      Sentinel X400

      This cleaner has done a great job on my 30 year old system. I flushed our the system first, added the X400 into the header tank in the loft as it was refilling and left it in for a couple of weeks. I thought the flushing had removed a lot of gunk, but so much more came out after using the X400. I've now flushed it again and added inhibitor, the whole system is quieter and heats up much more quickly, with no cold spots along radiator bottoms. In my experience, this product had worked better than others I've used in the past.

      Cheap , effective alternative to power flushing .

      I have used it in the past so I know what to expect . It's easy to use and very affective and here's my tip , leave it circulating for a few weeks or months to get the best out of it , it won't do any harm .

      Impressive product

      2L into 5 bed-house heating system and a couple of days later a really noticeable decrease in cool spots at bottom of several radiators which I'd guessed were due to sediment

      Rice Crispies in the boiler?

      Cured system of pops, squeaks and wheezes. Pump seems smoother now
