Stay warm indoors during winter time. Dr Heater self-regulating heat cable will de-ice your roof every winter effectively and energy efficiently. No more dangerous icicles hanging off the roof, no more damaged gutters and downspouts by ice, and no more heavy snow piled up on the roof. Radiant roof and gutter heating and de-icing systems are recognized as extremely effective in preventing the problem caused by heavy snow and ice that can form on the roofs of buildings. Dr Heater's self-regulating heat cable is suitable for roofs, gutters, and drain pipes and is capable of keeping your home or business safe from costly ice and water damage, frost erosion and dangerous falling ice. Dr Heater's self-regulating roof and drain pipe heat cable is composed of rugged durable outer construction (Thermoplastic elastomer) to withstand winter's harsh conditions. The self-regulating cable also features an irradiated conductive core that increases the heat output as the outside temperature falls and decreases the heat output as the temperature rises. This unique construction makes it durable, safe, and extremely energy efficient. The cable is ETL certified for the USA and Canada.
