Rated 5 out of 5 by from Excellent Product had to drain down the system to move and change a radiator, first time system had been drained down in 20 years, had added this originally when system installed and water that came out was clear straw colour no black sludge or gunge, even took another radiator off to double check as did not believe. If this added this time around is as good as the original its excellent it does seem to make the system run quitter. Maidstone screwfix excellent waked in and out again 5min later deal done excellent staff on duty young lady who served excellent.

Rated 5 out of 5 by from Still the go to product for CH This has long been the go to product for central heating corrosion inhibitor where there is an open header tank. Used in existing systems for over 30 years it has not failed - they are still running as well as ever - including the boilers! Maybe not PC re energy efficiency but it just shows how good this product is.

What is the difference between the MB1 and the fernox f1 protector?

Asked by: CPESron
Hello CPESron. The main difference is the dosing rate. F1 Protector is a higher concentration, so is dosed at 0.5%, whilst MB-1 is dosed at 4%. Both are compatible with each other, so there is no need to worry about mixing them. Hope this helps.

Can I dose via radiator?

Asked by: Gizmo62
It will be quite difficult to dose via a radiator as the dose rate is 4% of your system volume (so 4 litres for every 10 single panelled radiator). You may find it easier to use Fernox F1 express which can be injected in directly (dose rate of 1 can for every 10 single panelled radiator)
