Abstract
The invention relates to an air heating device with a hot air fan located in a housing to deliver hot air from an air inlet opening which is located on the face side via a heat exchanger to a hot air exit opening located on the opposite face. The object of the invention is to devise an air heating device which can always intake a sufficient amount of hot air regardless of its installation position without additional parts. This object is achieved by the fact that the housing near the face air inlet opening on its outside periphery on at least one side has additional air inlet openings.
