The existing floor heating mainly comprises an electric heating floor heating system and a water heating floor heating system. Wherein, the construction mode of water floor heating does: the water pipe is laid on the ground, then the concrete is cast in place and buried, and then the floor tiles or the floor are laid on the surface. When the water heater is used, only hot water needs to flow in the water pipe, and the temperature of the ground can be increased. However, the water-heating floor heating system has the defects that the time required for heating the floor heating system to the use temperature is very long when the floor heating system is used firstly; secondly, once the water pipe has problems, the maintenance cost is high, the maintenance process is complex, and the maintenance time is long.

The heat storage slow release layer is arranged in the ground heating floor, then the ground heating floor is normally heated in a valley power state, meanwhile, the heat storage slow release layer stores heat, heat can be conducted with the floor after the heat storage reaches an upper limit, heating is stopped after the ground heating floor is heated to a required temperature in a peak power state, then when the temperature of the ground heating floor gradually drops to the release temperature of the heat storage slow release layer, the heat storage slow release layer slowly releases heat, the temperature of the ground heating floor is maintained, the electric heating time in the peak power state is further shortened, and therefore the use cost is reduced.
However, in the existing floor heating floor capable of slowly releasing heat, the heat storage slow release layer releases heat at the same time, so that once the temperature of the floor is reduced to the release temperature of the heat storage slow release layer, the heat storage slow release layer releases heat at the same time, the temperature of the floor is increased rapidly, and then the time for releasing heat is only one heat release period, so that the time for reducing electric heating in a peak power state is relatively limited, and the effect of reducing the use cost is poor.
