With the CoolZone™ system, you can heat and cool the water – something not possible in most spas. Enjoy a cool dip during the day and a hot bath later in the evening in your spa HotSpring. The CoolZone™ system works with your spa heater to efficiently increase 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 on a hot summer day. As a result, you’ll enjoy your hot tub more often throughout the year.

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 to keep the water warm. Depending on where you live, this increase in efficiency has the potential to result in real savings over time.

Cold water therapy
With CoolZone™ you can cool water up to 15 degrees. For serious athletes, the option to lower the water temperature can provide soothing relief for muscles after an intense workout.
