Abstract

The invention describes a heating apparatus comprising at least one heater (9) in which one or more electric heating elements (11) are arranged, and at least one heat transmitter (1), which is connected with the at least one heater (9), comprises heat transmitter surfaces and is formed from an extruded profile (1a, 28, 28a) in which the at least one heater (9) is fitted,in which at least part of the walls (6, 22, 22a) of the extruded profile (1a), which are not in contact with a heating element (11), is provided with openings through which a gaseous or liquid medium can flow through the extruded profile (1a, 28, 28a) in transverse direction to the direction of extrusion (17).
