We recommend using system chemicals to clean and protect your central heating system and your radiators. When your central heating system is serviced annually, it is advised to put a system cleanser in your system and run it through as per the instructions prior to draining down. This will remove any sludge and dirt build up and allow your radiators to perform more efficiently. Read more on how to correctly maintain and bleed your radiators.
