Working good, hotter water, Simply place in condensation water tank.
Great product. My Vaillant boiler had really started to bang and pop loudly so I added Sentinal X200 and the noise stopped almost immediately. Now 6 weeks later it is has started to pop again but very lightly, so as advised by Sentinal I added another bottle which I got from Toolstation as they had the lowest price and it was in stock. I added the whole bottle and within an hour no noise. BTW the system filter had lots of black bits
Had my boiler serviced by an engineer and I decided to add this to the header tank (vented heating system). Time will tell what impact the Noise Reducer will have but thought it was worth a try.
Good value, useful product value for money. Excellent service at Toolstation
Remarkable ‘stuff’ - I bought this after reading about it on line and thinking that it would be worth a bash to try and stamp out the clattering and banging coming from the boiler that sounded like kettling.
It took less than five minutes to drain down enough from the system to permit pouring the fluid in directly to a towel rail and less than a minute to top up the whole system. I used two litres as I have more than the suggested maximum of ten radiators per litre and am delighted to report that, three days on from the use of the product, all has now become quiet in the boiler and the pipes !
I have no idea if it works as it has only just gone in.
Excellent product would highly recommend does exactly what it should.
Our boiler had been kettleing and making loads of noise. After a bit of research I got the x200 before spending loads on a plumber. Happy to say it seems to have worked. Odd noise now and again but it's only been a week.
Great product I always use this because it works and at a very good price at my toolstation thanks.
X200 works for a year but needs replacing to keep kettling noises down.
Great product I have used many years ago to make a Combi boiler quieter. Recently changed the radiators and the system became noisy again. Added X200 run for a couple of days and system is quiet again.
Small improvement upto now, manufacturer says it can take a few weeks for full benefit.
This made an instant improvement. It’s good stuff.
I live in a hard water area, which causes the boiler to become noisy with age. This has been added when I've noticed noise and it has always silenced my boiler. Great product that has extended the life of my boiler at little cost.
This is easy to use and works well. I have an older, open system, so I just drained a couple of gallons, added it to the header tank, refilled and all done. Boiler kettling noises disappeared quickly.
Stopped kettling boiler in a week. Tried a different product before but this works much better, tho took about a week to get the boiler sounding normal again.
Added this after cleaning out the header tank and having drained off some water first. Takes time to work, about ten days, but does the job. Kettling noise much reduced. May need doing again after a couple of years.
Great product, does silence boiler knocking, i find that i have to use 2 on my system.
A great product that I have used to help to make Boilers run without making a lot of noise.
