ABSTRACT:
A device for melting snow and ice from outdoor surfaces is disclosed in which a plurality of mats are provided. Each mat includes lengths of hose tubing in which flows a warmed mixture of water and antifreeze, which mixture is heated by a heating unit operatively connected with the mats through appropriate supply and return lines. The mats themselves are grouped into three classes: Driveway mats, walkway mats, and sidewalk mats, all of which may be arranged to adapt to many different outdoor surface configuration. Most of the mats are also provided with a set of three valves which are used to control the flow of mixture, so that mats down-line may either be supplied with the mixture or may be cut off from it, so that selected surface areas may be warmed to have the snow and ice thereon melted. Each mat is further comprised of an upper mat portion and a lower mat portion, where each portion is made up of three separate layers designed to conserve as much heat energy as practicable.
