Extremely disappointed, Efflorescence in the Solar Panels on two Homes Dux not intereseted
As a Design and Build Company, we are very disappointed with Dux Solar Hotwater Systems. We had a number of Solar Hotwater Systems installed on Projects for the last 15 years with little to no problems until we started using the Dux system. We have large areas visible from the road of white efflorescence buildup within the panels the projects were built 3 and 4 years ago. Advice from Dux is that they only warrant the panels if they leak.
Hopefully, Dux will change their position on their refusal to address this issue as it presents their product in a very poor light.
Stay away from this company
Hi well l certainly wish we had seen this forum before wasting our money on this useless product. We have had problems almost from day one, people came out while it was under warranty but did not warn us this would be an ongoing situation. We have had our frost valve replaced three times in three and a half years and it's playing up again, just a few weeks after being replaced. As with everyone else we have had no satisfaction from the company. I actually find it amusing that they are paying customer service people at all they could save th...emselves a fortune since nobody is getting ANY THING CLOSE TO SERVICE. From the replies some people have received the company is well aware that there is a MAJOR problem, and yet not only are they unwilling to rectify our problem but none of our state consumer affairs departments are doing anything to stop them selling a faulty product or helping us to get them to fix what is obviously VERY WRONG! !!! I thought it was against the law to sell a product not fit for purpose. All we can hope for the future is that prospective customers read our stories and DON'T buy from this company. I know a lot of people have asked us what make of solar hot water system we have and l warn them to steer clear of this company, for ANY PRODUCT as they are not interested in their customers at all.
Frustrated Dux Solar Hot Water Owner
We had a Dux Sunpro Gas Continuous Solar Hot water system installed in February 2010. It worked well for around 5 years before we started having troubles (just out of warranty).The Gas would not ignite and heat up the water when there was insufficient Sun. We phoned Dux and they advised us to call the local plumber who service Dux systems in our area. We had the plumber come out and they said that it looks like it is a tempering valve issue. We had this replaced at a total cost of $449. A friend of mine who is a plumber but does not specialise...in Solar Hot water systems said that it would not be a tempering valve issue as this has nothing to do with the ignition of the gas. We then phoned Dux and explained the above, they said that they would send a technician out from Dux. The technician came out and checked the system. He said that the tempering valve had been set incorrectly however that would not affect the ignition of the gas. He was unsure as to what the problem was. The hot water worked for a day or two after he had come out then stopped working again. We then phoned Dux and they spoke to the technician who said that it is probably a PCB Computer Board issue. Dux advised us that to replace this it would cost a further $334 for parts and labour. The technician is coming out tomorrow to replace the PCB Computer Board. If this does not work we will be extremely upset. We have had no hot water for a number of weeks, very frustrating especially with young children. We are very unhappy with the performance of the system and the extra money being spent, we would not recommend this product to anyone. We will be contacting the ACCC for guidance as it does not appear to be an isolated issue judging by other people's experiences.
Dux frost valve fails again! Avoid this company!
We purchased a solar electricity/hot water system through Origin on the 3rd of June 2011. The system had some initial problems however these were ironed out fairly quickly by Origin. It wasn't until almost 3 years later that the first problem occurred. In February 2014 we noticed that water was pouring out of the frost valve into our gutters, which also resulted in us receiving a higher than average water bill for that period. When we arranged for a call out to have this fixed we were told that the frost valve had failed and had to be replaced....$357 later we no longer had water pouring out of the frost valve and I when O asked the technician how often these parts needed to be replaced I was given a vague answer of anywhere up to 3 years. Here we are 16 months later and the same fault has occurred. We've just had Dux send someone out and sure enough, the Caleffi 603040 frost valve has failed again, this time in just over a year. $275 later it's been replaced again and the service technician told me that these particular valves fail regularly and when he has asked Dux what is going on with them he has just been advised that they are faulty. He's advised that most people once they are out of the warranty period simply remove the frost valve and cap them off as here in South East Queensland we rarely reach temperatures where the valve needs to operate. According to the specs on the Caleffi website the 603040 has an opening temperature: 3°C and a closing temperature: 4°C. Considering the lowest recorded temperature in my suburb is 4.9 degrees C the valve should never have opened in the first place. Not impressed that we've forked out $632 in just over a year to replace the same small brass valve I called Dux to explain the history on our system and query why we've had to pay for the valve to be replaced again within such a short timeframe. Predictably, I was given the same stonewall 'this is your problem not ours and it's not under warranty so we're not interested' response that so many people on this forum have received. I explained that the valve shouldn't have needed to open as we don't get down to the temperature required, however the person that I just spoke to at Dux probably had no idea what I was talking about and certainly wasn't interested in doing anything but talking over the top of me to tell me that this isn't under warranty. When I advised that the service person said that there appears to be a problem with the actual part they are using, I was accused of lying and told that there are very few problems with this part. A cursory glance at the first page of this forum alone shows that this is, to put it generously, incorrect, and that's without going into the numerous problems also listed on Whirlpool.net.au! So Dux has again lived up to it's reputation. Thanks for nothing Dux, your 'customer service' team has again reinforced the impression that they have no interest in either customers or service.
Questions & Answers
We have a sunpro prodigy 3 and its only 7 years old we have had to change the frost valve twice already. Last week city west water rang and said we are using 1900 litres a day so i checked everywhere and found that its the frost valve running like crazy at night again. I cant afford to keep replacing it is there anything else i can do??
Hi Peter, It is very unfortunate that the frost valves have failed twice in the 7 years. In many areas of Australia it is required to have a frost valve installed on your solar collectors. What state do you live in? If you would like to discuss further please call 1300 365 115 - option 2. Regards Dux After Sales.
