Types of Central Heating Additives


Central heating cleaner removes corrosion and scale to improve the efficiency and longevity of both old and new systems. Regular cleaning can also help reduce boiler noise or use boiler silencer fluid after cleaning for longer-lasting results.

Choose a central heating inhibitor to protect newly cleaned systems against corrosion or limescale build-up whilst extending the life of your system and reducing fuel usage. If your boiler is leaking and losing pressure, try a central heating leak sealer to address the problem quickly.
