Customers often contact us with downdraught and draw problems in twin wall flue systems that are simply too short. 3m-5m of twin wall flue is prone to a variety of performance issues and ideally should be extended in height. Extending a twin wall flue can prove very expensive as supports may need to be constructed and good quality insulated flue does not come cheap. The alternative may well be to fit a Windkat instead. Many of our customers have been saved the expense of extending their flue by the simple effective addition of a Windkat. With the shortest flues it may be necessary to increase the height of the flue a little (e.g. 0.5m) as well as adding the Windkat but additional flue pipe can be added retrospectively.
