Dux Hot Water Systems Available
An Established Australian Hot Water Brand
Dux has been an Australian hot-water brand for more than a century and remains strongly associated with residential storage water heaters.
Dux is part of the Noritz Group, combining Australian hot-water development and manufacturing with the broader technical resources of an international water-heating company.
Much of the current larger Proflo electric range and current Ecosmart heat-pump range is manufactured in Australia.
Dux Proflo Electric vs Dux Ecosmart Heat Pump
| Dux Range | Technology | Best Starting Point | Main Considerations |
|---|---|---|---|
| Proflo Electric | Electric resistance storage | Like-for-like electric replacement | Tank size, tariff, element, dimensions and recovery |
| Ecosmart Heat Pump | Air-source heat pump storage | Efficiency-focused electric upgrade | Capacity, airflow, drainage, noise, electrical setup and recovery |
Dux Proflo Electric Hot Water Systems
Dux Proflo is the main conventional electric-storage range currently offered by Installed Today.
Current capacities include 50L, 125L, 160L, 250L, 315L and 400L, giving Dux a strong spread from compact applications through to larger family homes.
Proflo is particularly relevant where a property already has electric storage and the customer wants a straightforward replacement without changing hot-water technology.
Which Dux Proflo Size Should You Choose?
| Capacity | Typical Starting Point | Common Application |
|---|---|---|
| 50L | Around 1 person / low demand | Units, offices, compact applications and small replacements |
| 125L | Smaller households | Units, couples and lower-demand homes |
| 160L | Small households | Townhouses, rentals and modest family demand |
| 250L | Standard family range | Family homes and everyday residential demand |
| 315L | Larger households | Higher stored hot-water demand |
| 400L | Large households | Strong daily and peak hot-water demand |
Household sizing is only a starting point. Shower duration, bathrooms, baths, tariff and element recovery all affect the correct system size.
Dux Proflo 50L Electric Hot Water
The Dux Proflo 50L is the most compact model in the current Installed Today Dux range.
It measures approximately 670mm high and is designed for compact installations such as selected cupboards, laundries, units, offices and other low-demand applications.
Hardwired and selected plug-in configurations are available depending on the exact model.
Dux Proflo for Smaller Households
The 125L and 160L Proflo systems cover the smaller residential storage range above the compact 50L model.
These sizes can suit units, townhouses, smaller families and rental properties where daily demand does not justify a larger 250L+ tank.
If an existing 125L or 160L system frequently runs out, reassess household demand before simply replacing it with the same capacity.
Dux Proflo 250L for Family Homes
The 250L Proflo sits in the core family-size electric-storage category.
It can suit family homes and rental properties where a standard household needs substantially more stored hot water than the smaller 125L and 160L models.
Check household demand, tariff, element configuration and recovery rather than using tank capacity alone.
Dux Proflo for Larger Families and Higher Demand
The 315L and 400L systems provide greater stored capacity for larger households and properties with heavier daily hot-water use.
These systems can be particularly relevant where several showers occur during concentrated morning or evening periods.
Larger is not automatically better. Confirm the household genuinely needs the extra stored capacity before increasing tank size.
Dux Proflo 80L–400L Is Australian Made
Dux currently manufactures its larger Proflo electric-storage systems in Australia.
The Australian-made range includes the common residential sizes above the compact 50L class and uses enamel-lined steel storage technology.
The 50L model differs and is manufactured through a Noritz manufacturing facility overseas.
Dux Ecosmart Heat Pump Hot Water Systems
The current Installed Today Dux heat-pump range includes 200L, Ecosmart Pro 270L and Ecosmart 285L systems.
Heat pumps use electricity to transfer heat from surrounding air into stored water rather than relying solely on direct resistance heating during normal heat-pump operation.
This makes Ecosmart particularly relevant to customers replacing electric storage and wanting to reduce hot-water electricity consumption where the site is suitable.
Dux Ecosmart 200L Heat Pump
The 200L Ecosmart is the smallest Dux heat pump currently listed by Installed Today.
Dux positions the 200L model toward smaller families looking to upgrade from conventional electric storage while keeping the physical footprint relatively manageable.
It can be especially relevant where a larger 270L–285L heat pump would provide unnecessary stored capacity.
Dux Ecosmart Pro 270L Heat Pump
The Dux Ecosmart Pro 270L provides family-size heat-pump storage with R290 refrigerant and strong recovery capability.
The current product is available in hardwired and plug-in model configurations and can suit larger households, electric-storage upgrades and homes using rooftop solar or time-of-use electricity.
Dux lists the model for larger household demand, but actual suitability still depends on shower habits, climate, tariff and recovery needs.
Dux Ecosmart 285L Heat Pump
The 285L Ecosmart sits at the larger end of the current Dux heat-pump range.
Dux designed this model with the same tank diameter as common Proflo 250L and 315L electric-storage systems, which can make it especially relevant when upgrading from those tank sizes.
It is aimed at larger family households wanting strong heat-pump capacity and improved electricity efficiency.
Current Dux Ecosmart Heat Pumps Use R290 Refrigerant
Dux's current-generation Ecosmart heat pumps use R290 refrigerant.
Refrigerant is only one part of heat-pump design. Tank size, recovery, electrical configuration, controls, noise and installation location remain important when choosing between models.
Should You Replace with Proflo or Upgrade to Ecosmart?
Choose Proflo When
A straightforward electric-storage replacement, familiar technology and lower installation complexity are the priority.
Choose Ecosmart When
Lower electricity consumption and heat-pump efficiency are a higher priority and the installation location is suitable.
Compare Total Installation
Heat pumps can need additional planning for airflow, drainage, electrical supply, base work and noise.
Replacing an Existing Dux Hot Water System
If an existing Dux system has supplied enough hot water, its size and technology provide a useful starting point for the replacement.
Check whether the household has changed since the original system was installed before automatically matching the old tank.
- Existing Dux model
- Tank capacity
- Current household size
- Peak shower demand
- Electrical tariff
- Element rating
- Existing valves
- Tank dimensions
- Connection locations
- Installation access
- Drainage
- Reason for replacement
Upgrading a Dux Electric Storage System to Heat Pump
Customers replacing a Dux Proflo can also compare Ecosmart rather than remaining with standard electric storage.
A heat pump is not automatically a direct physical replacement even if the tank capacity is similar.
Check airflow, condensate drainage, electrical requirements, noise, clearances and access before changing technology.
Dux Ecosmart with Rooftop Solar
Heat-pump hot water can be attractive for homes with rooftop solar where operating times can be aligned with periods of stronger solar generation.
The current Ecosmart generation includes connected technology and scheduling features on selected models.
Solar suitability should still be considered alongside household demand and required recovery.
Dux Hot Water Systems for Rental Properties
Proflo electric storage is particularly relevant to rental properties where straightforward replacement and predictable stored capacity are priorities.
Ecosmart may suit owners who want a heat-pump upgrade and have a suitable installation location.
Choose capacity around realistic tenant occupancy and avoid undersizing purely to reduce purchase cost.
Dux Systems Need to Suit the Site as Well as the Household
Electric-storage systems need sufficient space, stable support, drainage and electrical suitability.
Heat pumps additionally need suitable airflow, condensate drainage and consideration of compressor and fan noise.
- Tank dimensions
- Access path
- Electrical supply
- Existing plumbing
- Valve condition
- Drainage
- Base condition
- Service clearance
- Heat-pump airflow
- Heat-pump noise position

Dux Hot Water System FAQs
Straight answers about Dux Proflo electric storage and EcoSmart heat pump hot water systems, household sizing, energy efficiency, installation and choosing the right model.
What are the most popular Dux hot water systems?
Popular Dux electric storage choices include the Dux Proflo 125L for smaller households, the Dux Proflo 250L for family homes and the Dux Proflo 400L for larger households. Dux also offers EcoSmart heat pumps including 200L, 270L Pro and 285L models for households wanting to reduce electricity use compared with conventional electric storage.
Should I choose a Dux Proflo electric system or a Dux EcoSmart heat pump?
Choose a Dux Proflo electric storage system if you want a straightforward replacement for an existing electric storage tank and lower upfront purchase cost is important. Choose a Dux EcoSmart heat pump if reducing hot water energy use is a higher priority and you have a suitable outdoor installation position with airflow, drainage and electrical supply. Heat pumps generally cost more to purchase but use heat from the surrounding air to reduce reliance on direct resistance heating.
What size Dux electric hot water system do I need?
As a practical starting point, the Dux 50L is intended for very light or point-of-use demand, the Dux 125L suits around 1 to 2 people, the Dux 160L suits around 2 to 3 people, the Dux 250L suits around 4 to 5 people, the Dux 315L suits around 6 to 7 people and the Dux 400L is commonly selected for households of around 8 people. Actual sizing also depends on shower length, bath use, tariff, element size, recovery time and when household members use hot water.
Is the Dux Proflo 250L a good hot water system for a family?
Yes. The Dux Proflo 250L is one of the most popular Dux family-size electric storage systems and is currently recommended by Installed Today for around 4 to 5 people. It has a 250L tank, 3.6kW element, full mains-pressure delivery and dual-sided water connections. It is a practical replacement for family homes already using electric storage hot water.
Is the Dux Proflo 400L suitable for a large family?
Yes. The Dux Proflo 400L is the largest Dux electric storage model currently listed by Installed Today and is recommended for around 8 people. Its 400L tank makes it suitable for larger households, multiple bathrooms and homes with heavy morning or evening hot water demand. It is approximately 1705mm high and 705mm wide, so available installation space should be checked before replacing a smaller cylinder.
What is the difference between the Dux EcoSmart 200L, EcoSmart Pro 270L and EcoSmart 285L?
The main difference is stored-water capacity and household demand. The Dux EcoSmart 200L is the smaller option. The Dux EcoSmart Pro 270L is currently recommended for larger households of around 5 people and is designed for strong heat-pump recovery. The Dux EcoSmart 285L provides the largest tank of the three and is intended for larger families and higher daily hot water use.
Is the Dux EcoSmart 285L an energy-efficient heat pump?
Yes. The Dux EcoSmart 285L uses heat-pump technology and R290 refrigerant rather than relying entirely on a conventional electric resistance element. Dux lists a COP of 4.63 under stated test conditions and states the system can use substantially less energy than a standard electric water heater under its stated modelling assumptions. It also includes Eco, Boost and Holiday modes plus Wi-Fi enabled touchscreen control.
Can I replace a Dux electric storage system with a Dux EcoSmart heat pump?
In many cases, yes. A Dux EcoSmart heat pump can be used as an energy-efficient upgrade from a conventional electric storage hot water system. Heat pumps need suitable outdoor airflow, drainage, electrical supply, a compliant base and service access, so the installation is not always a simple like-for-like cylinder swap. The Dux EcoSmart 285L has the same tank diameter as selected Dux Proflo 250L and 315L systems, which can make it a practical comparison for some replacement locations.
Can I buy a Dux hot water system supply only?
Yes. Dux Proflo electric storage systems and Dux EcoSmart heat pumps can be ordered supply only if you already have the appropriate licensed installer arranged. Supply only includes the hot water system but not installation, valve kits, old-system removal, disposal, electrical work, plumbing alterations, drainage changes or other site-specific upgrades unless purchased separately.
Can I buy a Dux hot water system supplied and installed?
Yes. Supplied and installed options are available for selected Dux systems in eligible installation areas. Electric-storage Basic Install is intended for an eligible external, ground-level electric storage replacement in the existing position. Heat-pump Basic Install is intended for an eligible external, ground-level heat-pump installation. Valves, disposal, additional pipework, electrical upgrades, drainage, base work, relocation and difficult access may cost extra where required.
