{"product_id":"worcester-80-125-external-1m-flue-extension","title":"Worcester 80\/125 External 1m Flue Extension","description":"\u003ch3\u003eWorcester 80\/125 External 1m Flue Extension\u003c\/h3\u003e\n\nThe Worcester 80\/125 External 1m Flue Extension is designed to increase the length of an external Worcester balanced flue system by an additional metre. This makes it an ideal component for installations where the standard flue length isn’t sufficient — for example, when the flue needs to clear overhangs, reach higher termination points, or navigate around building features.\n\nBuilt specifically for outdoor use, this extension is manufactured from durable, weather-resistant materials to ensure it withstands long-term exposure to the elements. Its robust construction helps maintain safe and efficient expulsion of combustion gases while ensuring the flue system remains compliant with Worcester Bosch installation standards.\n\nEasy to fit and engineered for secure connections, the 1m external extension provides heating engineers with the flexibility needed to achieve a safe, reliable, and professional flue setup.\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003ch4\u003eIs this 1m extension compatible with all Worcester boilers?\u003c\/h4\u003e\n\nIt is designed for Worcester systems using the 80\/125 balanced flue configuration. Always check your boiler’s manual to confirm compatibility.\n\n\u003ch4\u003eCan multiple external extensions be added together?\u003c\/h4\u003e\n\nYes — but the total flue length and number of bends must stay within Worcester Bosch’s allowable limits. A qualified heating engineer can confirm what’s permitted for your boiler model.\n\n\u003ch4\u003eDoes weather exposure affect the performance of this extension?\u003c\/h4\u003e\n\nNo — the extension is built for outdoor use with materials designed to resist corrosion and weathering, ensuring long-term reliability when installed correctly.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/plumbing-supplies\"\u003eplumbing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/boiler-accessories\"\u003eboiler accessories\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Worcester","offers":[{"title":"Default Title","offer_id":51955205505366,"sku":"144734","price":84.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/worcester-80125-external-1m-flue-extension-8205898.jpg?v=1772639049","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/worcester-80-125-external-1m-flue-extension","provider":"JJ Building Materials","version":"1.0","type":"link"}
