nVent RAYCHEM HWAT-P1 self-regulating electric heat trace cable is designed to provide hot water temperature maintenance in 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.

Additional information for RAYCHEM HWAT-P1:

  • System is UL Listed, CSA Certified, and FM Approved in nonhazardous locations.
  • Can be used with Copper, CPVC and rigid PEX (1/2 in–2 in) piping
