Worst hot water system ever! Broken just after 5 year warranty!

published

Worst system! Not having enough hot water to use 2 showers at once. Problem starts after 3 years and now just after 5 years, there is no hot water at all. It happened to many other people that have the unit installed in 2013. No wonder the product is now discontinued. Dux does not take responsibility. I have contacted ACCC about this.

works great but persistant breakdowns

published

Had this unit for 7 years now and have had persistant problems new house built by Burbank. DAY 1 no hot water service callout and finally fixed. From then on it worked well until 2 yrs and electronic controller died 650 $$$$ and out of warranty as with previous comments its all on your own back now several breakdowns since then and a very sympathetic plumber who has a serious dislike of the brand looked after us each time with no charge sometimes as in the area and was a quick fix but the inconvenience of breakdowns make it a poor choice of unit it has now gone again and think this will be the last

Very bad product and customer service

published

Burbank has installed this product at our property in Aug 2013. We had hot water problem already 3 times in 6 years. Now, again on 14/06/2019 hot water stopped and when I called company - guess what - the girl on the other side started saying it's out of warranty instead discussing the problem or offering some guidance or help to get it fixed.
Hope, management will check how customer service people are dealing with the customers.

Worst hot water service on the market!!!

published

I would not recommend this product to anyone. My partner and myself purchased a new house 2 years ago which came with a sunpro unit and have had nothing but problems with it spewing out water. After calling dux and being told that a 3 year old unit is not under warranty it cost me $400 for a new diverter valve. The plumber also shook his head when he seen I had a sunpro unit and said that they are a bottom end product and to get rid of it as soon as I can.

Problems From Day one

published

HWS was not working before I moved into my new McDonald Jones Home in October 2015. Plumber blamed electrician, electrician blamed the solar panel installer. Anyway eventually was working.
I don't seem to have any problems until cloudy or wet days then little or no hot water. I have had technicians out now 4 times the last only being 3 days ago and he said the unit is faulty and we should purchase a new one.
I am still without hot water and just waiting for a sunny day to hopefully get some hot water. I'm not in a position to buy a new HWS at the moment. Quoted $2000 for a replacement.

Not working properly

I installed this system in my home 4 years ago through Mac Donald jones Homes and each winter I have cold water and am unable to shower or wash dishes of an evening.We experienced this issue in the first year several times and technicians came and fixed and changed different parts many times but the issues remains same.Then they changed whole unit and was working fine.Now the problem is not hot water if it is cloudy.Sometimes if we turn off and on the the power switch it will start and hot water will be there for while.Sometimes it doesn’t work.Dux system is a water cooler.

It is that time of the year again where the dux cools the water during the day!

published

I purchased my home 4 years ago and each winter I have cold water and am unable to shower or wash dishes of an evening. It seems that the water pump just cools the water down during the day. Electric boost of a night means I can shower in hot water morning only! Each year I get the system looked at and am told it works fine. My last house had a Solarhart, it was a fantastic system and the water would only be cold if I had 2 cloudy days. Dux system is a water cooler.

Do not buy a Dux Sunpro Solar system!

published

Within 11 years we need to replace the 315 litre tank for the 3rd time. 5 years ago the first tank was replaced after threating to shame them in providing a replacement. Now the tank is leaking again and water is coming out around the side inspection cover. After contacting Dux they will not replace it, will cost approx $2500 to replace. They Market a 5 year warranty. They should say their product will last 5 years. To replace the whole system with another manufacture will cost $7000 plus. Don't buy a Dux you will be sorry, I have contacted the Dept of Fair Trading and hopefully they can do something.

We wasted our hard earned money

published

In 2013 we had a Sunpro solar hot water system installed in our newly built house. Within 3 and a half years the collector tubes under the glass panels started to corrode. As the system was still under warranty I contacted Dux but was told by the receptionist to send photos of the problem. I sent the photos to them but was told that they would not do anything unless the system was leaking even though there was a five year warranty. I have kept all the correspondence which I had with Dux, including photos.This company should be discredited in selling a really bad product. The corrosion is really bad now and it is out of warranty, I fear that at any time it will cease to function. Stay away from Dux.

So what you are saying is that the corrosion will not eat into the pipes and cause a problem i.e. water leakage etc. during the life of these panels????

Total Garbage

published

We installed this unit just 4 months back after our old unit started giving problems. In the first week, water started gushing out from the opening at the top of the unit and now the sensor has stopped working. We have been without hot water for almost one week. I called Dux and the reply given by their customer service person was that I am not the only one without hot water. Dux does not care about their customers. Their customer service people are rude. They are insensitive to the needs of their customers. Never buy a dux product.

Useless crap!!!!! stay well away!!!!!

published

We had this unit installed at our new home. Worked fine for about 18 months, but it blew the joining pipe between the 2 panels- the pipes coming out of the panels are very short not much room for the olive ring to seal on!!! Now just as we are coming into winter this year, I now notice our frost valve is leaking even though the temps around 10 degrees. Bought a new one & installed but its still opening to early.....need to investigate more.
I think the money I spent on the solar hot water system would have been better spent on a basic hws & solar power system & let it pay for the heating during the day!!!!

Awful Company, Useless Product

published

5 years on from installation, and the system is not working again. Gas booster won't ignite. As the last 3 times it's been repaired have been diverter valves, I can safely assume that this will be the problem again. First three repairs were under warranty, last one was on us. Most unreliable product I've ever come across and trying to get a plumber in my area to service this system is almost impossible. I honestly don't know how Dux could sell these.

GDAY Michael
I'm only guessing but I think you would have to get a plumber to bypass the panels
Have you asked the company doing the service?
Good luck

Hi Michael,

Thanks for raising this question.

You will be able to get limited hot water via element. Your plumber will need to disconnect the flow and return lines to the collectors at the tank, power off the solar module (this is the controller and pump) and you will have 1/2 the tank capacity available by element as it is located 1/2 way up the tank. You will need to take that into consideration, only 157L will be available at a time via element.

Best Regards,

The Dux Team

I have a solar gas sunpro system how do I turn the temperature up in it. Thanks you

Gday Peter have you got a manual for the system?, if not try downloading one from the internet.
This may tell you. However, all hot water systems are now fitted with tempering valves which mix the hot water from the system with cold to give water at a controlled safe temperature i.e. not scalding hot. This may be playing up, get it checked by a local plumber perhaps. Otherwise the system may not be working. If you read previous posts I described how to find out what controller your system uses and how to download a manual for this. Hopefully the controller has a diagnostic system built in which will show you what is happening, but you need the manual for the controller to do this.
Otherwise you can check that the gas booster is working by turning on a hot tap and seeing if the booster fires up. This is clear because hot exhaust gas will come out the exhaust on the front pf the booster.
Check that you are getting some solar gain from the roof panels by carefully touching the copper pipe from the tank to the pump, this comes down from the roof and into the side of the control box on the front of the main tank. If its sunny this should be warm to hot and you can feel the pump vibrating slightly.
If it's been sunny for a while the main tank should be at a significantly higher temperature than the ambient air, check this by carefully touching the hot water supply pipe to the booster at the top of the tank, it should be quite warm to hot.
HTH
Cheers

Hi Peter,

Thanks for raising your question.

The temperature of the system is fixed and not adjustable. There is a Tempering Valve downstream of the system (orange-capped valve) that will need to be cleaned and serviced or replaced by your plumber.

Please let us know at help@dux.com.au if we can help you further.

Regards,

Just in the last couple of weeks there has been low pressure from the hot water tap (system) seems to surge a little bit. We have good cold water pressure. I have checked the hot logic controller, power led green, sensors led green, outputs led off.
Any thoughts as to what the issue is
