FAQs - Do I have a central heating system filter?

Do I have a central heating system filter?

• If you have a central heating filter fitted, it may be fitted above the boiler, below the boiler or maybe even in the airing cupboard.
• The central heating filter keeps your system clean and prevents sludge build-up, meaning that your boiler will work efficiently for many years.
