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 or spa 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!

Thermal Wrap Snaps Over Motor

Tub water circulates through a serpentine path in the Thermal Wrap, collecting the heat generated by the pump/motor and recycles that heat to the tub water - were it belongs!

Retro-Fit Kits: available for new or existing spa motor(s).
The "Thermal Wrap System" will compliment your electric heater by capturing the waste heat generated by your pump motor and delivering that heat to the tub water, saving you money with heating costs.  The Thermal Wrap will help maintain water temperature during normal filtering and heating cycles and while using your spa in high speed jet action.
