Ideal Hot Tub Temperature When Not In Use


Just like there’s ideal water temperature, there’s also ideal hot tub temperature when not in use. It is crucial to adjust the temperature to prevent excessive energy consumption. Keeping the energy a bit lower can save you a lot of money.

But, keep in mind that turning the hot tub off is not recommended because it may take more energy to heat it again. A good rule of thumb states that the temperature should be at least 5 degrees lower when not in use. In this article, we will guide you through everything you need to know about the hot tub temperature in summer.

Hot Tub Temperature When Not in Use Guide

Lowering the temperature of your hot tub when it is not in use can be beneficial in many ways. It works great if your main concern is saving energy. But, there are some other things you can use this method for. However, some tub owners might find it difficult to achieve the perfect hot tub temperature in summer.

The general rule of thumb suggests that lowering the temperature for at least 5 degrees can help significantly. This is necessary depending on the climate. It will keep the water warm enough for quick heating when needed. But, if you are not going to use the tub for a longer period (more than a week), it might be better to further lower the temperature.

Ideal Indoor Hot Tub Temperature

Normal hot tub temperature is 102-104 degrees. You should lower the temperature to 97-100 degrees when the hot tub is not in use, or if you plan on not using it for a week. On the other hand, if you will leave it unused for more than a week, lower the temperature to 92-94 degrees.

Ideal Outdoor Hot Tub Temperature

If you live in warm weather, leave your outdoor tub temperature at 92-94 degrees. Just make sure you securely attach the hot tub cover so no water evaporates. On the other hand, if you live in colder weather, keep the temperature at 97-100 degrees. You must never go lower than 90 degrees because pipes can freeze during winter.

Ideal Inflatable Hot Tub Temperature

Inflatable hot tubs should be kept at 99 degrees when not in use. Setting the heaters to this temperature is ideal for these kinds of hot tubs because it saves energy. Just make sure you have a good supply of hot tub chemicals. Having enough sanitizer will make sure your hot tub stays safe and hygienic.

Adjusting Hot Tub Temperature Benefits

If you lower the temperature, your hot tub will need more time to reheat. But, it turns out that spending a few hours to reheat the tub is most likely worth it. Reheating the water does not use the same amount of energy your tub would spend to maintain the high heat over a prolonged period.

Also, you will save on chemicals because chlorine will last longer if the water is cooler. Adjusting the temperature will:

Save You Time for Hot Tub Reheating

It is enough to simply lower the temperature by about 5 degrees. This small change will make it much easier to return to the desired temperature. Turning it off completely means you have to generate much more heat when you turn it on again because you are starting from scratch.

Consequently, this leads to more energy consumption so it is generally not recommended. Also, you will have to wait for a long before the temperature rises to the desired level. Lowering the heat will make it easy to avoid this problem.

Prevent Energy Waste


Lowering the hot tub temperature in summer is much more cost-efficient. You will not have to use so much energy to heat your tub. Raising the temperature to 5 degrees is much easier than heating colder water. It also means this method uses much less energy.

You should bear in mind that the time used to heat your tub relates to energy consumption. So, if you wait longer to reach the perfect temperature, you will also spend more money on energy. If you lower the temperature by only 5 degrees, you will reach the optimal water conditions in no time. This means you won’t have to wait for long before you climb the hot tub steps and enjoy.

Protect Your Hot Tub

Some people turn their tubs off completely during the winter. However, this can be very risky because the pipes can burst. Also, water in your tub may freeze so this can lead to more complicated problems. That is why it is important to know how you can handle this situation.

To avoid these problems, do not turn off your hot tub. Instead, keep the water temperature at least 5 degrees lower than usual. Doing this will not only save energy but also help you maintain the tub most appropriately. Also, this method will prevent possible damage to your hot tub.

If you are wondering about the perfect hot tub temperature when not in use, you can follow the rule of thumb. According to it, the temperature should be at least 5 degrees lower than usual. However, experiment with it to see if you can go lower than that. This saves energy, protects your hot tub system, and saves you time when reheating.

Adjusting the temperature of your hot tub when it is not in use is crucial when it comes to saving energy. Lowering it for at least 5 degrees can prevent energy waste, protect your hot tub, as well as save time for reheating.

Lower your indoor hot tub temperature to 97-100 degrees. You can lower your outdoor hot tub temperature to 92-94 degrees if you leave in hot weather, but make sure you never go lower than 90 degrees if you leave in cold weather. Lastly, keep your inflatable hot tub temperature at 99 degrees.
