Abstract: In an electric radiator having a frame in which an arranged heat output elements, which include PTC resistors, and heating elements including fins, which abut on these heat output elements. The heating elements are supported by two oppositely disposed frame bars in such a way that they apply pressure to the heat output elements, said frame bars including rails having a U-shaped cross-section with flat legs extending from a central leg which is provided with longitudinally extending bulging portions separated from the central leg to impart spring properties to said bulging portions which is applied to the heating elements.
