Hi everyone,
I have not long had a combi boiler installed within the airing cupboard, and it is really noisy. The airing cupboard back on to the main bedroom and is merely partition by scrawny plasterboard walls. Behind the airin cupboad in the bedroom are some built surrounded by cupboards. THis seems to be amplifing the humming of the CH pump and is really annoying and nouns.
I have jammed aload of remaining underlay down the wall but this made little difference. I surmise the noise is more of a juddering / resinence off the wall.
Has anyone get any ideas of how i could lessen the noise? I be thinking of taking the boiler off the wall and wedge some acoustic foam between the wall mounts of the boiler and the wall. The simply problem with this is the plumber wishes to charge me lb200 to take the boiler bad the wall.
Any ideas???
gratefulness
Answers: Absolutely do not fill the wall up near expanding foam. This is intended for small gaps solely, and will probably distort the whole wall. It also will not set properly contained by that kind of volume, and will verbs to release gas for months to come.
It's definitely a well-mannered idea to find the installation checked as suggested by the poster above. If that doesn't solve the problem, this is my best crack at a solution:
If you can't stop the boiler vibrating, you have need of to limit the resonance of the wall. At the moment it's acting similar to a soundbox - making the sound louder. You could try padding the cavities surrounded by the plasterboard wall with vermiculite or Micafil as it is sometimes particular in the UK. It's a lightweight granular insulation textile sometimes used in lofts. It withstands temperature of up to 1000 degrees, so should be fine at the back a boiler. It's a similar weight to the polystyrene ball you get surrounded by beanbag chairs so should have no structural implication.
Here's a link to some blurb roughly speaking it.

It's pretty cheap, non toxic, easy to knob, and comes in heaps. You'd have to cut holes contained by the plasterboard at the top of the wall between each stud and pour it surrounded by. Then patch and fill the holes you own cut in the wall. The most key bit would be the area directly behind the boiler, but the more of the wall you full up the better it would be. If you filled the unharmed cavity my guess would be that it would kill the majority of the resonance surrounded by the wall.
The other thing you could look at is Mass Loaded Vinyl. It comes within sheets approx 1m sq, and you'd have to paste it onto the wall, with no gap. It's expensive though, around lb30 for a good point sheet so you might decide getting a plumber to rehang the boiler over some nice of damping division is cheaper and less hassle.
I've found a connect which corroborates my suggestion:

Fill the partition wall up near Expanding foam ,this will sound proof the wall.
