<p>I first introduced you to in-line magnetic filters for central heating systems in my bestof blog article ‘<a title="Read Blog Article - magnetic filters" href="http://www.thebestof.co.uk/local/hinckley/blog/heating-systems-use-of-magnetic-filters/article018039.htm " target="_blank"><strong><span style="COLOR: #ff6600">Heating Systems – use of magnetic filters’ on the 10th March 2010</span></strong></a><strong><span style="COLOR: #ff6600">.</span></strong>  Since then I have received a number of queries following that article about these filters.  It would appear that many of you would like to have a clearer understanding of what they do and how they work.  So let’s see if we can help in this article with the aid of a few diagrams below, courtesy of my preferred supplier <strong>FERNOX</strong>.</p> <p>The <strong>FERNOX in-line filter</strong> is one of the fastest and simplest filters to both install and clean once it has been installed.  The patented technology of this in-line filter harnesses the combined effects of hydro-cyclonic action (think Dyson vacuum cleaners) coupled with a simple magnet!  The result is <strong>an exceptionally efficient filter that will remove both magnetic (metal particles) and non-magnetic particles (sludge)</strong> from your central heating system.</p> <p>Cleaning the in-line magnetic filter just couldn't be simpler; the filter assembly is isolated using the valve fittings and then the magnet can be removed and cleaned with no mess or fuss in seconds.  Solid non-magnetic particles caught in the trap through the hydro-cyclonic action can then be removed with equal simplicity from the lower drain valve.</p> <p>Fitting the in-line filter is also made simple since it is compatible with both horizontal and vertical pipe work meaning that the unit can be kept close to the wall.</p> <p>My article of the 10th March outlined the main benefits of fitting such a filter when installing a new boiler, which are:</p> <ul> <li>the removal of metallic particles and iron oxide sludge deposits not removed by power flushing before installation</li> <li>prolonging the life of the boiler and associated controls, pump and zone valves by capturing any remaining or new debris in the system</li> <li>improving the general efficiency of the boiler and as such aiding energy conservation.</li> </ul> <p>Although, fitting an in-line magnetic filter is not exclusive to just new boilers, they can also be fitted to and benefit existing central heating systems.</p> <p>The diagrams below should help you to appreciate the simplicity of this excellent device but if you need further information on the in-line magnetic filters or help and guidance with any other plumbing or gas installation matter then do please contact me <strong>Roy Lee on 01455 268 676</strong>.</p> <p>If you require further details about <strong><em>Roy Lee Plumbing & Heating</em></strong> then please <a title="Roy Lee Plumbing & Heating feature on the bestof Hinckley" href="http://www.thebestof.co.uk/local/hinckley/business-guide/feature/roy-lee-plumbing-heating/73570" target="_blank"><span style="COLOR: #ff6600"><strong>visit our feature on the bestofhinckley</strong></span></a>.</p>/b11c2bd8-a8da-4895-8299-42fa6e015080.jpg/9e495ab3-d58f-40c6-a443-54fc33f293bc.jpg
