Need a service agent in Western Australia
No service agent in Western Australia. Our plumber was told to drain and refill unit he wasn't able to check the anode. The unit hasn't been used in 3 years (7 year old unit) . Had it switched of for 5 days before we moved in and had really hot water. Now it's barely luke warm, unable to heat up.
Biggest piece of rubbish ever
control board failed within 6 months but replaced under warranty. The unit has lasted 8 years (which is pretty good compared to what others have experienced) and now rusted out completely.
Purchased in March 2012 for $3,000.00.
Thank you to Dux after product Failed
New home was built in 2014, with this system installed. Airoheat pump worked fine until tank sensor stopped working on just over 5 years usage and was unrepairable. We were told a new system was our only option, and quoted around $3800. As the unit had not been used for more than 6months due to us travelling , this was an unacceptable outcome. We applied under Duxs fair go policy to replace the unit. Thank you to Dux for providing a new Airoheat Pump and standing by your product. We are very happy with the outcome and would recommend your prompt after sales service. In our experience Dux listened and acted immediately on their customers behalf.
I cannot recommend this "Dux Airoheat Heat Pump "
I live in Harrington NSW. I replaced a 11 year old Quantum Heat Pump with the Dux Airoheat - heat pump on the 7/12/2016. The heat pump worked fine until the cooling fan started vibrate badly. I contacted the DUX agent in Taree. they sent out a service man to check the problem. The problem turned out that the fan blades had badly rusted . The cooling fan was replaced under "Warranty"30/05/2019. On the 17/10/2019 the heat pump failed to heat the water. Dux agent was contacted and sent out a service man. He found that the " refrigerant unit had fa...iled " on a phone call to Dux Australia he was informed that the unit was out of "warranty" and the customer would bear the cost of repairs. After less than 3 year of use I decided the cost of repairs was not worth it. I have replaced the Dux unit with a " Stellar Stainless steel Electric water heater" with a 12 year leakage Warranty. This is why I would not recommend the Dux Heater as reliable heater unit.

I wouldn't recommend a DUX
We had a DUX system installed when our house was built, so we personally did not choose the system. After living in our home for 13 months, the heater stopped working altogether (in the middle of winter!). We called for a plumber to fix it, and when he phoned DUX technicians, it was then noted that it was a design fault and DUX offered to replace the unit, although we had to pay for delivery and installation fees. And for some reason, they had our new unit delivered to a REECE store so we then had to somehow, work out how to get it delivered ...to our home. Why it wasn't delivered directly to our home, I still question this. So we got the new unit and it works however, it is loud when heating the water. I was sitting in my study room (9 metres away from the unit) and I heard this loud rumbling noise, and I went outside to see what it is and it was the unit - our original unit did not make this sound. Personally, I wouldn't recommend a DUX. If this was turns out inoperable (which we are expecting it to do so), we will simply fork out thousands for a whole different and better brand.

It makes heavy noises like metal hitting each other.
My neighbor has the same one installed a few years ago, recently it makes heavy noises day and night, my bedroom window is just next to it. I couldn't sleep when it runs.
I don't recommend DUX products.
10 years and going strong.......
Installed in 2009, hasn't missed a beat. The only negative is the fan on top rust away (l've replaced it once and rust-proofed the 2nd) but l'm right on the beach. Cheap to run and quiet enough that l don't notice it. Must admit l'm surprised as l read the mostly bad reviews after l had it installed........
Great at first, downhill from Year 6
Had this unit installed at my parents place back in 2009 to replace a previous Dux system that leaked and also had reached 12 years of service, we chose this model as it was a lower kW compared to others in hope to save some money on the power bill. The unit worked quite well for a few years until the 6th when issues began to arise. The pressure from the tank was quite weak, yet mains was strong, that was due to a faulty valve and to replace that was almost 2K in parts and labour which was a bit steep, could have replaced it instead. Even afte...r this service and a general service (not included in the 2k) and following the manuals minor maintenace, we would go up to 2 days without hot water due to the condenser failing to work at times which caused significant ice build up at the top of the unit, sometimes 3 to 4 inches thick which had to be removed manually to kickstart the unit to work (I am aware of the ice build up stated in the manual but should not be that thick) and now recently electrical faults have arised with it tripping the circuit breaker numerous times and an electician inspected the wiring and stated the fault is within the tank itself. As it endures its 10th year, it is being replaced with a different brand unit. Quite disappointed with Dux giving the cost of this unit and how many issues that have arised with it.

System needs replacing after 5 years due to design flaw and no help from Dux
This system was installed when our house was built at the beginning of 2014 and up until this point has worked well.
The system has currently been in use for about 5 and a half years and unfortunately is now causing brown water to flow from the taps. We had a plumber who was an official Dux repairer have a look at it and were told that the discoloured water is in fact caused by sludge in the bottom of the tank, which is produced during normal operation due to some sort of chemical reaction. The problem has evidently been improved on later machi...

What an absolute lemon
Just under 2 years old and system died caused by a system defrost which leaked into the main control unit. Complete design fault but yet no warranty. What a joke
Purchased in July 2017.
Purchased this heat pump hot water system 2011 with our new home. No hot water under high demand. In 2014 the electronics failed then in 2016 the tank failed after rusting. New system fitted under warranty but had to pay labor. It failed now 6/2019 and now refused warranty even though the tank has 10 year warranty. Not acceptable from an Australian co. I even asked for 1/2 and 1/2 but no. Don’t buy.
Purchased in April 2016.
We have had the Dux Airoheat for at least 8 months now and have no problems at all with the system. There has been no water leakage at all, it is quite to run, we have at times 8 members of the family in the household for extended periods of time and keeps up with plenty of hot water for all jobs necessary. I’m glad we made the decision to purchase the Dux Airoheat.
Purchased in August 2018 at Bunnings Warehouse for $2,000.00.
Do not buy
We have endured 2 of these pathetic heaters. First one started giving us rust after 4yrs then total tank failure at 5.5yrs.
Dux did replace under warranty and this second unit has lasted 2.5yrs.
I am currently dismantling this one to see what the hell is going on inside these tanks.
I am amazed that people don't research such an expensive item before purchasing!
Dux you should remove this item from the shelves!
Please watch the YouTube video and share as much as you can and we may save some poor soul from going through the same problem.

This deserves no stars, one is being generous
This product should be removed from the market as it's got to be a safety risk. Our builder installed this heap of junk when we built. If I'd known more about hot water systems I would have done some research and chosen something that wouldn't put my families health at risk. Over a period of a month this pathetic excuse for a hot water system has been turning our water orange. Orange water comes from all our house taps after the hot water has run. We then have to clear the system by running cold water for many minutes. Plumbers hate these...units, as soon as we contacted a plumber he knew what the problem was and asked if we had a dux heatpump. We contacted several plumbers for second and third opinions... all had the same answer. The unit is 7 years old but seriously turning water orange.?? It would be better if the thing just stopped working instead of polluting our drinking water system. Apparently it's very common for these units to pump their vile waste into the plumbing system. Do yourself a massive favor and stay away from this brand completely. For a unit that costs $3,000 you'd except an amazing unit. Plus they are super super noisy and so not worth investing in. Heap of junk.

Good but designed to be redundant
Hi had a Dux Radiant Heat pump installed in early 2012. The thing is noisier than an old box aircon som is completely inappropriate in high-density areas, like units. I had it put on timer so it turned off at night and turned on in the morning, I was always able to have hotwater in the morning as the insulation is good. The fan unit failed after three years and a contractor came out and fixed it but they charged me $200 to replace a part. A year later the thing started leaking and by then 5 year tank warranty had expired. I rang Dux to get some...one to fix it, they said to call a local plumber. PRETTY LOUSY that they can't get people to fix their own product even if I was willing to pay. The plumber basically informed me the unit had 'shat itself' and the leakage was rotting the tank. So basically it's redundant as soon as the warranty expires. So much for 'sustainability;!
Have to replace every 5 year!
I have had 4 Dux units since 2005. The common problem was water leaks from the top. Always breaks down just after warrantee has expired a a few months! My third one leaked just after 3 years and was replaced by a new one which started to leak after 4 years. Gave them a call today but they said that it is not covered under warranty cos they included the 3 years from the previous one. So don't buy Dux, they don't last long!!!!!
I first purchased one of these units in 2007. 3 weeks after the 5 year warranty was up, the hot logic box and fan stopped working. Because it was out of warranty, we had to have them replaced as well as the valve, at our cost - very expensive! Within a week of replacing the box and fan we noticed water pouring out of the tank. That was it - the whole system needed replacing. I was very upset. I called Dux and was told their new improved systems will last longer. I was furious! After an initial outlay of over $2,000 AND the expensive repairs I w...ould have expected it to last much longer than 5 years! I made a few phone calls, including the Office of Fair Trading. I called Dux back and told them this was unacceptable and I would be taking the matter further. I also told Dux how their own representative had told me on the phone that these systems only last about 5 years. I certainly wasn't told THAT piece of information when I purchased it! A few minutes later I received a phone call from someone higher up at Dux. This person told me that Dux would replace the system at no charge but without a further warranty. I believe this only occurred because I had been in touch with OFT. The system was replaced within days. In 2015 we had to replace the logic box AGAIN. It's now December 2018 and yesterday we had to replace the box and fan. 24 hours later still no hot water. The system needs further repairs which could cost upward of $1,000. In total there has been close on $8,000 spent since 2007. The money saved on power bills does not balance this out. The reason I purchased a heat pump in the first place was to do my part in being "greener" and contributing to saving the planet - something I take very seriously. But does the landfill cost to dispose of these 5 year units outway the fossil fuel cost to the planet? I could get 15 to 20 years out of a simple electric hotwater system I could purchase for around $1,000. We only need one for 2 people. We would dearly love to install a system that doesn't rely on fossil fuel, but as pensioners we can't afford to take another financial risk. It was hard enough on a pension in the first place but we felt good doing our bit for Mother Earth. After 4 days without hot water I'm a little upset! Please, do your research when it comes to these systems, read these forums and feedbacks and make your decision wisely! One good thing that's come out of all this is we've made very good friends with our outstanding plumber!
Nothing but trouble in the beginning and bigger trouble in the end! one dead unit and 5 years old! A
Awesome to start with and then 2 visits from appliance person; finally called plumber to have another brand installed and he said "Stay away from heat pump!"
I have another brand which is so far so good after almost 5 years - plumber did not know about that brand which is probably a good indicator.
Just waiting for my other dux heat pumps to implode at my other rental properties - very bad technology which did not work as planned! Dux should be ashamed of themselves and assisted the people who purchased these units which turned out or (will turn out ) to be DUDS!

After two failures through leaking tanks - never again will we buy a Dux product
Everyone deserves a second chance but when the same thing happens again and the company doesn't back it's product, it is time to take action. I am interested in a class action. I stripped down the replacement unit and it appears to me that the leak has been present for a long time. It did not become apparent externally as Dux have gone to great pains to seal around the cylinder which stops the leak showing for months or maybe even years. I am going to get a professional engineer's opinion.
Questions & Answers
I have noticed the fan has not been working for some time but water seems to be the same. Has never been too hot and only other problem I have had with it was when it kept icing up and turned out to be a stuck relief valve.
