Can anyone offer any guidance please. System installed a year ago. Oil fired grant vortex pro.
Recently started knocking - have read and I see it could be anything from kettling through to pipes.
I attach sound files links as someone may recognise the sound:
Dropbox - Boiler 2.mp3
Dropbox - Boiler.mp3
I plan to test the water for inhibitor - sticker says 3l added.
Many thanks in advance.
