No Nonsense Central Heating Noise Reducer 500ml is rated 3.9 out of 5 by 37.
Rated 5 out of 5 by from Excellent product In my property i have a back boiler with micro bore pipe and for years have suffered with exreme kettling/banging, I was on the point of replacing the boiler and piping. I saw the noise reducer while in screwfix and thought there was nothing to lose especially as it was on offer On putting 2 x 500ml bottles in the system from the off, it is like a new system Totally quiet, no more kettling/bangs I cant recommend it enough

Rated 3 out of 5 by from Not convinced Shortly after introducing this product into my system the boiler starting making kettling noises. I left it for a couple of weeks but finally decided to drain and refilling the system and the noises stopped. Not necessarily an issue with the product but it didn't agree with my boiler.

Rated 5 out of 5 by from Noise Tried this for the first time. A bit time consuming and messy having to partially empty radiator and pour this in but stop the noise straight away! Great!

Rated 4 out of 5 by from No Nonsense Silencer Worked OK Old floor standing cast iron boiler with bad kettleing, I did not expect it to be silent after treatment but I was impressed by the effect, it's still bumping away but a lot less than before, the effect is not instant and it's improved over the past few weeks. I'm considering adding another bottle, but not sure if it's sensible to do so? however if you have an old boiler I would give it a go, it worked well enough for me.

Rated 5 out of 5 by from Excellent value Not used Screwfix before but had a boiler with a kettling problem and thought give a try at this price. After just a few days the kettling has reduced to just a slight level that hoping will improve with time. Combined with the cleaner rads and hot water are warming up a lot quicker then before. Good stuff
