That's a demographic that would especially benefit from a warm floor. According to Rapp, most of his company's installations of electric radiant tile systems involve more than 200 square feet. It takes two packages, one with the cable and attachment system, the other with the control thermostat and other accessories for installation. The process can differ depending on new or retrofit construction. In new construction, the electrical box and circuit can be installed preparatory to installing the flooring.
Cable is laid out and woven in serpentine fashion and fastened to the substrate.
At that point, a segment of non-heating conductor, typically 10 feet long, is fished up through the wall to the box and connected to the thermostat, which will control the heat level in the tile. The cables for radiant floor systems are sold in different sized kits and patterned appropriately according to the attachment system. Typically, at the center, cable has a resistance heating wire which is insulated with a cross-linked polyethylene thermal plastic which is covered with a nylon jacket. A copper braid grounding conductor is then applied and finally a nylon jacket covers the conductor. There are some elements that are required by code, but often, there is a choice in achieving those standards.
