Central Heating System Noise Reducer/Silencer 500ml MC2

I had kettling voice from my boiler so I bought the silencer hoping it would help. Because I had 15 radiators in my house, I bought 2 bottles trying to make sure I got enough dosage in the system. When I put the silencer into my central heating system, silence did not come. After 2 month, it made little difference! I decided to try a different brand of central heating silencer. This time I just bought one bottle to try it out. As soon as I put the new silencer into my central heating, I noticed substaintial differences. My boiler are much quiter now. So my conclusion is this MC2 central heating system noice reducer/silencer is not effective. Don't waste your money and time on it.

Good price and rapid delivery.

all good
