How much does it cost to keep a hot tub running all the time?

9 Minute Read

When you’re considering the joy and relaxation that a hot tub can provide, one important factor to consider is the ongoing cost of keeping it running. The price of maintaining a hot tub is not always a straightforward number—it varies based on several factors. These factors include the hot tub’s size, energy efficiency, insulation, frequency of use, and the climate where you live.

This article will address this topic so you can have a better understanding of the costs involved and the strategies you can use to keep those operating costs as low as possible.

Article highlights:

The average monthly cost of running a hot tub can range between $20 to $50, or even less for the most energy efficient hot tubs.
However, there is not an exact cost for running your hot tub, as this number will rely on, and fluctuate, based on a variety of factors.
Tips for keeping your hot tub running for less.

The base cost of running a hot tub

To understand how much it will cost to keep your hot tub running all the time, it’s important to examine the components that contribute to your energy bill. For example, the primary sources of energy usage are:

Heating the water: Keeping the water at your preferred temperature, typically between 100°F and 104°F, requires constant energy.
Filtration: Hot tubs have filtration systems that clean the water, usually running multiple times a day.
Jets and pump motors: When the jets are activated, the pumps require energy to circulate the water.

On average, the monthly operating cost of a hot tub typically falls between $20 to $50 per month in electricity. This is for general maintenance, heating, and occasional use. For a better estimate, it’s helpful to look at the specifics of your hot tub.

For example, the California Energy Commission ratings report electricity costs for hot tubs from major brands, such as Jacuzzi® Hot Tubs, typically range between $10 to $21 per month to operate. The more energy-efficient the hot tub, the lower your rates may be. Highly efficient hot tubs, for example, can lower monthly operation costs to $15 per month or even less. Keep in mind that electrical costs are also dependent on the kWh rates in your area and how often you use your hot tub.

Key factors affecting hot tub running costs

Size of your hot tub

The size of your hot tub plays a significant role in total energy consumption. Larger hot tubs need more energy to heat and circulate the water, which equates to higher electricity usage. Smaller hot tubs or tubs designed for fewer people, such as two to four bathers, tend to be more energy-efficient than larger tubs built for six or more people, for example.

Energy efficiency

Energy efficiency is a major factor in reducing the ongoing cost of running your hot tub. Newer models are generally more energy-efficient due to advances in technology. If your hot tub is not energy-efficient, the costs of heating and maintaining water temperature may be higher.

Insulation

Good insulation is a critical factor in helping to keep your energy costs low. Hot tubs that are poorly insulated will lose heat more quickly, requiring more energy to maintain your desired temperature. High-quality insulation around the tub and in the cabinet can significantly reduce energy consumption. All Jacuzzi® Hot Tubs, for example, exceed the California Energy Commission Standards for spa energy consumption due to their high-performance energy-saving insulation that completely surrounds the shell and fills the cabinet. This lowers operating costs, ensures quieter operation, and is reliable event in the coldest of climates.

Climate and weather conditions

Speaking of climates, the region in which you live also has an influence on the cost of keeping your hot tub running. If you live in an area where the temperature drops significantly, your hot tub will have to work harder to keep the water warm, especially in winter. On the other hand, in warmer climates, your hot tub won’t need to work as hard to maintain a consistent temperature, so you may find your operation costs are lower.

Frequency of use

How often you use your hot tub impacts energy consumption as well. If you use your hot tub daily, or if you keep it heated 24 hours a day seven days a week, it will cost more. On the other hand, if you only use it a few times a week, and you lower the temperature when it is not in use, your overall cost will be reduced.

Covering your hot tub

Keeping your hot tub covered when it’s not in use can greatly reduce the need for additional heating and also keep your operating costs down. A high-quality, well-fitting cover will help retain your hot tub water’s heat and protect the water from cooler outside temperatures. Without a cover, your hot tub will lose heat faster, and more energy will be required to keep the water warm.

Energy-efficient hot tubs: A wise long-term investment

If you’re looking to save money over time, it’s worth considering a high-quality, energy-efficient hot tub. The investment in a more energy-efficient model might come with a higher initial cost, but the ongoing savings can be substantial. Overtime, a higher-quality model with energy-saving features will pay for itself not only financially, but in freedom from stress and hassle of maintenance, too.

What makes an energy-efficient hot tub?

Better insulation: High-quality energy-efficient hot tubs, such as Jacuzzi® Hot Tub models, are built with superior insulation. This helps your hot tub maintain its temperature more effectively, while minimizing heat loss and reducing the need for frequent reheating.
Advanced filtration and circulation systems: Efficient filtration systems help maintain the water while using minimal energy. These systems operate on cycles, so the pumps and motors don’t run continuously, which also helps save on electricity costs.
Low-consumption jets: Many newer hot tub models come with energy-efficient jets. They offer all the benefits of a full hydrotherapy experience without requiring as much power as older models.
Energy-saving modes: Many modern hot tubs are equipped with settings that allow you to lower the temperature or reduce filtration times when your hot tub is not in use. This is especially helpful when you’re traveling or won’t be using the hot tub for an extended period of time.

Brands and models

Some of the most energy-efficient hot tubs on the market today come from well-known brands like Jacuzzi® Hot Tubs, which is recognized for producing high-quality tubs with exceptional energy efficiency. Jacuzzi® Hot Tubs feature built-in thermal insulation, energy-efficient pumps, and superior heaters designed to reduce energy consumption while still providing a superior, luxury experience you expect from the Jacuzzi® family of products.

Tips for keeping operating costs low

Even if you already own a hot tub or are thinking of purchasing a model that isn’t the latest in energy-saving technology, there are still several ways to cut down on the ongoing costs of running your hot tub.

Invest in a high-quality cover

One of the most effective ways to keep energy costs down is to invest in a high-quality, well-fitting hot tub cover. A good cover helps retain your hot tub water’s heat, reducing the need for constant reheating. Covers are especially important in cooler climates where heat loss can be significant. Look for covers that are insulated, easy to use, and designed to fit snugly. Make sure the hot tub cover you purchase is compatible with and made to fit your hot tub model. The right fit will make all the difference.

Use the “economy mode” or “sleep mode”

Many hot tubs have energy-saving modes, such as “economy” or “sleep” mode, which lower the temperature while your hot tub is not in use. If you plan to use your hot tub intermittently, setting it to a lower temperature when not in use can make a substantial difference in your monthly energy bill. When you’re ready to use it again, you can heat it back up.

Maintain proper water chemistry

Keeping the water chemistry balanced can improve the efficiency of your hot tub’s filtration system. If the water is too acidic or alkaline, it can cause the filtration system to work harder than necessary, which will require the use of more energy. Regularly testing and adjusting the water’s pH, alkalinity, and sanitizer levels ensures your filtration system runs efficiently.

Check for leaks and maintain regular inspections

Ensure that there are no leaks in your hot tub, as even a small leak can cause the system to run inefficiently. Also, regularly check the pumps, jets, and filters to ensure they are working properly. Overworked or broken equipment can result in unnecessarily higher energy usage.

While it may seem convenient to keep your hot tub running all the time, overall it’s generally not necessary and can increase your energy costs. Keeping your hot tub running continuously will use more energy to maintain the desired temperature, especially if you’re not using it regularly. It’s recommended to lower the temperature or even switch to an economy mode when not in use, as this will reduce energy consumption without compromising your hot tub’s ability to reach its ideal temperature when you are ready for a soak. Regularly turning the temperature down and heating it back up when needed can be a more cost-effective option. However, if you use your hot tub frequently or prefer to always have it at the perfect temperature, keeping it running at a lower setting could still be more efficient than constantly reheating it from a cold start.

The ideal solution to this is the Jacuzzi® SmartTub® System, an innovative technology designed to help you maintain your hot tub while keeping operating costs low. This system allows you to control and monitor your hot tub remotely through a smartphone app, so you can adjust settings, such as temperature and filtration cycles, based on your schedule and usage patterns.
