Rated 4 out of 5 by It does work EVENTUALLY Potterton Profile started kettling after 20 years. The pump also seemed to be nosier. Always used Fernox Inhibitor so I guessed it was scale build-up in the heat exchanger. Added Fernox Boiler Silencer and ran for 2 hours. Initially was disappointed as kettling continued however after 3 months the kettling has almost been eliminated. The pump is quieter as well so I guess the flow is now no longer restricted. Give it time and it will work. 17 Dec 2014
Rated 5 out of 5 by WOW We had what sounded like a drum kit in two of the rads in the house it was so loud every morning would wake me up. Within 10 mins of using this product there was no noise at all I was so sceptical this would work having drained the system countless times to no avail - amazed great product highly recommend and really easy to do (complete novice) 2 Dec 2014
