NOVELTY - The utility model claims a ground heating pipe for heating system, comprising an inner pipe and an outer pipe; a graphene heat conducting layer is set between the inner pipe and the outer pipe; a heat insulating sheet layer; the graphene heat conducting layer is a poor arc structure; the heat insulating sheet layer is an excellent arc structure; the graphene heat conducting layer is located above the inner pipe and the heat insulating sheet layer is located below the inner pipe; two end surfaces of the heat insulating sheet layer connected with the graphene heat conducting layer are provided with extending heat insulating sheets extending outwards from the outer edge of the outer pipe; one side of the outer edge of the outer pipe is provided with a connecting bump and the other side is provided with a connecting groove; the water inlet end of the floor heating pipe composed of the inner pipe and the outer pipe is provided with a water inlet filtering component. The outer edge of the outer pipe of the utility model is provided with a connecting bump and a connecting groove; the adjacent pipes can be butted together conveniently when installed; it also can avoid the phenomenon of malposition; the heat insulating sheet layer can avoid the heat radiating downwards; the graphene heat conducting layer can better lead the heat upwards; It has better heating effect.
