The floor heating water distributor is composed of the main water distributor and the main water collector. The main water distributor is connected to the water supply pipe of the pipe network system. Its main function is to distribute the hot water from the water distributor of the pipe network system to the indoor rooms requiring floor heating through the floor heating pipe buried under the floor.
When hot water flows in the floor heating pipe, it transfers heat to the floor, and then radiates heat to the room through the floor. The other end of the floor heating pipe is connected with the water collecting main pipe of the water diversity collector, and the return water with lower temperature after indoor heat dissipation returns to the pipe network system through the water collecting main pipe to complete a cycle.

Diversity water collector is the "hydraulic hub" of floor heating system
Due to the influence of hydraulic characteristics, the length of heating pipe should be limited in a certain range. So the area that a loop can cover is limited. For this reason, the realization of heating in an area should be realized through multiple loops, and the device that distributes and collects heat medium for these loops is the water diversity collector, so people usually call the water diversity collector the "water conservancy hub" in the floor heating system.
