Its formulation also contains agents to ensure the protection of system metals against corrosion during the cleaning as well as preparing the installation for the addition of Sentinel X100 Inhibitor.

Sentinel X800 Fast Acting Cleaner eliminates magnetite and limescale deposits from heat exchangers, radiators, underflor heating floors and pipework. It restores more uniform distribution of heat in existing installations, for a better heated home and reduced energy bills. This cleaning agent boasts a powerful yet non-aggressive formulation that helps installers to get the job done as fast as possible - without compromising on performance. The new formulation Sentinel X800 Fast Acting Cleaner is now available in all good plumbing, heating and builders' merchants.

As for new systems, X300 Cleaner for New Systems is designed to target installation and manufacture debris and contaminants. Once cleaned, it will passivate the metal surfaces and prevent copper deposition.

Sentinel X800 Jetflo is a powerful, highly active cleaning agent for use in central heating systems. It is specifically designed for use in conjunction with power flushing equipment and will remove objectionable iron oxide and calcium based deposits from heat exchangers, radiators and pipe work. Its unique composition allows Sentinel X800 Jetflo to act as a penetrating dispersant under neutral pH conditions, eliminating the need to clean with conventional acids and the problems associated with them. The formulation also contains agents to help protect metal from corrosion. If a sealed system (combi, or non-combi but with no F&E tank but with an expansion vessel either inside the boiler or external to it) you will need to add the chemical another way. Often a tall towel type radiator will do. Turn off the boiler. Bleed water from a radiator bleed point until the boiler pressure drops to zero. Take the whole bleed plug (not just the square headed bleed screw) out of the top of the radiator, syphon out 1.5 litres of water and replace with the chemical. Replace the plug, top up the system water to normal boiler pressure (say 1.3 bar if you don't know what that is). Run the system as above. You will still have to do a full drain down and repeat a few times as above. If you don't have a suitable towel type radiator you can get the chemicals in various "easy add" versions. I've never found these easy to use.

Where systems are badly fouled, we recommend a longer circulation period (approximately 3-4 weeks). The product is not aggressive and can be safely left in the system for extended periods. The Sentinel X800 Fast Acting Cleaner can be used in hot or cold systems (older than six months) and is the perfect partner for powerflushing machines thanks to its no-foam formula. The new chemical innovations in Sentinel X800 Cleaner include reducing agents to dissolve adhering corrosion crusts and settled debris, and powerful complexing agents that help retain dissolved corrosion debris and scale in solution. As with all Sentinel products, X800 Cleaner is non-toxic, biodegradable and completely harmless to the environment. I read online that I should have open the bleed valves a bit whilst draining the system. So with this new information I started bleeding the radiators downstairs starting with the one closet to the boiler, which caused more water to come out of the drain valve
