I'm not expert. I'm not sure of the word that would describe my PEX
manifold (not looking at my *.PDF). There is a loop H/C at the top. I
wish I knew the exact wording, but I know cold water is looped back to
the heater, when hot is demanded.

If you can find a reference for this I'd appreciate it.

Gosh that "word" escapes me now.

I believe that's a convection circulating system.

Large buildings use a circulating pump in the hot water piping, with
a large central boiler as the source.

Did you hear about the new saint, San Adreas? He's the patron saint of
blame, it's all his fault.
