Rated 5 out of 5 by from Worker a treat! Older cast iron heat exchanger boiler was singing. Adding this stuff quietened it down within a couple of days.

Rated 5 out of 5 by from Like Ronseal, does what it says on the bottle. Bought this as read some reviews about it online. I have an ageing Oil Boiler system in the house which was making a right racket. Used a couple of bottles of this and the noise has reduced dramatically. Took about a week for the effect to be noticeable but very pleased with it.

Rated 5 out of 5 by from It worked for me - easy I am always a bit doubtful about 'magic' products in a bottle but I have used Fernox products for over 30 years so thought it worth trying, my boiler is over 15 years old and was still banging and popping after descaling for the first time in over 30 years. I drew some water off the bathroom radiator and put the bottle in there - the header tank is hard to get to - bled the radiator and turned its thermostat on full, then ran the heating for two hours to circulate the mixture. The boiler gradually got quieter over a couple of weeks use. Now, after two months, I haven't heard even a pop out of the boiler while it is running, just the noise of the gas burner. I bought a second bottle because I wasn't sure that 1/2 litre would be enough in my system, but one has done the job. This is a great product and was worth every penny for me,the noise from the boiler was really annoying. Well worth trying.
