Boiler making whistling noise

[ukheather]

Since it was windy yesterday my combi boiler is now making a whistling noise on and off every few seconds.

It is quite a low noise but does anyone know what this could be?

Thank you

if its whisling the "last post " your in trouble

poss flue or casing seals
cant say why the wind would cause it tho

in fact, its whistling in the wind.

when I said it was whistling I meant now the wind had stopped otherwise, yes I would blame the wind

 

[kevplumb]

so check the flue and casing seals

so check the flue and casing seals

Is that the pipe outside, behind the boiler?

 

[kevplumb]

yup and the silver bit when you take the white case off

 

[ukheather]

thanks, is there anything in particular I should be looking for?

I guess this isn't anything to be worried about then?

 

[kevplumb]

not if its a neg pressure appliance

 

[ukheather]

I don't know much about boilers... what is that?

My boiler is a condensing combi boiler

 

[kevplumb]

you should be safe then

make & model might help

It's a Worcester Greenstar HE

The noise is kind of annoying. It sounds a bit like a bird is stuck in it

Had a look at the flue and it looks same as usual. Nothing trapped or damaged.

Should I be worried and does anyone know what it could be?

 

[kevplumb]

the whistling is air being pulled in through a gap

na dont worry more annoyance than dangerous
