Common questions Stainesai
A magnetic filter is a device installed in a heating system to capture and remove debris and sludge, improving efficiency and extending boiler lifespan.
Magnetic filter installation is not classified as gas work in itself. However, if the installation involves working on a gas boiler — such as isolating, draining, or reconnecting it — that element of the work should be carried out by a Gas Safe registered engineer. Always confirm the scope of work before work begins.
A magnetic filter improves heating system performance by preventing blockages and reducing wear on components, leading to more efficient operation.
The cost can vary based on system complexity, accessibility, and any additional plumbing work required.
A magnetic filter should be checked and cleaned annually during a boiler service to ensure optimal performance. Always confirm with your tradesperson before work begins.
Any engineer carrying out gas work in the UK must be registered with the Gas Safe Register. You should always ask to see the engineer's Gas Safe ID card and verify their registration before any gas work is undertaken.
