nVent RAYCHEM HWAT self-regulating electric heat trace cable is designed to provide hot water temperature maintenance for domestic hot water supply pipes in commercial and residential structures. The heat trace cable is installed on the hot water supply pipes (underneath standard pipe insulation) and replaces supply-pipe heat losses at the point where the heat loss occurs, thereby providing continuous, energy-efficient, hot water temperature maintenance and eliminating the need for a recirculation system. Since the heat trace cable utilizes RAYCHEM's self regulating technology, the cable adjusts its power output to compensate for variations in water temperature and ambient temperature. That means it produces more heat if the temperature drops and less heat if the temperature rises. Combining the HWAT heating cable with the HWAT-ECO controller provides a flexible hot water temperature maintenance system that will both compensate for installation variations and provide adjustable temperature set points to maximize energy efficiency.

Other possible benefits of installing a RAYCHEM HWAT System include:
Simplified Design - Single-pipe HWAT systems eliminate the need for designing complex recirculation systems, with their pumps, piping net-works, and complicated flow balancing.
Low installed cost - Installation of the HWAT system is simple. The electric heat trace cable can be cut to length, spliced, tee-branched, and terminated at the job site, reducing installation costs. Also, fewer plumbing components are needed; recirculation piping, pumps, and balancing valves are all eliminated.
