PRODUCT FOCUS—Energy Efficient Caldera Spas Leave Your Money In Your Pocket

  • 1

Hot tub manufacturing has come a long way since the early ‘70s when the product first made its way into backyards across the country. One advancement that’s especially important to shoppers today is energy efficient technology. An efficient and well-insulated hot tub can save a homeowner thousands of dollars over the life of the hot tub, so it’s an important purchase consideration.

Often the best place to research the cost of owning a hot tub is from actual owners. Consider what these Caldera® spa owners have said about the energy efficiency of their Caldera hot tub:


“I live in Reno which is very cold during the winter and I keep my spa at 101 degrees year around with very little difference on my electric bill. I use my tub daily and would highly recommend a Caldera Spa to anyone who is in the market for a spa.”
Cantabria® owner, Reno, Nevada


“This is our third hot tub, and the first that is so efficient. We hardly noticed a rise in our electric bill when we installed it. It is easy to maintain, and oh, so relaxing.”
Geneva® owner, Taylors, South Carolina


“I was particularly concerned about energy costs. This spa was located at a mountain cabin, with relatively cold winter temperatures… As an engineer, I can say I am particularly impressed with the efficiency of Caldera.”   
Martinique® owner, Western North Carolina

Think about it. If your hot  is not properly insulated, that heat, and the money you spend to generate it, goes right into thin air.

How Can I Keep Hot Tub Energy Costs Low?

Interested in keeping operating costs low? Here’s what we recommend:

1. Buy a Caldera® Spa

At Caldera, we’ve concentrated on bringing energy efficient design and innovation to all aspects of a spa and we’ve looked at each and every component from the cover to the pump to see how we can make improvements. We recognize that energy efficiency is more than just an environmental concern. It’s a performance advantage that can have a huge impact on a hot tubs monthly operating costs, especially in winter months. Those savings add up, month after month, year after year.

Caldera Hot Tub Insulation.

The real revolutionary, energy-efficient innovation in a Caldera spa comes from our FiberCor® insulation. Available only from Watkins Wellness, the makers of Caldera Spas, FiberCor has four times the density of the urethane foam used in most other hot tub brands. It’s a loose, wool-like fiber that fills all voids and gaps in our hot tub compartments for better insulating efficiency than any other hot tub brand.

FiberCor is also 100 percent non-petroleum based with no VOC emissions. So not only does it improve the efficiency and performance of your hot tub, reducing energy costs, it’s also environmentally-friendly.

Caldera Energy Efficient Pump and Hot Tub Heater.


We’re especially proud of the innovation that resulted in our exclusive EnergyPro® pump and hot tub heater in our Utopia® and Paradise® Series spas. Many spas run jets throughout the day to circulate water and bring the water back up to a set temperature, but that cycling process uses a great deal of energy.

The EnergyPro hot tub pump operates continually at very low wattage, maintaining the temperature you’ve set so that the spa is always ready to use while actually reducing heater use. That’s because 80 percent of the energy used to operate the pump is transferred to the water as heat. It’s a small but efficient change that adds up to substantial savings over time.

2. Make Sure Your Hot Tub Replacement Cover is a Custom Fit

Caldera hot tub covers are designed to precisely fit our spas for maximum energy efficiency. They form a tight seal that locks in heat. Each of our hot tub covers contains an efficient, full-foam insulation wrapped in a durable, marine grade vinyl.

3. Buy and Use A Hot Tub Cover Lifter

With a hot tub cover lifter, the cover hinges back away from the spa, making it easier to maintain in good condition. Without a spa cover lifter, a cover can become scuffed or torn and the insulation can be damaged, resulting in heat loss and higher energy costs.

A hot tub cover lifter makes it much easier to both open and close your hot tub. This makes it more convenient to use your hot tub and will motivate you to use it more often. With such an easy way to close your hot tub correctly it is more likely people will be sure to close the cover after using your hot tub.

How much electricity does a hot tub use per month?

Energy consumption varies per hot tub model and brand. We know that energy consumption is a critical factor in choosing the right and best hot tub model. That’s why we concentrate on manufacturing highly energy efficient hot tub models.

How much will my electric bill go up with a hot tub?

Energy costs vary from place to place, depending where you live. Average daily temperature is also a factor in calculating monthly energy costs. And of course, your Caldera hot tub will use more energy when it is in use than when it is idol. Hot tub massage jets turn off when your hot tub is not in use. The more you use your hot tub naturally the higher your electricity costs will be.

You should expect that your electricity bill for running a hot tub in winter months, especially in colder climates, will go up. This is another of the many reasons we put such a concentration on engineering products with hot tub insulation that works to keep the heat in your hot tub from dissipating into the environment.

Many Caldera owners report that in using their hot tubs an average of once a day, 6 days a week while making sure they properly recover their spa when finished, that their electric bills did not rise more than $20. per month.

We believe we’ve created some of the most energy efficient hot tubs on the market today, and we’re proud to offer a performance advantage that benefits you month after month, year after year.

A certified Caldera dealer in your area can tell you what their own customers are reporting in regards to monthly electricity costs for their Caldera spa.
