Had an old Dux Proflo which lasted up to 20 years when it began leaking. Tried to search for a new unit as soon as possible and Dux was the only company that were easily accessible (alongside organised service through Bunnings), so it was decided to stick with the same brand.

The installation of the unit was quick and efficient. There are no regrets so far as everything works fine and it is quick and easy to get constant hot water. Great value and product, especially with the time and hassle saved by Bunnings organising installation for Dux products.

We replaced our Dux Proflo which we had for almost 20 years with a Prodigy 4, so far it’s been very good,4 Adults and we don’t run out of hot water.
In our experience Dux are a long lasting and reliable hot water heater.

15yr old gas Dux 135L replaced with same. Old unit was leaking slowly but still functioning. Ordered through Bunny’s and their independent plumber and installed next day as arranged. In-store price of unit alone $854. Learned that the corrosion protecting anode could have been replaced at about 5 yrs. for longer life. Had no issues with old Dux which is why I chose Dux again. Aways had plenty of constant hot water and never had to have repairs or attention to the pilot light.

No issues at this point in time; it is meeting my expectations based on older Dux heater. Trust it will give the same service as previous model which gave reliable service for many years.

This unit performs well, providing good hot water service to 4 adults. On the rare occasion that the water storage runs out it reheats reasonably quickly.

My one complaint is that the pilot light blows out frequently. To combat this we tape the door shut to prevent the wind disturbing it.

Compounding this the lighting unit has had to be replaced at least twice, and will probably be replaced a third time tomorrow. Although the first failure was covered by warranty, the second wasn't and we are averaging one replacement a year.
It's almost impossible to light the pilot manually. This is inconvenient and expensive and while the unit otherwise functions very well I wouldn't buy it again for this reason.

My old unit was a dux, it worked brilliantly for 20yrs! The new dux is also
- extremely efficient
- amazing value
- quiet
- provides constant hot water
The entire process from quote to installation was so professional and prompt.

Excellent capacity for my household needs. The hot water comes through quickly with no wastage. The changeover from my 18 year old DUX Proflo was organised through Bunnings. Outstanding Service!

Our previous 20yo Dux hot water system finally died and we needed to replace it urgently. We went through Bunnings and decided on the larger 135ltr Dux. It does everything you expect from a quality product and was installed within 24 hrs of our other one dying. Excellent product and service from Bunnings.

I brought the product from Bunnings with installation and couldn't fault the whole process, my last Hot Water System was also a Dux and lasted almost 20 years...Fantastic product and works a treat. This is one happy customer

I don't have any issues with temperature fluctuations. There are only 2 users in the houshold. This DUX unit works perfectly for us. I am happy to recommend tit to anyone.

I recently replaced my old Dux with a new Dux Prodigy 4 135L. I could not be happier with the service I received from Bunnings, where I purchased the unit and the same applies to the Serviceman that delivered and installed the new unit they were very prompt and the serviceman was courteous and efficient. Everything is working beautifully and if I get the same from this unit as I did my last Dux unit which was 17years old, I will be ecstatic.

Great warranty service from Dux after I contacted the Head Office warranty support team about leaks in my 5 year old Dux Prodigy 5 unit. After an arranged inspection by their helpful Canberra representative (from Greaney & Sweeney), Dux agreed to replace the old unit with a new Prodigy 4. Noting some of the pilot light problems with the Prodigy 5 I was happy to agree to the Prodigy 4. A few days after Dux approved the replacement, the installer from Greaney & Sweeney, Matt, was very professional, friendly and helpful. I'll post a follow up performance comment on the Prodigy 4 in the coming months especially as we have more cold nights and early mornings ahead of us in Canberra!

I had this product last couple of year and recently changed new one because product has good quality of heating system, continuous hot water flow, gas saver, economical. The installation service was one time , lady on customer service help me saved my$50 on product as it was overcharged from warehouse. Hot water running smoothly now .

More than happy with the unit, it heats up quickly, very efficient, looks good & fits in the space provided Perfectly! I will recommend it to my friends & family! 5 stars for me!!

I've had the system for 2 weeks now - 135L Prodigy. I bought it through Bunnings and installation was through Dux. The installer was very punctual and reliable. He installed the system, took away the old one in one hour. The system is great.
But I haven't got my Compliance Certificate yet from Dux, the installer said it would be sent to me. It's 2 weeks and I'm still waiting. I'm not sure when I will get it. The office told me I would get it a couple of days after my installation (ie nearly 2 weeks ago).
This is my first Dux system, and the second hot water system I've ever bought. (My first one was Vulcan hot water system, it lasted 24.5 years).

We have had Dux for last 15 years. Had no problems with it at all that's why we changed it to dux again. We had a quick turnaround and customer service was excellent.

Our recent replacement was for our older DUX unit, which hasn’t given my family any issues. The New unit works exactly as expected - no issues with the water temperature and it handles the high demand for a family of six very well. Would recommend this to anyone - also great service with the installation

The unit Dux Prodigy 4 135ZB4N/135ZB4P (135L) has performed well about the water temperature and water pressure with two showers at the same time (3 person) and kitchen use. Completely there is no issue with temperature fluctuation during usage this unit.

when you turn on the tap it takes only a few seconds to have hot water, the improved burner really works well. I'll recommend this product to all my friends.

Two months after installation (and 2 gas bills later), the new model is significantly more efficient than my previous GHWS. Much greater insulation visible, but still nice and compact. Contract installer was a ripper fella too!
