Rated 5 out of 5 by from Peace and quiet at last. Was recommended this product as my boiler every morning when starting up would make a brass band sound quiet. So I added this product to my system and after a couple of days the noise had stopped. So it's back to the alarm clock.

Rated 5 out of 5 by from Worked straight away! Cleaned out the header tank and added this along with X100 then topped up with water. The radiators now get much hotter and the boiler is quieter too. It didn't take long & I saw an immediate difference.The only negative was the fact that Screwfix use Parcelforce & they did not deliver to me but the post office for one order & to someone I'd never heard of for another despite the fact that I'm working from home & in!

Rated 4 out of 5 by from Great Product I have used this several times on customers boilers and it has worked, but it will not always work. However, it is the only one that will if it can. Try it, it does work but takes time.

Rated 5 out of 5 by from Koncked Knocking Stopped severe knocking on the head in one day. "plumber professionals" quoted several hundred pounds to replace heat exchanger and flush system ... I knew the latter was rubbish as the rads are two years old and system was clean with Magnaclean and X100 stabiliser. Added 1/2 litre of X200 to magnaclean filter, then ran HOT water only for 20 minutes (shorter run and no need to dilute in rads yet). After this Ran CH system 20 minutes. Repeated the above steps 3 more time. Total of 2 litres used in a 18 radiator system. This was 6 months ago, no noise or knocking since.

Do you need to flush the system before adding this, my system is 12 yrs old, have some kettling from Worcester CDi boiler.

Asked by: Bertthegashead
Hi there, X200 can be added to your system without the need of flushing. Sentinel X200 Noise Reducer should be left in the system. Kind regards Sentinel
