IME your average 2/3/4 bed house will have a pair of 22mm pipes that
meander through the house sprouting 15mm offshoots to each radiator.
Some of the offshoots might feed more than one radiator (eg in our
current bathroom the 15mm "spur" that feeds the towel radiator
also
drops down to the cloakroom and lounge skirting radiators below).

You're unlikely to find anything as sensible as a manifold unless you
specified it when the heating was installed!

All the radiators should be in parallel though, of a fashion.
