Help my Phaeton burns!!!

Hello everyone, every year in winter the sweat pearls are on my forehead. At the traffic lights massive smoke fumes always rise in front of the left headlight. Each time I am afraid that my Phaeton is about to burn down. But it is always the heater. Hopefully. Why can’t you just move the exhaust air channel to the rear? Would spare me some fear. Has also been addressed at a traffic light that my car is burning because the smoke got up from the engine compartment. Gruss capdoc
