The regular variation of the surface temperature field of floor in the types of floor radiation heating system was described. Because of the variability of the floor thickness and materials, it is difficult to control floor surface temperature. In the typical design, the floor surface temperature is always higher than standard temperature due to heat transfer to the ground ignored. On the basis of the heat transfer equation, a mathematical model of the floor temperature field in the floor radiant heating system was simulated. The finite-differenee method was taken. The computational results are in good agreement with the experiments. A precise method for engineering design is provided.
