NOVELTY - The invention claims a planar heat diffusion type electric floor heating system, relating to the technical field of domestic floor heating, comprising an insulating layer, an infrared heat energy reflecting layer and a heating cable, wherein the infrared heat energy reflecting layer is set above the insulating layer; the heating cable is connected with the power supply; the upper part of the infrared heat energy reflecting layer is provided with a plane heat diffusion layer; the plane heat diffusion layer is graphite or graphene coating heat conducting film; the heating cable is set above the plane heat diffusion layer; the heating cable is fixed with the insulating layer through the first nail; the first nail passes through the plane heat diffusion layer and the infrared heat energy reflecting layer; The zinc metal net set above the heating cable. the upper part of the heating cable is provided with zinc metal net which not only can shield the electric field, but also has the function of reinforcing rib net. The heating cable is a double-guide structure, which can counteract the magnetic field. using graphite or graphene coating heat conducting film as the diffusion layer; the heat is uniformly diffused to the four sides; the local temperature is too high; the user experience at any position; the temperature difference is small, and the comfort is high.
