A significant number of industrial and commercial piping systems require temperature maintenance. Both freeze protection and process temperature maintenance can indicate the need for heat tracing. Sometimes temperature maintenance can simply be accomplished by installing only thermal insulation. In other cases, however, temperature maintenance must be provided by the addition of heat in the form of electrical heaters, steam tubes, or hydronic fluids. This article will mainly focus on Electrical Heat Tracing, the choice of many of new installations in both industrial and commercial projects. In 1960, about 95% of heat tracing was steam and in 1995, because of improvements in electrical tracing, that number dropped to between 30% and 40% of new installed tracing.

Reliability Requirements

To make use of a visual symbol, electrical heat tracing is like a stool with 3 legs (see Figure 1). One leg is “heating cable quality” (heat trace cable and thermal insulation); the second leg is “engineering quality” (choosing the proper wattage, thermal insulation, ambient temperature, safety factors, etc.); and the final leg is “installation quality,” or the quality of the installation of the piping system and heat tracing system. If any one of the legs is compromised, the system may not provide expected performance. Break any one of the legs and the system will not “stand.”

An electric Self Regulating Heat Cable is a wire cable that produces heat, also referred to as heat trace cable. Heating cable can be used in a wide range of applications for the home, such as floor heating, heat loss replacement, pipe freeze protection, roof and gutter deicing, and snow melting. There are two different kinds of cables, self-regulating and constant wattage, and both can serve the same purpose, although the application will typically determine the best solution for the job.

Are heat tape, heat cable, and heat trace different?
