What Are Central Heating Inhibitors Used For?



Central heating inhibitors protect your radiators and keep the system running smoothly. After cleaning your system with specialist products to remove limescale and corrosion, use a radiator inhibitor to prevent further build-up.

Using boiler inhibitor products can prolong the life of your system, improve energy efficiency and reduce fuel costs. Applying an inhibitor solution to your system once a year is recommended, as the anti-corrosion and descaling chemicals will break down over time, reducing their effectiveness.
