Rated 5 out of 5 by Top product. Used on my old system and it's back to full working order. I did use two litres to make sure, for £38 it was a cheap cure. 8 Nov 2014
Rated 5 out of 5 by Sentinel X200 Quality product used on its own with a power flush or added to the system with X100, brings a scaled/blocked boiler back to life ( unless the boiler is beyond repair), I personally wont use any other product. 17 May 2014
Rated 4 out of 5 by ok but The product is ok but you need to be patient as it take a few weeks to work found the rapid dose to be easier to use. 1 Apr 2013
Rated 4 out of 5 by Sentinel X200 This stuff works well. I put 2 litres in a 13 radiator system. But I have found it needs another dose after 2 or 3 years. I have an open system. 9 Mar 2013
