Keston 1.25" System Filter: Features & Benefits

The Keston 1.25" System Filter has been specifically designed for the Keston Heat 2 single boiler installations on larger heating systems.

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 1.25" magnetic system filter can remove impurities from the water in your central heating system.

By helping your Keston Heat 2 run more efficiently, this handy appliance can save money on your energy bill and help your boiler last longer.
