Boiler/tank noise

[photolimbo]

Hello

Our boiler and tank was recently recited during a loft conversion. They're now just outside our bedroom wall and are very noisy! How noisy should they be? Know its hard to describe witjout hearing them but they're loud enough to wake us up. I have tried speaking to the plumber but he seems to think that noise level is normal but I feel like I'm being fobbed off.

Anyone had similar experience? Thanks

When it fires up do you mean?
Our boiler is downstairs but if I wake up early in the morning and it suddenly kicks in I know it’s 5:30am because that’s what time its set to come on, so it is audible. I do sleep with my bedroom door ajar though.
If it’s the other side of your bedroom wall then you will hear it, especially in the dead of night, but it will be the same as I can hear ours if I’m in the next room downstairs.

Did you never hear it at all in the old place, never think to yourself ‘oh, the heatings kicking in’ as it fired up?

So do you have a boiler plus 2 tanks and a cylinder or is it a combi?

Boilers are noisy. Our boiler would wake me up if it was upstairs.

A boiler and a megaflo tank

It used to be in the loft at the back so never really heard it. Now we have converted the loft, it is above the stairs behind the bedroom wall.

Boilers aren’t particularly quiet appliances. They have various solenoids and valves, plus there’s the noise from the gas burners, electric fan, radiator pump plus hot water moving around the circuit.

Yes, I'm aware they make noise, just wondering if there's something wrong with it/making too much noise

I totally get that you are hoping it’s making too much noise so that the noise can be improved in some way.
I think, sadly, the reality is that it’s been checked and they’ve said it’s fine. You will either have to learn to become accustomed to it (you will, in time!) or invest in earplugs.

Yep, ours is in the kitchen but on the wall to the front room, and it makes a racket! I did wonder if those wooden acoustic panel things would make a difference??

We have just switched to a combi from an old conventional flue boiler in the kitchen chimney. The combi is in the former airing cupboard in a room someone sleeps in. It's really quiet and doesn't disturb anyone.

OP it might just be a noisier system or one not suited to where it's been reinstalled.

Is it the unvented cylinder/megaflow making the noise? If so it might need recharging (you’ll need a plumber to do this). We needed to do this with ours about 6/7 years ago. It was making a lot of noise.

Ours is in the kitchen. I'd say the system hums, but not that distracting that say I'd need to turn tv up in in the next room.

Gas boilers can make a roaring sound and there is the sound of the fan too.

But mine is not that noisy although it is a long way away from where I sleep.

If the tank and pipes are making noise it could be due to trapped air in the system that needs to be removed. This is common in a new installation. Have you tried bleeding the radiators
