Abstract	This paper presents numerical simulation for heat transfer of radiant floor heating system, whose heat source is air-source heat pump. According to the results of simulation for heat transfer of different tube spacing in floor layer, it can be found that with the tube spacing increases, the average floor surface temperature decreases and temperature fluctuations enlarge. The recommended tube spacing is 100mm and 150mm. Practical experiments show that simulation results are reliable. Numerical simulation on tube spacing of 100mm and 150mm showed, for the condition of tube spacing of 150mm, the average floor surface temperature is low, and temperature distribution is uneven. While the heat flux for tube spacing of 100mm is 41.35 $W/m^{2},$ which is less than 47.3 $W/m^{2}$ of the tube spacing of 150mm, the reason is that tube spacing is smaller, heat transfer driving force for working fluid is smaller.
