Crap. gas never switches over need to manually reset. ie any time there is clouds after a few days sun. Also 1yr warranty on a system with a 5 yr payback! completely not working now after less than 3 yrs use. had the heater unit swapped out after 6 months (luckily within warranty). Would never buy another dux.
Only one year Warranty on parts on an expensive sophisticated hot water system?
How do companies get away with only one year warranty on parts for an item that's more expensive than my ducted heating which i get about three years warranty on? Why do consumer affairs allow Dux to only grant one year warranty on parts when apple phones you use every minute of the day has 2 yrs warranty on half the price?
I believe a class action should be done to remedy customers issues such as, paying higher bills for water, gas and electricity because of faulty hot water system. Of course you can also add labour and parts cost to the reme...
Cheap rubbish and panels cant handle frosty mornings burst
11 Years old and had value replacement last January for water leaking and fixed, now had worst frosty mornings this winter bring more leak from solar panels its not the value this time. So break down in frosty mornings of -3c and -2.2c two days row then started leaking from Panels. Now get repairs, hard to say need new panels.
simply i prefer buying products made in china than this money costing machine.
costing a lot to maintain, breaking itself one by one almost every months and costing around $500 each time and the product is disgrace i feel sorry dux is australian company
never buy again for sure if you are looking for one just skip this brand
Costing me more than saving!!
I have a Dux DN15DS Boosted Gas Solar Water Heater. It is only 3 three years old and have had to get the pressure relief valve replaced 3 times since we moved in. So much water has gone down the drain either from leaking from the panels on the roof and coming from the pipe next to the tank. I've woken up again this morning to the sound of water gushing out of the pipe again. My water bills are through the roof because of this system. Now we have to wait until a plumber comes out again to tell me what the problem is this time. They've told me in the past to get rid of this hot and replace it with an electric/gas instantaneous unit. This unit just keeps costing me money. What can be done to get this fixed once and for all?
Had the unit for 5 years old and already broken for four times. Customer service also terrible. And after the warranty their approved service companies are terrible too. Very unhappy about Dux company. Not recommend for anyone. Try Rennai. Heard that brand is good. Also the off flow valve is leaking all the time. Replaced three times for the past 5 years.
- Sunpro DN15DS (Storage Tank, Natural Gas)
- Verified purchase
Terrible - Avoid
My Hot water service is almost 3 years old and has just broken down for the second time.
There are no local service agents in my area.
Because it's out of the 1 year warranty Dux doesn't want to hear about it.
All the local plumbers say the same thing: "Dux products are cheap rubbish - you'd be better-off getting a different system rather than repairing it".
Avoid these Products!
- Inferior Quality
- Bad Customer Service
- Bad Service Network
- Inferior warranty (1 year, instead of the standard 3 year)
What a dud will never buy this brand again
I don't think I've had a year that this system hasn't cost me hundreds of dollars in repairs and water loss..from leaks from solar panels on roof to pilot light being faulty to solarnoid faults...it cost me a lot to buy regretted it ever since...completely unhappy despite complaints nothing happens
Poor product and service
Our solar hot water service wasn't working and needed parts replaced including diverter valve when we moved in to our house two years ago. As the house had been used as a display, the system hadn't had much use. We were without hot water for over a week and Dux were difficult to deal with, but after much stress finally covered the repairs. It is now two years later and the diverter valve has been replaced again. It was causing electricity to turn off due to water leakage from broken seal. The system is only four years old and we are not at all ...confident with the product. The tank is also rusting and top has buckled but Dux did not want to know about these issues, stating it is not affecting function of system. We are not alone when reading other feedback. The company should compensate owners for this poorly performing product.
Panels installed 2008. Failed & replaced 2011. Failed & replaced again 2017.
The performance of the system has been very good, with nearly zero hot water bill annually. No probs with the storage heater & pump or the technology. However the Dux 2AP absorber panel tubing corrodes & leaks internally - perhaps due to our proximity to the ocean & the essential breather vent in each panel. The cost option of changing brands is obviously prohibitive. Now replaced twice. As the panels cost upward of $800 each and re-installation is $500 per occasion, much of our energy bill saving has been eroded by poor quality components.
i don't like our sunpro solar gas heater. after just 4 years, we had to replace pump part and new one now makes so much noise. it is like a thumping noise when having a bath. so much for enjoying a bath.
we are told now that such products are not suited for areas where temp gets to zero; like Albury Wodonga.
basically we had to tun off and then turn on heater for years before it finally stopped working altogether.
on top of that, the plumber sunpro recommended to us, charged us over $400 for a part which i could have purchased myself for $234.
Need a full system replacement at 8 years. Rubbish product.
After having the regulator replaced at about 4 years old, and other issues, the tank has burst at 8 years and there is no replacement tank to allow us to continue using the existing panels. Terrible environmental waste. Woyldbt be so disgusted if I could replace the tank. Do not recommend DUX.
The frost valve for the solar panels fails every year despite it not being winter with much loss and waste of water. $450 cost each time to replace. The main unit - water storage tank on side of house also malfunctioned. Even though under warranty it still cost $750 for second installation. That one did not work either. So really expensive yearly replacement costs. Not cost efficient.
worst product. dux shrugging off their responsibility
Dux DN15CS has to be one of the dodgiest product sold to Australian consumers hands down. This unit has given us nothing but trouble over the last 4 years and they are refusing to fix the issue as they claim it is outside the warranty. We have had more than 6-7 call outs over the last 4 years as the system would either not work or spew too much water through "plumb to waste" or a dodgy valve of some sort. On a hot summer day you would expect 20 to 30 litres of water going down the drain due to this substandard product, and to add the misery the...machine will then stop working all together. We had to ring their technician to come and fix the issue and same thing would happen again few months later. I am not a plumber and claim no expertise in the field of plumbing or solar, however I think their product hasn'% been tested well and long enough and doesn't suit melbourne weather which can fluctuate from extreme day heat in summer to cold winter nights. The repaired who was initially sent by Dux suggested to turn the machine on and off at the switch if the problem persisted and we had resorted to doing the same when the machine didn't work and now it doesn't work at all even if I were to try switching the machine on and off at the main switch. their call centre is very unhelpful and are always trying to shrug off their responsibility and always asking for credit card details in case it was not issue covered under warranty. we always had to be very persistent with them and it had always been incredibly difficult. and now they are refusing to repair the machine all together and saying we should contact their preferred repairer. Products sold under Australian consumer law is expected to perform upto certain standard regardless what it says under warranty. We asked them to replace the machine with something that is fit for the purpose when it was still under their claimed warranty and they refused and now we have this junk just sitting there spewing out water like crazy while we are forces to take cold shower. we will be taking this up with consumer rights victoria. I understand we might not be the only consumer facing this plight so May also consider class action.
Another disappointed customer
I am extremely disappointed with the Dux sunpro solar water heater. I have had the system approx 6 years.
2 months after the warranty ran out one of the 3 panels started to leak.. I removed the panel thinking 2 will be enough but after another few months the 2nd panel started to leak.
I have decommissioned the system altogether especially when I was told the panels are $1400 plus labour to replace. I have rang Dux to talk about some sort of compensation or repair but they are not interested.
Don't waste your money go elsewhere.
We have had issues with the Dux Sunpro gas boosted solar hot water heater since moving into a newly built home 2 years ago. We have found it to be unreliable and frustrating, one day it works and the next it doesn't. It was repaired under warranty. But in the past 9 months it has continually stopped working. The Dux recommended Technician has had trouble trying to work out what the problem is, as hard as he has tried! Are Dux providing enough technical training and support for their local service technicians? Our contact with Dux customer serv...ice has been less than satisfactory. We are waiting for our local technician to call us back, while he is trying to work with Dux to resolve the problem. We have had unreliable hot water for at least 9 months and now no hot water at all for the past 4 days and no idea when we will have!! If we have to buy another hot water service, we will be doing a lot of research and it definitely won't be a Dux.
Unit has functioned perfectly for 5 years. First service cost $150, nothing major was required other than slight thermostat adjustment the unit is in perfect condition. The unit is housed indoors and has never gone wrong since it was installed. Call out for service was arranged from the internet, received a callback the next day and the day after that the unit was serviced.
Avoid at all costs. Try any other solar product except Dux
Avoid at all costs. My unit is just 12 months old and has the diverter valve replaced at least 4 times in 12 months. Don't try to call their customer support(sic) as they don't want to know or even listen, So now we are pursuing Consumer affairs and legal advice. Once again steer clear of this product and I think 1 star is still to high for this woeful product.
Best investment I have made.
We have had the 400 litre Electric Boosted Sunpro with 3 panels on our roof now for almost 10 years.
We have not had one single ounce of trouble. Our hot water basically costs us nothing, except for the service availability charge and the odd time we have to turn on the booster during extended periods of rain. It is serviced yearly and we are now due for a new anode. I don't know why anybody would go gas boosted. Off peak electric or time of use electric to me is the best way to go.
Our system was installed by a competent plumber and electri...
Diverter valve broke after 3 years
We moved into our brand new house by Burbank 3years ago now. The dux Pre Boosted Gas Solar Water Heater MP15 came with the package. Diverter valve broke and got replaced costing AUD 450. We previously had a Bosch continuous hot water system at the old house and it never broke in the 11 years that we were living there. The warranty on the diverter valve is 3 months ... if something breaks again, I'll be scrapping the dux for a Bosch!

I have a Dux 4F136S 415lt tank with 3 solar panel, built 6/2009 so over 10 years old and just started leaking. Can a new tank only be purchased? We’ve been very happy with the system an think 10 years from the tank is what should be expected.
Thanks for your inquiry Mick.
The replacement tank is a 400DPM36, this is a dedicated solar tank with sensors, controller and pump built on at the factory, it also includes a solar Tempering valve.
Let us know if you need some help identifying where to buy one.

We have a hotlogic box which is flashing red on the output. We have to turn the unit off to restart the unit. We have to restart the unit every night. Is this a simple fix?? Has a sensor gone?
