Kettling Boiler

[Nevets69]

Hello,

I have a Potterton Profile conventional boiler that last year was making some horrible noises, glugging, burping and hissing madly like a boiling kettle, and would keep shutting down.

Last February, I drained down the system and refilled a couple of times and added a couple of bottles of Sentinal X200 and gradually the boiler has quietened down. It no longer glugs and burps, but still hisses like an angry snake!

Is it worth draining down again and refilling with fresh X200, or is there anything stronger that's recommended?

Thanks in advance for any advice!

I used to run a Potterton system boiler and that kettled like mad. Cleaned everything out with Fernox F3 for a week, drained twice and then inhibited using Fernox MB-1. Quiet as a mouse afterwards.

Are Fernox products better than Sentinal?

I couldn't say but I can say that I used Fernox and it worked for me

OK Thanks. Maybe I'll drain down, flush and try that.
