hi

bled my rads when the heating was on and now they aren't working hardly at all (downstairs) - assume that the pressure needs topping up in boiler but i don't know how to do it
there is also no pressure gauge when i open the front door of it (only a display) so can't tell how low it is - it use to blow a lot of condensation outside the vent when it started up which it isn't doing at present. rads up stairs appear to be working fine
how do i top up the pressure - any help greatly appreciated. Many thx in advance. a

I think this is a vented system so there in no pressure to set etc. make sure your header tanks are not empty due to stuck or frozen valves.
