Keston 28mm System Filter: Features & Benefits

Perfect for larger heating systems, the Keston 28mm System Filter comes with up to seven years warranty. Plus, installing this filter means you can have free commissioning​ on single Keston Heat boilers†.

This appliance is equipped with an ultra-thin sheath that makes it easier to magnetically capture debris, as well as features including a low profile drain valve and rapid-fit connectors that make servicing quick and simple.

How a Magnetic Filter Makes Your Boiler More Efficient

Magnetic system filters help protect your boiler from the debris that can collect over time, including the iron compounds that build up when water runs through your central heating system.

This can have an impact on how efficiently your boiler is able to run, which means it needs to use more energy and work harder to provide the warmth you need. This 28mm magnetic system filter can remove impurities from the water in your central heating system.

By helping your Keston Heat run more efficiently, this handy appliance can save money on your energy bill and help your boiler last longer.
