My Dux Radiant 250L, has begun leaking badly just over 5 years after installation. It's installed in a holiday home and has been quietly leaking like a sieve for quite sometime apparently, causing the heater to run continuously. So I now have the triple hit of a new HW service required plus larger water and electricity bills, not even sure for how long. It's only a couple of months out of warranty!!! Replacement cost including installation, over $4000. Thankyou very much. Yes Dux Sux. :(

I have a 250 Ltr unit installed which has never performed. It consistently gets cold by the third shower and sometimes randomly for no reason. It seems also expensive to run even though it is touted as efficient. Annual running cost is in vicinity of $800 which for only 2 people doesn't seem to add up. Only response I have had from Dux is to get a technician look at it, but nothing found. I am now looking at other options as am over trying to solve. Dux will not be on my next shopping list.

Within 7 years I have spent $960 for the repair of the water heater for a defective "Logic". The company refuses to comply with the competition and consumers guarantee. I cannot wait to get rid of that product which is of unacceptable quality and take them to court. I would not recommend this product to anyone who thinks that buying "local" is supporting our manufacturers.

After just 2.5yrs in our brand new home our Dux hot water systems "hot logic" controller has partially died. The external fan motor gets hot but will not start. I have to manually "flick" the fan to get it to run otherwise no hot water. Surprise surprise. .... Dux tell me it's not covered under warranty. Replacement part will cost over $300.... & all that has failed is a capacitor worth a few $'s. Previous models had the capacitor mounted externally - cheap fix! Now I'm expected to pay premium $ to repair. I am getting quotes to replace the hot water system with other reliable brands. Sad to see a once quality company drop their game to this level.

5 ish years old and Leaking rusty water al over the garage from the top disappointing expensive piece of junk and by the looks of it we are not alone with that opinion now I have to spend a lot of time finding out with brand to get to replace it cause I don't think I want a dux again

After having the unit replaced 4 times, again I have no hot water. I bought this Australian
product when they first came out for thousands of dollars and have had nothing but problems and shocking customer service since. All I want is a hot water device that will last more than a few years. Why is it with all this new technology nothing lasts like it used to. Australian manufacturers wonder why their businesses are going broke!!

Recently had a leaking unit replaced under warranty. New unit had a faulty fan. Dux replaced the newly installed unit with another unit. Fan working in current unit however the hot water system is so noisy when heating. It can be heard from all rooms in the house. We were told by Dux this system is noisier than other hot water systems on the market. Not wrong. Find it hard to sleep at night as system is behind our bedroom window. Seems to be heating most of the day.
