>> what ultimately happen if I couldnt get this valve turned off?

Your mains water pressure will be no more than 10 bar, and probably substantially less. All the pipe joints on your heating *should* be able to handle the equivalent of mains pressure, as they're the same type of joints as the ones leading to your taps etc. The boiler would have a pressure release valve though, as others have said. To then reduce the system pressure without disconnecting the filling loop you'd just open the drain cock at the lowest part of the system; although the concentration of inhibitor would indeed be reduced.
