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.

Honest pricing

Dux Hot Water System Prices in Sydney

The Dux hot water system prices below are the supply only figures from our store. Your final Dux hot water system price for a full supply and install job depends on your existing setup, which we confirm before we start, never as a surprise at the end.

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.
