Great choice for small family

This is the second Dux 135l prodigy 4 I have had installed, one at our home about 2 years ago,the other at our investment unit just a few days ago. Both installs were seamless and the Dux Prodigy4 at home has performed without a hitch and I expect the second one will be just as reliable delivering hot water to our tenants. I can recommend Dux gas hot water services to anyone considering a replacement install. Show details ·  1

Didn't last Five years DON'T BUY

This system went rusty and failed at 4 years 10months then to rub salt into the wound was without hot water for several days and had to fork out an additional $550 for installation of a warranty new cylinder which Dux don't even stand by under a new warranty but only remains of the original system, trust me you don't need to lose out this much financially but another brand these are garbage Show details

Excellent Hot Water Unit

The Dux Hot Water unit does what it says it does. Hot water! With a family of 5 the unit copes well, while being energy efficient. Has all the modern features with the added piece of mind of a three year warranty. Purchased at Bunnings and am extremely happy with it. Show details ·  1

Perfect speedy replacement after old system failed just before Christmas

Our old unit stopped working 9 days before Christmas and we were in a panic.
Bunnings online made it very easy to get a new system.
Price was great, sales team were knowledgeable, answered all our questions and there were no hidden extras.
The Dux installer arrived on time, was polite, efficient with the installation and took the old system away.
We are extremely happy, our new Dux was installed 6 days before Christmas Day and handles the demand from two bathrooms very well. Show details ·  1

Have a Dux Prodigy gas Hot water service 11 yrs. old, now leaking with rusted tank. Thinking of purchasing another as the first has been very efficient til now. Does the vitreous enamel lining give a longer lifetime to the tank. My 1st hot water service lasted 18 yrs. and some reviews mention 20 yrs. Nearing retirement and want to purchase something that will last. Looking at Dux Prodigy 4 135ZB4N. Thanks

Our HWS has recently started making loud banging noises when HWS is being used in the house. It is not water hammer, is louder than the rumbling sound that can occur with gas systems due to sediment accumulation and the noise is definitely coming from the unit. The hot and cold water valves have been regularly released and the system was installed just under 3 years ago by our regular, professional plumber.
Having lived in a variety og homes with a variety of HWS, we have never experienced this before and can't accept that it is 'normal'.
