ABOUT THE SYSTEM
About the Dux Proflo 250L Electric Hot Water System
The Proflo 250L stores electrically heated water ready for household use. Dux positions the Proflo large electric range as a practical replacement option for existing electric storage water heaters, with tank sizes from 80L through to 400L.
The 250L model sits between the 160L and 315L units and can suit family homes requiring more stored hot water than smaller electric storage systems.
Dux lists the 250L Proflo for approximately 3–5 people. Actual suitability depends on shower duration, household routines, appliances, climate, electricity tariff and the time available for the system to reheat.
WHO IT SUITS
Who Is the Dux Proflo 250L Best For?
Family Homes
Dux lists the 250L Proflo for approximately 3–5 people, making it relevant to many family households with moderate-to-higher daily hot-water demand.
Electric Storage Replacements
Water connections on both sides of the cylinder can make compatible replacement installations easier when replacing an older electric storage system.
Indoor or Outdoor Locations

CURRENT MODEL
Dux 250T1 Electric Storage Configuration
250T1
The current Proflo 250L model is 250T1. Dux specifies one 3.6kW element for the current Australian range.
240V Single Phase
Dux states that current Proflo electric storage models operate on 240V AC single-phase electricity. Electrical suitability must be confirmed before installation.
Older Dux documentation may show additional historic element variants in extended model codes. The current January 2026 Dux product guide lists the 250T1 with a 3.6kW element.
SIZING
Is a 250L Electric Hot Water System Right for Your Home?
Dux currently lists the Proflo 250L for approximately 3–5 people, but household size should only be treated as a sizing guide.
A household with long showers, multiple bathrooms or high hot-water appliance use can consume considerably more water than another home with the same number of occupants. Electricity tariff availability is also important because restricted or off-peak tariffs limit when the tank can reheat.
It May Suit You If...
You are replacing a similar-sized electric storage heater or need greater stored capacity than a 160L system.
Check Your Tariff
Dux notes that off-peak supply may only provide power for a limited period each night, so tank sizing and usage need to suit the available heating window.
Check the Existing Site
Confirm physical access, base support, plumbing, valves, drainage and electrical supply before ordering the system or an installation package.

INSTALLATION LOCATION
Can the Dux Proflo 250L Be Installed Indoors or Outdoors?
Yes. Dux lists the Proflo 250L for indoor or outdoor installation.
The cylinder must be positioned on a flat, solid supporting surface. Dux specifically states that connected pipework must not be used to support the water heater.
For indoor installations, a properly drained safe tray is required where water leakage could cause property damage. The final installation must also meet local plumbing requirements.
INSTALLATION REQUIREMENTS
What Is Required to Install the Dux Proflo 250L?
Dux states that its Proflo electric storage water heater must be installed by a licensed tradesperson and in accordance with relevant plumbing, electrical and authority requirements.
- Flat and solid supporting surface
- Suitable hot and cold water pipework
- Correct Pressure & Temperature Relief valve arrangement
- Suitable cold-water isolation and non-return arrangement
- Pressure-reducing valve where supply pressure requires it
- Correct relief-valve drainage
- Suitable delivery-temperature control where required
- 240V AC single-phase electrical supply
- Electrical circuit suitable for the 3.6kW element
- Fixed-wiring isolation in accordance with applicable wiring rules
- Safe tray and drainage where required indoors
- Access for element, thermostat, relief valve and anode servicing
- Compliance with applicable plumbing requirements
- Electrical installation compliant with AS/NZS 3000
WATER PRESSURE
Dux Proflo 250L Water Pressure Requirements
Dux's current technical information specifies a 1000 kPa Pressure & Temperature Relief valve for the 250T1.
The Proflo owner's manual states that the 250L model is designed for direct connection to water-supply pressures up to 800 kPa.
Where the mains pressure can exceed or fluctuate beyond the permitted inlet pressure, Dux requires an appropriate pressure-reducing valve in the cold-water supply.
FULL MAINS PRESSURE
Full Mains-Pressure Hot Water
Dux specifies full flow pressure to all outlets across the Proflo large electric range.
This makes the Proflo 250L a practical replacement option where the home already uses a conventional mains-pressure electric storage system.
Actual flow at individual outlets also depends on the property's incoming water pressure, valve arrangement, pipe sizes and plumbing layout.
INSULATION
50mm Dense Foam Insulation
Dux specifies 50mm thick dense foam insulation for its large Proflo electric storage water heaters.
The insulation reduces heat loss from the stored water between heating cycles. Actual running costs depend on household consumption, electricity tariff, climate and the available heating period.
HARD WATER
Is There a Hard-Water Option?
Yes. Dux lists a hard-water option for the Proflo 250L.
For the 250T1, Dux publishes different replacement sacrificial anodes for average-to-hard and extremely hard water conditions. Correct anode selection and servicing can be important where local water chemistry is aggressive.
Where water quality is unusual, confirm the appropriate configuration and maintenance requirements before installation.

Tempering Valve and Element Information
*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.
If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.
Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.
Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.
1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.
This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.
Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.
**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.
