What Are the Benefits of Central Heating System Cleaners?



Using a heating system cleaner regularly will help maintain your boiler, removing any limescale or corrosion. Frequent treatments may also help reduce boiler noise which can be a nuisance. Some products can be left in the system whilst others need to be flushed out.

After cleaning, you can use a central heating inhibitor or boiler noise silencer fluid to protect the system from scale and debris build-up for longer. Browse our selection to find effective cleaning products that work through the system quickly.
