falcon ferolli 11 combi boiler pressure in, no pressure coming out?
had a leaky underground pipe my partner fixed it but in the process i think he got some dirt or something in the pipes and now i have no hot water, their is pressure going into the boiler but their is very little coming out, i have been told it might be the heater exchange blocked, so i need to find out how to unblock it, or if you think it is something else.
Wouldn't recommend tackling the heat echanger.That usually involves going into the combustion chamber and thats gas /corgi only.
Before you go for bigger problems there are other things to check. Is the cold water all over the house still good pressure?
If yes the boiler cold inlet feed pipe may have a filter in it ( most do). Not too easy to get at on this model but you should be ok if he managed to repair a mains leak..
