Plate-like heating panel with electric resistors placed and glued in channels, method for placing the resistors and roller arrangement for carrying out that method

摘要

The flat heating radiator for buildings has a natural stone slab (1) with channels in its rear face to receive glued on heating pipes having serpentine or spiral sections to allow for heat expansion. The channels can extend for at least part of their length at an angle (alpha) to a perpendicular from the face of the slab. For successive pipe channels section (2a-2c), a serpentine or spiral a resulting channel length is formed, which in the area of the channel openings (Ka) is greatest and in the area of the channel base is smallest.
