A glass pane including at least a glass sheet provided with heating strips powered by collectors, the heating strips being divided in groups. The power supply of the different groups is provided sequentially, each group being powered once per sequence. The supply is provided by a device equipped to measure the outside temperature and the temperature of the outer surface of the glass, to determine a minimum heating time for each group according to the outside temperature, and to maintain the heating in the group as long as the outer surface temperature of the glass opposite the group is not higher than the melting point of ice. |
