Hybrid printed heater with selectable ptc effect

A method of manufacturing an electrical heating device (10), in particular for automotive applications, comprises the steps of: (42) cutting a sheet (14) of highly conductive material through a suitable thickness to obtain a predetermined line pattern (16) comprising at least one electrically conductive line (18, 20, 22) wherein an electrically conductive bridge member (24, 26) interconnects portions of the at least one electrically conductive line (18, 20, 22), (46) depositing a layer of curable adhesive material (28) onto the surface of the dielectric planar flexible carrier (12), (48) placing the obtained line pattern (16) onto the layer of adhesive material (28), (50) curing the adhesive material (28) below the line pattern (16) in addition to the adhesive material (28) below the bridge members (24, 26), and (50) applying the cured adhesive material (28) to the dielectric planar flexible carrier (12). (52): cutting through each bridge member (24, 26) at all ends between portions of the at least one electr
