About Dux Continuous Flow

Dux manufactures continuous flow hot water systems in two main categories, condensing and non-condensing.  Both produce hot water on demand instead of wasting energy heating water that will just sit in a tank. The condensing style of system utilises a newer technology to harness the power of exhaust heat generated when water passes through the primary heat exchanger. These systems employ a second heat exchanger to extract more energy from the exhaust heat, meaning that less energy is wasted.

The Dux range of continuous flow condensing hot water systems can achieve up to 96% efficiency, compared with a non-condensing water heater which can only achieve around 84% efficiency. This is why the condensing units have been awarded a 6.7 star energy efficiency rating.

Although the Dux continuous flow condensing range may offer superior energy efficiency, the standard non-condensing models in the Dux continuous flow range are not far behind. These non-condensing units have all been awarded an energy efficiency rating of 6 stars or higher.

The Dux continuous flow condensing range consists of units in two different capacities, capable of producing 26L and 21L per minute respectively, whilst the non-condensing units come in 17L, 21L and 26L models. The decision as to which capacity and style of Dux continuous flow hot water system is best suited to you and your family is best made with the assistance of one of our expert plumbers.
