I've been a plumber for quite a while, but have limited experience with boilers. Mostly I just pipe them up according to the design, so keep that in mind when I say this; I thought it was commonly accepted that "pumping away" (there's an article on this by the same name) from a boiler was the preferred way, as it kept turbulence inside the boiler and the various devices, (low water limit, etc) located near the boiler, to a minimum.
You and I seem to be in the same boat, and yes your pumping away logic makes sense to me
She never made it past the bedroom door, what was she aiming for...? She's gone shootin..
