Abstract
The present invention relates to a heating device for heating air and to radiator subassemblies and positioning frames and further relates to a method for mounting a heating device according to the invention. The positioning frames comprise means for snap-fittingly anchoring radiator elements and electrode sheets, thereby permitting an easy joining to obtain radiator subassemblies which can subsequently be arranged in layers or stacked in an easy manner. A heating device is thereby created with improved assembling properties. PTC elements are used as the heating elements.
