@Nickfromwales thank you for the comment, there does appear to be a lot of build up, i don't think the system was inhibited after installation until just recently, the installer turned out to be an opportunistic cowboy in the end! the system has been in about 4 years. would you suggest a full heating system power flush, replace the aav, inhibit and then run back up and see what happens?

hi yes, the valve is closed and then backed off a half turn to allow for bleeding automatically, pictures of the offending article is attached now

HI All, i have an LG 14kw ashp powering hot water and central heating in a 5/6 bedroom house approx 350sqm, i have not issues with the hot water side of things, this works perfectly however, the central heating side gives me issues! when the system works well its great and keeps the house warm but at the moment, once or twice a week the buffer tank which is a 50l cordivari version seems to vent all the central heating system pressure out of of the aav at the top. i have changed the valve a couple of times but still have the same issue, anyone have any ideas what the issue/s might be?
