Self Regulating Heat Trace Cable

Self Regulating Heat Trace Cable

Self-Regulating Heat Cable is commonly used for freeze protection of water and drain lines, and for protecting residential and commercial roofs and gutters from ice dams. The temperature rating is for the heat cable’s outer jacket and has nothing to do with the actual temperature of the cable. For most residential applications, you will choose the low temperature cable, as most water lines in the home never exceed 150 degrees.
