air in system

[marlb]

Can anyone help?

I have attempted to refill my sealed system and have got pressure up to 1 bar after bleeding all rads. I then ran the central heating for a couple of hours and then re bled rads and left the system overnight.

This morning the pressure was back at zero.

There are no leaks so i am a bit stumped.

Any suggestions??

Refill, bleed, refill if ness, bleed again and top up if ness.

If it's at zero again, youve got a leak.

See FAQ's for possible problems with the Expansion Vessel. You may want to check the discharge pipe aswell.
