Gas pipes noise

[James01]

Hi, we have just had central heating installed for the first time and I honestly wish we hadn't. Firstly, I didn't realise combi boilers made a constant noise, we live in a bungalow and the boiler is in the bathroom next to my bedroom so I can hear that all the time then to make matters worse the gas pipes into my room have had to go in front of the skirting boards and I get a constant woosh noise from them. The fitters have said there is nothing I can do about it, it's normal and can only be installed that way. I'm sure there are other people with the same problem but it seems there is no solution apart from ear plugs!

Not sure about the woosh, but if the boiler has an 'eco' setting, that will stop it from coming on during the night.

I have never heard a gas pipe make a noise before unless I'm working on it. With regard to constant noise as JC says Eco setting will stop the hot water pre heat. Also decent controls and time settings for the central heating will minimise the noise of it operating. The installer should be able to explain the controls to you to enable it to be less of a nuisance. Also consider insulation or soundboard in the compartment the boiler is in to reduce noise. The installer should be able to advise on this also.

Thanks for your replies, I don't think it's got an Eco setting, it's the Baxi promax 28 titanium. I can't understand the pipe noise either, it sounds like the pressure of the water running through. The pipes in the kitchen are above the floor and they are silent but the bedroom is right next to the boiler so I don't know if that's the reason. I'm sick of being told it's normal by the fitters. The timer has yet to be fitted so maybe that would make a difference? Sorry I am totally clueless about central heating.

Post a few pictures if you can

Hi,
You mentioned this unwanted noise.

I didn't realise combi boilers made a constant noise, we live in a bungalow and the boiler is in the bathroom next to my bedroom so I can hear that all the time then to make matters worse the gas pipes into my room have had to go in front of the skirting boards and I get a constant woosh noise from them.

From your description it sounds more like you have x2 pipes running across your skirting boards to a radiator.

The noise can be air in the pipes/system or potentially if the pump speed is set to high you would also get this noise due to the fluid speed through the pipes.

The system should also not have been installed without a timer/room-stat/trv's to meet building regs.

As you have no timer and as mentioned above the boiler may be firing during the night quiet hours waking you up.

You need to get the installer back to sort out for you and to ensure that they meet the building regs.

Have you got the manufacturers instructions with the benchmark document filled in & also checked with Gas Safe/building control or manufacturer to see if the boiler has been registered yet. That may answer some of your questions if it has not been filled in or registered,

Thanks,

Andy

Thanks Andy, that's it x2 pipes to radiator, so do you think they should be silent? The timer should be fitted tomorrow, the boiler has been registered and I will check the documents. If we set the timer for the heating to go off at say 10pm then come on at 6am should the boiler be silent during those hours that no heating is on. Sorry, I must sound thick but it's all new to me.

A combi will preheat avery 30 mins or so through the night (and day) regardless of if there is a call for heat or hot water.
That's what the eco mode is for, it stops the preheat, the downside is that when you do open a hot tap, it will take longer for the water to get hot when in eco mode.
If there is no eco mode then I'm sorry to say you will get the preheat noise even through the night.

Boxing the pipework along the skirting may help.

Thanks for your replies, I noticed that the pipes from the boiler at work are lagged with a foam tube, do you think that lagging the pipes that lead to the radiator would reduce the noise at all?
