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
Rated 5 out of 5 by Easy and safe It is not as quick as the acid cleaners, but is much easier and safer to use. I have had damage to skin and clothes from spillages of acids, and you have to rinse and flush them out very thoroughly. X200 is mild and seems harmless, and you don't have to drain it out or rinse it - you leave it circulating in the system permanently. It works faster if you add it in summer when the radiators are all turned off, then it is more concentrated in the boiler HEX and hot-water system because it does not mix with all the water in the radiators. It may take a month or two to achieve its best You may need two bottles if the system is very large or scaly. 17 Dec 2012
