Our builder installed 2x 2016 one at each side of the house. We have started to have constant problems with one in particular which keeps blowing out. I relight and it sometimes lasts a couple of days until this week. When I was lighting it it caught on fire and the flames came gushing out towards my face. At this point I have realised that this has been happening previously as the vents at the top are black with smoke and inside smoke marks also. Until this point we were happy with the system but don't know what to do now as not in the position to replace it.

I’ve had the dux for just over 3 years. Since having the system at least once a month the light would go out and I would need to reignite, yes annoying but still got hot water. Start of this year this was happening more frequently until the pilot stopped working. Called dux, out of warranty period got plumber over, spent$400 for new thermostat and burnt all the polystyrene inside. 5 months later same problem. My unit is not even 5 years old and it’s looking like I need to replace. Not fair and not happy!!!!

We are a family of 4 and the unit served us really well. I loved my Dux.
Bough them from bunnings including installations for less than $1500.00
They deliver and install the unit in 2 working days.

What a piece of rubbish, same issue as others, the flap at the top stops working rendering the heater useless. This is a design flaw but instead of being helpful in fixing it you are told there is only a one year warranty and good luck. The tank may last 10 yrs but the flap seems to have a life of 2 to 3 yrs. Wow, what a rip-off.

Worst hot water unit in the world. If DUX can’t build something as simple as a water heater, maybe they are in the wrong business. My home brand kettle does a better job. Companies like this won’t last long especially in this day and age with social media and product review. Only a matter of time before these guys close shop due to no sales. Pilot light keeps turning off. Inconsistent water temperature. Very noisy system.

Had problems with this from the first year (2013) it was installed. As lots here have experienced, the pilot light kept going out. As it was within the first year of installation, a technician came by and fixed the issue at no cost. Four years later, the unit has now completely stopped working. As it was going to cost hundreds to fix, I opted for a new unit but from a different manufacturer. Never buying a Dux unit again. Beware.

Dux hot water system is very Problematic system. System won’t work after warranty period(12 months). Very bad customer support. They are saying I am unlucky person to get faulty system and I need pay the repair cost. i had problems from when they installed.
I saw other reviews and everyone has same problem. Hence not recommended

I changed to a dux after being recommend from bunnings. The pilot light goes out once a month so I'm coming home to a surprise cold shower and my gas bills have risen dramatically and no help from due on the issue. do yourself a favour and buy a different brand

Hopefully the one that is getting installed right now is not as bad as all these terrible reviews - feeling nervous and anxious i must say. I'll update my review after 12 months hopefully i doubt get a lemon like a lot of others and my review can stay at 5 stars - time will tell i guess

After merely 6 years my DUX Prodigy 3 hot water service fails. The original unit it replaced lasted 19 years. Because of space limitations unfortunately had to install another DUX. Hoping to get more than 6 years this time with the Prodigy 5. Seriously, 6 years for a water heater costing $1000 is pathetic. One can only hope the new one lasts past the warranty expiry date.
