A hot tub is excellent for relaxation and unwinding. One issue that could arise with hot tubs, however, is high energy consumption and the resulting impact on costs and the environment.

Fortunately, there are ways to lower energy consumption and keep it manageable. We cover 6 such tips in this article.

6 Tips To Save Energy On Your Hot Tub

1. Use a spa cover or a thermal blanket.

Covering the hot tub when not in use will stop the water from evaporating and trap heat. It means the pump and the heaters won’t have to work as hard to refill the water and heat it, saving you a lot on energy utilization.

A good spa cover should work just fine since most modern spa covers come with sufficiently insulated shells. An even better option is a thermal blanket.

2. Set a lower temperature if possible (based on comfort).

Did you know that the cost of energy consumed to maintain the temperature of water increases approximately 10-30 percent (varies based on external factors like the climate) for each degree rise in the temperature?

That means it will cost you much more to maintain the water temperature in your hot tub at 40° C than it will to keep it at 39° C.

Most hot tubs come with a default setting of 40° C. If you’re comfortable at lower temperatures, like 38° C for example, change the settings and lower the temperature to reduce energy consumption.

3. Plan for prolonged disuse.

If you’re not going to be using the hot tub for more than five to seven days (if you’re going on a vacation, for example), turn the temperature setting to low or switch off the thermostat.

If the weather is calling for very cold temperatures, and there is the possibility that the water could freeze, don’t turn off the thermostat because frozen water will damage the pipes. Just lower the temperature instead. If the climate is warm enough, you can reduce the temperature or switch off the thermostat.

4. Go easy on the blowers.

A blower injects a jet of air into the water which creates a soothing effect for people in the hot tub. Blowers, however, consume a lot of energy.

Energy consumption happens in two ways. Firstly, energy is consumed by the pump that has to run for the blower to work. And secondly, because air at a lower temperature is being introduced the water cools and the heater has to work harder to increase the temperature.

The longer you use blowers, the more energy will be consumed. So use them wisely.

5. Clean and maintain the filters.

It takes the motor and heating elements more effort to circulate water through dirty or clogged filters, increasing energy consumption.

Performing regular maintenance activities will ensure your hot tub has clean filters so that no energy is wasted. It will also increase the longevity of your hot tub and keep it running smoothly for longer.

6. Minimize water spillage.

The final tip we have for you is to make sure you do not wastewater. When you splash around and spill water from the hot tub, the pumps kick in to maintain the level of water. Since the newly introduced water is at a lower temperature, the heater works harder to heat the tub so that the temperature is maintained at your preferred level. The result is higher energy consumption.

Of course, a hot tub is for you and your family/friends to relax and have a good time, so you don’t have to be too stringent. It’s just a matter of awareness – the less water wasted, the lower the energy consumption.


There you have it, 6 ways how you can reduce the costs of using your hot tub and also ensure the impact on the environment is low.
