Abstract
An electric heating unit for attachment to a rear surface of a mirror to reduce the formation of condensation on the mirror surface including a moisture resistant low heat conductivity heat barrier formed of a layer of closed cell plastic foam, a length of insulated low resistance heater wire mounted on the surface of the foam layer and connected to a voltage source, an aluminum foil covering the heater wire and the surface of the foam layer and adhesively connected thereto, an adhesive layer covering the outer surface of the aluminum foil, and a peel-off backing covering the adhesive layer to permit attachment of the heater unit to a mirror when the backing is removed. The components of the unit are selected to produce less than 120 watts per square meter of heat to a mirror to which the unit is attached.
