Warm or cool - it's your choice!

With the CoolZone System, you can heat and cool the water — something that is not possible with most spas. Enjoy a cool dip during the day and warm soak later that night. The CoolZone system works with your spa’s heater to efficiently raise the temperature in just a few hours.

Use your hot tub more!

With the CoolZone system, your hot tub becomes a cool place for the kids to swim and play during the day or a place for you to relax and unwind after working in the yard on a hot summer day.

Energy-efficient flexibility

The CoolZone system also helps improve energy efficiency during normal hot tub operation, because it can reduce the amount of time the standard No-Fault® heater runs in order to keep the water hot.

Cold water therapy - as low as 16ºC

With CoolZone you can chill the water to as low as 16ºC. For serious athletes, the option to bring the temperature of the water way down can mean soothing relief for muscles after an intense workout.
