A heating system providing a heated surface for use on or in a driveway, roadway, walkway, patio, deck, stairs or the like, principally for outdoor use but usable as well for indoor use. The heating system includes a form suitably retained on an existing surface, at least one block disposed within the form, the block being molded principally of recycled rubber, thereby providing a frictional surface to prevent or minimize slipping. The heating system also includes heating elements for heating the block, thereby providing substantially improved moisture absorption and evaporation along with substantially improved melting capacity for ice or snow, and the block being removably disposed in the form for substantially easier and convenient repair, thus avoiding the necessity for digging up any concrete, asphalt or other materials.

1. In combination, a heated driveway, walkway, patio, deck, or stairs principally for outdoor use but usable as well for indoor use, the combination comprising a pan anchored to an existing surface, at least one insulating block disposed within the pan, the block being molded principally of recycled rubber, thereby providing a frictional surface to prevent or minimize slipping, and electrical heating means disposed between the block and the pan, thereby providing substantially improved moisture absorption and evaporation along with substantially improved melting capacity for ice or snow, and the block being removably disposed in the pan, whereby the block can be lifted out of the pan for substantially easier and convenient access to the electrical heating means, thereby avoiding the necessity for digging up any concrete or masonry materials.2. The combination of claim 1, further comprising keying means between the at least one block and the pan, thereby retaining the at least one block laterally in the pan.3. The combination of claim 1, wherein the electrical heating means comprises a conductive mesh.4. The combination of claim 1, wherein the electrical heating means comprises conductive wires.5. The combination of claim 1, wherein the at least one block comprises a plurality of blocks arranged in a pattern.6. The combination of claim 5, further including means for detecting and locating any fault in the electrical heating means, so that a block or a few blocks can be lifted up to provide access to the fault in the electrical heating means for a relatively quick and convenient repair thereto.7. The combination of claim 1, wherein the block comprises a molded sheet.8. The combination of claim 1, further including a plurality of blocks arranged in a pattern.9. A non-slip heated driveway, walkway or patio, comprising a pan anchored to an existing driveway, walkway or patio, a heating means laid in the pan, at least one block laid in the pan over the heating means and separate therefrom, such that the heating means is sandwiched between the block and the pan and is not physically connected to the block or pan, keying means between the pan and the block, thereby retaining the block against substantial lateral movement of the block within the pan, the block having an upper non-slip surface for pedestrian safety, yet accommodating vehicular travel thereon, and the heating means melting snow or ice accumulating on the block, whereby in the event of a failure of the heating means, the block can be simply lifted up and out of the pan the keying means, thereby providing convenient and ready access to the heating means for repair or replacement thereof.
