There are several ways to keep your hot tub cool during the summer. It is pretty easy to do and has proven effective in helping cool the temperature down.

1. Use Hot Tub Jets

The hot tub air jets will lower the hot tub temperature. Cooler water tends to sink, whereas warm water rises to the surface. You may combine warm and cold water by utilizing the jets and swirling the water. As a result, the water becomes cooler and is heated more evenly.

If you plan to use your hot tub, start the jets 10 minutes before that. Although it does not directly, it blends the warmer and cooler parts of the water, leading to a more balanced water temperature that isn’t too hot.

2. Lower The Temperature Setting

It is also pretty easy to just adjust the temperature and achieve a cool tub. This will work nicely if the preferred setting is below the average temperature outside. However, this may be ineffective if you reside in a particularly hot climate. Cooling can take some time when the average air temperature is similar to the desired water temperature.

Another method for decreasing the temperature of your hot tub is to set it to economy or sleep mode. Most hot tubs have economy or sleep modes intended to save energy. It also aids in significantly reducing the temperature of a hot tub, especially during the summer.

3. Reduce Filter Cycles

During the warm season, cutting back on your filtration times might also help keep your hot tub from being too hot. When you have achieved a cool tub temperature, just don’t forget to return the filter settings to their original setting.

You may also be able to program the times that filtering takes place with some hot tub control systems. Altering the filter settings to run during cooler hours of the day can also be beneficial.

4. Use Cold Objects

Utilizing cold things to cool the water is a unique approach to consider. Given the amount of water in a hot tub, the impact is not as significant as you might assume. 

It is simpler to do if your hot tub is smaller. Before entering your hot tub, use cooling mats or put frozen water in gallon milk jugs. You can quickly lower the temperature using this. However, this is just a temporary solution.

5.  Move Hot Tub To A Different Location

You can either relocate your hot tub to a covered or shaded location or make your shade with a sizable umbrella. You should try this approach because it will reduce the hot tub’s temperature enabling your hot tub so be a cold spa.

6. Hot Tub Chiller

If you’re out of alternatives or will be cooling your hot tub frequently, a chiller might be worth considering.

They are usually available at your neighborhood pool supply store or online. They will undoubtedly assist you in keeping the temperature bearable during the hotter months. In some instances, you can even easily reach 60 F allowing you to use your hot tub as ice baths.

Frequently Asked Questions

Here are some frequently asked questions to guide you on how to cold down a hot tub in summer.

Why Hot Tubs Overheat During Summer?

To reduce operating expenses, hot tubs are built to hold as much heat as possible. But in the summer, you might notice that your hot tub warms up a few degrees beyond the setting you selected

This is frequently referred to as “Thermal Creep,” where the hot tub’s temperature keeps rising since there is nowhere for the heat to go.

The electric motors of hot tubs are the most common cause of overheating. These circulate water around the hot tub to heat, filter, and power the jets. When an electric motor starts running, it produces heat. The heat emitted is then transmitted into the hot tub water, increasing it above the desired temperature.

This is overplayed in the summer heat because hot tub owners usually run the hot tub at a lower temperature. In fact, it is not uncommon for a hot tub to heat up to 25 – 30 C just from the motors and without even turning on the heater.

How Do I Stop My Hot Tub From Overheating?

The thermostat may be set too high, which is an obvious cause of overheating. See if lowering the hot tub’s temperature to 98F helps to make the water cool. The cover can also resolve the problem by pouring cold water and adjusting the hot tub’s filtration cycle.

What Happens When Hot Tub Is Too Hot?

Because the water in a hot tub is hotter than your usual internal body temperature, staying in one for too long can cause overheating and symptoms such as light-headedness, dizziness, or vomiting.

Can I Use My Hot Tub As A Pool In Summer?

Yes, you can. Just don’t heat it.  That’s all. It’s safe to soak your body as long as you sanitize the water and circulate it like a hot tub.
