The invention relates to the area of air heaters with flat heating elements. Electric heater has body as plate made of marble or ceramics. At the back side earthed metal base is attached to it by means of thermo-stable silicon layer, to this one in same way heating element is attached. In the center of the last one there is transverse gap in resistive layer. In that gap switch terminals are installed, those are placed in switchbox. Each terminal is connected to thermo-switch. The plate made of marble or ceramics is arranged of shaped sections attached to each other and to the metal base. This invention promotes increase of heat emission, thermal stability and safety of heater.
