Sentinel - X800 Fast Acting Cleaner 1L, targeted central heating system cleaning inside an hour, restores system efficiency by targeting corrosion debris, ideal for hot and cold systems

Product Information

X800 Fast Acting Cleanershould be circulated, preferably at normal operating temperature, with all valves open and the pump turned to maximum flow for a minimum period of 3 hours or until satisfactory performance is restored. Sometimes a more general clean is required, aimed at removing iron oxide and limescale deposits from pipework, heat exchangers and radiators. X800 Fast Acting Cleaner is ideal for these purposes, designed for use in conjunction with powerflushing equipment, but also proving a highly effective cleaner when manually flushed, too. It is effective both hot and cold. When might I need Deposit Remover? If the radiators are hot at the bottom but cold at the top, the issue is more likely to be air than sludge in the radiators. 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. 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.

If the deposits you are dealing with are proving to be particularly stubborn, not remedied by the application of the aforementioned cleaners, a more potent product may provide the solution. Sentinel Deposit Remover is a mildly acidic formula designed to dissolve obstinate magnetite and scale deposits. 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. A good cleaner is Sentinel X400, or X800 which is somewhat more aggressive. X400 can be left in the system, but will cease to loosen sludge after about 4 weeks. X800 should be circulated and the system drained and refilled several times to remove it. Fernox and Kamco are reputable makers of similar products. I located the drain valve just outside the property and opened it to drain the central heating system - left it for about an hour

The new formulation Sentinel X800 Fast Acting Cleaner is now available in all good plumbing, heating and builders' merchants. Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point. In this scenario, your customer may struggle to understand how the system could possibly need cleaning. New systems can easily succumb to debris during and after installation as a result of carelessness in the manufacture and installation processes. For details of how to dose using the Rapid-Dose format of this product, please watch the Rapid-Dose video. 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.

Thank you all for your advice, I have tried to do what I can to resolve the heating issues I have been having. So just to paint the picture I will layout the mistakes I have made as somethings that should have been obvious simply wasn’t to me. Continues bleeding the radiators downstairs, starting with the closet to the boiler until no water or sound could be heardTo clean an existing system in accordance with BS7593 it is strongly recommended that Sentinel X800 Jetflo is used with power flushing equipment which will provide a more rapid and effective clean. In such case, Sentinel X800 Jetflo will be administered via the power flushing equipment (follow equipment manufacturer'gs instructions). Alternatively, Sentinel X800 Jetflo should be circulated, preferably at normal operating temperature, with all valves open and the pump turned to maximum flow for a minimum period of 1 hour or until satisfactory performance is restored.

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 valveX300 Cleaner for New Systems is designed to target excess flux residues, greases, and oils in addition to installation debris and sludge. Not only this, but X300 passivates the metal surfaces and helps to prevent copper deposition, a common cause of pinhole corrosion in radiators. Ideally, the product should be added at the first filling of the system. The water should then be circulated at normal operating temperatures for 2 hours before being flushed out. If you are using cold water, leave to circulate for 24 hours. Powerflushing is not necessary when using this product. The system I’m dealing with is not new, but is less than 6 months old I bled the towel radiator in the bathtroom and then siphoned some water out so I could pour in 1L of Sentinel X800 The circulation pump of the system can be used to circulate the cleaning solution; however equipment which provides a more rapid circulation can provide a more effective clean. When using an external cleaning rig, the product can be dosed directly to the buffer tank of the rig (follow equipment manufacturer’s instructions). I went upstairs and started bleeding the radiators there too which caused water to come out of the bleed valves on the radiators downstairs that I had left open

If a system has not been cleaned prior to use, all of the aforementioned issues for new systems will be present, with the installation debris causing issues and damage to the system. In this scenario, the system may benefit from a manual flush using with X300. The system I’m dealing with is older than 6 months

It is recommended thatX800 Fast Acting Cleaneris used in accordance with standard cleaning and commissioning protocols such as BSRIA Guide “Pre-Commission Cleaning of Pipework Systems”. For large or heavily fouled commercial systems, the cleaning period may have to be extended and the cleaning temperature elevated. A constant flow of water kept on coming out of the radiator that is the closet to the drain valve which confuses me as no more water is coming out of the external and only drain valve 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.
