Rated 5 out of 5 by from Does What it Says it Does I have an aging Baxi combi which became noisy, sounded like a jet engine in the middle of the night. After injecting this into the system there was an almost immediate reduction in noise, but now some six weeks on the boiler is just purring like a big cat. I cannot be sure about reliability as six weeks is not long enough, buy if it lasts a year it will be worth it. Would definitely use it again.

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.

Can this be used inside single heat electric towel rail?

I want to flush out my electric towel rail and need a replacement product instead of oil. Can I fill with water, Fernox Protector F1 and Boiler Noise silencer F2 ?
Asked by: monkgentry
Hello Monkgentry, you can use a combination of water, Fernox Protector F1 and Fernox Boiler Noise Silence F2 for this purpose.

Usage/Quantity

Is one bottle sufficient for a 10 Radiator system? or should you use more? Will more do any harm?
Asked by: AKJ1
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.

can this product be used with fernox inhibitor

Asked by: oldgit70
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.
