WarmlyYours TempZone Floor Heating Cable (Twin) - Manual (Page 4)

1.1 Product Specifications and Details
Radiant floor heating systems are uniquely designed for use as primary or supplemental heat sources in residential or light
commercial applications for use under tile, stone, hardwood, engineered hardwood, carpet (approved for U.S. use only),
and laminate flooring.
The TempZone™ Floor Heating Cable (Twin) is composed of a twin-conductor cable and a cold lead of 15 feet for connection
to a power source. The heating cable delivers 3 watts/linear foot. Wattage per square foot depends on the installation. Refer
to the “Product Selection Guide--120V” or “Product Selection Guide--240V” in section 9 for additional information.
The TempZone™ heating cable consists of a copper alloy resistance-heating element insulated with a fluoropolymer
having high dielectric strength and the ability to withstand high temperatures to ensure safety. The core is surrounded by a
copper metal screening, which provides additional mechanical strength and a ground path. An outer fluoropolymer jacket
strengthens the cable and protects against corrosion.
