Loud Central heating

[ian413]

Just recently I have been woken up by a loud groaning noise coming from my central heating. The loud groaning stops when I adjust the radiator in the next room. I also have a radiator which has water in it but fails to warm up,any ideas??

trv springs to mind

Thanks for quick answer,sorrymate I'm not a plumber and this will sound like a silly question but,what is a trv?

 

[kevplumb]

thermostatic radiator valve

 

[ian413]

Will this fix the 'groaning central heating'? and how?

could be locksheild is open to much

hard to say without seeing it or hearing it rarther

The trv is on the right side as you look at it. The trv's have been replaced downstairs as the little pin inside seemed to be rusted shut/open and weren't working.Is the trv easy to replace?Further investigation obviously needed, thanks anyway!

[ian413]

The arrow is pointing towards the left

 

[kevplumb]
