These days an integral part of any boiler installation is to include a System Filter, as well as a timer controller. in fact, It is now a recommendation of British Standards 7593 that all heating systems should have a filter or inhibitor installed to protect your heating system in the future.
Boiler manufacturers (such as Worcester Bosch, and Vaillant) give extended guarantees if a filter is included. with the installation.
What is System Filter and what does it do?
Basically, it’s a magnet that prevents the debris inside the system from causing potential damage to the boiler and stops it from gathering in your radiators.
Below is a simple diagram showing what happens inside a typical central heating system.
The System Filter is installed on the return pipe close to the boiler so that the debris gets attracted by its giant magnet, becoming attached to it. During the annual boiler service, the filter is opened and the debris is flushed away.
Benefits of a System Filter
- Highly recommended for all types of boilers, especially high-efficiency boilers.
- Unique dual-action – automatically and continuously removes both magnetic and non-magnetic dirt from the heating system.
- Proven to improve energy efficiency by independent testers.
- Helps to reduce running costs.
- Helps to protect and prolong the life of components such as the boiler & radiators.
- Helps to reduce nuisance call-outs by eliminating problems caused by circulating dirt.
- Slim design fits neatly on any pipework.
- Easily cleaned during the heating systems annual service.
- Simple and easy to install.
- Guaranteed for the life of the boiler to a maximum of 20 years.
