LavaTap Sentinel X100 & X800 Bundle – Central Heating Cleaner and Inhibitor Set – Sludge Remover, Radiator Flush, Rust Prevention, pH Neutral, Treats 100 litres, Heating System Maintenance

• Two-Step Heating System Treatment: Includes one bottle of X800 central heating cleaner and one bottle of X100 radiator inhibitor fluid – a complete solution to flush sludge, then protect against rust and corrosion in all domestic heating systems
• Rapid Sludge and Magnetite Removal: X800 central heating cleaner starts breaking down sludge, rust and magnetite in just 1 hour – ideal for blocked radiator fix, cold spots, poor circulation and noisy boilers without needing a full power flush
• Long-Term Corrosion and Limescale Protection: X100 is a pH neutral, non toxic radiator inhibitor fluid that helps prevent corrosion, scale and internal rust buildup – ideal for ongoing system protection and cleaner, more efficient water flow
• Lower Energy Bills and Fuel Waste: A cleaned and protected heating system transfers heat more effectively, helping radiators warm up faster and reducing gas use – improving boiler performance and cutting long-term energy costs for your home
• Treats Up to 100 Litres of System Water: Each 1L bottle treats 100 litres of water – suitable for homes with up to 10 radiators or equivalent underfloor heating zones, with clear dosing instructions for filling loops, radiators or dosing pumps
• Safe for All System Types and Materials: Compatible with sealed, open-vented and combi boilers and suitable for copper, steel, aluminium and mixed-metal pipework – trusted by heating engineers and DIY users for long-term system maintenance

The LavaTap Sentinel X100 & X800 bundle is a two-part treatment solution for maintaining and protecting your central heating system. This kit includes one 1-litre bottle of X800 central heating cleaner and one 1-litre bottle of X100 central heating inhibitor – together designed to treat up to 100 litres of system water, suitable for homes with up to 10 radiators or equivalent underfloor heating zones. Begin with LavaTap X800, a fast-acting sludge remover and radiator flush that works within one hour of circulation. It breaks down internal build-up including sludge, rust, magnetite, and scale. Ideal for blocked radiator fix, X800 helps restore flow, eliminate cold spots, and reduce boiler noise – making it a powerful alternative to full power flushing. It’s compatible with all heating systems, including sealed, open-vented, and combi boilers. Follow with LavaTap X100, a pH neutral and non toxic radiator inhibitor fluid that protects against corrosion, limescale, and internal rust formation. This central heating inhibitor is suitable for ongoing maintenance and helps extend the life of radiators, pipework, and boilers by maintaining clean, stable water chemistry. It's compatible with all common metals including copper, aluminium, steel, and mixed-metal systems. Used together, X800 and X100 form a complete heating system maintenance routine – clean first, then protect. Apply X800 via a radiator or filling loop and flush thoroughly before dosing with X100. Check inhibitor levels annually and re-dose every five years for optimal performance. Trusted by both heating engineers and DIY users, this bundle supports better energy efficiency, reduced gas waste, and more consistent heating throughout your home.
