combi boiler problems

[frizzydiz]

have moved into a student house and my radiator keeps banging when boiler comes on. the pressure is at 1 bar is this ok? and how do i stop the banging because it keeps waking me up. plus one of the pipes is dripping on the right of the bolier

Is it an old house? Because I had the same proble in an ancient house and there's not much you can do about it except bleed the radiators as there might be some trapped air in there!

I expect this is expansion clicking, probably where the pipes pass through the floor.

There is little you can do about this.

Any leak should be reported to the landlord or agent and they must be pestered to get it fixed.

possibly trv fitted backwards.

Close the rad valve then open it slowly to a point to see if this stops the banging.

That's interesting, I had a problem with a TRV banging it never used to but at some point started and wouldn't stop. I assumed it was due to the system being clogged up maybe. Anyway, it's been replaced with a new one and initially the new one did a similar thing but appeared to stop after the system was allegidly power flushed. Only thing is I noticed that the TRV is fitted to the right hand side of this radiator. On all the other radiators the TRV or manual valve is on the left and the lockshield is on the right. Is there any convention to say which side the TRV should be on?
Thanks

No,they are bi-directional now. Used to be that you fitted the flow on the right and return on the left however you also had to take into account position of rad in respect of walls & doors etc and indeed furniture and curtains etc.

And, you slightly ran the rad up towards the vent but there is no need to do this now either.

One of the things that does my head in though is the bliddy stupid left handed or right handed installers who insist on fitting the rad vent the way they vent it which means that on some heating rads the vent is fitted hard up against an obstruction with no thought about venting. Probably most of the rads in a particular install are mounted together before hanging but that is really no excuse,IMO.

I dont see many student houses with TRVs.

Not many with gas safety certs either!
