![]() If doing this place the heat trace control thermostat directly onto the pipe with no foil over it or between it and the pipe to ensure a more accurate reading. ![]() #Heat tape for pipes install#It is recommended to install a foil material between the pipe and the heat cable to avoid direct contact and help provide a more even heating. Some applications may require heat cable to be applied to opposite sides of the pipe at a lower temperature to distribute the heat more evenly, avoiding one direct area of concentrates heat which may damage the pipe. The manufacture of the plastic pipe should be able to provide information as to the maximum temperature and how close heat cable can be spaced or wrapped on the pipe to avoid damage. This system increases the power to the cold spots and decreases it to the warmer areas, which provides a more even heat source. Self-regulating heat cables have a conductive core between two bus wires that becomes more conductive when cold. There is heat cable designed specifically for plastic pipes that is self-regulating and has limited wattage. ![]() An automatic heat trace control can monitor and maintain the system’s temperature, alarm for problems, and shut off the heat cable to prevent damage. It is always a good idea to use a heat trace system with an automatic thermostat and control, but especially so when using heat trace on plastic pipe.
