Build Your Optional Supply & Install Package

Answer a few quick questions to confirm whether you can order this package online or need a quick install check first.

Are you replacing an existing hot water system?

This helps us work out whether this looks like a standard replacement.

Are you replacing the same hot water system, identical make and model?

If yes, the valve kit is recommended. If not, it is required at the end.

Is it going in an existing location?

Existing location means the new system goes back in the same general position.

Where is the system located?

If outside, continue. If inside or under a house, complete the 60sec Check first.

Are you changing system type, electrical connection type or needing to extend your electrical connection?

If yes, an electrical extension or new circuit may be needed, or you can organise your own electrician.

Do any site access issues apply?

If any access issue applies, we will add the 2-man install option and continue.

Does your current installation meet current compliance requirements?

If no or unsure, we will recommend a valve kit or extra works as the safer starting point.

About the Dux Proflo 125L Electric Hot Water System

The Dux Proflo 125L is part of the Dux Proflo electric storage range, built for Australian homes and conditions. It is designed to provide dependable stored hot water with full flow pressure to all outlets.

The Proflo range uses durable Y class commercial grade enamel, a larger anode to help increase tank life, a hard-wearing polymer base to resist damage and moisture, and water connections on both sides of the tank to make replacement installation easier.

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.

Important Installation Notes

Installed Today supplies the product and helps arrange installation through licensed installation partners where available. Installation is only available on selected products and in eligible service areas.

The install package price applies to the selected installation scope shown at checkout. Final suitability still depends on site access, existing plumbing or electrical setup, valves, drainage, compliance requirements, product suitability and any extra work required.

If something outside the selected package is needed, it will be discussed before proceeding.

Supply-only orders do not include installation, old unit removal, disposal, valve kits, electrical work, plumbing alterations or compliance upgrades unless these are clearly selected or included in your order.

A Simpler Way to Buy Hot Water, Filters, Pumps and Plumbing Products

Buying a new hot water system, water filter, pump or plumbing product should be clear, simple and easy to organise.

Installed Today helps you compare products, check supply-only pricing and, where available, build an optional installation package before checkout.

Whether you already know exactly what you need or you are still comparing options, Installed Today gives you a clearer way to buy the right product for your home, budget and timing.

Why Customers Choose Installed Today

Supply Only or Optional Installation

Choose the product on its own, or add installation where available on selected products and in eligible service areas. This gives you the flexibility to order the way that suits you best.

Clear Pricing Before Checkout

See the product price upfront, then review available installation options and common add-ons before placing your order. You can check the package total before checkout, instead of waiting on basic pricing just to get started.

Product Details That Actually Help

Key specs, sizing details, warranty information, product features and suitability notes are shown clearly, making it easier to compare products properly before you buy.

Common Installation Add-Ons Available

Where relevant, you can add common installation extras such as valve kits, bases, access-related items, removal, electrical options or other site-specific upgrades before checkout.

Built Around Brisbane and Gold Coast Homes

Our product and installation options are selected with common Brisbane and Gold Coast homes in mind, including local water quality, access issues, plumbing layouts, replacement requirements and typical installation conditions.

Choose supply only if you just need the product.

Choose an optional supplied and installed package where installation is available and you want the product and selected install options organised in one order.

Add common extras before checkout if your job needs additional parts, removal, access support or site-specific options.

It is a simpler way to organise the product, the selected extras and the parts of the job that matter most.

Important Installation Note

Installation availability, inclusions and add-ons vary by product type, service area, site access, existing services, selected options and property requirements.

Some jobs may require additional work, upgrades or checks before installation can proceed. Final suitability may need to be confirmed based on site conditions, plumbing, electrical requirements, valves, drainage, access and compliance requirements.

Fast Delivery and Install-Aligned Shipping

Installed Today makes delivery simple, whether you are ordering supply-only or choosing an optional install package.

For supply-only orders, you can select from available delivery options at checkout. For eligible orders with installation selected, shipping is included and coordinated to align with your selected installation period where possible.

Delivery Options

Same Day Delivery

Same day delivery may be available for selected hot water systems in Brisbane and Gold Coast metro areas when ordered before 7:00am.

Availability depends on stock, courier capacity, delivery location, product type and safe transport conditions.

Express Delivery

Express delivery is available on selected products and locations, with an estimated delivery timeframe of 1–4 business days.

Standard Delivery

Standard delivery is available on selected products, with an estimated delivery timeframe of 2–8 business days.

Free Shipping with Installation

Fast Metro Delivery

Most hot water orders in metro areas are delivered quickly, with many arriving within 1 business day depending on stock, location, order time and courier availability.

Weather and Transport Delays

Hot water systems are large, heavy products and cannot always be transported safely during rain or unsafe handling conditions.

Delivery timeframes may be affected if wet weather impacts loading, unloading, transport access or safe delivery conditions.

Express Delivery Refund

If your express delivery order takes longer than the estimated 1–4 business day express timeframe, your order will move to the standard 2–8 business day delivery timeframe and your express shipping charge will be refunded automatically.

Order Tracking

We will send your delivery details once your order has been dispatched or scheduled.

For supplied and installed orders, delivery timing may be coordinated around your selected installation period rather than sent as a separate courier-only delivery.
