Aptly named, this Dux Gas Storage System really is a prodigy. This is no standard 5-star hot water heater. With its all-new burner technology, insulated tank and unparalleled recovery times, you can shower in uninterrupted hot water. Designed to replace existing recessed gas storage tanks, Dux Prodigy 5 is a cost-effective alternative. With enough hot water for a six-person household, shower times will never be an issue… even with no power!
