FLOOR HEATING SYSTEM WITH A SELF-CONTROLLING CABLE

摘要

The invention relates to a floor heating device comprising an electric heating cable (5) extending backwards and forwards underneath the floor surface (9) to be heated. Metal panels (1, 1a, 1b, 1c, 1d) of rectangular or square configuration are provided with channels (3, 3a, 3b, 3c) extending in parallel in the direction of deposition of the panels. Each metal panel (1, 1a, 1b, 1c, 1d) is fitted on its reverse side with an insulating panel (2) in a sandwich construction in such a manner that the channels (3, 3a, 3b, 3c) of the metal panel (1, 1a, 1b, 1c, 1d) penetrate into the material of the insulating panel (2). The assembled panels (1, 1a, 1b, 1c, 1d) and panels (2) are deposited on the support (4) of the floor in juxtaposed relationship in the longitudinal and transverse directions in such a manner that each channel (3, 3a, 3b, 3c) of one metal panel (1, 1b, 1c, 1d) continues into another channel (3b, 3c, 3a, respectively) formed in the adjacent metal panels (1b, 1c, and 1a, respectively) at the end edge sides of the first metal panel. The heating cable (5) is arranged inside said channels (3, 3a, 3b, 3c) so as to extend from one metal panel (1a) to the next backwards and forwards across the floor.
