Whistling flue

[Lancstree]

My Dad has a stove with a flue liner and cowl. In the wind it whistles and makes a sound like someone blowing on a milk bottle. The sound carries right through the house and keeps him awake at night. The only thing that stops the noise is opening the stove door which you can't do when its lit really.

 

Has anyone experienced something like this and what did you do to solve it?

what kinda cowl?

[ThrustSSC]

There's a leak somewhere in the system where the air is blowing across a resonance tube - just like blowing across a milk bottle.

 

My first checks would be the flue itself (perhaps the door is sealing so well that a gap is being pulled open in a join later up the gas flowpath?) and the stove door (perhaps there's a gap there?). The door is the easier to check, so perhaps smart to start there?

 

A few things that might give clues: is it happening immediately on lighting, or does it develop later; does it happen on any stove air vent setting; is it low in the system, or high in the chimney?

Is it an Esse stove?

My Villager whistles some days, although not overly loud it's enough to get a bit annoying after a while, on mine it's because all the door seals need doing, gets worse as the fire gets hotter.

Lined flues will carry noise a lot more if they're just hanging free. The noise transmission is reduced a lot if it's insulated with vermiculite, is it?

 

The other thing is the cowl, or the lack of one.

Change the cowl if you can do so easily for a different type, the ones with a band around them are quite good.

Its a clearview stove, fitted around october this year so very new. The chimey cavity is packed with vermiculite around the flue. The cowl is a very simple one with a rain guard. Seems like it could be a lot of different things. The door seal seems intact.

try turning the cowl round sounds like its coming from the top to me.

maybe a rotating cowl or a spinning one?
