This 240 volt WarmWire(R) cable is designed for installation in interior floor areas and to provide heat to warm the floors and help keep bathrooms, kitchens, and entryway floors dry and safe. The cable system consists of an electric heating wire that is built with a tough, water-proof jacket and will cover 60 square feet when installed with 3 inch spacing. It is secured to the subfloor with HeatMatrix(TM) uncoupling membrane mat, CableStraps(TM) or hot glue, and then covered with thin-set or self-leveling mortar. Once the mortar has cured, connect the system to 240 volt AC power. The temperature of the floor is controlled with a SunStat programmable or non-programmable thermostat. An in-depth installation manual is included.
