Magnetic / Cyclonic Filters
Installing a filter onto your central heating system can save £££s in increased efficiency of your system, but also save the wear and tear on your boiler by having clean central heating water circulate through it.
The easy analogy here is: You wouldn't expect a car engine to perform well or last long if the oil running through it was dirty and not maintained. It is the same with the boiler, but also other components, such as pumps, valves, etc.
So what makes a system dirty? Essentially, it is mainly the radiators rusting from the inside out. The black dirt you get on a tissue when bleeding your radiators is that rust - known as magnetite sludge. This black sludge builds up on internal components (including inside the boiler) and causes premature wear and tear, and ultimately, failure of expensive components.

It is not just the rust though; for vented systems, with the small water tank in the attic, it is also microbial growth from there:
So what does a magnetic / cyclonic filter do? The filter comprises a magnet which attracts all the magnetite sludge, trapping it in the filter (which is cleaned out on annual boiler servicing), but also traps all the non-magnetic dirt by the cyclonic action of the water passing through the filter. Examples below show the sludge captured, all of which is now not settling on internal components and wearing them out prematurely:
So where does the magnetic filter go? Every system configuration is different, but there are multiple options, some of which are shown here: (Note, that there are various shapes, sizes and brands too).
For heavily contaminated systems, a PowerFlush is recommended to clean the system out, and then the filter is used to keep the system clean as a proactive maintenance measure. For systems that are not heavily contaminated, the filter ensures the boiler and external components are kept clean, capturing any particles in suspension as they pass through the filter.
