A driveway heating system for maintaining outdoor paved surfaces free of snow and ice comprising a plurality of electric heating devices placed along the outdoor paved surfaces adapted to melt snow and ice therefrom in the event of a snow storm. The heating device includes a housing defined in part by exterior panels, wherein the exterior panels facing toward the pavement structure are constructed of high thermal conducting material, and the exterior panels facing away from the pavement structure are constructed of thermal insulating material designed to maximize heat transfer to the pavement structure. The housing of the heating device serves to contain an electrically powered heat source. When the heating device is activated, the heat released from the heat source raises the temperature of the exterior panels with high thermal conductivity to transfer the heat to the surrounding pavement structures, whereupon the heat radiates outwardly to melt snow and ice from anticipated sections of the paved surfaces.
