NOVELTY - The utility model relates to the technical field of building decoration, especially relates to a ground system with constant temperature, comprising a floor heating plate, a reflecting insulating layer, an extruded heat insulating layer, a first moisture-proof layer, a cement levelling layer, a reflecting insulating layer, an extruded heat-insulating layer, a first moisture-proof layer, the cement levelling layer is orderly and fixedly set from up to down, the floor heating plate is fixed above the reflecting insulating layer, the floor heating plate comprises a side wall and a bottom plate, the side wall is integrally formed around the bottom plate, the side wall and the bottom plate form a containing space, the containing space is provided with a water heating pipe and a plurality of graphene heating layer. Compared with the existing technology, a ground system with constant temperature of the utility model can effectively keep the temperature of the ground system maintained relatively constant by the double heat preservation effect of the water heating pipe and the graphene heating layer, reaching the purpose of delaying heat dissipation, which is good for maintaining the indoor temperature constant, reducing the air conditioner device power consumption and improving the heat preservation performance.
