However, when using these structures, it is difficult to design a modular system of heaters, which is often necessary for uniform and efficient heating of rooms.

Also known is the “Electric heating panel” [RU patent for the invention No. 20144760], comprising a housing in which a flat resistive element is mounted, located between the heat sinks and separated from the latter by electrical insulation. The heat sinks are made of a flat heat-conducting material rolled up into a roll, with the formation of a multilayer continuous resistive element together with the heating element. The heating element is made of known resistive materials, for example, nichrome, fechral.
