Dux Proflo Review – Is This Hot Water Favourite Still Worth It?

When it comes to trusted hot water brands in Brisbane, Dux hot water consistently still sits comfortably near the very top. Known for its long history in Australia and Queensland and loved for its local manufacturing, Dux has been heating Australian homes for decades – and the Proflo electric storage range remains one of its most popular offerings.

Are you:

• Replacing a failed unit?
• Or planning a brand new hot water installation?

Either way, it’s well worth taking a closer look at the Proflo series before making a decision. Here’s what we’re going to do:

• Breaks down what the range offers
• Where it shines
• And what to keep in mind – especially if you’re shopping for performance, reliability, and value.

What is the Dux Proflo range?

The Dux Proflo series is a well-known line-up of electric storage hot water systems designed to suit a wide variety of household sizes. With tank sizes from 25L for small units to a super-generous 400L for large families or even commercial use, the range covers almost every scenario.

Each unit in the range is a mains-pressure system – meaning it delivers consistent flow across multiple taps at once, even during peak use. It’s a strong option for families that don’t want to compromise on water pressure during busy morning routines.

The tanks are designed and manufactured right here in Australia, and include smart features like:

• A larger-than-average anode
• Tough enamel lining
• And thick insulation to reduce heat loss.

If you’ve been browsing other Dux hot water system reviews, you’ll probably notice praise across the board for the Proflo’s quiet operation, straightforward design, and ease of installation.

Storage sizes that fit your home

We think one of the absolute standout features of the Proflo range is the variety of sizes available:

25L and 50L: Compact units ideal for tight spaces and single-person households.

80L-125L: Suited to small homes, units, or couples.

160L-250L: The sweet spot for medium households of 3 to 5 people.

315L and 400L: Best for larger homes or even commercial settings where demand is a lot higher.

All Proflo systems are vertical floor-standing models and include top-mounted electrical connections. Most are designed for both indoor and outdoor use, giving flexibility for tight floor plans or outdoor cabinet installs.

When you’re reading through a typical Dux hot water system review, you’ll often see mentions of easy swap-outs for older tanks. Why’s that? Because Proflo models are cleverly and conveniently built to match standard fittings and dimensions. That’s a huge plus when upgrading from an ageing system from many years ago.

What customers like

When you’re looking at Dux hot water system reviews online or talking to experienced plumbers like the team at S&J Hot Water Brisbane, you’ll definitely notice a few consistent positives:

Durability: Tanks are built with Y-class enamel – a super-tough coating designed to resist scale and rust, especially in hard water areas.

Insulation: Thick foam insulation helps reduce standby heat loss, making the system more efficient between uses.

Pressure: All Proflo models operate at full mains pressure, giving reliable, strong flow across your entire home.

Ease of installation: These units are very plumber-friendly and built to meet standard Australian installation specs.

There’s also a decent amount of praise out there for affordability. When comparing entry-level storage systems, Proflo hits a strong balance between price and performance – especially when backed by an experienced installer.

What to consider

It’s important to remember that no system is perfect, so a well-rounded Dux water heater review will mention a few things to keep in mind.

1. While storage systems remain popular, they’re typically less efficient than continuous flow or heat pump systems, particularly in larger households or high-usage homes. That’s not a fault of Dux – it’s simply the nature of electric storage.
2. Second, electric hot water systems may be subject to higher energy tariffs depending on your provider and connection. Installing the unit on an off-peak tariff can reduce this, but it’s worth discussing with your installer.
3. Lastly, larger models (like the 400L) are quite tall and bulky – so you’ll need a suitable space for installation.

What about the Dux hot water warranty?

When you’re buying any appliance that handles daily use, the warranty really matters – especially in a cost-of-living crisis. So how does the Dux hot water system warranty compare?

Well, Dux offers solid protection:

• 7 to 10-year tank warranty depending on the model
• 1-year parts and labour warranty on other components.

As with any warranty, terms apply – including proper installation by a fully-licensed professional such as an S&J Hot Water Brisbane plumber, and regular maintenance of the Dux hot water cylinder, including periodic hot water anode checks.

Still, this warranty coverage stacks up well in the market and clearly reflects Dux’s confidence in its products and reputation over many years.

Dux hot water reviews: The verdict

In short, the Proflo range is a well-rounded offering that delivers exactly what most households need – reliable, Australian-made hot water with options to suit any property size.

Here’s a quick breakdown based on what we’ve seen in other Dux hot water reviews out there, as well as from our own hands-on experience:

Ideal for: Homes looking for a reliable replacement, rental properties, and budget-conscious upgrades

Strengths: Range of sizes, solid warranty, easy installation, strong performance

Watch out: Bulkier models need space, not the most efficient for high-use households.

So, Proflo is not a system that tries to reinvent the wheel – but that’s actually a good thing in this case. Simple, well-built, and supported by a strong local service network, the Proflo range continues to be a go-to for Brisbane households like yours.
