Dux is one of Australia's oldest and most trusted hot water brands, manufacturing here since 1915 with electric tanks built in Queensland and a state of the art facility in regional New South Wales. That is more than a century of local know how behind every unit, which is why so many Sydney homes already run a Dux.

Choose your type
Electric, gas, continuous flow and heat pump Dux
The right choice depends on your energy connection, your space, and how much hot water your household uses at once. Here is how the Dux types compare.
Dux electric hot water system
A Dux electric hot water system heats water in an insulated ProFlo tank using an electric element. It is the simplest and cheapest to install, works anywhere there is power, and suits homes on off peak tariffs or with solar PV. Sizes run from a 25L under sink unit up to 400L for large families, with a 10 year tank warranty on the larger models.
Dux gas hot water system
A Dux gas hot water system uses the Prodigy storage tank and natural gas to recover quickly after a big draw and keep running during a power outage. Gas storage suits homes with an existing gas connection and steady demand. The Prodigy is a 4 star unit that shares the footprint of older 3 star tanks, so it is an easy retrofit in 135L and 170L.
Dux continuous flow hot water system
A Dux continuous flow hot water system heats water only as you use it, so you never run out and you are not paying to keep a tank hot. The 26L Condensing unit is 6.7 star, wall mounted and compact, with a stainless steel secondary heat exchanger and electronic ignition. Available preset to 50 or 60 degrees, natural gas.
Dux heat pump hot water system
A Dux heat pump hot water system pulls warmth from the surrounding air to heat the tank, using roughly a third of the energy of a standard electric unit. Dux builds the Ecosmart heat pump range, and while we do not stock it in the online store yet, we can source, install and service it. A heat pump is often the model that unlocks the biggest rebate, so ask us if it suits your place.

A supply and install quote adds fitting, connection and removal of your old unit. In NSW a tempering valve is a legal requirement on most installs to limit water temperature at the tap, which can add a small parts and labour cost, and we will always tell you up front if your job needs one. If you are moving to an efficient heat pump or solar model, you may be eligible for a discount through the NSW Government hot water upgrade incentive, and you can compare running costs for each type on the Australian Government energy.gov.au hot water guide.

Supply, install and beyond
Dux hot water installation, replacement and repairs
We handle the full job. Dux hot water system installation for a brand new unit, fast Dux hot water system replacement when an old system fails, and straightforward Dux hot water system repair when a fix is the smarter call.
Installation
Licensed Dux hot water system installation for new builds, renovations and upgrades. We size the unit to your home, install to code, and fit the required safety valves so it passes and lasts.
Replacement
When a unit fails you want hot water back today. We carry common Dux electric, gas and continuous flow sizes and can often complete a same day Dux hot water system replacement, taking the old system away with us.
Repairs
Sometimes a repair is worth it. For a Dux hot water system repair we diagnose the fault first, whether it is a worn element, a failed thermostat, a gas ignition issue or a leaking valve, then give you an honest repair or replace call.
All work is carried out by licensed plumbers, which matters for safety, warranty and compliance. You can confirm any tradesperson holds a current licence before they start using the free Service NSW licence check tool. Running a business? We also handle commercial hot water systems across Sydney.
Straight advice
Which Dux is right for your home?
Get the size and type right and a Dux will run quietly in the background for years. Get it wrong and you either run out of hot water or pay to heat water you never use.
Match the size to the household
As a rough guide, a couple is well served by a smaller ProFlo tank or the 26L continuous flow, while a busy family of four or more needs a 315L to 400L tank or the continuous flow. We size it to your real usage, not a guess.
Work with your energy source
Gas connected homes often suit a Prodigy gas storage tank or the 26L continuous flow, while all electric homes suit a ProFlo electric tank or a heat pump, especially with solar. We work with what you already have.
Consider your space
The 26L continuous flow unit is slim and wall mounted for tight spots, while ProFlo and Prodigy storage tanks need floor room. We check access before we recommend anything.
Repair or replace, honestly
If your current unit is young and the fault is minor, a repair may be the smart call. If it is old, leaking or rusted, replacement usually costs less over time. We tell you straight.
Not sure whether to stick with your old unit? An old, failing system quietly costs you in higher bills and cold showers, so it is worth a quick chat before it dies completely. We will give you a straight repair or replace answer for your place.
Answers, straight up
Dux hot water FAQs
Thermann is the house brand of Reece, Australia's largest plumbing supplier, and has been sold here since 2012. The storage tanks are Australian made and the range is supported by Reece nationwide, which makes parts and service easy to get for the life of the unit.
Yes, for most homes they are a solid, well priced choice. The electric tanks use Y class commercial grade enamel and a larger anode for a long service life, the Prodigy gas range is a reliable retrofit, and the 26L continuous flow is a 6.7 star condensing unit. As with any brand, the install matters as much as the unit, which is why we fit them to code.
Supply prices in our store start around $480 for a compact 25L ProFlo electric unit and run to roughly $2,180 for a large 400L twin element tank, with gas storage around $1,288 to $1,488 and the 26L continuous flow at $1,650. A full supply and install price adds fitting, connection, any required valves and removal of the old unit, which we confirm on site before starting.
With normal use and occasional servicing, a Dux electric system typically lasts around 10 to 15 years, a gas system around 8 to 12 years, and a heat pump around 10 to 15 years. Dux backs the larger electric tanks with a 10 year cylinder warranty and the continuous flow with a 12 year heat exchanger warranty. Water quality, usage and maintenance all affect real world lifespan.
It depends on how many people use hot water and when. As a rough guide, a couple suits an 80L to 160L ProFlo tank or the 26L continuous flow, while a family of four or more suits a 250L to 400L tank or the continuous flow. We size it to your actual usage so you neither run out nor overpay.
In NSW a tempering valve is a legal requirement on most hot water installs. It limits the water temperature delivered to bathroom and hand basin outlets to help prevent scalding. If your job needs one, we tell you up front and include it in the quote rather than adding it as a surprise.
Common warning signs are no hot water at all, water that runs out too quickly, rusty or discoloured water, leaks or pooling around the unit, rumbling or knocking noises, and hot water that will not hold a steady temperature. If you notice any of these, it is worth booking a check before it fails completely.
Often yes. We carry common Dux electric, gas and continuous flow sizes, so a straightforward like for like Dux hot water system replacement can frequently be done the same day. Call us with your model and situation and we will tell you honestly what is possible.
