AI summary

Infrared wall panel heating comprising flexible heating fabric, in which a glass filament fabric is provided as a heating fabric, into which are woven carbon filaments, as heating elements, and metal electrical conductors, said metal electrical conductors being positioned transversely to the carbon filaments at both ends of the heating element and tightly enclosing the carbon filaments, and said heating element being electrically protected on each side by a layer of insulation film. The wall panel heating is characterised in that at least two additional layers of insulation film and an additional layer of non-woven and woven fabric are provided on each side to protect the heating element, in particular mechanically. The heating can therefore be installed, in particular under plaster, on a wall with a direct connection to the local electrical grid.
