Dux Condensing Continuous Flow Hot Water Heater

Dux Continuous Flow

The Dux continuous flow water heaters are one of the most compact and efficient water heaters on the Australian market right now.

The Dux continuous flow water heaters are an excellent option for the urban Australian home due to their compact size and energy efficiency. These systems only heat the water that is needed when it is needed. This saves energy by not keeping the tank hot, like in traditional systems. This has earnt the system a 6 star energy rating which means you save money over time and also reduce your household’s carbon footprint.The Dux condensing continuous flow hot water heater is highly efficient with a 6.7 star energy rating. It is available in capacities of:

  • 21 litres/min
  • 26 litres/min

Dux Condensing vs Non-Condensing Continuous Flow

Dux produces two types of continuous flow water heater systems. The main difference is the inclusion of condensing technology which makes the system more energy efficient over time.

The condensing continuous flow water heaters features state of the art condensing technology that boasts over 90% thermal efficiency through capturing additional heat in a secondary exchanger. This innovative technology can save over $1000 on your power bill over a 12 year period.

The non-condensing option, however, is a smaller and easier to install system that makes a great affordable water heating solution. 

At Jim’s Plumbing, we have over 15 years of experience repairing, servicing and even installing both types of Dux continuous flow water heaters. So, whether you have an emergency or need advice on installing a system, give us a call.

How does the Dux Condensing continuous flow hot water heater work?

In a non-condensing continuous flow hot water heater energy from the exhaust gas is wasted as it passes through only one heat exchanger situated inside the unit. With a Dux condensing continuous flow hot water heater this (what would have been) wasted exhaust gas is used to heat the water a second time through the use of a secondary heat exchanger. Greatly lowering the exhaust gas temperature and wastage and providing you with huge savings on your energy bills from the extreme efficiency of the unit.

For added peace of mind you can trust the quality, reliability and performance of the Dux condensing continuous flow system as it is backed by a huge 12 year warranty on the heat exchanger and 3 years warranty on full parts and labour*.
