Primary Tee Direction with Low Loss Header Secondary
Hello, I’m a long time lurker!
Question on Tee direction for primary secondary plumbing.
I would like to emulate this layout (borrowed from caleffi) however I’d like to confirm it is correct. I will be using only one boiler and would like two headers coming off the primary loop. In every other example it seems like primary loops always go through the “run” of the tees and the secondary is flows from the “bull” of the closely spaced tees. The diagram shows the opposite. Does the low loss header have to go through the run to decrease turbulence?
