Abstract
An electrical heating system thin enough to be installed under finished flooring. A meshwork mat constructed in a leno configuration receives an electric heating element which is threaded through aligned openings in the twisted strands of the warp strands. The strands of the mat and the intersections between the criss-crossing warp and weft strands are coated with a polymeric fusing material. The heating element is arranged in side by side runs to minimize the electromagnetic field effects. Connecting runs between adjacent pairs of side by side runs are arranged linearly end to end. A return wire is extended adjacent to and side by side with the connecting runs.
