The cost to run a hot tub depends on different factors including the size of the tub, its energy efficiency, the climate in which it is located, and how often it is used. While we can’t give you an exact number, on average, the monthly cost to operate a hot tub ranges from $20 to $50.

How Much Electricity Does a Hot Tub Use?

The amount of electricity used depends on the size, age and condition, desired temperature, environment, and insulation of your hot tub. The primary cost associated with running a tub is the electricity required to heat the water. The water heater uses the most amount of resources, anywhere from 1,500 watts for a smaller tub to 7,000 watts for a larger one. The second component that uses a lot of energy is the water pump, using anywhere up to 1,500 watts.

Contrary as it might sound, it’s less expensive to leave your hot tub on all the time as opposed to periodically turning it on and off. It’s more economical to keep your tub at a constant temperature, than it is to heat it up from a cold start on a regular basis which uses a lot of energy, particularly if you use it frequently. If you’re going to be away for a few weeks, you can turn your temperature down, or consider draining it completely if you don’t plan to use it for an extended period of time. 

Energy prices vary and some areas charge more during peak periods and less during off-peak hours, so it’s best to look up the rates for your area, get the wattage and approximate energy usage specs from your dealer and do the math. If your hot tub has a circuit timer, you can set it to run during off-peak hours. The type of climate you live in will also influence the amount of electricity consumed; warmer climates will use less electricity compared to those in colder climates. 

How to Reduce Hot Tub Running Costs

One of the easiest ways to reduce the cost of your hot tub and increase its longevity, is to keep up with its maintenance, particularly the filters. A dirty filter doesn’t allow water to easily pass through making your pump work harder which uses more energy. Luckily cleaning your filters is easy, just run them under water every week and soak them in a chemical cleaning solution every few weeks to keep them free of build up and debris. 

Insulation affects how quickly heat will leave the water of your hot tub and how much energy you will need to keep it warm. Make sure to choose a spa with energy-efficient foam insulation to preserve heat, especially if you live in a cold climate. Make sure to always use a well fitted cover when your tub is not in use, which also helps keep out dirt and critters. Additionally, installing specific landscaping can help shield your spa from the elements and maintain its heat better.
