Hi all.
My boiler has been making a racket for nearly two years now.About a month after it started i drained and refilled the system with X200.The drained water was pretty clear.The performance was minimal.After about 6 months i drained the system again an put in some x400.Voila.The noise nearly stopped,so i left it in until last october as i was due to have some work done on the system anyway as circulation was poor(convert to 2 pipe system& some new rads added).The plumbers who did the work gave the system a power flush after work was completed and added a normal inhibitor.No noise for about 3 weeks and then it started again.The system is working absolutely fine.It's just the bloody banging is driving me nuts.I know its probably a large deposit of limescale on the heat Ex plates.
My question is (finally) is it ok to put in some more X400 and just leave it in there forever more? It's the only thing that seems to work? Don't think it's acidic?
Thanks for your time.
Dave
