Central heating pipe clicking noise-help needed

sdd7677

We have got traditional central heating system with the hot water tank in one bedroom (hot water and radiator all run through gas boiler).

There was a noise coming underneath the board in two bedroom intermittently and it get so loud that we (including 2 month old baby) couldn't sleep during the night when central heating comes on. We asked plumber to have a look as I came to know from this site that it must be hot waster pipe expanding and rubbing on joist. He fixed it but the noise started in other bedroom and passage area ( when the central heating comes on). Also, one thing I noticed is it get louder and more frequent during the night.

I am just wondering if someone can help me what can be done?
Does all houses gets clicking noise from the central heating pipes? ( There isn't anything like silent night ?? :mad: )

it happens more at night due the pipes cooling down. and you can hear more/better at night too.
all pipes should be secured/clipped at regular spaces. in the past esp, this was hardly ever done properly. hence all the banging and clattering.

Don't need heating on at night, surely?

plumber told me that pipes need not to secured if it's under the floorboard !!

Its a common problem and even securing the pipes at regular intervals will not stop them expanding and contracting. When this happens the movement is likely to be heard somewhere in the system. I've got used to mine and I suspect that the op will have to as well.

I think you will need to lift the floorboards where the ticking is heard, then will find the places where the pipes are resting on, or touching the joists, floorboards or other pipes.

Where they do touch slip something like a piece of carpet, old towel or some fairly thick polythene between the pipe and whatever it is touching. This will allow the pipes to move without making a noise.

It's something that really should have been done at installation.

Of course don't bend or deform the pipes... you wouldn't want them damaged or leaking!!

As J says but you can also get rolls of hair felt from plumbers' merchants for this job. Wrap this around the pipes, stuff between, wherever you can. This should stop the majority, if not all of the noise, unless there's a particularl place you can't get to. We had this when we moved into our present house, OH identified where the ticking was coming from, lifted the floorboards, used the hair felt wherever it was possible and we don't hear anything now.

Thats the stuff to use. The problem areas are where they cross joists and the lazy installer didn't notch it quite enough. No amount of clipping will stop expansion and contraction of the pipework BTW as 27Col has already said.
