Ok I'll stick some extra into the system tomorrow, it's settled back down to 0.5 bar so it looks pretty good initially. By Iso's do you mean the supply and return valves for the heating loop. Is the doc a local drain within the boiler?? If I'm not sure I'll just get it limping over for now...

Hi I didn't measure the pressure cause there was basically nothing left, quick blast of air when I pressed the needle valve in then nothing, I just put a small amount of air in there to see if I got a pressure increase. I took the system pressure to 0.5 with the water side full and cold on...

Hi folks was on here last month whilst I was away from home trying to figure out what was happening with my boiler. Basically the system pressure was fluctuation between 0-0.5 bar to 2 bar, I've just got back and checked the Schrader valve on the top of the expansion vessel and got air...

Second thoughts ignore that about the TRV, the system worked fine for ages after that, this fluctuation in pressure is only recent. Could it be down to the cold temperatures dropping the system pressure below 0.5 when offline meaning the expansion vessel emptied?

Ok guys I took the front cover off just for a wee looksie there and can't see anything obvious. From what I read in the manual the expansion vessel is behind the boiler and it was precharged to 0.5 Bar. I see a pipe which I think is from the expansion vessel and goes down to the supply or...

Hi guys thanks for the response, the boiler is a Baxi 105E. I take it the expansion vessel needs to be pre-charged to stop the system from flattening?

Hi there, just wondering if anyone can help with a couple of queries. Firstly I have a small leak by the looks of it, i'm having to top my system up at least once a week via the filling loop, luckily it has been left connected losing approximately 0.5-1 Bar over a week, going by the tiny...
