1. A heating apparatus for the conductive heating of a melt, comprising:
at least one electrode; and
a first cooling system configured to transport a cooling fluid to cool the at least one electrode, the first cooling system having means for controlling a cooling power variably as a function of time and location in a plurality of selectable regions of the at least one electrode.
