• Cleans heating systems in as little as 1 hour: Sentinel X800 begins breaking down sludge, magnetite, and scale deposits within just one hour of circulation. Ideal for blocked or noisy systems where time is limited or power flushing is required
• Improves efficiency and helps reduce energy bills: By restoring heat transfer and flow, X800 helps your boiler and radiators run more efficiently. A cleaner system heats faster and uses less energy, supporting lower heating costs
• Use before inhibitor dosing: Use X800 before applying a central heating inhibitor such as LavaTap Sentinel X100. Cleaning first removes debris that can block inhibitor action and ensures full protection against future corrosion
• Fixes common faults: Cold spots and boiler noise X800 rapid central heating cleaner helps resolve common issues like cold radiators, slow circulation, and boiler kettling. It is a fast-acting solution for systems suffering from performance drop due to internal build-up of sludge and scale
• System safe: Safe for sealed, open-vented, and combi boilers. X800 works with aluminium, copper, steel, and mixed-metal systems, making it suitable central heating sludge remover for both modern and older installations
• High coverage: 1 litre treats up to 100 litres or 10 radiators. Formulated for standard domestic systems, one bottle treats up to 100 litres of water. Apply via radiator, filling loop, or dosing point. Flush thoroughly after use and follow with inhibitor

LavaTap Sentinel X800 is a high-performance central heating system cleaner designed to break down internal sludge, magnetite, and limescale. It restores water flow, improves radiator efficiency, and helps resolve common issues such as boiler noise, cold spots, and slow heat-up times. The formula begins working within just one hour of circulation, offering a fast and effective solution for blocked or inefficient systems. Compatible with all domestic heating setups - including sealed, open-vented, and combination boilers - LavaTap Sentinel X800 is safe for use with aluminium, copper, steel, and mixed-metal systems. It delivers powerful results either on its own or as part of a full power flush and is suitable for both professional use and DIY maintenance. Each 1-litre bottle treats up to 100 litres of system water - enough for 8 to 10 radiators or equivalent underfloor zones. X800 can be added via radiator, filling loop, or dosing pump. After cleaning, flush the system thoroughly and follow with a corrosion inhibitor such as LavaTap Sentinel X100 for complete protection. Whether you're restoring performance in an older system or preparing a new installation for long-term reliability, LavaTap Sentinel X800 is the smart choice for fast, effective central heating maintenance.
