It’s intended to be used before adding corrosion inhibitors, helping prepare the system for long-term protection and efficient operation.\u003c\/p\u003e\n\u003ch3 data-start=\"342\" data-end=\"366\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"367\" data-end=\"906\"\u003eDuring installation or servicing of a heating system, contaminants such as soldering flux, metal filings, sealant residues, and rust particles can remain in the system water. These impurities can reduce flow, impair heat transfer, and lead to cold radiator spots or noisy pumps. \u003cstrong data-start=\"646\" data-end=\"660\"\u003eF3 Cleaner\u003c\/strong\u003e works by dispersing these contaminants into the system water so they can be \u003cstrong data-start=\"737\" data-end=\"752\"\u003eflushed out\u003c\/strong\u003e during a system flush. It prepares the heating circuit for the addition of a corrosion inhibitor, improving efficiency and helping extend component life.\u003c\/p\u003e\n\u003ch3 data-start=\"908\" data-end=\"927\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"928\" data-end=\"1193\"\u003eThis cleaner is suitable for use in \u003cstrong data-start=\"964\" data-end=\"998\"\u003esealed central heating systems\u003c\/strong\u003e, including combi, system, and conventional boilers. It is formulated to be compatible with typical heating system metals such as steel, copper, and aluminium when used according to instructions.\u003c\/p\u003e\n\u003ch3 data-start=\"1195\" data-end=\"1213\"\u003eHow It Works\u003c\/h3\u003e\n\u003cp data-start=\"1214\" data-end=\"1662\"\u003eThe 500 ml bottle is added to the system via an appropriate filling point, such as a filling loop or filter connection. The heating system is then run for a period as recommended, allowing the cleaner to circulate and break down debris. After the cleaning period, the system should be thoroughly flushed with clean water to remove suspended contaminants. Once flushed, a corrosion inhibitor should be added to protect the system over the long term.\u003c\/p\u003e\n\u003ch3 data-start=\"1664\" data-end=\"1682\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"1683\" data-end=\"2104\"\u003eUsing \u003cstrong data-start=\"1689\" data-end=\"1710\"\u003eFernox F3 Cleaner\u003c\/strong\u003e helps improve circulation and heat transfer by removing soluble and suspended contaminants early in the system’s life. It reduces the risk of performance issues, prepares the system for effective corrosion protection, and supports quieter, more efficient heating operation. By removing debris before it settles, the product helps prevent future blockages and wear on the boiler and components.\u003c\/p\u003e\n\u003ch3 data-start=\"2106\" data-end=\"2130\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"2131\" data-end=\"2455\"\u003eFernox F3 Cleaner is ideal for \u003cstrong data-start=\"2162\" data-end=\"2199\"\u003enew central heating installations\u003c\/strong\u003e, boiler upgrades, or systems that have been drained and refilled after repair. It’s commonly used as part of pre-commissioning preparation or during servicing to ensure the system is clean before introducing a corrosion inhibitor or long-term conditioner.\u003c\/p\u003e\n\u003ch3 data-start=\"2457\" data-end=\"2473\"\u003eUsage Note\u003c\/h3\u003e\n\u003cp data-start=\"2474\" data-end=\"2679\"\u003eAlways follow the manufacturer’s dosing and safety instructions. After cleaning with F3 and flushing the system, add a suitable inhibitor to ensure lasting protection against corrosion and scale formation.\u003c\/p\u003e","brand":"Fernox","offers":[{"title":"Default Title","offer_id":57056154681689,"sku":"50010240","price":25.64,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9738\/1209\/files\/50010240_FO.jpg?v=1768819987","url":"https:\/\/plumbpartsxpressshop.com\/products\/fernox-f3-cleaner-500ml","provider":"Plumbparts xpress","version":"1.0","type":"link"}
