A serpentine etched foil heater has a segmented serpentine conductor group made up of a plurality of spaced-apart elongated serpentine conductive strips that are connected in parallel and are everywhere aligned with each other. Advantageously, central conductive strips are wider than are conductive strips along the edges. Further advantageously, the conductive strips are bridged by conductive regions that extend along lines of constant voltage. This makes it possible to handle the heater element without causing it to become tangled. The heater is especially suitable for low voltage applications.
