All Heat-Line products feature self-regulating heating cable (conductive polymer) technology which has the ability to increase heat output with cold but more importantly, decrease heat output with warmth. With this unique technology, every Heat-Line system is designed to prevent over-heating of pipes while maintaining them from freezing efficiently. The main benefit of self-regulating technology is it allows the use of thermal pipe insulation for the first time. Prior to Heat-Line and self-regulating heating cable technology, heat traced water pipe would NEVER have been insulated as they would overheat, melt and intensify the risk of fire. As these pipes were not insulated, a huge amount of heat energy (wattage) was required to heat the pipe to prevent freezing.

A pipe protected with thermal insulation and a Heat-Line system needs only a tiny fraction of the heat energy once required. Add a thermostat and the energy required is further reduced to the lowest possible standard. Even in the coldest environments, a Heat-Line system combined with insulation and a thermostat will provide the most reliable and energy efficient system available on the market today.

Heat-Line has been the leader in the freeze-protection industry since 1988. This is due to the unique heating cable technology, reliable products, superior customer service and expertise in the field.
