Magnetic boiler filters are devices fitted to central heating systems to capture metallic debris (mainly iron oxide, or “sludge”) that naturally builds up over time. This sludge comes from corrosion inside radiators and pipes and, if left unchecked, can reduce system efficiency, damage boiler components, and cause costly breakdowns.
The filter uses a strong magnet to attract and trap these metallic particles as water circulates through the system — keeping your boiler clean and running efficiently.
Protect Your Boiler: Prevents sludge from reaching sensitive components like pumps and heat exchangers.
Improves Efficiency: A clean system heats up faster and uses less energy.
Reduces Repairs & Call-Outs: Helps avoid system blockages and extends the life of your boiler.
Energy Saving: Lower energy use means lower heating bills and a smaller carbon footprint.
Easy Maintenance: Most filters are simple to service during annual boiler checks.
At Mirage Heating & Plumbing, we stock a full range of magnetic boiler filters to suit different system sizes and setups — perfect for new installs or retrofits. Protect your boiler, improve performance, and keep systems running at their best with a filter you can rely on.

Family run and they know their stuff. The AFC Wimbledon sponsor is a benefit too! samaiar2023-11-15Trustindex verifies that the original source of the review is Google. Good, knowledgeable merchants with a lot of boiler parts in stock which a lot of places don't do. Also open longer than the other boiler spares shops on a Saturday which is a plus!
