This patented heating system for whirlpool bathtubs, spas and hot tubs captures and recycles the waste heat "energy" produced by the pump/motor and delivers that heat to the bath water.  The Thermal Wrap system will maintain water temperature and prevent heat loss caused by the whirlpool action.  The system allows the motor to run cooler; increasing the motors longevity and efficiency.  There are no moving parts and nothing to wear out.  Made in the USA!
