    One of radiators is ticking

    One of radiators is ticking 11th Feb 18 at 4:19 PM
    All radiators are working well with no noise, just the vertical one in the hallway makes ticking noise. either the radiator itself or the pipes I couldn't differ. btw, I bled the radiator air.

    All have honeywell TRVs but the noisy one(vertical) doesn't have Honeywell TRV, instead, it has a conventional one.

    Any recommendation, should I turn the vertical one off?

    I have a worchester combination boiler. Living in 1st maisonette which also has a loft

    thanks in advance

    Ticking will probably just mean that it's expanding and contracting as it warms and cools.

    You shouldn't turn it off, as the radiator without the TRV acts as a heat dissipator if all the others shut down.
    If you are finding huge gaps between your paragraphs and use Firefox, MSE know about the problem. However, they aren't necessarily doing anything about it yet....

    As above, its due to the heating/cooling. Perfectly normal.

    Even the pipes in our loft tick when the heat comes on, makes me feel very comfortable.

    Some TRV's certainly do tick if not open fully. It's just how it is.

    Try opening it fully and see if the tick goes away.

    Metal often ticks as it heats and cools. As above.. it's basic physics and totally normal!

    sorry but, why only one of the radiators is ticking? no problem with others?

    Just to clarify, its not a "problem".

    However, could be down to a different composition of the metals inside.

    At least half a dozen of ours clunk about, the noise is always in the same part of the wall or floor or rad valve. As they're so predictable I've never worried about it. Just assume it's the pipes expanding and contracting.

    I sleeves the brackets with electrical tape to fix this with one radiator. It depends on the cause. Short of checking the obvious aspects, there's not a lot you can do.

    It's nearly always the pipes expanding, rather than the radiator itself.

    If you want to, you can rip up all the floorboards, trace the pipes, and put something like felt in wherever a pipe might be rubbing, when it expands or contracts.

    I just accept the ticking. It lets me know the central heating is working.
    If it sticks, force it.
    If it breaks, well it wasn't working right anyway.

    Whilst we were decorating our new house and had no carpets, we took up a floorboard to locate a particularly noisy pipe. Never mind ticking, this sounds like a gun going off....... every morning. No chance of sleeping through it. Turned out the pipe was being held in place across a joist with a bent nail which was rubbing badly. Nail removed, pipe lagged with some felt, board replaced........... pipe drilled through........ plumber called........ freshly painted ceiling below ruined.........

    thank you, both your suggestions are useful to me and seem to be right. I also got a recommendation from a plumber which is inline with your recommendations, See below please.

    ****
    expansion of either pipes feeding rad or rad itself expanding,pipes in floor going to rad may be squeezed by joists and as they heat and expand because they are tight they make the noise you describe ,or it could be the muck in your system has lodged in this rad,either way it is not dangerous .
    ***

    I have a carpet installed around the pipes which goes into floorboard. I will take it out and check the pipes.
