Heated Floor Wire

TrulyWarm Electric Heated Floor Wire

TrulyWarm heated floor wire is the core of any electric radiant floor heating system. This flexible, durable heating cable installs in the thin-set mortar layer directly beneath your tile or stone flooring, delivering even, consistent warmth across the entire floor surface. It is the same type of resistance heating cable used in premium systems like Schluter Ditra-Heat—at over 60% savings.

Our heat wire is available in a wide range of lengths to cover bathrooms, kitchens, mudrooms, basements, and other hard-surface floors from 20 square feet up to 300+ square feet. Each spool includes a factory-terminated cold lead for easy connection to a thermostat, and the cable is rated for use under tile, stone, marble, and other thin-set-applied flooring materials.

TrulyWarm wire can be installed loose over a Prova Flex uncoupling membrane using cable clips, or secured with adhesive cable straps directly on the subfloor. Either method produces professional, reliable results.

• Flexible heating cable in multiple lengths for any room size
• 12 watts per square foot for fast, efficient heating
• Factory-terminated cold lead—no field splicing required
