Before homeowners buy a hot tub, they often ask a big question: How much electricity does a hot tub use? The answer to this question depends on several factors, from the type and size of your tub to the climate you live in. In this article, we’ll break down everything that affects your hot tub’s energy use and how you can manage it wisely.
High Energy Hot Tub Components
Though they may seem simple on the surface, hot tubs actually use several electrical components together that work to heat, circulate, and filter the water in the tub. Each component plays its own role in the total energy your hot tub uses:
- Heater: Usually the biggest energy draw, ranging from 1,500-6,000 watts depending on voltage and the size of your tub.
- Pump & Circulation System: These are the parts that move water through filters and jets, usually consuming between 1,000 and 2,000 watts while active.
- Air Blower: Some models have an air blower, which helps make the water extra bubbly and relaxing by injecting air into it.
- Lights: Many hot tubs have extra features like lights, so you can enjoy the tub no matter the time of day.
- Control System: Even when you’re not actively using it, the control panel of your tub uses a small amount of standby electricity.
Each of these parts working together helps keep your hot tub clean, comfortable, and ready to use.
110V vs. 220V Hot Tubs & Their Differences
Most hot tubs are powered by either a 110-volt or 220-volt setup.
110V hot tubs plug into a standard household outlet. While convenient, they often heat water slowly and can lose temperature during heavy use, since they can’t run the heater and jets at full power at the same time.
220V hot tubs require a dedicated electrical line to be run to them and must be installed by a licensed electrician. Though the setup is more complicated, these hot tubs heat faster and maintain temperature much better than 110V hot tubs, especially in colder weather. Naturally, they often use more electricity than 110V tubs, since their components are more powerful.
Estimating Your Monthly Bill
If you want to estimate your monthly bill, use this simple formula:
Monthly Cost = Daily kWh x local rate x 30 days
For example, if your hot tub uses 6 kWh per day, and your local electricity rate is $0.18 per kWh, your monthly cost would be:
Monthly Cost = 6 kWh x $0.18 x 30 days = $32.40
Keep in mind that your daily electric usage can vary depending on the season, how often you use your hot tub, and your temperature settings.
Factors That Determine The Cost
Beyond the components themselves, there are several additional factors that influence how much energy your hot tub uses each month:
- Temperature Settings: Every degree counts – setting your hot tub just a few degrees lower can make a big difference in energy use.
- Quality & Insulation: The build of your hot tub determines how efficiently it retains heat. Better insulation results in less heat loss, and therefore less work for your heater. A high-quality cover with proper sealing also helps maintain temperature.
- Size & Water Volume: Larger tubs hold more water, which will naturally take more time and energy to heat fully.
- Frequency of Use: If you plan to use your hot tub daily, this will require more frequent reheating, filtration, and jet use.
- Outdoor Conditions: Your climate makes an impact on your energy use. Cold air, wind, and humidity all impact how hard your hot tub has to work to sustain its temperature all day long. If you live in a particularly cold climate zone, your tub will spend more energy maintaining higher temperatures.
Energy-Saving Tips for Hot Tub Owners
Owning a hot tub doesn’t automatically equal a high electric bill. These simple tips can help you reduce energy use without sacrificing comfort:
- Use a High-Quality Cover: A tight-fitting, well-insulated cover does a better job of keeping heat in and debris out. This can reduce the toll on your heating pump and your filters throughout the year.
- Lower the Temperature When Not in Use: If you’re not actively using the tub, consider dropping the water temperature a few degrees to save energy. This will especially make a difference in colder temperatures, where keeping your tub at its maximum setting around the clock will drive up your energy costs.
- Engage in Regular Maintenance: Cleaned filters, proper chemical balance, and well-maintained pumps will help your hot tub run as efficiently as possible.
- Check for Leaks or Gaps: Even tiny leaks or gaps around jets can make your heater work harder. To avoid wasting energy, check often for potential damage.

FAQ’s
How Much Power Does a Hot Tub Use?
Hot tubs can use anywhere between 1,500-6,000 watts when heating and 1,000-2,000 watts when the pumps are engaged. In total, they can use anywhere between 3-7.5 kWh of electricity per day, depending on your exact voltage, frequency of use, and insulation quality.
How Can I Lower My Electrical Bill While Having a Hot Tub?
Most experts recommend using an insulated cover, lowering the temperature when not in use, and keeping your equipment well-maintained to reduce your hot tub’s energy costs.
Is it More Efficient to Keep a Hot Tub on All the Time?
No, it is usually not more energy efficient to keep your hot tub running 24/7. For most homeowners, it’s better to let it cool slightly during days when it is not in use, then reheat it a bit before your next soak. However, it could be more efficient to keep it running continuously if you use your hot tub daily.
What Temperature Should I Keep a Hot Tub at When Not in Use?
Many homeowners lower the temperature in their hot tubs to around 95°F when they’re not actively in use. Then, you can raise the temperature back up between 100-102°F when you’re ready to get in.
