I have a `Chaffoteaux & Maury Britony Combi 80` combination boiler. Not sure how old it is (at least 5 years old as it came with the house and I have been here 4 and a half years). It has had a lot of problems with losing pressure over the years so I have called a heating engineer in on a number of occasions, then just over a year ago it lost hot water completely and had to have a new diverter valve (sorry, not totally sure of the terminology). The engineer also serviced it at the same time. In the summer of this year I lost hot water again and prior to this it had also been making a moaning noise from time to time (the closest comparison I can think of is the Wookie in `Star Wars`) so I had another engineer in to sort it - I`m not sure what he did but he didn`t have to replace any parts and everything was fine afterwards.
All was fine for a few months, then recently the moaning started again - occasionally at first, but now it happens whenever I run the hot water. There is also no pressure at all according to the gauge. I have tried adjusting the three valves sticking out underneath, but really don`t know what I`m doing and one of them made the boiler start banging so I decided to leave it alone! I`m reluctant to call anyone out again as it`s fine for a while then starts again, but the house is on the market so I don`t want it to happen for the new owners (not for a few months anyway...). Any help would be greatly appreciated,
Jason
