Have tried testing with a match but whatever it is, it doesn't seem to burn readily.
When system was drained for conversion to pressurised system, the water coming out looked clean and fresh.
I should mention this problem has been ongoing now for at least 2 years. Presumably if anything...
Hello:
Sorry to bother everyone again :cry:
I asked a question a while ago about how to deal with air getting into my heating system. The solution recommended here and by others was to convert it to a pressurised system. This I have now done - BUT still the problem persists.

Thanks again for all the responses - especially on a bank holiday!

Thanks for the advice.
In fact another plumber did suggest the conversion to sealed system, but for some reason I wasn't convinced. Being paranoid I worry that the increased presure might cause a big leak somewhere in the (possibly-dodgy) pipework; or alternatively that the air problem would...
OK, Some more info:
Old boiler was a Baxi (Bermuda?) back boiler
New is a Potterton Suprima 40L
Not sure about water content - both similar heat output so may be about the same?
It is a small system (5 radiators) in a top floor flat with header tank in loft
(just above ceiling level).
The...
I have a big problem of air (or some other gas?) in the central heating.
Need to vent radiators every day. Noise of bubbles moving around in the pipes all the time.
A bit of history:
Problem started after the system was cleansed with an acidic cleaner (Fernox DS40)
Has been drained...
I Recently cleaned my system using "Fernox DS40" (plus neutraliser). Drained + flushed 4 times as per instructions, then refilled + Fernox protector added.
Ever since, it continually fills with air and needs venting every day. Only happens when the boiler is hot, no problem when the stat is...
