Nelson™ Heat Trace Type LT self-regulating heating cable is used in domestic hot water temperature maintenance systems.
It is an energy-efficient and economical alternative to common recirculation systems. The heating cable is used to maintain water temperature in the supply piping system, reducing or eliminating the delay in obtaining hot water at each fixture. This cable system eliminates the need for return piping, pumps, check valves and pressure balancing valves found in recirculating systems. In addition, maintenance requirements are greatly reduced through the elimination of all devices with moving parts connected to the recirculating portion of the hot water supply system.
