Currently got some Sentinel X400 (sludge remover) in my system. Will be draining down and re-filling shortly and looking at the difference types of inhibitor. Our house 13 rads, looks like 1 litre of Sentinel X100 will protect upto 10 rads. Screwfix have some no-nonsense CH inhibitor (£8 versus £13 for the Sentinel brand). As I need 2 litres I was thinking of getting the No-nonsense brand. Has anyone used this stuff? Is it worth spending the extra £10 and getting 2 litres of Sentinel?

Have a look here:
(I didn't use Fernox, but can't remember what I did use - it appears to have worked OK. But if/when I need to do it again, I shall be looking at those results before choosing.)
Last year I used Fenox - the stuff you inject into the Radiator - worked for me!

How do you know? Maybe you can come back in another 19 years or so and let us know?
I've recently changed the boiler on my 25+ year old system which has used Fernox inhibitor all its life - changed at approx 5 year intervals. And the water that drained out was pretty clear - no sign of the black gunge others talk about. Of course a cheaper one may have worked as well - but I'm not inclined to take the risk.
Bet you'd still have got some squid ink out of the bottoms of your rads!
Yes - I re-sited one rad at the same time and there was some black water at the bottom.
I used the Purimachos inhibitor once. I wouldn't use it again if it was a tenth of the price of Sentinel.
i bought 2 litres of Sentinel X100 in the end. Flushed it out and refilled yesterday.
Nothing is as good as Purimachos inhibitor ;-)
