What is the name of the place where the floor heating water supply and return water is located?

Water diverters and water collectors. The upper one is the water distributor, which is the water inlet; the lower one is the water collector, which is the return water. The floor heating water distributor is the control center of the entire indoor floor heating. It has the function of dividing flow and pressure. When the heat medium flows into the room, it enters the main bar of the water distributor after passing through the multi-functional filter. In this process, the filter filters out the heat. Impurities in the media are removed to prevent impurities from entering the underground pipe network and clogging the pipes.
