What is Most Energy Efficient Hot Tub?

When shopping for a hot tub many people desire an energy efficient model. If you are considering purchasing a hot tub, you may be concerned about how much your energy costs could increase. The good news is there are plenty of energy efficient models to choose from, while also being very affordable to run. Continue reading if you are interested in learning more about how to select the most energy efficient hot tub.

Choose Eco Modes and Pumps

If you are looking to save energy there are models equipped with eco modes. How it works is the hot tub will operate at a lower temperature when not in use. This reduces the amount of energy consumption. Some models do not have this feature, but you can still use a timer. A timer will reduce the water temperature at certain times when not in use, like overnight. If neither of these options is available, you can always manually lower the temperature whenever you wish to save energy. Overall energy consumption is also affected by the style of pump your hot tub is equipped with. Circulation pumps use less energy than jet pumps – in fact, they can use as little energy as a 40-watt light bulb!

Quality Covers

The most energy efficient models will come with a lockable, heat shield hardcover. This will contain the heat and prevent cold air from cooling down the water in the tub. Look for covers with a tapered design and insulated baffles around the fold.

Adjustable Venting

Something you may not have been aware of is the pump or motor waste can be reused to continue heating the water. This is found in energy efficient hot tub models. This venting will reduce your energy costs all year round. It will trap and vent heat as necessary to maintain your ideal temperature.


Looks aren’t everything when it comes to hot tubs. A sleek design does not mean it is energy efficient. Make sure your hot tub had sufficient insulation. It is an extremely important factor when looking for energy efficient models. Most energy efficient models will be fully insulated providing high density, high-quality insulation, rather than partial coverage.

The Most Energy Efficient Hot Tubs

The CEC (California Energy Commission) approves certain hot tub models to show which ones are the most energy efficient. Be sure to check for their approval! Actually, Hydropool was one of the first CEC approved hot tubs on the market. They have been providing exceptional energy efficiency technology for years now and the CEC models can run for just a few cents per day.

Monthly Costs

Some people prefer to have an estimate on how much their hot tub will cost them on a certain basis. There is a certain formula that can help provide that. Find the wattage of the hot tub model you are interested in, this is usually on the label. Multiply that number by the number of hours you intend to use your hot tub each day. Then divide that number by 1000 and this will determine the daily kilowatt hours for the hot tub. Next is locating your current utility kilowatt rate and multiplying your daily number by 30. This will give you your monthly estimate. Now that you have a good idea of what constitutes an energy efficient model you are ready to start browsing.
