Sentinel X100 Inhibitor X100L-12X1L-EXPA

This 1-litre central heating system inhibitor is designed to protect heating circuits from corrosion and limescale build-up. Suitable for use in domestic and light commercial multi-metal systems, it supports ongoing system maintenance following cleaning or flushing.

Installers typically apply the product directly to the heating system via a radiator or designated filling point. It is compatible with various water types, including hard, soft, and artificially softened water, and is intended for regular use to help maintain radiator performance and reduce the risk of blockages or noise.
