Reviews
Central Heating Cleanser / Descaler & Inhibitor is rated 4.9 out of 5 by 72.
Rated 5 out of 5 by from Simply the BEST!! I have used another brand before more expensive and it did very little but this simply worked virtually straight away. My boiler is at least 37yrs old and never had much done to it. It was banging away so I took a last chance at clearing it and PRESTO it worked! I cannot recommend this enough I am going to empty the system and put this in again when it's warmer.

Rated 4 out of 5 by from Seemed to clean header tank a bit Poured in header tank. Seemed to fizz a bit and was reacting whilst making the water appear a bit more clear (it was quite dirty). On that basis seemed positive. Waiting to see if it improves circulation - early days yet.

Rated 5 out of 5 by from Haunted House Creaking noises in the night, clanking and hissing of air? Frightened kids or worse. Telling hubby to go and investigate because you just heard a noise in the kitchen which may or may not have your boiler! Well... I can confirm that this product really is a ghost buster. We have 13 radiators both old and new, a boiler that is 7 years old on a closed system. I followed the instructions on the bottle and drained a radiator subsequently adding the contents of this bottle using a small funnel. I then re-pressurised the system and bled the radiators of air and re-pressurised again. What a difference it made. All those sticking radiator valves cured, no more random noises at night; just brilliant.

Rated 5 out of 5 by from great stuff I haven't heard a whisper from what was our very "banging", noisy combi-boiler since putting this stuff in; and I've tried Fernox F2 - early days though .. (3 days in so far)
