How Much Does It Cost to Run a Hot Tub: Daily, Monthly & Yearly Expenses

The average cost to run a hot tub is nearly $500 per year. Most homeowners can expect to pay around $300 and $1000 on an annual basis, including electricity and maintenance. The electricity cost to run a hot tub is about $20 and $50 per month and $240 and $600 per year. However, how much it costs to run a hot tub will depend on different factors, such as hot tub size, maintenance, repairs, heating and filtration system, climate, and temperature. 

Jackery Solar Generators can help you lower the overall cost of running household appliances such as hot tubs, heaters, lights, filtration systems, etc. The solar-powered generators ensure a steady electricity supply to the appliances whenever there is a power outage in the area. These essential home backup solutions are portable, so you can easily carry the solar generator outdoors and power appliances.

Key Takeaways

• Hot tubs typically use between 3000W to 7500W per hour, depending on how often you use them and how well they retain heat.
• A well-insulated hot tub with a tight-fitting cover will retain heat more efficiently, reducing the need for frequent reheating.
• The cost of running a standard hot tub can significantly vary depending on your area's utility rates, making location a key factor in total expense.
• Using a Jackery Solar Generator can supplement your energy needs, lower your electricity bills, and provide backup power during outages.

How Many Watts a Hot Tub Consumes

A hot tub typically consumes between 1500W - 6000W per hour and is used for about 30 - 45 minutes every day. When calculating the wattage consumption of a hot tub, you will need to check the power consumption of two main elements: the heater and the circulation pump. 240V hot tub heaters can draw around 6000W, whereas 120V heaters require 1500W per hour. The circulation pump typically needs around 1500W of power. The total power consumption can vary between 3kWh to 7.5kWh per day.

How Much Does It Cost to Run a Hot Tub in the USA?

The cost to run a hot tub can be easily calculated by multiplying the power consumption and electricity rate in the area. For instance, if you have a 120V hot tub (3000W) that runs for 30 minutes per day and the electricity rate per kWh is 15.95 cents per kWh, the cost to run a hot tub will be $0.24 per day and $7.18 per month. The yearly cost to run a hot tub will be equal to $86.13. 

On the other hand, if you own a 240V hot tub (6000W) that runs for 30 minutes and the electricity rate per kWh is 15.95 cents per kWh, the cost will be around $0.47 per day and $14.35 per month. The yearly cost will increase to $172.26. However, the hot tub's running cost will increase if the usage is more than 30 minutes.

Daily, Monthly, and Yearly Cost to Run a Hot Tub

Official Tips to Reduce Hot Tub Costs

When it comes to reducing the cost of a hot tub, you need to analyze ways to conserve energy. Here are some simple measures to help insulate the hot tub and improve its efficiency:

Block the Wind

Whenever the frigid winter wind hits the water in the hot tub, it can lower the temperature, which in turn increases the cost of electricity bills. To prevent this, you can consider using strategic fencing, windscreen, or well-placed shrubbery to block the wind.

Invest in a Solar Generator

Solar-powered generators can help you power the heater and circulation system in the hot tub. They use free sunlight to generate electricity, which makes them ideal for reducing monthly electricity bills. Jackery Solar Generators are robust home battery backup solutions that can power most household appliances, such as hot tubs, heaters, refrigerators, lights, etc., to reduce bills.

Use a High-Quality Cover

If your hot tub is not in use, consider keeping it covered to prevent the heat from escaping. You can invest in a high-quality cover or a thermal blanket to surround the entire hot tub and insulate the whole unit. 

Use Heaters During Off-Peak Hours

Electricity rates are usually higher in peak hours compared to off-peak hours. That's why it is better to schedule the hot tub heater either early in the morning or later in the evening when the electricity rate is low. However, the exact off-peak hours will depend on the season and time zone.

Close the Jets

If you are not using the hot tub, make sure to shut off the air controls for the jets. This helps maintain the temperature and pH, which uses less energy and fewer chemicals.

How Much Does It Cost to Run a Hot Tub FAQs

How much does it cost to run a hot tub per month?

The monthly cost to run a hot tub varies but generally ranges anywhere from $60 to $100. The exact electricity cost depends on several factors, like the hot tub size, efficiency, and the electricity rate per kWh.

Is it cheaper to keep a hot tub on all the time?

Yes, it is generally cheaper to run a hot tub continuously rather than turning it on and off frequently. This is because the heater needs to expend more energy to heat the water from scratch each time while maintaining a constant temperature.

Can I turn my hot tub off at night?

While you can turn off the hot tub at night, it is generally not recommended. Keeping the hot tub running even at a lower temperature will lead to lower electricity costs in the long run.

How much will an inflatable hot tub raise my electric bill?

The impact of an inflatable hot tub on your electric bill depends on usage and weather. On average, an inflatable hot tub uses between 3.5 and 6 kilowatt-hours (kWh) per day, but this can vary widely. If the electricity rate in your area is 15.95 cents per kWh, the monthly electricity bill will increase by $16.74 - $28.71.
