We’ll also highlight some of the best energy efficient hot tubs that we offer, so you can make an informed decision and enjoy your hot tub without breaking the bank.
Let’s dive in!
What Are The Most Energy-Efficient Hot Tubs?
There are a few factors to consider when choosing the most energy-efficient hot tub. The first is the size of the tub. A smaller hot tub will use less energy than a larger one. The second factor is the type of heating system. Electric heaters are more energy-efficient than gas heaters. The third factor is insulation. A well-insulated hot tub will retain heat better and use less energy to maintain the desired temperature.
When it comes to size, a small hot tub that holds two to three people is the most energy-efficient option. If you have a larger family or entertain often, then a medium or large hot tub would be more suitable.
Popular hot tub amenities include jets, lounge chairs, and foot massagers. Another crucial “feature” to take into account when purchasing a hot tub is the cost of operation. A more expensive hot tub could include complete foam insulation, a tight-fitting cover to hold the water temperature and other energy-efficient features.
The hot tub will, however, be less expensive to run over time. In the long run, you will save more money by purchasing a more expensive hot tub. It might seem like a big chunk of money to give at once, but when you do the energy calculation of enjoying this luxury at less cost, it is worth it.
So, in essence, quality construction and building materials, full foam insulation, and a snug-fitting cover that is designed to keep in heat constitute an energy-efficient hot tub.

Why Choose Energy-Efficient Spas?
Investing in energy-efficient spas offers more than just a relaxing soak, it’s a smart choice for your wallet and the environment. These advanced hot tubs, like the most energy efficient hot tubs we’ve highlighted, are designed to minimize power consumption while delivering top-tier performance. By incorporating features like Scandinavian insulation, high-efficiency pumps, and smart heating systems, energy efficient spas significantly reduce monthly energy bills compared to traditional models. Plus, they help lower your carbon footprint, making them an eco-friendly option for environmentally conscious buyers.
Another key advantage is the long-term savings. While the upfront cost of the best energy efficient hot tubs may be higher, their lower operating costs make them the most economical choice over time. For example, models like the Everest Life or Teide Life use very little electricity, as little as around 3 kWh a day (about $0.42 at North Carolina’s 2026 average of roughly $0.14 per kWh), allowing you to enjoy luxurious hydrotherapy without worrying about skyrocketing electricity bills. Whether you’re looking for a compact spa for two or a larger model for entertaining, choosing an energy-efficient spa ensures you get the best of both worlds: comfort and cost-effectiveness.
The Importance of Energy Efficiency in Hot Tubs
Energy efficiency is important for many reasons when it comes to hot tubs. For one, it can save you money on your energy bills. It can also help to prolong the life of your hot tub and make it more efficient overall. Additionally, energy efficiency can help to reduce your carbon footprint and impact on the environment.
When choosing a hot tub, there are a few things you can do to ensure that you are getting an energy-efficient model. First, look for a spa that is built to a recognized efficiency standard, such as the California Energy Commission’s Title 20 rule (the APSP-14 standard) that limits how much standby power a portable spa may draw to hold temperature. Second, ask for the model’s estimated annual operating cost or its measured daily kWh so you can compare tubs on the same basis. Ask your hot tub dealer about any energy-saving features that their models offer.
When a hot tub follows stringent energy guidelines, together with its efficient equipment, the monthly energy cost gets lower. That means that you don’t need to keep the water warm, you can enjoy hot water and save money, too.
The Benefits of Owning an Energy-Efficient Hot Tub
Modern hot tubs use less energy to keep the water at the desired temperature than they would if they had to reheat the entire tub every time it was used. Instead of water cooling down every time you finish soaking, a modern hot tub can save energy by keeping the heat from the water in (with a cover for example) and only heating it up to your desired water temperature when you are ready to use it again.
Pro Insight • Epic Hot Tubs Service Team
“Plenty of owners assume shutting the heater off between soaks is the frugal move. In a well-insulated spa it usually works the other way: holding a steady temperature takes less energy than reheating a tub of cold water every few days. Where you set that temperature matters more than switching things off.”
Understanding Energy Efficiency in Hot Tubs
There are three key factors to consider when choosing the most energy-efficient hot tub: insulation, pump and heater efficiency, and cover quality.
Hot Tub Insulation
A hot tub’s insulation plays a big role in its energy efficiency. Well-insulated hot tubs retain heat better, meaning the pump and heater won’t have to work as hard (and use as much energy) to maintain the water temperature. Look for a hot tub with thick walls and a good seal around the door or lid.
Pump and Heater Efficiency
The pump and heater are the two biggest energy users in a hot tub. Look for models with high-efficiency pumps and heaters that use less electricity to operate.
Cover Quality
A good hot tub cover helps retain heat and protects against weather damage when not in use. Be sure to choose a cover that fits snugly on your hot tub and is made of durable material that will last for years.
Pro Insight • Epic Hot Tubs Service Team
“When someone calls us about a power bill that suddenly jumped, the tub itself is rarely the culprit. Nine times out of ten it is the cover: waterlogged foam, a warped hinge seam, or a lid that looks closed but is not sitting flush. Heat pours out of the water line all day, and the heater quietly runs to keep up. Lift your cover once a season; if it feels twice as heavy as when it was new, it is done insulating.”
Hot Tub Energy Consumption Ratings
When it comes to energy efficiency, all hot tubs are not created equal. In fact, there can be a big difference in the amount of energy that different models use. That’s why it’s important to check the energy consumption ratings of any hot tub you’re considering before making a purchase.
In terms of specific energy consumption ratings, you’ll want to look for a model that has an Energy Star rating. This means that it meets strict guidelines set by the US Environmental Protection Agency (EPA) for energy efficiency. Models with this rating will use less electricity than those without it, so you’ll save money on your running cost of a hot tub in the long run.
One thing to know: ENERGY STAR does not assign a numeric rating to portable hot tubs, so there is no such thing as an “Energy Star rating of 3 or above” for a spa. The standard that actually applies to portable electric spas is the California Energy Commission’s Title 20 rule (the APSP-14, now ANSI/APSP/ICC-14, standard), which caps the standby power a spa may draw to hold its temperature. In practice, the most reliable signs of an efficient hot tub are full-foam insulation, a high-efficiency circulation pump, and a snug, well-fitting cover.
When comparing different models, make sure to look at their annual operating costs as well as their initial purchase price. The initial cost may be higher for an Energy Star-rated hot tub with superior energy efficiency, but its lower operating costs will save you money over time. Choose the model that makes the most financial sense for you and your family in the long run.
Energy-Efficient Hot Tub Technologies
When it comes to energy efficiency, there are a few features that you should look for in a hot tub. Let’s discuss some of them down below:
Advanced Insulation Materials
Advanced insulation materials are key to maintaining the heat in your hot tub. There are many options on the market, but not all of them are created equal.
Polyurethane foam insulation is one of the most popular options for hot tubs. It is effective at keeping the heat in and is also very affordable. The dense foam core and foam design will help keep the spa water hot.
Another option is closed-cell spray foam insulation. This type of insulation is slightly more expensive than polyurethane foam, but it is even more effective at keeping the heat in. A hot tub can even have foam on the entire interior of the spa structure, making it an ultra-energy-efficient foam.
Variable Speed Energy Efficient Hot Tub Pump
If you’re looking for an energy-efficient hot tub pump, a variable-speed model is a great option. These pumps can operate at different speeds, which means they use less energy when the hot tub isn’t in use. Additionally, variable speed models are often quieter than other types of pumps.
Energy-Efficient Hot Tub Heater
There are two main types of heaters: gas and electric. Gas heaters are more efficient than electric heaters, but they can be more expensive to operate. Electric heaters are less expensive to operate, but they are not as efficient as gas heaters.
Automated Covers and Heat Retention
One of the most important features to look for in an energy-efficient hot tub is an automated cover. A good cover will help to keep the heat in, which means that your hot tub will use less energy to maintain the temperature you want.

How to Choose an Energy-Efficient Hot Tub
In order to be absolutely sure that you choose the hot tub for your family, which will also be energy efficient, you need to consider several things on your checklist. So, as we mentioned before, you need to evaluate your specific needs. Smaller families require smaller hot tubs as not many of you will use it at the same time. However, if you have a large extended family that you like to entertain, you might benefit from a larger swim spa energy efficient, of course.
Another thing to keep in mind is the budget. Hot tubs and swim spas can get pricey, so you need to be aware of how much you can spend so that you don’t get carried away with the glitz and glamour of hot tubs on the shop’s floor. Make sure the salesperson is aware of your budget limitations (both initial and monthly) so that they can adequately help you.
When you’ve discussed the budget, you need to know where your new hot tub will go. Depending on the location and the space available, you’ll be able to choose something that is well thought through and not bought on a whim only to be an eyesore later on.
Last but not least, compare energy consumption ratings and use the energy calculator to get an idea of what individual energy consumption will be.
Extra Tips for Maximizing Hot Tub Energy Efficiency
To keep your new hot tub energy efficient and working for longer, you’ll need to be a devoted user. You’ll need to do proper maintenance on the hot tub, like:
- Check the water balance twice a week
- Use bromine or chlorine for hot tub
- Clean the filter twice a month
- Every three to four months, clean, drain, and refill the spa
- The spa cover should be aired twice a week
- For the spa to stay full, add water as needed
Pro Insight • Epic Hot Tubs Service Team
“The cheapest efficiency upgrade is not a gadget, it is a clean filter. A clogged filter forces the pump to run harder and longer to move the same water, and that shows up on your bill before it shows up as a problem. Rinse it every couple of weeks and your pump does less work all year.”
Seasonal adjustments are also necessary. You don’t want to be overheating the hot tub during the summer, so the water temperature should be set at around 85 degrees Fahrenheit. Although the ideal water temperature for a hot tub is anywhere between 100-102 degrees Fahrenheit (with 104 degrees being the maximum it can go), you can keep it at around 97-99 degrees Fahrenheit in the winter. As it is cool outside, the water will need more time to heat up. As for the ‘How long does a hot tub last?’ question, that entirely falls on proper maintenance.
Summary
With the right information and research, you now know how to choose a hot tub that is the most energy-efficient in 2026. You should take into consideration factors such as size, features, cost, warranty coverage, and of course energy efficiency when making your decision. Utilizing this guide as a starting point is an excellent way to narrow down your choices and find the perfect energy efficient hot tubs for sale that will fit both your lifestyle and budget!
