“We had problems with our stove and flue since fitted two years ago. It worked fine when burning but we would get downdraft when the system was cold and not being used and even had our carbon monoxide alarm go off when the burner cooled; after a burn because the downdraft would kick in. A Local company fitted a FlueCube and we have seen a huge difference. So I certainly would recommend to anyone in a similar position and we are very pleased with the Cube."
