摘要

The system has heaters that are connected on smoke and heat outlet openings or light openings, where the heaters melt snow and ice surfaces. The heaters are arranged at dome and spaced by spacers preferably thermostable spacers, where the system encompasses an opening surface of the smoke, heat outlet and/or the openings. The spacers are glued on or screwed onto the domes, and are formed at a distance between the heaters and the domes. A control unit is connected over a snow sensor.
