5.0 out of 5 stars Fine product
An excellent product recommended by a plumber to use before boiler change. Very competitive price and fast delivery with no problems. Easy instructions, no problems in using it, would recommend and would use again.

5.0 out of 5 stars Great product, 14 Jun 2013

This review is from: Fernox F3 Central Heating Cleaner 500ml (S51463F) (Misc.)
Easy to use, put it in the system and leave it a few days then drained out the gunk. The system is now quieter and more efficient. I subsequently used the Fernox protector to prevent future gunk build up

5.0 out of 5 stars Works brilliant!, 12 Jan 2012
This review is from: Fernox F3 Central Heating Cleaner 500ml (S51463F) (Misc.)
Simple to use on an old back boiler with the tank in the roof, cleans a lot of gunk out too. Unless you looked inside the parts it's hard to tell but I do belive this has helped my boilers efficiency and would definitely use this again.
