Heating Filters

Types of Heating Filters:

Magnetic Filters: Use strong magnets to trap metal particles (iron oxide/sludge). Most common type.

Hydronic System Filters: Combine magnetic and non-magnetic filtration to capture a wider range of debris.

In-line Strainers: Capture larger particles in older or open-vented systems.

About us

What Are Heating Filters in Boilers?

Heating filters, often referred to as magnetic or system filters, are devices fitted to central heating systems to capture sludge, rust, and debris that build up over time.

These unwanted particles — mainly caused by corrosion inside radiators and steel pipework — can reduce efficiency, damage boiler components, and lead to costly repairs.

Installed on the return flow to the boiler, heating filters act as a line of defence, preventing contaminants from reaching sensitive parts like the pump and heat exchanger.

We stock top-performing filters from brands like Adey MagnaClean, Fernox TF1, and Sentinel Eliminator — trusted by professionals for durability, easy servicing, and reliable protection.
