Basement, pipe trench, inspection well. One per unit or per building.

(1) hot water heating and outdoor pipe network directly connected to the system, should be set in the supply and return water mains flow adjustment valve, drain, thermometer, pressure gauge, if necessary, should be equipped with a heat meter and decontaminator.

(2) When the water supply temperature of the heat network is higher than the water supply temperature of the heating system, a water mixer or heat exchanger shall be set up as necessary.

(3) steam heating system, depending on the circumstances of the pressure reducing device or two shut-off valves to reduce pressure.

(4) When there are 2 or more loops at the inlet, a splitter cylinder or water distributor can be provided as needed.

Expanded information:

Hot water heating system heat inlet: the role of the circulating pipe is when the outdoor heating system installation is completed, flushing, pressure testing and test run, in order to avoid sediment dirt into the indoor heating system, should be closed into the indoor system of supply and return water valves. Open the valve on the circulation pipe for outdoor system circulation, test the external network operation is normal.

Control valves can also be used for indoor system for maintenance, does not affect the heating of other buildings, close the supply and return valves can be. Pressure regulator is generally used for large-scale high-temperature and high-pressure hot water heating system. Pressure regulator can be depressurized to adapt to the requirements of the indoor heating system circulating water volume and pressure.
