How to Save on Your Hot Tub Electric Bill

The energy it takes to heat the water in your hot tub can be a drain on your finances and your area's resources. The biggest energy costs involved in maintaining a hot tub are raising the water temperature and sustaining the heat, so you can conserve energy by improving the tub's insulation and adjusting the temperature wisely. Not only will you save money on your electric bill, but you'll also be living a greener, more environmentally friendly lifestyle.


Adjust the hot tub's thermostat down a few degrees. Hot tubs are automatically set to 104 degrees Fahrenheit, but you won't miss the extra heat if you dial it down to 101 or 102 degrees instead. The hotter the water already is, the more energy it takes to increase the temperature further, so this small adjustment can make a big difference.


Turn off the hot tub heater when you're away. If you're going to be away during freezing weather, either leave the heater on at a low temperature or winterize the tub and pipes before you go.


Talk to your electric company representative about off-peak hours. The company might offer lower rates on electricity usage during certain times of the day. If so, heat your hot tub during these hours, then cover it until you're ready to use it.


Invest in a good-quality hot tub cover, especially if your current cover is showing signs of wear. A cover in good condition seals heat in, the way insulation does in your home. If your cover is heavy and waterlogged, replace it immediately.


Place a floating thermal blanket under the cover to reinforce the insulation. These blankets also protect the covers, extending their lifespan and making them less likely to become waterlogged.


Replace the hot tub's filters every year. Clean them with a commercial filter cleaner every three to four months. This keeps the pump working efficiently and reduces wear on the motor, so the system uses less energy.


Plant shrubs or install fencing or other windbreaks around the hot tub. These reduce the wind chill factor on the water and help maintain the water temperature.


Turn off any air jets, bubble blowers and unnecessary spa lights when you finish using the hot tub. Cover the tub tightly. Leave some lights on for safety, especially if you have small children.
