Abstract: Electric Room Heater in its housing contains heaters which consist of strip of oriented cold rolled transformer sheet that are cooled by natural air circulation. Heater consists of two cross supports (11) connected by a central support (14). Between the cross supports are placed non-flammable insulating holders (13). The insulating holders have sprockets. Between sprockets lies strip of the heater of oriented cold rolled transformer sheet (12). The insulating holder (13) by its width (17) creates distance between layers of heater strips, and by sprockets width (18) makes distance between adjacent strips, windings, in the layer. These distances make channels for air circulation, thus enabling strip temperature to be less then 100° C.
