Dux Ecosmart Pro-Series 270L Heat Pump Hot Water System
The Dux Ecosmart Pro-Series 270L Heat Pump Hot Water System is a high-recovery heat pump designed for larger households wanting efficient stored hot water with strong recovery performance.
With a 270L storage capacity, R290 refrigerant, up to 77 litres per hour heat pump recovery under Dux test conditions, active defrost, touchscreen control and separate hardwired and plug-in variants, the Pro-Series is designed as an energy-efficient alternative to conventional electric storage hot water.
Installed Today offers the Dux Ecosmart Pro-Series 270L as a supply-only heat pump hot water system or with supplied-and-installed options across selected Brisbane and Gold Coast service areas, where available.
What Does the Dux Ecosmart Pro-Series 270L Do?
The Ecosmart Pro-Series uses heat from the surrounding air to heat water stored inside its 270L cylinder.
Instead of relying primarily on direct electric resistance heating, the heat pump refrigeration system captures ambient heat and transfers that energy into the stored water.
The system also includes an electric backup element for very low ambient conditions and boost operation, with the element size depending on whether the hardwired or plug-in model is selected.
Who Is the Dux Ecosmart Pro-Series 270L Best For?
Larger Households
Dux lists the 270L Pro-Series for households of up to 7 people on a continuous tariff, subject to actual hot water demand.
High Hot Water Users
The powerful compressor and published 77 L/hr heat pump recovery can suit homes where recovery speed is an important consideration.
Electric Hot Water Upgrades
The Pro-Series has a similar footprint to many electric water heaters it is designed to replace, although airflow, drainage and service access must still be checked.
Dux Ecosmart Pro-Series 270L Key Details
Dux states the 3.5-hour full-tank figure at 20°C ambient temperature when heating water from 20°C to 60°C. Actual recovery varies with ambient conditions, inlet temperature, settings and household demand.
Is the Dux Ecosmart Pro-Series 270L Right for My Home?
A Good Choice If...
You want a family-sized heat pump with fast recovery, touchscreen scheduling, R290 refrigerant and the choice of hardwired or 10A plug-in configurations.
Consider Another Option If...
Your household has low hot water demand or the property cannot provide suitable airflow, condensate drainage, electrical supply, base support or service access.
Check Before Ordering
Confirm whether you need the hardwired or plug-in model, household demand, dimensions, electrical supply, drainage, water pressure, delivery access and installation location.
How Many People Can the Ecosmart Pro-Series 270L Suit?
Dux lists the Pro-Series 270L for households of up to 7 people on a continuous tariff.
That figure is a sizing guide rather than a guarantee. Actual suitability depends on how much hot water the household uses and how quickly that demand occurs.
- Number of occupants
- Average shower duration
- Shower flow rates
- Number of bathrooms
- Bath usage
- Laundry and kitchen demand
- Timing of hot water demand
- Tariff configuration
- Ambient temperature
- Selected heating schedule
How Does the Dux Ecosmart Pro-Series 270L Work?
1. Heat Is Collected From the Air
The refrigeration circuit absorbs usable heat energy from the surrounding ambient air.
2. Heat Is Transferred to the Tank
The compressor and external wraparound condenser transfer that energy into the stored water.
3. Hot Water Is Stored
The heated water remains stored in the 270L cylinder until it is required throughout the property.
Key Features of the Dux Ecosmart Pro-Series 270L
Fast Heat Pump Recovery
Dux publishes heat pump recovery of up to 77 litres per hour under stated operating conditions.
Touchscreen Controller
A tank-mounted touchscreen provides access to scheduling and operating mode selection.
R290 Refrigerant
The system uses R290 natural refrigerant. Current Dux literature lists its refrigerant GWP as 3.
Wraparound Copper Condenser
The external copper condenser design keeps the condenser separate from direct contact with the stored water and supports use across a broad range of water qualities.
Active Defrost
Active defrost supports heat pump operation in colder climates by managing frost formation around the evaporator.
UV & Flame Resistant Housing
The polymer top housing is designed with UV and flame resistance for durability in Australian outdoor conditions.

Which Dux Ecosmart Pro-Series 270L Model Do I Need?
The Pro-Series is available in two electrical configurations. The heat pump section and 270L storage capacity are shared, but the electric backup element and electrical connection differ.
270DHB36 Hardwired
The hardwired model has a 2.4 kW electric element, listed rated input of 3.48 kW and rated current input of 14.5 A. It requires a compliant hardwired electrical connection.
270DHB36P Plug-In
The plug-in model has a 1.0 kW electric element, listed rated input of 2.1 kW and rated current input of 8.8 A. It is supplied with a 3m power cord for connection to a suitable 10A GPO.
Up to 77 Litres Per Hour Using the Heat Pump
Dux states that the Pro-Series can heat up to 77 litres of hot water per hour solely using heat pump operation under its specified test conditions.
Dux also publishes a full-tank heating time of approximately 3.5 hours at 20°C ambient temperature when heating water from 20°C to 60°C.
These figures are useful for comparing recovery capability, but real-world recovery changes with ambient temperature, incoming water temperature and system operation.
How Efficient Is the Dux Ecosmart Pro-Series 270L?
Dux's current Pro-Series literature states that the system can use up to 75% less energy than a standard electric water heater under its stated AS/NZS 5125.1 test conditions.
Dux also publishes a COP of 4.7 for the Pro-Series under stated test conditions.
Actual electricity use and savings depend on household demand, climate, incoming water temperature, tariff arrangement, operating schedule, electric boost use and the system being replaced.
Scheduling the Pro-Series Around Solar or Tariffs
The Pro-Series includes an intuitive tank-mounted touchscreen controller for scheduling and mode selection.
This allows heating periods to be planned around household routines and can be useful where the property has solar PV or time-of-use electricity pricing.
Scheduling does not directly connect the unit to a solar inverter. It allows the homeowner to select operating times that may better align with available solar generation or lower-cost tariff periods.
What Refrigerant Does the Dux Pro-Series Use?
The Ecosmart Pro-Series 270L uses R290 natural refrigerant with a charge of approximately 680 grams.
Current Dux product literature lists the refrigerant with a GWP of 3.
R290 is flammable, so refrigeration-related work must be performed by appropriately qualified personnel and the system must be installed in accordance with the manufacturer's requirements.
Can the Dux Ecosmart Pro-Series Operate in Cold Weather?
The heat pump has a published ambient operating range of approximately -5°C to +43°C.
Dux includes an active defrost function for colder climates, helping the refrigeration system manage frost formation during low-temperature operation.
The electric element can provide water heating outside the normal heat pump ambient operating range.
What Is Required to Install the Ecosmart Pro-Series 270L?
- Suitable heat pump installation position
- Stable and level supporting base

800 kPa Maximum Inlet
Dux lists a maximum inlet water pressure of 800 kPa.
1000 kPa Relief Valve
The system has a listed relief valve rating of 1000 kPa / 10 kW.
Existing Valves Matter
A replacement installation may require new pressure-control or safety valves where the existing arrangement is unsuitable or non-compliant.
Does the Dux Ecosmart Pro-Series Need a Drain?
Yes. Heat pump operation produces condensate, and the Pro-Series includes a dedicated condensate drain connection.
The installation position must allow condensate and hot water safety-valve discharge to be managed correctly. Additional drainage work may be required where a suitable discharge point is not already available.
Can the Pro-Series 270L Replace an Electric Storage Water Heater?
The Pro-Series is specifically positioned as an efficient alternative to conventional electric storage and has a similar footprint to many electric systems it is designed to replace.
A heat pump conversion is not automatically a direct tank swap because airflow, condensate drainage, electrical requirements and service access also need to be assessed.
Electric Storage Replacement
The 270L capacity and high recovery can suit selected family-sized electric storage replacements.
Changing Technology
Moving to a heat pump introduces airflow, condensate, refrigeration and operating-noise considerations.
Relocating the System
A new installation position can require extra pipework, drainage, electrical work, base preparation and labour.

Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.
A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.
If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.
If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.
Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.
It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
