Corgi Boiler Noise Silencer 500ml Concentrate is rated 3.9 out of 5 by 9.
Rated 1 out of 5 by from Useless Added via my header tank with their inhibitor only to find a horrible gelatinous scum a few days later which I had to fish out. Complained to their technical department and they said I needed to draw some of the system water off to get it to mix. I did that be draining my header tank into the system. Now it makes more noise than it did before !!!!

Rated 5 out of 5 by from Had My Doubts! Having listened to a clunking central heating boiler for the last 12 months I decided to try an inhibitor to silence the constant kettling. I was sceptical anything would work but decided to try 2 bottles of Corgi Boiler Silencer. After draining my system down I added it to the empty F&E tank.& within a week I noticed a huge improvement to the noise levels & boiler efficiency. Very pleased with my Toolstation purchase!

Rated 5 out of 5 by from Top Drop Does exactly what it says on the tin, I added 2 bottles to an ageing old system in a guest house with 16 radiators and it worked a treat

Rated 5 out of 5 by from DOING THE JOB! Added this to my 40 year old system a couple of days ago. The boiler was "kettling" (singing loudly and knocking). Two days on and the boiler still sings (though now much more quietly) and the knocking has disappeared completely so the treatment seems effective. Can be added via radiator or header tank (depending on type of system) and, unlike some silencers/descalers, it can be left in the system indefinitely. It can also be used simultaneously with Cogi branded inhibitor.
