What is the difference between Outpipe and GutterMelt?

Outpipe and GutterMelt share the same fundamental cable construction and the same three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. The difference is application. GutterMelt is designed for gutters, downspouts, and roof eaves. Outpipe is designed for pipes, valves, and tanks. Both are ETL listed for US and Canada, carry a 10-year warranty on bulk and MI cable and a 5-year warranty on pre-configured kits, and use the same self-regulating technology that prevents overheating on temperature-sensitive materials.
