Sentinel X100 Inhibitor – 1 Litre

Sentinel X100 Inhibitor is a premium system protection treatment specifically suited to modern underfloor heating systems, while also delivering excellent protection for traditional radiator-based central heating.

Underfloor heating systems rely on consistent water flow through multiple pipe circuits, manifolds and blending components. Even small amounts of corrosion debris or limescale can restrict flow, reduce heat output and affect system balance. Sentinel X100 helps prevent these issues by protecting clean systems against internal corrosion and scale formation, ensuring reliable circulation and even heat distribution across every zone.

For installers and homeowners investing in underfloor heating, long-term system cleanliness is critical. Sludge build-up within pipework or manifolds can compromise performance and efficiency, while corrosion can damage pumps, valves and heat exchangers. Sentinel X100’s advanced TripleTech™ anti-corrosion technology actively protects all common system metals, helping to extend component lifespan and maintain design performance.

Recommended by the Energy Saving Trust, X100 supports optimum system efficiency — an important factor in low-temperature heating systems such as underfloor heating, where performance depends on clear heat transfer surfaces and unrestricted flow.

While particularly beneficial for underfloor heating circuits and manifolds, Sentinel X100 is equally suitable for conventional indirect central heating systems with radiators. It prevents cold spots, reduces boiler strain and helps minimise fuel consumption across the entire system.

By limiting hydrogen gas formation caused by corrosion, the inhibitor also helps reduce system noise and air locking — common issues in both radiator and underfloor heating installations.

Whether used during commissioning of a new underfloor heating system or added to an existing clean central heating system, Sentinel X100 provides dependable, long-term protection.
