Pressure?

HelpHim · Posted: Tue Mar 21, 2006 12:09 pm Post Subject: Pressure?

Old (upstairs) radiator was leaking, so I switched it off and left it for a while because I was going away.

Went away, switched the central heating off. Came back, central heating not working. Not firing up.

Bled the radiators. Downstairs - no problem. Upstairs there is a gush of air but no water (is the air gushing in or out?) After bleeding (I think) the central will fire up - but it does not last.

I have now removed the old radiator and capped off the TRV end which was dripping a bit.

Any idea what is going on with the Central heating, is it to do with water pressure or air in the system, and does it make any difference to how I should proceed?

Hi Jamie,

Sorry to be a dunce but I don't know. I've got 6 radiators in a three bedroom house. A back boiler (Baxi Bermuda) and a hot water tank and a cold water tank in the loft. Does that help?

Hi Jamie,

I checked and there's very little - an inch. So the ballcock is hanging in the air above it.

Despite this the central heating did come on last night. But something is obvuiously wrong what should I do now.
