Energy-Efficient Hot Tubs

If you’re in the market for a hot tub, you may be concerned about how owning one might impact both the environment and your utility bills. Fortunately, there are plenty of hot tub models available that prioritize energy efficiency in all aspects of their design.

But what sort of features should you look for in energy-efficient hot tubs, and how can you know the model you choose is both eco-friendly and high quality? Take a closer look at what makes a hot tub energy efficient.

What Makes a Hot Tub Energy Efficient?

Designing a hot tub to be energy efficient requires a comprehensive approach. Nearly every aspect of the spa plays a role in reducing its energy needs in some form or another. Those aspects include the following:


Perhaps the most important aspect of energy-efficient hot tubs is the way that they’re insulated. Insulation traps heat in the tub and maintains the water temperature, which allows the spa’s heating system to use less energy overall.


EcoWrap™️ Insulation from Sundance®️ Spas offers superior quality insulation that can help your spa retain its heat even on the coldest days of winter.


High-quality cabinetry can offer convenience to you as a hot tub owner, but it can also reduce heat retention if it’s not designed with energy efficiency in mind. It’s important to make sure the model you select has great insulation in its cabinets if you want to lower those energy bills and remain eco-friendly.

Energy-efficient hot tubs from Sundance®️ Spas use a three-layer Rigid Bond shell to provide highly effective insulation as well as incredible durability. Instead of the standard fiberglass shell you’ll find on many spas, Rigid Bond is made out of a proprietary polyester resin blend that is eight times stronger.


Insulation and quality cabinetry can help retain the heat in your hot tub’s water, but if the source of that heat is not built for energy efficiency, then you’re still going to be consuming a lot of electricity. You want a hot tub that offers a modern heating system designed to do more with less.

Sundance®️ Spas 220V models offer just that. Paired with their Rigid Bond construction and EcoWrap insulation, the efficient heating systems in these hot tubs can help you save money and reduce your environmental impact.


Not all hot tub covers are created equal. They may all do a good job of keeping dirt, debris, and other foreign objects out of your spa, but that’s not the only purpose a good cover can serve. Hot tub covers are also made to trap heat and prevent your spa from burning too much energy, and certain covers do a far better job of it than others.

SunStrong Premium Spa Cover

SunStrong™️ Premium Spa Covers are marine-grade vinyl covers from Sundance® Spas that are made with heat-retaining, high-density foam to provide you with both incredible protection and energy efficiency. On top of the notable energy efficiency these covers offer, they’re also incredibly lightweight.

Smart Technology

Even the most energy-efficient hot tubs can still become wasteful if their owners aren’t careful to manage their energy use. You don’t want to run your tub for too long, and you don’t want to keep it hotter than it needs to be. You also don’t want to run it with parts that need to be replaced and are working inefficiently.

With the SmartTub®️ system, you can avoid all of these issues. This easy-to-use technology allows you to connect to your hot tub through an app on your smart device.

Smart Heat Mode learns your usage and lets you control how much energy you use. With this technology, you can control your spa’s features remotely to reduce unnecessary energy use, closely monitor your usage, and receive alerts when something needs to be repaired.

Other Considerations

While choosing an energy-efficient spa will go a long way in your efforts to reduce your environmental impact, there’s still more you can do to improve that efficiency. Keeping your filters clean and replacing them every three to four months is key, as is being conscientious about how often and how long you run your tub.

Energy-Efficient Hot Tubs Are a Win-Win

Keeping these factors in mind can help you choose the perfect energy-efficient hot tub for your home. With an energy-efficient hot tub, you can both save money on energy bills and reduce your environmental impact — a win-win for all.
