are a few questions that you can ask yourself that will help you determine your energy usage and what you can expect your running costs to be:

  • How long will I use my hot tub for?
  • How often will I use my hot tub?
  • What size hot tub do I have or do I want?
  • What is the weather like where I live?
  • Does my hot tub have good full foam insulation?
  • Does my hot tub have efficient pumps?
  • Is my hot tub compatible with a smart system that helps manage energy use?
  • Does my hot tub meet or exceed energy efficient standards?
  • What temperature will I keep my hot tub water?
  • Where will my hot tub be placed?
  • Are there energy efficient models available that can reduce electricity usage?

Energy efficiency is a crucial part of Jacuzzi® hot tub craftmanship. Every Jacuzzi® hot tub exceeds California Energy Commission standards for stand-by power consumption. Much emphasis is also placed on good insulation. Jacuzzi® hot tubs have high-quality insulation that helps retain the heat of your hot tub water, thus reducing energy usage and, ultimately, your electricity costs.


Can smart technology affect my electricity use?

Beyond excellent insulation, smart technology compatible with your hot tub can make all the difference in managing your hot tub electricity use. For example, the Jacuzzi® SmartTub® system helps you monitor and manage your energy usage, providing the opportunity for you to schedule and adjust your hot tub’s energy use to suit your needs. You can even customize your water temperature and lighting, and even lock your hot tub at the touch of a button through the Jacuzzi® SmartTub® system app. This automation can reduce your standby power usage by up to 25 percent. Additionally, the circulation pump plays a significant role in overall energy usage, as it operates continuously alongside the heater. Using your hot tub during off peak hours can also lead to reduced electricity rates due to lower demand on the electrical grid.
