Floor radiant heating is an advanced heating method Its working principle is to introduce circulating hot water or directly lay heating cables into the heating pipe loop under the laid floor or floor tiles, thereby heating the floor. The heat passes through a large area of the ground and is mainly radiated to the space above the floor in a gentle and uniform manner, making the human body feel the dual heat effect of heat and air temperature. The underfloor heating system is generally divided into three parts:

1、 Heating system (large boilers for centralized heating, wall mounted boilers, gas boilers, electronic infrared equipment, etc.)

2、 Control system (water collector, multifunctional filter, return water check valve, mixing pump, circulating pump, etc.)

3、 Heat exchange system (including insulation board, radiation paper, and fixed steel mesh, etc.).

The underfloor heating water separator is the control center of the entire indoor geothermal heating system. It has the function of diverting and dividing pressure. When the heat medium flows into the room, it enters the main bar of the water separator after passing through a multifunctional filter. In this process, the filter filters out impurities in the heat medium to prevent them from entering the underground pipeline network and blocking the pipeline. The main bar is installed horizontally, utilizing the principle of equal pressure at the same height to evenly distribute the heat medium to the branch pipes. After passing through the heat exchange system, each branch pipe flows back to the main bar and then enters the heating system through the return water outlet. In addition, a water mixing device is added to the self heating system, which means that after heat exchange, the temperature of the heat medium (water) is still high. After passing through the water mixing system, it flows into the main bar of the water separator for further circulation, which can save energy while heating.
