    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.

    Some pics:

    Thank you.

    Pics should be fixed. I deleted the originals as they had my GPS coordinates in the EXIF data. #schoolboyerror

    Does the sound come from inside the boilermate?

    Yes, as far as I can tell.

    Possible squeaky pump? They are quiet loud when running though.

    I have lived here for 12 years and I have never heard it until recently.

    We are in a hard water area, could it be a build up of limescale?

    Really appreciate your help. Thank you.

    Probably just the bearings on the pump. Can you video the noise.

    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
