Dux Heat Pump Hot Water Systems from $3,839
Dux Heat Pump Hot Water Systems
Explore Dux heat pump hot water systems by brand, model family and replacement type. Compare Dux Ecosmart 200L and 285L systems with the 270L Ecosmart Pro-Series, including tank capacity, heating design, electrical connection, controls and replacement compatibility without duplicating the broader heat pump hot water buying guide.
Choosing Within the Dux Heat Pump Range
This collection is specifically for Dux heat pump water heaters. Rather than explaining heat pump technology generally, it helps compare the Dux Ecosmart range by model family, storage capacity, heating design, electrical connection and replacement fit.
The current Dux range includes standard Ecosmart heat pumps in 200L and 285L capacities, plus the higher-recovery Ecosmart Pro-Series in a 270L tank capacity.
Dux Ecosmart vs Ecosmart Pro-Series
Ecosmart 200L
The compact member of the current Ecosmart range, designed around a 200L storage tank and a single-piece heat pump format.
Ecosmart 285L
The larger standard Ecosmart model, providing additional stored capacity while retaining the single-piece Dux heat pump design.
Ecosmart Pro-Series 270L
The Pro-Series uses a 270L tank and is positioned by Dux around stronger heat-pump recovery for larger hot-water demand.
Different Heating Designs
Standard Ecosmart and Pro-Series models use different heat-exchanger arrangements, so model family matters as well as tank litres.
How Do I Identify My Existing Dux Heat Pump?
Start with the Dux data plate and model number. Record the tank capacity, electrical details and product family, then photograph the complete installation including power, pipework, drainage and surrounding clearances.
Older Dux heat pumps can differ from the current Ecosmart range, so the old model name alone should not be used to assume physical interchangeability.
A 270L Pro-Series and a 285L Ecosmart are close in storage capacity but use different heating designs and are not simply the same appliance with a different tank size.
Dux Ecosmart 200L and 285L Heat Pumps
Dux lists the current standard Ecosmart heat pump range in 200L and 285L capacities. These models use Dux's patented dual-wall heating coil immersed in the water and are designed as single-piece systems.
The two capacities allow customers to stay within the same Dux model family while choosing a different level of stored hot-water reserve.
Dux Ecosmart Pro-Series 270L
The Dux Ecosmart Pro-Series is a separate 270L heat pump model family designed around stronger recovery. Dux specifies an external wraparound copper condenser coil rather than the immersed heating-coil arrangement used by the standard Ecosmart range.
That makes the Pro-Series a distinct Dux product choice rather than simply another storage-size variant.
Dux R290 Heat Pump Models
The current Dux Ecosmart and Ecosmart Pro-Series heat pumps use R290 refrigerant. This is a brand-and-model feature worth checking when comparing current Dux products with older Dux heat pump generations.
For replacement selection, the refrigerant type does not replace the need to compare capacity, electrical connection, installation space and model layout.
Dux Plug-In and Hardwired Heat Pumps
Dux lists plug-in and hardwired configurations within the current Ecosmart range. The exact connection type should be confirmed against the selected model rather than assumed from the tank capacity.
When replacing an existing Dux unit, record whether the current system is plugged into a power point or hardwired before selecting the replacement variant.
Dux Ecosmart App and Controller Features
Current Dux Ecosmart models include smart-control functionality. Dux specifies Smart Life app control on its current Ecosmart range, allowing compatible models to be configured and scheduled through the app.
The heat pump also provides local controls, so compare the exact model and controller functions when smart scheduling or solar-PV timing is important.
Immersed Coil vs Wraparound Condenser
One of the more useful brand-specific differences within the Dux range is the heat-exchanger design. Standard Ecosmart 200L and 285L models use Dux's immersed dual-wall heating coil, while the Pro-Series 270L uses an external wraparound copper condenser.
This distinction helps separate the two Dux model families without relying only on capacity or broad heat pump terminology.
Replacing an Older Dux Heat Pump with a New Dux
A Dux-to-Dux replacement can narrow the search, but the current model still needs to suit the installation. Compare storage capacity, overall dimensions, electrical connection, heating-system layout, plumbing, drainage and service clearances.
If the old Dux model belongs to an earlier heat pump generation, do not assume the current Ecosmart footprint or connection arrangement will be identical.
What to Compare Between Dux Heat Pump Models
| Dux feature | Why it matters | What to compare |
|---|---|---|
| Model family | Standard Ecosmart and Pro-Series use different heating designs. | Ecosmart 200L/285L vs Pro-Series 270L. |
| Storage capacity | Determines stored hot-water reserve. | 200L, 270L or 285L depending on the selected Dux family. |
| Heat exchanger | Distinguishes the Dux product architecture. | Immersed dual-wall coil vs external wraparound condenser. |
| Electrical connection | Affects replacement requirements. | Plug-in or hardwired configuration where available. |
| Controls | Current models include different local and connected functions. | App scheduling, local controller and operating modes. |
| Dimensions & layout | Determines physical replacement fit. | Height, diameter, access, pipework, drainage and clearances. |
Choosing Between Dux Ecosmart 200L and 285L
The 200L and 285L models sit within the same standard Ecosmart family but provide different amounts of stored hot water. The 200L is the more compact option, while the 285L provides a larger reserve.
Detailed household sizing should remain on the broader capacity and heat pump sizing pages; this page simply identifies how the two capacities fit within the Dux range.
When to Compare the Dux Pro-Series 270L
The Pro-Series 270L is the Dux model to compare when the customer is specifically looking for the higher-recovery product family rather than simply the largest standard Ecosmart tank.
Its different compressor and condenser arrangement make it a separate model-type decision within the Dux heat pump range.
When to Use the Dux Heat Pump Collection
This collection is for customers who have already narrowed their search to Dux plus heat pump technology. It should answer questions about Dux Ecosmart model families, capacities, controls, connection types and replacement matching.
Broad topics such as generic heat pump running costs, rebates, refrigerant comparisons or heat pump vs electric belong on the main heat pump pages. Here, the topical focus stays on Dux as the brand and heat pump as the product type.
