Reviews
Central Heating Descaler / Silencer 1L is rated 4.8 out of 5 by 4.
Rated 5 out of 5 by from Thank you Qual Rad for Silencing my boiler ! About 15 year old system boiler was kettling - tried Sentinel X200. All it did was change the note. Agree with another reviewer (somewhere) that only an acid can dissolve chalk deposits in your boiler (and system). Anyway, flushed out the X200 and loaded up with Qual rad descaler and the boiler sounded 'smooth' from the first firing up. Sounds like new! Only thing against it is not leaving it in the system longer than a few days, but it IS worth it if you want your boiler sounding sweet.
