An electrical heating unit of the integral element type, comprising an electrical heating element indirectly bonded to a supporting lithium aluminosilicate glass-ceramic plate, is described. The glass-ceramic plate is provided with a semicrystalline zinc aluminosilicate coating which protects it from the harmful effects of interaction with subsequently applied ceramic and metallic compositions making up the heating element and associated components.
