[Reliable Freeze Protection] Designed with a PVC shell and energy-saving thermostat, this cable operates at temperatures as low as -40°F (-40°C), ensuring metal or plastic pipes remain freeze-proof and maintain continuous water flow even in extreme cold. Each pipe heating cable includes a 3-foot power cord, built-in thermostat, and 35 feet of aluminum foil fiberglass tape for easy installation.

[Durable & Waterproof] Made from nickel-chromium alloy heating wire with a corrosion-resistant, non-magnetic design, this IP67-rated cable offers waterproof, dustproof, and flame-retardant protection, withstanding temperatures up to 194℉ (90℃).

[Efficient and Safe] Features a double-conducting, double-heating design with high-performance XLPE insulation and a tinned copper wire grounding shield, providing excellent mechanical protection, energy efficiency, and enhanced user safety.

[Automatic Temperature Control] The built-in thermostat activates when temperatures drop below 37℉ and automatically shuts off above 50℉, preventing freezing while conserving energy by adjusting output based on ambient temperature.

HISD-F Constant Wattage Heating Cable The HISD-F Constant Wattage Heating Cable is a reliable freeze protection solution designed specifically for residential and light commercial water pipes. Operating at 7W/FT, this cable delivers a consistent heating output that ensures water flows smoothly in freezing temperatures. Constant Wattage Technology Unlike self-regulating cables, the HISD-F provides a steady, unchanging heat output along its entire length, regardless of ambient temperature. This ensures dependable freeze protection even in extremely cold weather conditions. Its constant performance makes it an economical and efficient choice for long-term use. Built-In Thermostat A pre-installed thermostat is located near the plug end of the cable. The thermostat automatically activates the heating cable when the pipe temperature falls to approximately 37°F (3°C) and switches it off around 50°F (10°C). This feature helps conserve energy, prevents unnecessary operation, and reduces electricity costs while extending the service life of the cable. Installation Requirements The cable must be installed in a straight run along the length of the pipe. It cannot be wrapped, coiled, overlapped, or crossed, as this could lead to overheating and damage. Pipes must be completely filled with water at all times during use, as running the cable on empty pipes can result in overheating or fire hazards. The cable should be firmly secured to the pipe with electrical tape or cable ties and covered with proper pipe insulation (such as fiberglass pipe wrap) for best results. Application Conditions The HISD-F cable is designed for use on metal or plastic water supply pipes in residential homes, basements, crawl spaces, garages, and other unheated areas. Should always be plugged into a ground-fault protected (GFCI) outlet for safety. Key Advantages Reliable 7W/FT constant wattage output for steady freeze protection. Built-in thermostat for automatic energy-saving operation. Easy installation with a pre-assembled plug-in design. Suitable for metal and plastic water pipes. Durable construction with long-lasting performance in cold climates. The HISD-F Constant Wattage Heating Cable is an efficient and dependable solution to keep your pipes from freezing during harsh winters, providing both safety and peace of mind.
