The nVent RAYCHEM HWAT self-regulating heating cables maintain the desired water temperature in a building’s hot water distribution pipe network.


Positioned on the pipe underneath the insulation, the cables automatically compensate for pipe heat losses where they occur, thereby providing continuous, energy efficient, hot water temperature maintenance.



The HWAT system can be used to eliminate the re-circulation system altogether or to help optimise it’s performance, in a hybrid approach.In a hybrid system, recirculation loops are used on the long central pipe runs, with HWAT cables installed on all branch run outs.
Either way, a much improved solution when compared to re-circulation systems.
