Rated 5 out of 5 by from Definitely try this for a noisy boiler! This stuff works great! was about to get a central heating engineer to give me a quote for a new boiler, but thought it was worth a try and very impressed after 4-5 days system was calming down 2 weeks i don't even know the boiler is on. chuffed to bits.

Rated 5 out of 5 by from Great stuff I put this in a convectional twin boiler (non condensing) CH. This was really noisy and had already tried another product that you didn't leave in and it only worked for a few days. X200 has been in for a couple of months now and is still silent. Great stuff.

Rated 5 out of 5 by from Very Effective Works brilliantly and instantly. Think carefully about how to introduce it into your system. I turned off the feed to the header tank, drained half a bucket from a radiator bleed valve to empty the header, added to the Sentinel to the header,then turned the feed back on to refill and bleed the system. Worked instantly,can't hear any noise from the system. I took the opportunity to thoroughly clean the header while it was drained.
