Hydronic heating system piping diagrams. In this design which can also be used in residential systems each heat emitter is located within a separate branch circuit that connects to a common supply main and common return main. Designing high performance hydronic heating systems involves a knowledge of fluid mechanics electricity heat transfer and control theory. Terminal units fan coils chilled beams finned tube radiant etc. This system connects the boilers to a header system that leads to a hydraulic separator.

Designing high performance hydronic heating systems requires a good understanding of fluid mechanics electricity heat transfer and control theory not to mention a myriad of architectural issues. Still in my opinion there are better options that provide the benefits of primary secondary piping but with simpler and less expensive piping configurations as shown in figure 3.
