The "Self-Regulating" in the name means that the cable will get warmer at 0º then at 30º. The ability to generate more heat only when needed means it will save energy over the "box store" cable that is always the hottest it can be.

Our cable can be used to prevent ice from forming in your gutters or to melt snow snow on your roof. The typical design is to keep the melted snow flowing to the gutter and then down the spout so ice dams will not form at the drip edge.
