A Dux hot water heat pump is $3,300 - $3,850 installed in Western Australia before rebates. After Western Australia rebates and federal STCs, most households pay around $2,700-$3,250 out of pocket. Dux has made hot water systems at Moss Vale in New South Wales for decades and is now part of the Noritz group. The Ecosmart DHC range is designed and manufactured in Australia and is on Solar Victoria's locally made list, which is what puts it in the higher Victorian rebate tier.
