The RAYPAK H611100 is a Raychem Wintergard heat cable designed to prevent pipe freeze-up in residential and light commercial applications. Heat cables of this type apply controlled, low-wattage heat along water supply lines, drain lines, and other vulnerable piping runs exposed to freezing temperatures. The H611100 is installed by licensed plumbers, mechanical contractors, and experienced pipe insulation specialists who need reliable freeze protection in areas where ambient temperatures drop below 32 degrees F. Its self-regulating or constant-wattage design maintains pipe integrity through cold-weather seasons.
Wintergard heat cable is commonly used on residential water service lines, outdoor spigot runs, rooftop drain lines, and exposed piping in unconditioned crawl spaces, attics, and garages. It is well suited to both new construction freeze-protection rough-ins and retrofit installations on existing plumbing. Where local codes require pipe insulation over heat cable, standard foam or fiberglass pipe wrap is applied over the cable after installation.
Designed as an OEM-style replacement or direct-fit heat cable for freeze-protection applications on residential and light commercial water supply and drain piping systems.
Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes and the National Electrical Code (NEC) for low-voltage heating cable circuits. Power to any existing heat cable circuit must be de-energized at the breaker before removal or replacement. The cable should never be overlapped on itself, as this can create hot spots and damage the cable jacket. After installation, pipe insulation should be applied over the cable to maximize efficiency.
