Limescale and corrosion are the two main causes of central heating inefficiency, leading to radiator cold spots, boiler inefficiency, a noisy system and a multitude of other problems.

Once a system has been prepared using one of the cleaners from the Sentinel cleaning range, it should be protected with Sentinel X100 Inhibitor to prevent the occurrence of limescale build up or corrosion.

Sentinel X100 Inhibitor has TripleTech™ Anti-Corrosion Technology, a unique blend of heavy-duty specialist corrosion inhibitors.

Since central heating systems are normally made up of a variety of metals, each of these specialist inhibitors provides protection for different metals for unrivalled performance in protecting multi-metal central heating systems.

1 litre of Sentinel X100 Inhibitor is sufficient to treat a typical domestic system of up to 10 radiators. Larger systems should be dosed with twice this amount.
