Safety valve is inside heating station right behind heat exchanger as shown on pic.

Yes at given moment. See below pic of how it is done. So 6.5 bar Of course, there is a couple km of pipe network. What would be the pressure before the pump and after the pump? It has to be less than safety valve release pressure and high enough to circulate water through whole network.

It is real application and the pump is running right now. Flow is 71 m3/h, pressure in supply pipe is 8.5bar and in return pipe 4bar.

OK, but are my assumptions for pressure occurring in system correct?

I don't understand air-caves. It is closed system without any air inside.

Hello, I need help with defining pressure in closed district heating system. As shown in attached drawing, we have a heating station which supplies hot water (110/70 degrees C) to various households. The lowest house is 90m below station and the highest one is 20m above. I need to determine...
