Rated 5 out of 5 by from Noisey boiler silenced It does exactly what is claimed on the label. Once added to the boiler water circuit all that dreadful noise is gone.

Rated 5 out of 5 by from Perfect Having had a noisy boiler for years, the engineer suggested I try using this product. I read other reviews saying that it either worked quickly or might take 2 months so my expectations were low. Having used the No Nonsense filling kit to inject it into the top of a chrome towel rail/radiator I was amazed and pleased to notice a huge improvement almost immediately. I'm just annoyed I didn't find out sooner! A great product that worked for me.

Rated 4 out of 5 by from Very Good This is second time I have purchased this product. I added it to my heating system just over a year ago and have had no noise from my boiler since, after years of knocking. Great product.

Rated 5 out of 5 by from Worked for me!! Used Sentinel x800 to clean the system first. The knocking and clanging got much worse than before, so drained the system and flushed it twice. Added the F2 and turned the heating on for a couple hours that night. Didn't get woken up in the morning from the boiler, actually can't hear it at all !! woohoo.....

Is one bottle sufficient for a 10 Radiator system? or should you use more?
Will more do any harm?

Answer: 
Hi AKJ1, if all the radiators are single panel then 1 bottle will be sufficient, if you have any twin panels then you will need to add a further bottle. There is no harm in using too much but there is no need to exceed the dose. The dose rate for all version of the Fernox F range of products is one application for every 10 single panelled radiators, if you have double or twin panels then count these as 2 and round up to the next full bottle.

Hello. All Fernox products are formulated so that they can be used together, so you can use the F2 Boiler Noise Silencer and F1 Protector in the same system.
