DUX PROFLO COMPACT ELECTRIC STORAGE HOT WATER
Dux Proflo 50L Electric Hot Water System – 50S124P & 50S136
The Dux Proflo 50L Electric Hot Water System is a compact mains-pressure electric storage water heater designed for smaller hot-water applications and locations where installation space is limited.
Dux currently lists two 50L configurations: the 50S124P 2.4kW plug-in model and the 50S136 3.6kW hardwired model. Both provide a genuine 50 litres of storage and 50 litres of rated hot-water delivery in a cylinder measuring just 670mm high × 405mm diameter.
Installed Today offers the Dux Proflo 50L as a supply-only water heater or with supply and installation across eligible Brisbane and Gold Coast service areas.
Dux Proflo 50L at a glance: a compact 50L electric storage water heater with 50L actual storage and delivery, 2.4kW plug-in or 3.6kW hardwired configurations, 670mm height, 405mm diameter, V-Fit dual-sided plumbing connections and full mains-pressure delivery. Dux's January 2026 sizing guide lists the 50L for approximately one person on a continuous electricity tariff.
ABOUT THE SYSTEM
About the Dux Proflo 50L Electric Hot Water System
The Proflo 50L stores electrically heated water close to where it is required. Its compact dimensions make it particularly useful where a conventional larger electric cylinder is unnecessary or will not fit.
Dux specifically highlights kitchens and laundries as applications where installing a small electric water heater closer to frequently used outlets can reduce the wait for hot water compared with relying on a remotely located main water heater.
Unlike Dux's Australian-made 80L–400L Proflo range, the 25L and 50L Proflo models are manufactured in an overseas Noritz manufacturing facility.
WHO IT SUITS
Who Is the Dux Proflo 50L Best For?
Single-Person Applications
Dux's current sizing guide lists the 50L model for approximately one person on a continuous tariff, subject to actual hot-water demand.
Kitchens & Laundries
The compact system can be installed closer to frequently used hot-water outlets where a dedicated small storage heater is appropriate.
Tight Installation Spaces
At only 670mm high and 405mm diameter, the 50L Proflo is specifically designed to fit selected cupboards and other compact installation areas.

SIZING
Is a 50L Electric Hot Water System Right for You?
Dux's January 2026 sizing guide lists the Proflo 50L for one person on a continuous electricity tariff. No off-peak household rating is published for the 50L in that guide.
The 50L can also be useful as a dedicated small storage heater for selected kitchens, laundries and similar low-demand applications where total hot-water use fits within the available storage and recovery capacity.
It May Suit You If...
You are replacing another compact 50L storage heater or need a small mains-pressure heater near frequently used fixtures.
Continuous Tariff
Dux's current sizing guide gives the 50L a one-person rating where electricity is available for reheating throughout the day and night.
Check Actual Demand
Shower use can consume a 50L tank quickly. Fixture flow rates, usage frequency and required recovery time should be considered before choosing this capacity.
KEY FEATURES
Key Features of the Dux Proflo 50L
Compact 670mm Height
Dux designed the current 50L cylinder specifically to fit more easily into tight cupboards while maintaining a full 50L hot-water delivery rating.
V-Fit Plumbing Connections
V-Fit dual-handed connections provide accessible plumbing positions on both sides of the cylinder for compatible installations.
Plug-In or Hardwired
Choose the 2.4kW 50S124P plug-in configuration or the 3.6kW 50S136 hardwired configuration according to the installation.
Full Mains Pressure
Dux specifies full-flow pressure to connected outlets rather than a gravity-fed low-pressure arrangement.
Adjustable Thermostat
Dux includes an adjustable thermostat for variable stored-water temperature within the manufacturer's permitted settings.
Hard-Water Option
Dux lists a hard-water option for the small Proflo range where local water conditions require a different configuration.

COMPACT INSTALLATIONS
Can the Dux Proflo 50L Fit in a Cupboard?
The Proflo 50L is specifically designed to make compact cupboard installations easier. Dux highlights its 670mm overall height, which is up to 25mm shorter than some other 50L-rated electric water heaters.
Physical tank dimensions are only one part of the installation check. The location must also provide room for plumbing connections, the PTR valve and drain, electrical equipment and future servicing.
Dux requires the compliance plate and service components to remain accessible and specifies clearance for servicing the element, thermostat, relief valve and sacrificial anode.
INSTALLATION LOCATION
Can the Dux Proflo 50L Be Installed Indoors or Outdoors?
Dux's current 2026 range brochure identifies the 25L and 50L Proflo range for indoor or outdoor installation.
The actual location still needs to comply with Dux's installation instructions and electrical requirements. Hardwired installations require correct weatherproofing of the electrical conduit entry where exposed to weather.
For plug-in configurations, the power outlet and installation environment must also be suitable and compliant for the selected location.
Where an indoor installation could cause property damage if leakage occurs, Dux requires a properly drained safe tray.
INSTALLATION REQUIREMENTS
What Is Required to Install the Dux Proflo 50L?
Dux states that the water heater must be installed by a licensed tradesperson in accordance with applicable plumbing, electrical and local authority requirements.
- Flat, solid supporting surface
- Suitable hot and cold water pipework
- Correct 1000 kPa PTR valve installation
- Compliant PTR drain line
- Suitable cold-water isolation and non-return arrangement
- Pressure-reducing valve where supply pressure can exceed 800 kPa
- Expansion-control valve where required by local regulations
- Suitable delivery-temperature control where required
- 230–240V AC single-phase electrical supply
- Correct electrical arrangement for plug-in or hardwired model
- Safe tray and drainage where required indoors
- Service access to the element, thermostat, PTR valve and anode
- Installation in accordance with applicable plumbing requirements
- Electrical work compliant with AS/NZS 3000
WATER PRESSURE
Dux Proflo 50L Water Pressure Requirements
Dux specifies a 1000 kPa Pressure & Temperature Relief valve for the Proflo 50L.
The water heater is designed for direct connection to water-supply pressures up to 800 kPa.
Where mains pressure can exceed or fluctuate beyond 800 kPa, Dux requires a suitable pressure-reducing valve to be installed in the cold-water inlet supply.
FULL MAINS PRESSURE
Full Mains-Pressure Hot Water
The Dux Proflo 50L delivers full-flow mains-pressure hot water to connected outlets.
This allows a compact storage system to be used without moving to a low-pressure gravity arrangement. Actual fixture flow still depends on the property's incoming pressure, pipe sizing, valves and plumbing layout.
PLUG-IN OPTION
How Does the 50S124P Plug-In Model Work?
The 50S124P is Dux's current 2.4kW plug-in Proflo 50L. The “P” suffix identifies that it is factory fitted with a power supply cord.
Dux states that pre-wired models may be connected to a suitable standard general-purpose power outlet. The outlet and complete installation must still comply with applicable electrical and installation requirements.
The water heater itself must still be installed correctly by a licensed tradesperson. A plug-in electrical connection does not make the complete hot-water-system installation a DIY plumbing job.
HARDWIRED OPTION
How Does the 50S136 Hardwired Model Work?
The 50S136 uses a 3.6kW element and does not have a factory-fitted power cord.
Dux specifies that hardwired electrical connection must be completed by a licensed tradesperson, with an appropriate means of disconnection incorporated into the fixed wiring in accordance with the Wiring Rules.
The 3.6kW element provides greater heating power than the 2.4kW model, but the existing electrical circuit must be suitable for the higher load.

MAINTENANCE
Dux Proflo 50L Maintenance
Dux recommends regular servicing to help extend the life of the water heater and maintain safe operation.
The owner's manual specifies a six-month check where the owner can operate the PTR valve easing lever for approximately 10 seconds and confirm that water discharges correctly through the drain.
Dux also recommends a five-year service by a licensed tradesperson. Where Total Dissolved Solids exceed 600 mg/L, the recommended interval is reduced to 3 years.
The major service includes replacement of the PTR valve and sacrificial anode, inspection and flushing of the expansion-control valve where fitted, draining and flushing the tank and inspecting relevant electrical components.
