very loud unit
we had this unit installed some years ago and now it has very very excessive noise the unit is still operating but it is getting louder by the day we are waiting for it to stop operating i do not know if it is a faulty bearing or what
Purchased in September 2013 at from plumber for $500.00.
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........
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!
This dux airoheat System is the worst system
The water system came with the house we purchased 18 month ago. It was fine to start of with, then it started leaking water out of the very bottom, the condenser wouldn’t stop working. We had a plumber come and look at it, he cleared the valves and serviced it and said that maybe it could be the extreme humidity we have. It was going ok the water leakage stopped somewhat for a month and it started again and I noticed some jelly brown stuff leaking. Trying to ring dux itself didn’t achieve anything, they didn’t want to know about they own hot wa...ter system. Again I called a plumber he checked it out and said it, this system is cactus. By now it was just loosing water constantly and would need a new tank, which would cost more than a basic hot water system. I can only say to anyone don’t buy anything from DUX they systems are not good, they after purchase service is the pit and staff is rude. Only today while looking at other reviews and while doing mine I found out this airoheat systems are discontinued which is good as people are just being ripped of by buying one. We feel so very disappointed:(
Buyer Beware Dux Airoheat Heat Pump Review
Dux Airoheat Heat Pump Review
This is a review I just added to productreview.com.au for the Dux Airoheat Pump.
Buyer beware this could happen to you! Do not waste your money purchasing the Dux Airoheat Pump as I discovered the hard way. In 2008 when I had my house built, QLD government legislation required all new houses to have an energy efficiency rating hence the requirement to purchase an energy efficient hot water system i.e. Dux Heat Pump costing $3700. Since installation in November 2008 by a professional plumber ...and electrician the Dux Airoheat Heat Pump has failed three times with 2 blown heating fans costing over $300 for each repair via electrician installation. The second heating fan was replaced in April 2017 by the Dux authorised service agent who inspected the system. Note I also had the 5-year manufacture service as per the Dux Airoheat Pump manual. The third major failure occurred on 10th February 2017 during the night with the element seal failing causing a massive water leak inside the metal jacket of the Dux Airoheat Pump as per the emergency plumber’s report. Due to the Dux Airoheat Pump element seal failure this caused water to be forced back up through the electrical conduit that wraps around the bottom of the tanks exterior and through the rear concrete block exterior house wall into the internal wall cavity of my residence causing significant flooding to the lounge, kitchen, laundry, pantry, hall and one bedroom. Suncorp Insurance estimates in excess of $10,000 damage to flooring, walls and cabinets of my residence. Note as the damage to my residence was caused by the Dux Airoheat Pump I cannot claim the cost of the heat pump with this claim or the new electric hot water system I had to install.

- Sold as a premium product alternative
- Spurred on by the potential energy and $$ savings from switching from an all electric system
The Dux didn't improve $$ savings all that much though was good for government rebates. Our household was a 3 person household with regular domestic use and our unit died in just under 7 years. The number of negative reviews shows Dux engineers its products to fail and is an indication of their engineering standards of Dux products.
Far from innovative, probably overpriced. Our family will exhaust all alternatives before returning to Dux.
There are 2 aluminum annodes in the Airoheats that offer good protection to the tank, but I suggest the tanks be flushed through the element port every 3-4 years depending on water quality. I work on these regularly and have seen some pretty scary looking jelly / toothpaste like stuff come out when flushing. Unfortunately its nearly impossible to replace the annodes, and thats most likely why they installed 2. These days when the Hot logic or fan dies (usually due to exposure to weather), we simply install a regular thermostat and 2.4kw element...at a cost of around $200. Sure your power bill will increase slightly, but you will have a very reliable HWS. The tanks I found to be good quality with only 1 having sprung a leak in 8 years. For the money (after rebates that were offered at the time) I think they were ok.
Jelly like Substance in the Tank
Our Dux Areoheat started leaking from the base of the tank last week-end.(7 years old). Our plumber replaced it with a new system yesterday.When draining the tank we found it was full of a jelly like substance.Does anyone know what this substance is and if it harmful.I have kept some of the substance for testing. Dux seem to be ducking for cover when others have had the same problem.
Do not buy!
First unit installed in 2009, broke down during the Christmas holidays barely 8 months old. Compressor would not start hence no heat and PTR valve would leak constantly (I measured it at about 2 liters an hour). Dux sent a plumber within 48 hours (good service) who installed a conventional heating element but didn't address the leaking PTR valve spilling close to 50 liters of hot water in to the backyard every day on peak tariff (bad service).
Over a period of three weeks it took 21 phone calls (worse service) all the way up to the NSW state m...
This thing is a piece of junk, Then trying to get it fixed is worse, Dux have very cleverly found a way of been any assistance what so ever. It will be the fourth time in 9 years there has been an issue, this time it is the fan blown again for the third time. Thanks a lot for the great customer support.

Dux AiroHeat Pump hot water system
We have had trouble with our cold taps for a number of years with only some taps blocking and having a jelly separated substance and grit in the system. It only happens when the cold taps are run and not the hot taps so we did not think it could be the hot water system. I have had water experts out to check and even had the water tested and it came back with exceptional dangerous high levels of Aluminium in the water tested. Finally today our plumber was speaking with another colleague and he told us about the problem with this jelly like sub...stance in the DUX AIROHEAT SYSTEM! Our drinking water has been continual compromised and contaminated and DUX does not want to take any responsibility for its pour manufacturing of this product. I understand why the product has been discontinued!! Samsung took responsibility for a phone that was not up to scratch now it's your turn DUX! Our plumber has been told today on the phone that it is out of warranty so not their responsibility. MANUFACTURING FAULTS and BAD DESIGN should always be the responsibility of the company producing the product!!! What will you do DUX?
It's a lemon
I had initial problems because I live in Canberra and I was assured by Dux it would work down here in the cold.
It failed immediately as did over 100 delivered in Canberra in 2008. The hot logic box was not installed so they put in an element to mains while they fitted the correct chip. They then lost the bung where the element was so they left the element in and it has corroded the housing. Dux refuse to accept any liability for this even though they selected the technician. When the plumber tried to repair leaks last year all this white muck...
Extremely disappointed pensioners
Disappointed that this hot water service is not repairable after just 7 years. It was extremely noisy when heating. Previous hws systems have lasted approximately 16 yrs each. Would never buy another Dux product. As pensioners it is an extra expense we did not need at this stage. It was supposed to be government approved new heat technology and good for the environment but is a big let down !!!!
We purchased a Dux Airoheat 5 years ago at a price of $3850. This was a very expensive hot water heater. Un fortunately it lasted a mere 3 years before it completely packed up. A brand new one was installed, ( of which we still had to pay for the installation of $440 as by Dux regulations this wasn't a part of the 5 year warrantee. This one is now 4 years old, and is leaking from beneath somewhere. We contacted Dux, as this hasnt reached the 5 year warrantee as yet. ONLY to be informed that it is not under warrantee anymore, as the Warrantee st...arted from the date of the first unit. For 2 very expensive units to pack up under the 5 years, I think is totally unacceptable. Dux products are not good, and I would not recommend them at all. The customer service was also appalling.
Very poor quality, buy at own risk
Came with the new house we moved into and like most of the fitting we got it was cheap & nasty as well. Started having problems from the start, heat pump kept shorting out in the logic box, warranty job twice within the first 12 months. Fan motors also have issues according to the sparky but we have been lucky there. The system would trip at drop of at hat, we seemed to be regularly turning it back on at the switch board. After 3 years started leaking from under the heat pump shroud. Tried numerous fixes but corrosion in the water collection pa...n from the heat pump unit but sparky said we were on borrowed time. Gave up just resigned to seeing how long we could get out of the unit. 6 years in the end before it finally gave up. Absolutely woeful lifetime IMO. Even though I had no control over this purchase, I would definitely avoid this brand in the future. All the sparkies that looked at it didn't have anything good to say about the brand which says something as well....
Within one year of installing this system the hot logic box failed. Luckily at that time it was replaced under warranty. Within another year it has failed again. Dux's recommended repairer came out and told us that it was the fan - paid him $290 to replace it only to have the same problem continue the next day. Then he informs us that the hot logic box has failed again. This time Dux will not cover under warranty as we did not purchase the part. First I've heard of a company not covering their own parts under warranty for at least 12 months. I wouldn't bother buying one of these again and I'm not impressed with the level of service from Dux.
Faulty product with no support from Dux
The Dux Aero Heat hot water system we purchased just over 5 years ago has been a complete failure. The logic controller has been replaced twice and the fan twice. The circuitry for the 'outdoor system' required after sale water proofing.
Now the safety switch repeatedly trips due another problem with the hot water system, and a brown oily substance is leaking out of the top of the unit. No hot water yet again. More inconvenience due to a substandard product.
Dux just don't get that there is a 'reasonable expectation of performance...' for this product. This product does not meet any reasonable expectation, nor does it meet the most minimal level of expectations. Purchasers of these Dux Aero Heat systems that are substandard, need to contact ACCC Complaints and Problems, Electrical Safety Office, Office of Industrial Relations ( in your state), national media and as a previous comment perhaps, class action then we may get some assistance from Dux.
Terrible cost me more money in repairs than it has saved me on energy
Had this unit installed n my brand new house, died 3 months outside the manufactures warranty, $600 for new computer ( 240v supply terminal block was double sided taped to the inside of the control box tape gave way and it shorted out and fried the computer / control board, called Dux and they wouldn't come to the party with warranty. now 18 months later unit has stopped working again no lights at all so most likely the same issue again. $180 to get a plumber out to look at it then parts and labour on top. Think I will just swap to a different brand solar unit.
Poor service on a poor product, do your self a favour and don't buy a Dux heat pump !!!
P,s I have checked the electrical circuit and that is fine.
Dux is bottom of the class
I have also had a terrible experience with this product
The water pump was purchased on 15/04/2009
The product has failed in the followign ways:
1) Shortly after the warrantly expired I had no hot water and had the unit repaired at significant cost because the outside unit was not waterproof and a major electrical component failed due to water damage! The service desk said I could not escalate the matter to anyone when I enquired as to why a unit designed to be outside failed due to water damage
2) The unit again failed to produce hot wate...
bad for your health
after paying a lot money for our heatpump which imploded ten months out of the five year warranty. Dux said sorry can't help. we first noticed a yellowish tinge in our hot water which became worst so a plumber drained the tank out, shock horror all this gunk like a thick jelly and oil came out from the condensor or heat exchanger which must have corroded out releasing this muck into water that we drink,shower,wash up in brush your teeth, now our taps and shower head dont work. just what has this done to our HEALTH? PS I would like to add some photo's to show you the stuff that came out.
