NOVELTY - The utility model claims a closed graphene floor heating structure, comprising a bottom insulating layer, the middle layer and the floor decorative layer of heating cable; the heating cable layer is provided with live wire and zero line, live wire and zero line in parallel between the cable of the plurality of graphene, graphene graphene sleeve of cable is composed of a carbon fibre wire and an external inner part is composed of two ends of carbon fibre lines on the graphene wire is inclined to a connection live wire and zero line; the heating cable layer is graphene super-bag. The utility model has super heat effect, greatly reduces the energy consumption, and saves the number of the heating cable, reduces the cost and is safe and reliable.
