Worcester 80/125 External 1m Flue Extension

Worcester 80/125 External 1m Flue Extension

The Worcester 80/125 External 1m Flue Extension is an important fitting for creating a safe and compliant boiler installation, helping remove combustion gases from the appliance to outside air. It is a useful choice when replacing or specifying essential boiler parts for a compatible heating setup. As part of our wider boiler accessories range, this product helps installers complete the system neatly and reliably.

The 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. Built 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. Easy 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.

FAQs

Is this 1m extension compatible with all Worcester boilers?

It is designed for Worcester systems using the 80/125 balanced flue configuration. Always check your boiler's manual to confirm compatibility.

Can multiple external extensions be added together?

Yes - 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.

Does weather exposure affect the performance of this extension?

No - the extension is built for outdoor use with materials designed to resist corrosion and weathering, ensuring long-term reliability when installed correctly.
