Watts Radiant WarmWire Electric Floor Heating Cables, 120VAC

WarmWire® is a simple, economical way to warm floors and provide years of lasting comfort. Warm all kinds of floor coverings: ceramic tile, stone, wood, laminates, vinyl or carpet.

There's a WarmWire spool sized for your project. Lay out and attach the WarmWire strap. Fasten the WarmWire to the strap as you weave it back and forth across the floor. Put down a layer of thin-set mortar and set your tile or stone, or install a layer of self-leveling cement over the cables for hardwood, laminate, vinyl or carpeted floors. Our installation manual will show all the details.
