Hi Dave,
Thanks for your help , it appears the vessel was plugged with black gunge , flexi was ok , cleaned it all out , kickspace unit fitted all working ok now.Thanks for your help and info much appreciated.

Thanks Dave, i will check after chrimbo , need to drain system to do it , gert does not want me to meddle with it till then , i am going to add a plinth heater to system while i am at it will let you kmow what i find , by the way it does have a flexi hose to the vessel but the rear connection is at the back of the boiler, looks a bit of an arse to get at!!!

drain off a radiator at bleed valve and pressure should drop ,your auto fill may be open or stuck

hi dave here.The heatlines that have a silver flexi hose connected to the expansion vessel in the boiler are prone to blockage !! this is one possibilty. Checking vessel is also a must do.
