Over a century ago, Dux hot water systems became a household name in Australia. In the previous three decades, James Hardie Industries, a renowned Australian maker of construction materials, sold Dux to the GWA Group, another Australian company, and is now controlled by the Noritz Corporation, a global manufacturer of residential and commercial hot water heaters. At Moss Vale in the South Highlands of New South Wales, where they have done so for quite some time, Dux manufactures a wide variety of their products.
