Re: Modern boilers are noisy

You're obviously deaf if you can't hear your burner running.

Dave Plowman (News) formulated the question :

In our case, we have a large kitchen and the space it occupies (in a matching cupboard unit) would have been just dead space anyway.

It is the third boiler to be fitted there, since the original, 22mm pipes + gas were there and for the condensate, there was a drain directly behind it. The location makes it also easy to keep an eye on its operation and over ride the time clock for an impromptu bath, or more HW when required for washing up.

Besides, where else would we put it? I wouldn't want it in the living room, nor the bedrooms. The utility is already pretty full and wouldn't be that useful to place it there.

Noise of the boiler is not that much of a problem, it is barely audible.

Ours was originally in the cupboard under the stairs, we replaced it with one that we put in the attic.

If it was on Paulstradyne mounts it shouldn't vibrate to your house.

I can if I stand next to it. But the ignition whoosh I can hear in the next room.

I don't know what hers is, so cannot comment. I was led to believe the pump was renewed at the time and yes, its upstairs in the airing cupboard. In which case she has been unlucky. The thing is it has made this noise since new and the folk who put the system in claim they all are like that. Brian

Inside my house I can hear water flowing through pipes (the main ones around the pump), but I can't hear the pump itself. I can only hear the pump if I'm in the attic, which is why I hate newer boilers where the pump is in the boiler in the kitchen.

With a condensing boiler you need somewhere for the condensate to drain. Easy in the kitchen, but just having a pipe poking out of the wall risks freezing.

Which 50% seem to have. Don't plumbers understand freezing pipes? Condensate should drain into an inside drain.

I have only ever come across noisy CH pumps, which are faulty/ falling apart internally, otherwise near silent. No they are not all like that, people usually fit new, not because they have failed, but because the pump ha become noisy in operation. Someone is certainly telling porkies.

Max Demian has brought this to us :

I don't think they are allowed to just have the condensate pipe poking out, it has to go to a proper drain.

Thanks for admitting your silent boiler is anything but.

For what reason?

Clearly during the night you need 100% silence. My boiler (pre-2000, no pump or fan) can only be heard slightly when it ignites, and only when burning if you stand right next to it. Quiet enough to get to sleep in the next room, but not if it was in the cupboard right next to me. But other people's more modern boilers I can hear pumping and blowing outside the house, in the kitchen, in the next room, etc, during the day. Very annoying.

The pump itself should be near silent. Most likely it's the water circulating making the noise.

Cite please. There must be many cases were there isn't a 'proper' drain anywhere near the boiler.

In which case you are supposed to build a mini-soakaway. The acid effluent is a possible hazard to children, animals and concrete.

If you're a pessimist.
