“Thermal Creep”
Cal Spas are designed with energy-ecient components and systems that are meant to sustain heat generated
by the equipment, which is then cycled back into the spa water. In hot weather or in situations where the spa is
set to extended run times, Thermal Creep may occur. Thermal Creep is a condition where the measured water
temperature can be higher than the set temperature. To manage Thermal Creep you may:
Vent your cover. This means placing a folded cloth about ¾” (2cm) thick under all four corners of the cover
before you lock the cover down.
Open your cover. Opening the cover at night will also quickly cool the water down if desired.
Open all air controls. Set your ltration cycles to run during the cooler times of the day or night.
Reduce the length of your lter cycles.
Visit your local dealer for additional guidance.
Since Thermal Creep only occurs in well-insulated hot tubs, it is not indicative of something that is wrong with
your spa or its equipment.
