To clean an older system in accordance with BS 7593, this product should be circulated (preferably at normal operating temperature, with all valves open and the pump turned to maximum flow) for a minimum period of 2 hours or until satisfactory performance is restored. Use in conjunction with a powerflushing device to achieve a more rapid clean. 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. 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. 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. 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.

A few examples of the kind of debris that can be found in new systems include copper swarf, flux residues, casting sands and rust. Other contaminants can include greases and stamping oils used in the manufacturing process, sometimes applied excessively. When introduced into a central heating system, these materials can cause problems such as corrosion. The new formulation Sentinel X800 Fast Acting Cleaner is now available in all good plumbing, heating and builders' merchants.

I located the drain valve just outside the property and opened it to drain the central heating system - left it for about an hour 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

COMMERCIAL X800 CLEANER | Sentinel

X300 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 oldSentinel X800 Fast Acting Cleaner should be used as a 1% solution in mains water to remove typical levels of deposits of iron oxide and calcium carbonate. Where systems are badly fouled, a higher concentration (up to 10%) is recommended. 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. 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 I am also planning on cleaning the magnaclean filter, could this also be part of the root cause to my issue?

Sentinel X800 Jetflo Fast Acting Central Heating System

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 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. 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. After cleaning, the system should be drained and flushed until the water runs clear. On refilling, the system should be treated with Sentinel X100 Inhibitor or Sentinel X500 Inhibited Antifreeze.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. To 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.

For large or heavily fouled commercial systems, the cleaning period may have to be extended and the cleaning temperature elevated.

Continues bleeding the radiators downstairs, starting with the closet to the boiler until no water or sound could be heard 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. To clean an older system in accordance with BS 7593 it is recommended that this product is used withpowerflushing equipment. In this scenario, administer Sentinel X800 Fast Acting Cleaner via thepowerflushing equipment, following theequipment manufacturer's instructions. Alternatively, circulate theproduct (preferably at normal operating temperature, with all valves open and the pump turned tomaximum flow) for a minimum period of 1 hour or until satisfactory performance is restored. 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.
