How to silence noisey CH pipes?
Discussion
Since the weathers started to get colder and the CH has gone on the cooper pipes under the floor of my sons bedroom are making a right racket, leading to him waking in the night when the pipes heat up.
I've bled the system and there was very little air expelled so it's not air causing the noise. Definitely more expanding and contracting type of noise.
Short of lifting the carpets and floor and lagging the pipes and making sure they pass through decent sized holes in the joists are there any options to silence the things?

probably easier to silence the kid
tell him if he keeps complaining you're going to put him in a childrens home

Or, get a heating engineer in, but chances are carpets and boards up is more appealing than ceiling below down??
Bad install is usually to blame, or if you've had a leak that has expanded joists/boards. Is this the first year in the house that it has been noticed?
Aye, I'd start by turning the pump and water temp down. If not, if you can get to ONE joist where the pipe passes, and pad the pipe all round, it can fix it.
Or, last easy fix - hang something heavy (like a diving belt weight heavy) from the pipe where you can get to it - I had to resort to that when my living room started cracking, creaking, and generally being annoying.
Worked a treat, but I only had one weight (due to not being a diver), so the bedroom got padded at the joist where I could easily lift a board.

My heating is pretty quiet apart from a single pipe that runs to the rad in the study next to our bedroom, I think the pipework is expanding and hitting the underside of the floorboards, as when you walk into the study the radiator makes some nice creaking and banging sounds.
Foolishly, I didn't fix this before the carpets went down last week.
I'm just going to suck it up though, its a 70's build with retrospective CH, it could have been a lot worse.

We have bad kettling at the moment occasionally forcing the overheating circuit to trip, but our boiler is getting on 15years and a replacement heat exchanger is over £500.00 due to a lack of parts out there.
So I am going to have to bite the bullett and have a full system powerflush at £800, that will either fix it, or result in BG Homecare fitting a £500 exchanger anyway.
Hopefully, you get away with £100 of labour and lagging.
I would say houses are expensive, but Audi and Mercedes charge over £400 for a first year service (read oil change), and both cars is worth considerably less than the house.

If you're forking that out for a flush to solve the issue, can I interest you in some magic beans or snake oil - same price and guaranteed to help!So I am going to have to bite the bullett and have a full system powerflush at £800, that will either fix it, or result in BG Homecare fitting a £500 exchanger anyway.

Yeah, fundamentally the problem is hot pipes against the joist, unsecured pipes moving with the pump of water or plain old expansions/contracting. Nothing short of drastically reducing the water temp or cutting into The flooring and wrapping insulation round the pipe will really solve it I'm afraid! Flushes /inhibitors etc won't do it.
Last house i had it on warm-up, current house has it on cool down. A particularly annoying large knock every several minute for an hour is what I put up with.
During our kitchen renovation I took pics of whilst the ceiling as down, so the frustrating thing is I know the pipe, know the joist and know the location of the expansion of the joists.... I just haven't got the balls to start cutting for fear of the wife's wraith!!

It's also 16 rads, so that's reflected also.
I had the cracking on heat up and cool down on the 22mm pipes running the length of the house, front to back. Caused by expansion and contraction on such a long length of pipe.
I tried packing out the joists, which worked to a degree for a short while, but it wasn't a fix.
So I cut out the lengths of copper along the landing, where there were no T's off to any radiators, and replaced it with plastic. This separated the two copper end pipes, reducing the amount of expansion movement that they needed. The plastic won't expand like the copper does, and if it does then it will just sag down more.
Never heard the cracking pipes since.
If you go this route then run an earth cable alongside the plastic pipes and connect it to the 2 copper pipes at each end to ensure earth continuity.
