The request
“Draw a boiler-room P&ID with a condensing boiler, hydraulic separator, boiler and radiant-loop pumps, mixing and flow-control valves, radiant heat exchanger and expansion tank.”
Then tryAdd a second radiant heating zone.Change the radiant flow-control valve to fail closed.
What is in this drawing
Read the decisions behind it.
01
Modeled the hydraulic separator as a horizontal vessel (SEP-1) to separate primary boiler loop from secondary radiant loop.
02
Used a shell-and-tube heat exchanger (HX-201) to represent the radiant floor load.
03
Added temperature and flow control loops with field transmitters and shared controllers.
Use for hydronic boiler room P&IDs where a primary/secondary loop and radiant floor distribution need to be shown.
