Panel heater for use in inner surface for heating e.g. part of building, has reflective layer for reflecting electromagnetic beams and arranged on layer or separation layer on layer that comprises construction material and particles

摘要

The heater has a layer comprising a binding construction material and electrical conducting particles, and exhibiting a thickness of 2 mm. A side of the layer is applied as a back part of a building part, where regions of the layer are connected with electric conductors and designed as electrical heating resistors. A reflective layer for reflecting electromagnetic beams is arranged on the layer or a separation layer on the layer. The material comprises electrical conductive polymers. The particles comprise carbon, metal, electrical conducting plastic or carbon fabric layer particles. The reflective layer consists of a metal or a metal oxide, and is designed as a monochromatic or polychromatic film. The binding construction material is designed as an inorganic binding construction material, a bound water contained binding building material, a polymer having conjugated double bonds and molecular complexes or a pyrolyzed product contained binding construction material. The electric conductors are designed as flexible circuit boards.
