Sentinel Boiler Noise Reducer 1L is rated 4.9 out of 5 by 14.
Rated 5 out of 5 by from Sentinel is by far the best products to use Cleaned system with x400 for 2 weeks, drained down and refilled with x100 and added this in too. System now better than ever. Nice and quiet too.

Rated 5 out of 5 by from Kettling boiler sorted Once put into the heating system, it took a couple of hours to notice any difference. But definitely works

Rated 5 out of 5 by from Boiler noise reduced Used this after draining and flushing. Cleaned the tank out manually also. Worked straight away, 80% better. Have used this before and eventually the noise came back after 6 or 7 months.At the minute just pleased not to have a banging boiler! At a much cheaper price than competitors.

Rated 5 out of 5 by from Does what it says on the tin, fantastic! Boiler was practically silent within the hour, great stuff, wish I'd found it sooner would have saved me a call out fee.

Rated 5 out of 5 by from Cleared kettling sound on new Bosch boiler We had a new Worcester Bosch boiler fitted and after a few months we could hear a crackling sound only when the heating was on. Cleaned the system with a system cleaner for 4 weeks and then refilled the system with this and the sentinel inhibitor. The noise has now gone completely. All in all, worth every penny.

Rated 5 out of 5 by from Hear the difference in just 5days Can already hear the difference in just 5days; getting quieter every day. Easy to use if you get yourself pouring cap/nozel. Have also used with the X100.
