A heating body for an electrically heated filter screen includes a heater element having an outer surface and a metallic protective layer having an inner surface. An insulating layer is disposed between the heater element outer surface and the inner surface of the metallic layer. The metallic layer and an exposed portion of the insulating layer define an exterior of the heating body. An electrically heated filter screen constructed from pairs of intersecting heating bodies is also described.
