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????

How much more bad publicity does Dux need before they bite the bullet and FIX some of these outstanding issues. Mac


Another disappointed customer

published

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.

Major failing after a relatively short period of time

Do yourself a favour and stay clear of Dux

published

Purchased complete Dux solar hot water system just over 6 years ago at significant cost. Thought I was buying a good product (from a reputable company) that would last at least 15 years but tank split a year after warranty expired and Dux did not want to provide any solution, even though the plumber who inspected the tank said that Dux now provides a seven year warranty on their tanks. Plumber said they no longer deal with Dux as have had similar experiences. Be warned!


Trouble, trouble and trouble

I have Dux Sunpro for 6 years, every winter time, we sort of hot water for shower, we have 3 people in our family.
We live in NSW and I had 400 litter hot water tank.
Every year we have at least one or two problem with this hot water system?
Whether too cool, not enough hot water use, a few raining day not enough hot water for use, now my solar heat part not heat, a few time electrical part burn in 6 years time.

Do Not Get A Dux. My Unit Has Just Burst For The Second Time In 7 Years - No Warranty

published

I have an Electric Boost Solar HWS (Sunpro). 4F136S. The first unit burst after 2 years and the replacement unit has burst after a further 5 years. Dux are not the least bit interested that I have to replace 2 units within 7 years out of warranty. I sought a review from the After Sales Support Team and feedback and they offered no help at all.
My advice to all is DO NOT get a DUX.
Very disappointing.

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.

Hi Mick,

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.

Hi Rod,

Thanks for providing the details and raising the question.

There are no precise figures available on the running costs of an electric boosted solar water heater as there are too many variables.

Factors such as the location of the system, the orientation and pitch of the collectors, variations in UV radiation (which is what provides the heat input), hot water usage patterns as well as what is charged per kW/hr by your energy provider meant that even an average kW figure per day is difficult to give.

As the tank is boosted for 1/2 the storage volume only, worst case scenario there is little to zero UV input and the boosted volume of 200L is used in a 24hr period, 11.6 kW of energy will be consume heating up that volume to 60 Deg

Cheers,

The Dux Team
