This paper first introduced the electrical floor radiant heating technology,and then created the indoor temperature model based on energy conservation,thus the causal relationship model between the indoor temperature and the required heating energy is obtained,the model parameters are estimated through the least square method. By analyzing the relationship between the energy storage and the heating process,we introduce the peaking loading shifting theory into the selection of energy storage time period. Simulation results show that the proposed intelligent system can correct the power of the heating cable and effectively realize the energy storage process.
