A mathematical model of the heat transfer process of a low-temperature floor heating system was established. Through numerical simulation, the temperature field in the flat plate was calculated using the finite element method; a dynamic simulation program was used to obtain the temperature of the different supply and return water and the distance between the rows of tubes. The parameters such as the maximum temperature of the surface of the floor, the actual temperature of the room, the heat flux, the warm-up period and other parameters clarified the comfort and energy saving characteristics of the system.
