my unvented cylinder system has been losing pressure. So I started the investigation as to whether it is losing pressure due to hot water or heating.
So waiting for spring / summer when I don’t run heating much.
I can see that only one of the radiators which I need to bleed as it is always cold at top.
So when I bleed one of the radiators I get more gas (not hydrogen ) I found out that system losing pressure to half bar.
if I don’t run heating the system is not losing pressure and stays one bar.
I can’t see any leak anywhere.
How do I fix ?
Replace the radiators ?
Why is there a gas from One of radiators very often ie every two days.
Appreciate expert advise
