Shop Dux hot water systems online with Installed Today for electric storage, gas storage, heat pump and selected gas continuous flow hot water options. Dux is a well-known Australian hot water brand, commonly compared by customers replacing an existing storage tank, upgrading from an older electric or gas system, or choosing a practical hot water solution for homes, townhouses, rentals and renovations.

Dux hot water systems are often chosen for straightforward replacement jobs where the customer wants a familiar brand, a practical storage-style system, or a hot water unit that suits an existing installation location. Depending on the product range, Dux options may include compact electric units, family-sized electric storage systems, gas storage systems, heat pump systems and selected gas continuous flow models.

Installed Today makes it easier to compare Dux hot water systems online by system type, tank size, gas type, household demand, installation location and replacement suitability. Choose supply only if you already have your own licensed installer arranged, or select supplied and installed options where available in eligible Brisbane and Gold Coast service areas.

Supply Only Dux Hot Water Systems Across Australian Metro Areas

Supply-only Dux hot water systems are ideal if you already have your own licensed plumber, electrician or gas fitter arranged. This option suits homeowners, builders, renovators, property managers, landlords and trade customers who need the product supplied without installation included.

The product price is for the Dux hot water system only. Installation, valves, old unit removal, disposal, electrical work, gas work, pipework changes, drainage work, tempering valves, access upgrades and compliance upgrades are not included unless selected separately or shown as part of the chosen option.

Before ordering supply only, check that the selected Dux system suits your property, household size, existing setup, energy source, installation location, access, connection positions and installation requirements.

Supplied and Installed Dux Hot Water Systems in Brisbane and Gold Coast

Supplied and installed options may be available on selected Dux hot water systems in eligible Brisbane and Gold Coast service areas. This option is useful when you want the Dux system and installation arranged together instead of buying the unit separately.

Installation availability depends on the selected Dux product, property location, existing system, access, plumbing setup, gas type, electrical requirements, drainage, valve condition and any additional work required.

Some replacements may need additional valves, disposal, electrical work, gas upgrades, pipework changes, drainage changes, base work or compliance upgrades. These are not included unless selected separately or shown as part of the chosen option.

Dux Electric Hot Water Systems

Dux electric hot water systems are commonly used for storage hot water replacement in homes, apartments, townhouses, rental properties and renovation projects. They are often compared by customers who already have an electric storage tank and want a practical like-for-like replacement.

Electric storage systems heat and store water inside a tank, giving the home a ready supply of hot water for showers, taps, kitchens and laundries. The right Dux electric size depends on household demand, number of people, number of bathrooms, shower habits, bath use, laundry use and whether the existing system has been keeping up.

Smaller Dux electric hot water systems may suit units, granny flats, offices, compact homes and low-use applications. Medium and larger Dux electric systems may suit family homes, rentals, townhouses and properties with higher daily hot water demand.

Dux Proflo Electric Hot Water

Dux Proflo electric hot water systems are commonly compared for standard electric storage replacement. They can suit customers looking for a practical electric hot water tank in common residential sizes.

A Dux Proflo style system may be suitable where the home already has electric storage hot water, the installation location suits a tank-style replacement, and the customer wants a straightforward product pathway without changing to gas, heat pump or instant hot water.

When comparing Dux Proflo electric systems, check tank size, dimensions, element rating, connection positions, installation location, household demand and whether the existing electrical setup suits the selected model.

Dux Gas Storage Hot Water Systems

Dux gas storage hot water systems are commonly chosen by customers replacing an existing natural gas or LPG storage-style hot water unit. These systems heat and store water in a tank, giving the household a ready supply of hot water for everyday use.

Gas storage may suit homes where the existing gas storage setup has worked well and the customer wants to stay with a familiar tank-style system. It can be a practical option for family homes, rental properties, townhouses and customers wanting a gas hot water replacement without changing to continuous flow.

Before ordering a Dux gas storage system, check the gas type carefully. Natural gas and LPG models are different and must match the property. Also check the current tank size, installation location, connection positions, ventilation, access and whether the selected Dux model is a practical replacement for the existing unit.

Dux Heat Pump Hot Water Systems

Dux heat pump hot water systems are commonly compared by customers wanting a more efficient electric hot water option than standard electric storage. A heat pump uses heat from the surrounding air to help heat stored water, so installation location and airflow are important.

A Dux heat pump may suit customers replacing an old electric storage tank, upgrading during a renovation, improving hot water efficiency, or choosing a modern electric hot water system where the site is suitable.

Heat pumps need more planning than standard electric tanks. Before ordering, check the outdoor location, airflow clearances, drainage, electrical requirements, noise position, access, tank size and whether the system suits the household’s daily hot water demand.

Dux Continuous Flow Gas Hot Water

Selected Dux gas continuous flow hot water systems may suit customers wanting a compact wall-mounted gas hot water option. Continuous flow systems heat water as it passes through the unit instead of storing hot water in a tank.

A continuous flow gas system may suit homes already using natural gas or LPG where the gas supply, water pressure and installation location are suitable. These systems are usually compared by flow rate rather than tank capacity.

Changing from gas storage to continuous flow may require gas pipework changes, wall mounting, plumbing changes, electrical work, drainage changes, valve upgrades or compliance work. These extras are not included unless selected separately or shown as part of the chosen option.

Natural Gas and LPG Dux Systems

Dux gas hot water systems may be available in natural gas and LPG versions depending on the model range and stock availability. The correct gas type must be selected before ordering.

Natural gas systems are designed for properties connected to a natural gas supply. LPG systems are designed for properties using bottled LPG.

Natural gas and LPG hot water systems are not interchangeable. Ordering the wrong gas type can delay installation and may require product exchange or additional work. If you are unsure, check the label on the existing hot water system or confirm with your licensed gas fitter before ordering.

Choosing the Right Dux Hot Water System Size

Choosing the right Dux system starts with the way the home uses hot water. A system that is too small may run short during peak use, while a system that is too large may cost more than needed and may not suit the installation location.

Smaller Dux storage systems may suit compact homes, units, granny flats, offices and low-demand applications.

Medium Dux systems may suit couples, townhouses, small families, rental properties and everyday replacement jobs where the existing tank size has worked well.

Larger Dux systems may suit family homes, homes with multiple bathrooms, bath use, higher laundry demand and households with heavier morning or evening hot water use.

Heat pump systems should be compared by tank size, recovery, installation location and household demand. Continuous flow gas systems should be compared by flow rate, gas type, water pressure, number of bathrooms and expected outlet use.

Replacing an Existing Dux Hot Water System

Replacing an existing Dux hot water system can often be simpler than changing to a completely different system type, especially if the current unit has performed well and the household’s hot water demand has not changed.

Before choosing a replacement, check the old Dux model, tank size, energy source, gas type if applicable, installation location, connection positions, electrical supply, valve condition, base condition and access.

If the current Dux system is electric storage, another electric storage system or a heat pump may be worth comparing. If the current system is gas storage, matching the gas type and storage style is important. If the current system is continuous flow gas, the gas type and flow rate should be checked carefully.

A replacement is also a good time to check whether the household has changed. More occupants, extra bathrooms, renovations, tenants or heavier water use may mean the old system size is no longer the best fit.

Dux for Rental Properties

Dux hot water systems are commonly compared for rental properties because landlords and property managers often want practical, recognisable and serviceable replacement options.

For rentals, the best Dux system is usually one that suits the expected number of occupants, existing energy source, installation location and ongoing maintenance requirements.

Electric storage may suit many standard rental properties where the home is already set up for electric hot water. Gas storage may suit properties already using natural gas or LPG storage. Heat pump systems may suit rentals where the owner wants a more efficient electric option and the site is suitable.

When choosing a Dux system for a rental, avoid undersizing. A system that is too small can create tenant complaints and may not suit the expected daily demand of the property.

Dux for Family Homes

Family homes often need more careful hot water sizing because demand can be higher during morning and evening peak periods. Multiple showers, baths, laundry use, kitchen use and back-to-back hot water demand can quickly test an undersized system.

Dux electric storage, gas storage, heat pump and selected continuous flow gas systems can all suit family homes depending on the property setup.

For electric storage, larger tanks are often compared for family use. For heat pumps, tank size, recovery and location matter. For gas storage, capacity and gas type need to match the home. For continuous flow gas, the flow rate and gas supply must support the expected number of outlets.

The right Dux system depends on the home, not just the number of people. Bathroom count, shower habits, bath use, water pressure, energy source and installation location all matter.

Dux for Renovations and Upgrades

Renovations are a good time to review whether the existing hot water system still suits the home. Adding bathrooms, upgrading showers, adding a bath, changing laundry use or increasing household occupancy can all affect hot water demand.

A renovation may also create an opportunity to upgrade from electric storage to heat pump, change from gas storage to continuous flow, relocate the system, or choose a larger size that better suits the new layout.

Before ordering a Dux system for a renovation, check the final fixture count, expected household demand, available space, energy source, drainage, access and whether extra plumbing, gas or electrical work will be required.

Dux Electric Storage vs Dux Heat Pump

A Dux electric storage system is usually the simpler replacement where the home already has a standard electric hot water tank and the customer wants a familiar storage-style option.

A Dux heat pump may be worth comparing where the customer wants a more efficient electric hot water option and the installation location is suitable.

The trade-off is that heat pumps need more space, airflow, drainage and site planning. They may cost more upfront but can be a strong option for homes where energy efficiency is a priority.

The right choice depends on budget, available space, electricity setup, household demand, outdoor location and whether the customer wants the simplest replacement or a more efficient upgrade.

Dux Gas Storage vs Instant Gas

Dux gas storage systems heat and store water in a tank. They can be a practical replacement where the property already has gas storage and the current setup has worked well.

Instant gas or continuous flow systems heat water as it passes through the unit. They are usually wall-mounted and compared by flow rate rather than tank size.

Gas storage may suit customers wanting a familiar like-for-like replacement. Instant gas may suit customers wanting a compact external system and continuous flow performance where the gas supply and water pressure are suitable.

Changing from gas storage to instant gas may require extra plumbing, gas and electrical work, so the full installation requirements should be considered before ordering.

Installation Location and Access

Dux hot water systems need to suit the installation location. Electric and gas storage systems need enough space, a stable base, safe access and suitable plumbing connections. Heat pumps need outdoor space, airflow, drainage and noise consideration. Gas continuous flow systems need compliant external wall mounting, gas supply, water connections and electrical access where required.

Before ordering, check:

Existing system location

Access path

Tank size and dimensions

Gas type if applicable

Electrical supply

Water connections

Drainage

Base condition

Valve condition

Clearances

Outdoor exposure

Service access

Whether the old system can be removed safely

A system that suits the household still needs to suit the site.

Dux Supply Only or Installed Options

Supply only is best when you already have your own licensed installer arranged and only need the Dux system supplied.

Supplied and installed options may suit customers who want the product and installation arranged together where the selected Dux product and location are eligible.

For supply-only orders, your own installer should confirm the system is suitable before installation. For supplied and installed options, final suitability can depend on product availability, address, access, current system, valves, disposal, gas, electrical, pipework, drainage and compliance requirements.

Choosing the Right Dux System Online

Choosing the right Dux hot water system online is easier when you start with the current system.

If you have electric storage, compare Dux electric storage and Dux heat pump options.

If you have gas storage, compare Dux gas storage systems in the correct gas type.

If you have continuous flow gas, compare gas type, flow rate and installation requirements.

If the home is being renovated or the household has changed, compare the replacement based on future demand rather than only the old unit size.

The best Dux system is the one that suits the property, energy source, household demand, installation location and budget.
