[stuartggray]

Any recommendations of which one to use?
Can anyone explain how they work?

Cheers !

Have always found sentinel x200 is better than the products that are labeled silencers

I believe they raise the boiling point of the water.

Fernox....used it twice on old cast iron boilers ......I understood it coats the surfaces and stops the bubbles of air forming
