Hi,

Our heating system has started whistling very loudly when the shower is being used.

If I run a cold tap, the whistle stops immediately.

If I run a hot tap, the pitch of the whistle changes.

The noise is not coming from the boiler (Ideal Icos) which is in the kitchen, it is coming from the 'tank' (A-Class BoilerMate OV) in the upstairs airing cupboard.

The heating system was installed 12 years ago ('new' build), but the shower which is a bar-type, was only installed about year ago (replacing a previous bar-type shower)

It only seems to happen first thing in the morning.

Any thoughts?

Thanks

Possibly the ball valve and float in the hot water tank in the loft?

Hi,

I don't have a tank in the roof/loft, but there is a small tank in the airing cupboard on top of the main tank. It looks pretty grim inside.

Morning,

In true style it did not make a sound during the first shower use, but it did on the second.

I recorded it with my iPhone microphone pointed at the base of the BoilerMate, near all the pipes.

0-10 seconds is normal/background. No water running.
@ 11 seconds: I ran the bathroom sink hot water tap.
@ 55 seconds: I turned the shower on.
@ 5 min 31 seconds: I turned the shower off.
@ 5 min 57 seconds: Something ?pump? switches off.

Looks like this site does not support uploading audio file formats, so I have renamed the .mp4 to .pdf in order to upload it. To replay the audio download it to your PC and rename it back to .mp4.

Thanks

Hard to say. It could still be a pump problem but Personally I would be looking at getting a pro in.
