This modular snow melting carpet device for melting snow and ice on pathways comprises a flat sheet of generally rectangular shape, two conducting wires embedded in the sheet and running along the length of the sheet and generally close to their respective length edge. The conducting wires are connected at both of their extremities to a female single pin connector also embedded into the sheet and exposed at the width edges. The device also comprises a plurality of heating elements also embedded into the sheet and parallel connected along said conducting wires and, two male single pin connectors adapted to mate with the female connectors of one edge and connected to a power source. Additionally, an intersection device may comprise two crossover connecting wires embedded into the sheet and electrically insulated from the conducting wires and heating elements. Both extremities of each crossover wires are connected to an additional female single pin connector exposed at both length edges of the sheet and in close proximity to its respective width edge. Two of these additional connectors, close to a same width edge, are electrically connected to their respective closest connector. The crossover wires allow for interconnecting another device to any of the four edges of the modular device. All female connectors are maintained covered by removable insulating plugs that can be replaced by double male couplers to parallel connect two adjacent heating devices. All distances between each female connector and its respective closest sheet corner are equal to each other, in order to allow for electrical connection between two adjacent modular carpet devices.
