Dux Airoheat D2FH00000C

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...Read more

Dux Airoheat Heat Pump Review

19/02/2018

This is a review I just added to ieatwords.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 ...Read more

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...Read more

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...Read more

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...Read more

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...Read more

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...Read more

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...Read more

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...Read more

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...Read more
