How Much Does it Cost to Run a Hot Tub in 2023?

First things first: On average, how much does it cost to run a hot tub in 2023? The answer is wide-ranging and complex (more on that later). On average, though, homeowners can expect to pay between $20 and $75 a month to run and maintain their hot tub. 

Of that, between $20 to $50 can be attributed exclusively to energy costs. In other words, newer hot tub models average around a dollar a day in energy to run a hot tub, while older and less energy-efficient models cost more. 

Factors That Affect the Cost of Running a Hot Tub 

The past few years have seen a boom in the hot tub industry, as homeowners have shifted their focus toward renovation. Hot tubs have become a popular alternative to installing a full-size swimming pool. While the initial investment in a hot tub might be a significant consideration, it's equally important to understand the ongoing operational costs associated with running one. Let’s take a look at the factors that might affect the answer to the question: How much does it cost to run a hot tub? 

Energy Efficient Hot Tub Features

One of the primary factors influencing the cost of running a hot tub is its energy efficiency. Modern hot tubs are designed with energy-saving features such as high-quality insulation, advanced pump and heating systems, and efficient circulation mechanisms. Investing in a well-insulated hot tub with energy-efficient components can significantly lower your monthly energy bills. 

Additionally, newer models often incorporate programmable timers and smart technology that allow you to optimize heating and filtration schedules, further reducing energy consumption. Investing in a hot tub with a smartphone app enables users to set timers, adjust heat settings, and fully control their hot tub from their mobile device.

At Wellis, we are always striving to create the most energy-efficient spa on the market. Whether it’s our signature polyfoam insulation on the side cover and subfloor or our thermal covers, our features are designed to keep energy costs to a minimum.

Size and Water Volume

The size of the hot tub directly impacts the cost of operation. Larger hot tubs have a larger water volume, which means more water needs to be heated and circulated, and more chemicals may be needed to treat it. 

Consequently, they might require more energy to maintain the desired temperature and water quality. When choosing a hot tub, consider your space availability, usage needs, and budget constraints. Opting for a size that aligns with your requirements can help you manage operational costs effectively.

Heating and Filtration

Heating and filtration are integral to maintaining the water quality and temperature of your hot tub, and ensuring it lasts for as long as possible. The cost of heating depends on a wide variety of factors like the local climate, desired water temperature, and insulation, but quality manufacturing may introduce energy-efficient heating systems that can mitigate those costs. These can be more expensive upfront but can lead to substantial long-term savings.

Filtration systems play a crucial role in keeping the water clean and safe. High-quality filtration systems might require less maintenance and use less energy to keep the water crystal clear, so you don’t have to sacrifice sanitization for savings. UV-C systems like those used in Wellis Spas, for example, treat the water in the hot tub several times a day, all while using minimal power and helping keep the water clean between cycles. 

Climate and Seasonal Variation

The local climate and seasonal variations have a significant impact on the cost of running a hot tub. In colder climates, the hot tub will need to work harder to maintain the desired water temperature, resulting in higher energy consumption during the winter months. 

It's important to consider these variations when budgeting for operational costs throughout the year.

Usage Patterns

Your usage patterns will also influence the cost of operating a hot tub. As you might have guessed, if you use it frequently the hot tub will require more energy to maintain the desired conditions.

On the other hand, if you use it less frequently, you can adjust heating and filtration schedules to save energy during periods of non-use.

Maintenance and Repairs

Regular maintenance is essential to keep your hot tub running efficiently. Neglecting maintenance can lead to more energy consumption and higher repair costs in the long run. Addressing minor issues promptly and conducting routine checks on the hot tub's components can prevent larger, costlier problems from arising.

Energy Efficiency of Your Home

Your home's electrical wiring can impact how much it costs to run a hot tub. If you have inefficient systems or bad outlets, it may cost more on average to run a hot tub.

Energy costs also vary depending on your location and the type of energy sources available to you. Electricity and natural gas are common energy sources for heating hot tubs, but researching local energy rates and comparing the costs of different energy sources can help you choose the right one for you and estimate the ongoing expenses.

Water Chemistry and Chemicals

In addition to maintaining the spa itself, maintaining proper water chemistry is crucial for the longevity of your hot tub and the health of its users. Regular testing and adjustment of water chemistry, as well as the use of chemicals such as chlorine or bromine, contribute to operational costs. However, efficient management of water chemistry can prevent more significant problems down the line and ultimately save you money.

By choosing an energy-efficient model, maintaining proper maintenance routines, and being mindful of usage patterns, you can strike a balance between enjoying the benefits of your hot tub and keeping operational costs manageable.

What to Look For When Buying a Hot Tub

“How much does it cost to run a hot tub” is just one question buyers should ask themselves when shopping for their spa. The other? What features should I look for when I’m shopping that might lower costs in the long run? The answer encompasses the type of hot tub, its size, insulation, energy efficiency features, local energy rates, and how well it's maintained. 

Generally, smaller and more energy-efficient hot tubs tend to be cheaper to run. Here are some types and features to consider when aiming for an energy-efficient and cost-effective hot tub:

Inflatable Hot Tubs Vs. Regular Hot Tubs

Inflatable hot tubs are generally cheaper to purchase upfront, which can sway some buyers in their direction. When it comes to running costs though, inflatable options often have less insulation and can be more difficult to maintain, making them more costly in the long run. 

Hot Tub Size 

Smaller hot tubs require less water to heat, which can lead to lower energy costs overall. 

When picking out your hot tub, consider a model that gives you plenty of room to relax and entertain, but isn’t too much larger than what you really need. Check out some of the most popular hot tub sizes we offer here at Wellis, or browse our full hot tub buying guide:

It's a good idea to research different models, read reviews, and consult with hot tub professionals to find the best option that suits your budget and energy efficiency goals.

How to Save Money When Running a Hot Tub

Now that you know what to look for when making your purchase, let's delve into some smart tactics to help you keep your hot tub running efficiently without breaking the bank. 

These tips can help lower your monthly budget when considering, “how much does it cost to run a hot tub”?

Optimal Temperature Settings

While the idea of keeping your hot tub at a toasty temperature might be tempting, the reality is that higher temperatures require more energy to maintain. 

Set the water temperature at a comfortable level rather than excessively high. Aim for a range between 80°F to 85°F (27°C to 29°C) for a good balance between comfort and energy efficiency. Also, consider using a pool cover when the hot tub is not in use to trap heat and prevent evaporation, which can help maintain the water temperature without constant heating.

Regular Maintenance

Proper maintenance is crucial for keeping your hot tub running efficiently. Regularly clean the filters, as dirty or clogged filters can force the system to work harder, consuming more energy. Keep the water balanced and sanitized to prevent the growth of bacteria, which could lead to equipment damage and higher maintenance costs in the long run. By following a consistent maintenance schedule, you can ensure that your hot tub operates optimally and lasts longer.

Off-Peak Energy Usage

If your local utility offers off-peak electricity rates, consider running your hot tub during these hours. Off-peak hours usually occur during the late evening and early morning, when overall energy demand is lower. 

Running your hot tub during these times can result in lower energy costs due to reduced electricity rates. Some hot tub control systems even allow you to program heating and filtration cycles to coincide with off-peak hours automatically.

Monitor Water Level

Keep a close eye on the water level in your hot tub. A lower water level can cause the pumps to work harder, leading to increased energy consumption. Ensure that the water level is maintained within the manufacturer's recommended range to prevent strain on the system and unnecessary energy expenditure.

Use Solar Heating

If you live in a sunny area, consider harnessing solar energy to heat your hot tub. Solar heating systems can be integrated with your hot tub setup, reducing the reliance on traditional electric or gas heating. 

While the initial investment for solar equipment might be higher, the long-term savings on energy bills can make it a cost-effective choice in the grand scheme of things.

Mindful Usage

Encourage mindful usage among family members and guests. Remind everyone to minimize splashing and unnecessary water turbulence, as this can lead to heat loss through evaporation. Also, establish guidelines for water activities that might increase debris accumulation, such as eating or drinking while in the hot tub, to avoid overworking the filtration system.

How many years does a hot tub last?

A hot tub can last between five and 20 years or more. A spa's lifespan is based on both the quality of the spa itself and the way it is maintained.

If you invest in a quality hot tub and keep up with regular maintenance throughout its life span, you may be able to enjoy your hot tub for decades. 

Should I leave my hot tub on all the time? 

Yes! While it comes as a surprise to many, it is actually best to leave your hot tub on all the time. Hot tubs are meant to be kept on, though they should be switched to energy-saving modes if and when it is available. 

It is more cost- and energy-efficient to keep your hot tub at or near the ideal temperature than it is to turn it off and attempt to reheat it to that temperature a few times a month. If you are going to be away for a few months at a time, it’s often a better idea to lower the temperature and engage in an energy-saving mode, to avoid having to reheat the entire tub when you get back. 

Plus, keeping it running will keep the water circulating and allow the filtration systems and pumps to do their jobs.
