Loud clunking noise from hot water cylinder

[MGR]

Hi,

Hope i can get some advise regarding this issue. As the title says am getting this loud clunking noise from my hot water cylinder which appears to happen when the hot water is on or hot water tap is running. It only recently started last few days. The system is a Kingspan Tribune XE unvented.

Its a new build house and only moved in August, its still under warrantly. I reported it to the house builder who got the company who installed it to come out and have a look, the guy who came didnt seem that interested in the noise and said it was a valve opening and closing,

I have recorded the noise but just in the process of editing the video as its very long to upload.

I will be going back to the house builder tomorrow to ask for someone to come out again, but just wanted to know if anyone experience this before and how it was fixed please?

Hi - I have a similar issue with Gledhill 300l unvented Hot Water Cylinder. How was this resolved?

Did you find out what this issue was? I have the same thing and the installers washed their hands of it but it's getting louder. Thanks.

Sounds like expansion, Try when water is cold and see if it happens then might narrow it down a bit.

Thanks Pete, I'll try that. I'd turned off all cold feeds to the mixer taps last night as we don't have balanced cold water yet in case it was pressurizing back through them but no such luck!

Thanks for the response, An engineer from the housing company came out yesterday and stated he recharged the cylinder but its still making the noise. finally uploaded the video this si a 18 minute video cut down to under 1 minute to show how often it happens



I will call them again today to come have a look again

Hi did this get resolved I’m having a similar issue?

Hi Brutos,
We have the same problem. If yours was solved, could you please share what it was and what needed fixing? Many thanks.

We were told its the expansion of the actual cylinder flexing.
