Basic Installation of the In-slab Floor Heating Cable

 
Warmup In-slab Heating Cable is designed to be placed within the cement slab of at least 2” (50mm) in thickness, with at least 11/8” (30mm) of slab above the heating wire.

For thicker pour of up to 6”, elevate the wire mesh with bricks, wood blocks or other spacers to float the cable at the desired level. Depending on the construction of the subfloor and in general, in order to improve the efficiency of the system, you may need to apply insulation prior to the pour.

In most common instances, zip-tie the cable to a 16 Ga wire-mesh (“re-mesh” type) or similar with 4”x4” square openings. Elevate the mesh as needed and leveled to the desire depth in relation to the size of the pour. Warmup recommends keeping the cable about 2” from the surface. When applying the cable to an existing slab or substrate using metal fixing strips, lay the cables out perpendicular to the cable runs. Secure the fixing strips with screws, hot-glue/ liquid nails or any suitable adhesive to avoid movement when looping and stretching the cables. Lay additional runs of strips where needed to avoid spans over 4 feet.

REMEMBER TO TEST THE RESISTANCE OF THE CABLE BEFORE, DURING AND AFTER INSTALLATION.
