“I have had a Aga for 6 years that has smoked every time we have windy conditions. I have fitted 4 different cowls, all supposed to stop the downdraft, but all with no success. I recently fitted a FlueCube and this has fully solved the problem, even in the highest gales. On the day I fitted the Flue cube the Aga was smoking bad but immediately the Fluecube was fitted all smoke and smell ceased. This has been a terrific investment and a reduction in fuel use is quite measurable. Thank you for finally solving my problem.”
