Floor Heating Cables

Floor heating cable systems have no mat that holds the wires in place and maintains ideal spacing; it is your job to build your own mat on the floor using the cable straps or guides and weaving the wire back and forth, clipping it into the tabs on the straps. Most of our PRO and DIY customers buy mats because of their time-saving and easy installation, but we offer cables too—it’s the “old way” and how electric radiant floor heating began. Once the cable is installed, you proceed installing your floor covering the same way as with mats.

Floor heating cables allow for flexible installation. You can vary the spacing on WarmWire cables, bringing them closer than the standard 3.0 inch spacing (same heat output as mats) to 2.5 inches for a 17% boost in heat output. When you space WarmWire closer together, you cover less Square Footage, so be sure to consult the spacing chart in each item’s specification. Ideally use the same spacing over the entire floor. Remember, SunTouch TapeMats also allow you to cut the mesh mat and free the heating wire for flexibility in covering curves and angles too.

Nuheat cable is very similar to WarmWire, though the spacing of the cable is slightly different. The standard cable spacing for Nuheat cables is also 3 inches, but this can be changed to an alternating 3-2-3-2 spacing if more heat is desired. This alternate spacing increases the heat output by 25%.

Floor Heating Cables can be the more economical option for installing floor heat in room. Just remember that while you save money on the materials, you will spend much more time on installation. It all depends on where you want to spend your time and money on your project.

Just as with Mats, choose the Cable size that will cover your open floor area and leave no cold spots, but will fit completely. DO NOT CUT OR SPLICE THE HEATING CABLES. This will cause them to heat improperly and may drastically lower the life expectancy of the system.
