PREMIUM 3 PHASE INSTANT ELECTRIC HOT WATER
Stiebel Eltron DHE 27 AU Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs the Stiebel Eltron DHE 27 AU premium three-phase electric instantaneous water heater across eligible Brisbane, Gold Coast and surrounding South East Queensland service areas.
The DHE 27 AU is Stiebel Eltron's premium high-output continuous-flow electric platform. Instead of storing a large cylinder of hot water, it heats water as it passes through the appliance and uses advanced electronic control to manage outlet temperature and available flow.
At 415V, the DHE 27 AU is rated at 28kW and approximately 38.9A per phase, with manufacturer-specified 40A protection. It combines Stiebel Eltron's 4i Technology, electronic flow-rate control, an illuminated multifunction display, temperature memories and ECO functions with a compact 466 × 225 × 116mm wall-mounted body.
Stiebel Eltron DHE 27 AU at a glance: article 202659 is a premium three-phase instantaneous electric water heater with 28kW output at 415V, approximately 38.9A rated current per phase, 20–60°C temperature selection and a 2.5L/min switch-on flow. Current Stiebel Eltron data lists approximately 14.3L/min at a 28°C temperature rise and 8.0L/min at a 50°C rise at 415V. It can serve one or several outlets where the electrical supply and hot water demand are appropriately sized.
PRODUCT AT A GLANCE
Stiebel Eltron DHE 27 AU Premium Continuous Flow
28kW at 415V
High-output three-phase instantaneous electric heating for suitably sized residential and commercial applications.
4i Technology
Multiple electronic sensors and fully electronic control regulate heating and flow to help maintain the selected outlet temperature.
20–60°C Control
Precise user-adjustable outlet temperature through the illuminated multifunction display.
Multi-Point Capability
Stiebel Eltron specifies the DHE for one or several draw-off points where combined demand remains within its available capacity.
PREMIUM DHE TECHNOLOGY
What Makes the DHE 27 AU Different?
The DHE sits above simpler electronically controlled instantaneous systems by combining temperature regulation with electronic flow-rate control. When demand exceeds what the heating output can support at the selected temperature, the appliance can manage flow rather than simply allowing outlet temperature to fall uncontrolled.
4i Electronic Control
Stiebel Eltron uses multiple sensor inputs to compensate for changes in water temperature, pressure and flow.
Electronic Flow Control
The appliance can regulate available flow to help maintain the requested outlet temperature when operating conditions change.
Electronic Air Detection
The current DHE platform includes electronic air detection as part of its operating and protection system.
Why this matters: a high-output instantaneous heater still has a finite 28kW heating capacity. The DHE's premium control system is designed to manage that capacity more actively when flow or inlet conditions change.
WHO IT SUITS
Is the Stiebel Eltron DHE 27 AU Right for Your Property?
The DHE 27 AU is best suited to properties that need a higher-output electric continuous-flow system and already have, or can practically provide, the required three-phase electrical capacity.
Two-Bathroom-Class Applications
Stiebel Eltron's current Australian guidance recommends the 28–29.1kW instantaneous class, including the DHE 27 AU, as the starting point for a two-bathroom house. Actual simultaneous performance still depends on fixture flow and incoming-water temperature.
Premium Homes & Apartments
The compact wall-mounted design can suit properties where tank space is limited but more refined temperature and flow control is desired.
Commercial Applications
Stiebel Eltron also identifies suitable kitchen, commercial glasswashing and dishwashing applications where the required temperature and flow match the unit.
JR Installer Verdict: the DHE 27 AU is a premium instantaneous option, but the premium controls do not remove the need for correct sizing. Available amps per phase and peak litres per minute should be checked before selecting it.
HOW IT WORKS
How Does the DHE 27 AU Work?
The DHE has only a very small internal water volume. Water is heated while it flows rather than stored in a conventional cylinder.
Water Flow Is Detected
The appliance switches on once the flow through the unit exceeds approximately 2.5L/min.
28kW Heating Activates
The bare-wire electric heating system transfers electrical energy directly into the flowing water.
4i Control Manages Delivery
The fully electronic control system regulates power and flow to maintain the selected temperature as closely as operating conditions allow.
DHE 27 is not a 27 litre water heater. The “27” is the model designation. Current manufacturer data lists only approximately 0.4L nominal internal water volume because the system is instantaneous.

REAL-WORLD FLOW
DHE 27 AU Flow Rate & Temperature Rise
The useful output of any instantaneous electric water heater depends on the amount of temperature rise required. Higher flow gives each litre less available heating energy.
| 8L/min | Approximately 52°C temperature rise at 415V |
|---|---|
| 10L/min | Approximately 41°C temperature rise at 415V |
| 12L/min | Approximately 34°C temperature rise at 415V |
| 14L/min | Approximately 29°C temperature rise at 415V |
| 28°C Temperature Rise | Current Stiebel Eltron data lists approximately 14.3L/min at 415V |
| 50°C Temperature Rise | Current Stiebel Eltron data lists approximately 8.0L/min at 415V |
Example: at approximately 18°C incoming water, a 29°C rise at 14L/min gives a theoretical heated-water temperature of about 47°C before downstream mixing and other installation effects.
BRISBANE PERFORMANCE
Why Incoming Water Temperature Matters
Stiebel Eltron's Australian technical material uses approximately 18°C as a seasonal-average cold-water reference for Brisbane. The warmer the incoming water, the less temperature rise the DHE needs to produce.
Warm Inlet Water
Lower temperature rise allows greater useful flow from the same 28kW electrical input.
Cold Inlet Water
When incoming water is colder, more energy is needed for each litre and available hot-water flow falls.
Simultaneous Demand
Opening several showers, sinks or basins increases total flow and changes what temperature rise remains available.
MULTIPLE BATHROOMS
Can the DHE 27 AU Run Two Showers?
Stiebel Eltron's current Australian product guidance recommends its 28–29.1kW instantaneous class for a two-bathroom house, which includes the DHE 27 AU.
That is useful sizing guidance, but it is not an unconditional guarantee that two high-flow showers plus other outlets can always run without compromise.
Shower Flow Matters
Two efficient showers create a very different load from two unrestricted high-flow shower heads.
Season Matters
Colder incoming water increases the temperature rise required and reduces sustainable flow.
DHE Flow Control Helps
The DHE's electronic flow regulation is designed to prioritise maintaining the selected temperature when demand reaches the appliance's available capacity.
Size around peak simultaneous use. If several bathrooms, a kitchen and other fixtures are regularly used together, total flow should be assessed rather than relying on the number of bathrooms alone.
MULTIFUNCTION CONTROL
DHE 27 AU Display, Memories & ECO Functions
The DHE interface is one of the main differences between this premium model and simpler Stiebel Eltron instantaneous heaters.
Temperature Memories
Quick-access temperature memory buttons allow preferred settings to be recalled without repeatedly adjusting the temperature manually.
ECO Function
The DHE includes user-selectable ECO operation designed to support more economical water and energy use.
Live Information
The multifunction display can show information such as current power consumption, flow rate, time, status and service information.
TEMPERATURE CONTROL
20–60°C Precise Temperature Selection
The DHE 27 AU allows hot water temperature to be selected across a 20°C to 60°C range.
Bathroom Applications
Stiebel Eltron identifies the DHE for bathroom applications when suitable downstream delivery-temperature control is provided where required.
Kitchen Applications
The ability to select temperatures up to 60°C can suit correctly designed kitchen and commercial sink applications.
Temperature Compensation
4i Technology uses electronic sensing and flow control to compensate for operating-condition changes and maintain the selected setting.
A 60°C appliance setting does not mean 60°C should be delivered at every fixture. Personal-hygiene outlets must meet the applicable delivery-temperature requirements of the complete plumbing installation.

Yes. Stiebel Eltron currently specifies that the DHE can accept incoming pre-heated water for reheating applications up to 55°C.
Solar Boosting
Stiebel Eltron identifies solar boosting as one of the suitable applications for the DHE range.
Lower Heating Requirement
Warmer inlet water reduces the additional temperature rise that the 28kW heater needs to produce.
System Design Matters
The upstream system and controls still need to keep incoming conditions within the manufacturer's permitted operating limits.
INSTALLATION REQUIREMENTS
What Is Required to Install a DHE 27 AU?
Suitable three-phase supply with enough available capacity for approximately 38.9A per phase at 415V.
Dedicated fixed wiring correctly designed for the high electrical load, cable route and installation conditions.
40A manufacturer protection requirement integrated into a compliant electrical design.
Appropriate electrical isolation in accordance with current electrical requirements and manufacturer instructions.
Adequate water pressure and flow for the outlets and simultaneous demand expected at the property.
Correct hot and cold pipe sizing so avoidable plumbing restrictions do not reduce available performance.
Delivery-temperature control where required for bathroom and other personal-hygiene outlets.
Qualified plumbing and electrical installation followed by full commissioning and operational testing.
Three-phase supply alone does not confirm suitability. Stiebel Eltron specifically advises that available amps per phase should be checked. A property may have three-phase power but still need switchboard, circuit, cabling or supply upgrades before a DHE 27 can be installed.
INSTALLATION LOCATION
Where Can the DHE 27 AU Be Installed?
The compact 466 × 225 × 116mm design allows installation in places where a conventional storage cylinder would be impractical.
