  • FIG. 2 shows a special configuration of the heating device 1, which allows different temperature zones to be generated. This is done on the one hand via the different amounts of air that leave the air outlets 32 of the air outlet 31. On the other hand, this is done here via outlet 51, which emits the air that has already given off thermal energy and is therefore cooler.
