    Abstract: The snow melting mat includes an elongate, substantially flat sheet of a desired length connected to a recirculation header at one end and a circulation header at the opposite end. The sheet includes a plurality of channels defined inside the sheet. The channels permit heated liquid to circulate along the length of the sheet. A heater-pump heats the liquid that maintains the temperature of the sheet at several degrees above freezing and pumps the liquid through the recirculation header, the sheet, and the circulation header. A plurality of transverse grooves is formed on the top of the sheet to provide a gripping, walking surface. The grooves taper in depth to permit melted snow and ice to run off the sides of the sheet. Couplers and joints permit multiple sheets to be joined together in any desired pattern.
