This patented heating system for whirlpool bathtubs and spas captures and recycles the waste heat energy produced by the pump/motor and delivers that heat to the water. The Thermal Wrap system will maintain water temperature and prevent heat loss. There are no moving parts and nothing to wear out! Made in USA.
