How to Cool Down a Hot Tub in Summer: Top Tips for Refreshing & Relaxing Soaks

How to Cool Down a Hot Tub in Summer?

To cool down a hot tub in summer, there are two main approaches: using a hot tub chiller or employing DIY methods.

A hot tub chiller can be purchased and installed by a professional HVAC technician, pumping chilled water through the hot tub to lower the temperature to about 60°F.

DIY methods include creating shade using an umbrella, adding frozen water-filled containers to drop the temperature by a few degrees, and adding cold tap water to reduce the temperature by about 5°F.

It is important to ensure that the hot tub is not completely turned down, as this can disrupt normal filtration and purification cycles.

Key Points:

Did You Know?

1. Did you know that the concept of hot tubs originated in ancient Rome, where they were called “hippobathra”? The Romans would fill these large wooden tubs with hot water and then cool them down by adding ingredients like snow or ice.
2. In the 1960s, the first hot tubs were made of oak barrels, similar to those used for aging whiskey. These unique hot tubs were favored by hippies and became known as “wine barrel hot tubs.”
3. If you want to cool down your hot tub in summer, consider adding a natural and refreshing touch by infusing it with herbs. Cooling herbs such as peppermint, lavender, or spearmint can be placed in a mesh bag and then submerged in the water. This not only provides a cooling effect but also adds a delightful aroma to your hot tub experience.
4. For a more innovative approach to cool your hot tub, you can use a misting system. These systems dispense a fine mist of water over the tub, helping to lower the temperature and create a pleasant cooling effect. It’s a fantastic solution to beat the summer heat while enjoying your hot tub.
5. For a truly unique way to cool down your hot tub, consider utilizing solar-powered cooling systems. These systems use solar panels to generate energy, which is then used to power fans or cooling mechanisms that circulate air or water to naturally cool down the hot tub. It’s a sustainable and energy-efficient way to enjoy your hot tub in summer while keeping it refreshingly cool.

Lowering The Temperature Using The Hot Tub Panel

During the scorching summer months, it is crucial to have a hot tub that provides a refreshing experience, rather than feeling like a boiling cauldron. Luckily, most hot tubs are equipped with a temperature control panel, allowing you to adjust the water temperature to your preference. However, it is worth mentioning that even on the lowest setting (usually around 60°F), the water may not reach a sufficiently cool temperature when it’s warm outside.

  • Hot tubs come with a temperature control panel for adjusting water temperature
  • The lowest setting is typically around 60°F
  • Water may not reach cool temperatures on the lowest setting during hot weather

Remember, maintaining a comfortable water temperature in your hot tub is essential for an enjoyable experience.

Using Sleep Or Economy Mode To Cool Down The Hot Tub

If lowering the temperature through the hot tub panel is not sufficient in cooling down your hot tub during the summer, consider these alternative modes to help alleviate the heat:

  1. Sleep mode or economy mode: Switching the hot tub to these modes is a great option. They are specially designed to lower the temperature more effectively than the standard mode.

By activating sleep or economy mode, you can maximize energy efficiency while also achieving a cooler and more comfortable hot tub experience.

  • Switch to sleep or economy mode for more effective temperature reduction
  • Maximize energy efficiency while enjoying a cooler hot tub experience.

Considerations For Hot Tub Chillers In Warm Areas

For individuals residing in areas with unusually warm temperatures, where summer temperatures can persist for long periods, investing in a hot tub chiller can be a smart decision. A hot tub chiller functions much like an air conditioner, using refrigeration to circulate chilled water throughout the hot tub, effectively reducing its overall temperature. These chillers can be easily obtained from local pool supply stores or online, and they have the ability to cool the water to approximately 60°F, offering a pleasant and revitalizing respite from the scorching summer heat.

  • Key benefits of a hot tub chiller include:
  • Provides relief from high temperatures
  • Enhances the overall enjoyment and comfort of using a hot tub during the summer months

A hot tub chiller operates similarly to an air conditioner, utilizing refrigeration to pump chilled water through the hot tub, effectively lowering its overall temperature.

Remember to always consider your specific needs and regional climate before making any purchase decisions. Stay cool and enjoy your hot tub even in the hottest of days!

Additional Tips For Lowering Hot Tub Temperature

There are several methods you can use to reduce the temperature of your hot tub during hot weather:

  • Create shade around your hot tub using an umbrella or other shade-providing structures. This can help mitigate the direct sunlight hitting the hot tub, preventing unnecessary heat absorption.

  • Freeze water in empty containers, such as gallon milk jugs, and place them in the hot tub a few minutes before use. This can drop the water temperature by a few degrees, providing some relief from the heat.

  • Consider adding cold tap water to your hot tub if it features a built-in water supply, such as a tap. This can lower the temperature by approximately 5°F. Keep in mind that hot tubs can still be used with therapy jets at any temperature without causing damage, so you can still enjoy a soothing soak even when the water is not at its hottest.

Hot Tub Handbook And Video Course For Maintenance And Savings

Maintaining a hot tub, especially during the summer months, can be a daunting task. To help you navigate these challenges more efficiently, Swim University offers a comprehensive hot tub handbook and video course. This resource provides valuable tips on maintenance, water purification, and saving money on chemicals. With their expert guidance, you can keep your hot tub in optimal condition while also enjoying all the benefits it has to offer throughout the summer season.

Methods For Reducing Hot Tub Temperature In Hot Weather

In addition to the aforementioned tactics, there are a few other effective methods you can implement to lower the temperature of your hot tub during hot weather. Firstly, consider turning down the temperature setting on your hot tub panel to a level below 85°F. This adjustment can make a notable difference in temperature, depending on your location. However, it is crucial to be patient as dropping the temperature of a hot tub takes longer than raising it.

Another key strategy is to take advantage of the sleep and economy modes available on many hot tub models. By utilizing these modes, you can further decrease the temperature and increase energy efficiency. For instance, let’s say your hot tub is currently set at 104°F. By switching to sleep mode, you could potentially lower the water temperature to around 97°F. However, keep in mind that as the outside temperature cools down, these modes may become less effective. For instance, during the cooler fall months, you may need to switch back to the standard mode to maintain a comfortable temperature.
