Heating device for wall, ceiling or floor coverings
The invention relates to a heating device and in particular to an element of a floor heating device. Known floor heating devices comprise heating means which are arranged underneath floor coverings, for example, below stone plates, tiles, parquet elements or laminated panels. Those heating means can be made of electrically heatable films which are arranged close to the surface of a covering in order to directly heat the room.
1. An element for a wall, ceiling or floor covering including a heating means, and two different bushes which differ from each other by means of diameter or shape, or both, and which are electrically connected with different conductive sections of the heating means.
2. The element according to claim 1 , wherein the element is a floor panel, and the heating means are arranged in the upper third of the floor panel, as seen from an upper surface of the covering.
3. The element according to claim 1 , wherein the heating means are arranged between a carrying board and a decor layer.
4. The element according to claim 1 , wherein the heating means is formed of cords.
5. The element according to claim 1 , wherein the heating means are provided in the form of a network, meshwork or web.
6. The element according to claim 5 , wherein the meshwork is formed from heating cords which run parallel to each other and by electrically non-conductive cords which run perpendicular to the heating cords.
7. The element according to claim 1 , wherein the heating means comprise metallically coated cords.
8. The element according to claim 1 , wherein the heating means comprise glass fibers.
9. The element according to claim 8 , wherein the glass fibers are at least partially metallically coated.
10. The element according to claim 1 , wherein the element is a laminate or parquet panel, which is provided on a top side with a decor paper or a layer consisting of wood, adjacent to the heating means.
11. The element according to claim 1 , wherein the bushes lead out of an underside of the element.
12. A plurality of elements) according to claim 1 , each element having a rectangular surface with large and small sides, and the elements being connected electrically as well as mechanically at the small sides.
13. The plurality of element according to claim 12 , wherein the elements are connected electrically at the small sides by means of flat strip conductors having protruding contacts.
14. The element according to claim 1 , having multiple layer systems above a carrying board, wherein a top most layer system is impregnated with a resin.
15. The element according to claim 1 , wherein the element is a floor panel.
16. The element according to claim 1 , wherein the heating means comprise a NiCr-alloy.
17. Heating means for an element according to claim 1 , wherein the heating means is a network, meshwork or web, comprising heating cords running parallel to each other and electrically non-conductive cords running perpendicular to the heating cords, as well as electrically conductive sections, running parallel with the electrically non-conductive cords.
