With the ColdZone 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 ColdZone system works with your spa to efficiently lower or raise the temperature quickly.


With the ColdZone 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.


The ColdZone system also helps improve energy efficiency during normal hot tub operation, because it can reduce the amount of time the standard heater runs in order to keep the water hot.


With ColdZone you can chill the water to as low as 60 degrees. For serious athletes, the option to bring the temperature of the water way down can mean soothing relief for muscles after an intense workout.

Hot Tub Cooling Systems

A hot tub is a wonderful thing especially during those colder months of the year, but what about during the hot summer months when sitting in a cool tub can be just as enjoyable? Especially if you live in a part of the country where temperatures are above 100 degrees for several months out of the year? The thing about a hot tub is aside from lowering the temperature on your control system and the ambient air temperature being at or below your set temperature there is no way of cooling a hot tub. In lay terms, a typical hot tub is designed to heat and raise water temperature not cool it. For example, most people use their hot tubs between 100-104 degrees, however, if you want to reduce the temperature to 90 degrees you can adjust it down on your control pad, however, the water will only cool to the ambient air temperature outside so if it is a 100 degree day then the hot tub won’t drop in temperature below that. Hot tub owners have done trivial things like putting in bags of ice to cool the hot tub but that can be tedious and costly not to mention only temporary. Thanks to some innovations in recent years you now have a choice to make your hot tub a cold tub. With the cooling system that Sunset Spas provides we will be able to allow you to use your tub all year around!
