oh i love these post's, sorry for hijacking op,
but ffs guys who have just joined in the last 20 odd days , then advising on a g/w 50/60ff and post things like sytem pressure etc etc, get a grip and look at your books.
to the op you say your pump is working!! is the hot water still hot???
does both the flow and return return feel the same temperature ?(even 2 or 3 M away fro your boiler)
are you sure your heating zone valve is opened?
this is a circultion issue and as EXPERIANCED guys have pointed out this is more than likely either pump spindle no longer connected to impeller or a zone valve not operating properly!!!
