It captures and retains magnetic and non-magnetic debris—including sludge, rust, and scale—before these particles can circulate through the boiler, radiators, and heat exchanger, helping improve efficiency and reduce breakdown risk.\u003c\/p\u003e\n\u003ch3 data-start=\"390\" data-end=\"414\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"415\" data-end=\"950\"\u003eThis filter is installed in the \u003cstrong data-start=\"447\" data-end=\"465\"\u003e22 mm pipework\u003c\/strong\u003e of a central heating system, typically on the \u003cstrong data-start=\"512\" data-end=\"530\"\u003eflow or return\u003c\/strong\u003e side near the boiler or pump. As water passes through the filter, powerful internal magnets attract and hold metallic debris, while internal chambering and mesh trap non-magnetic particles. Regular filtration helps prevent blockages, cold spots on radiators, noisy pumps, and reduced heat transfer efficiency. Periodically draining or backflushing the filter removes the captured debris, maintaining system cleanliness.\u003c\/p\u003e\n\u003ch3 data-start=\"952\" data-end=\"971\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"972\" data-end=\"1338\"\u003eThe TF1 Sigma HP Filter is sized for \u003cstrong data-start=\"1009\" data-end=\"1027\"\u003e22 mm pipework\u003c\/strong\u003e, making it suitable for many domestic and light commercial heating circuits. It is compatible with most combi, system, and conventional boiler installations that use this pipe diameter. The filter integrates with standard line sizes and joins using the appropriate connectors supplied or recommended by Fernox.\u003c\/p\u003e\n\u003ch3 data-start=\"1340\" data-end=\"1368\"\u003eDesign \u0026amp; Build Quality\u003c\/h3\u003e\n\u003cp data-start=\"1369\" data-end=\"1680\"\u003eFernox engineered the Sigma HP with a robust body and internal magnetic assembly designed for long-term durability. The filter housing and chamber components are made from corrosion-resistant materials, and the design facilitates easy servicing and debris removal without disconnecting the unit from the system.\u003c\/p\u003e\n\u003ch3 data-start=\"1682\" data-end=\"1700\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1701\" data-end=\"2126\"\u003eThis filter helps improve boiler and radiator efficiency by removing harmful debris before it can cause blockages or wear. Cleaner system water supports better circulation, quieter pump operation, and more consistent heat distribution. By reducing sludge and scale build-up, the TF1 Sigma HP Filter can also help extend the life of boiler components and reduce the frequency of service calls related to debris-induced faults.\u003c\/p\u003e\n\u003ch3 data-start=\"2128\" data-end=\"2152\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"2153\" data-end=\"2554\"\u003eThe Fernox TF1 Sigma HP Filter 22 mm is ideal for central heating systems with \u003cstrong data-start=\"2232\" data-end=\"2250\"\u003e22 mm pipework\u003c\/strong\u003e, including domestic homes and smaller commercial properties. It’s particularly beneficial when installed in systems that have shown signs of sludge or debris build-up, during boiler upgrades, or as part of preventative maintenance to enhance efficiency, reliability, and longevity of the heating system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Fernox","offers":[{"title":"Default Title","offer_id":57056155107673,"sku":"50010338","price":106.26,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9738\/1209\/files\/50010338_FO.jpg?v=1768816872","url":"https:\/\/plumbpartsxpressshop.com\/products\/fernox-tf1-sigma-hp-filter-22mm","provider":"Plumbparts xpress","version":"1.0","type":"link"}
