    Hi Will this be okay for a multi fuel stove on a Poujoulat twin walled pipe
    Question by: Amanda George on 5 Aug 2026, 09:18
    Hi Amanda,

    There won't be a problem with a multifuel stove. I would however heavily recommend checking your HETAS-registered fitter regarding a hybrid system including both Poujoulat and Dura Flue branded parts, as this cowl is primarily designed for installation with other Dura Flue components,

    If the fitter checks the dimensions, specifications etc. on this cowl compared to the Poujoulat system and is happy with this then there shouldn't be an issue
