Lasted me over 12 years
This unit has lasted me over 12 years maintenance free! I installed a cupboard around the hot water unit so it isn't very noisy. Im only replacing because the thermostat has failed. Excellent product for the price.
Purchased in April 2009.
They don't last very long
It's one of the cheapest ones around. But I put in a new unit in 2011 and again in 2018, and now have to get a brand new one since the second one no longer works. Will be going for a better unit this time round as the amount of money spent calling out a plumber just isn't worth it.

Not bad luck—bad product!
When in little over a year I had to have a second Wilson SuperX replaced and asked the plumber about it, I was told, ‘Sounds like you’ve just had a bit of bad luck, mate’. A lazy answer in my book, for now the third one’s gone kaput. that’s three in under five years total. No good. And not a matter of luck. After a year, sometimes a tad longer, the water pressure drops and the water doesn’t rise above warm. Next stop: glacial waters and soap. Would not recommend to my mother in-law. Well, maybe.
If I could give zero stars I would for the Wilson X HWS
I've purchased 4 of this crap HWS over the past 10 years - they seem to work for about 6 months then there's endless problems with the water temperature etc. The guy from Mt Hawthorn that services them Glen - is also a scammer. He charges exorbitant fees to come out to look at the HWS and blames it on the shower head which isn't the case as I've changed the shower head and taken out the restrictor and the problem still exists - the water is too hot and then you turn on the cold water and something cuts out the HWS so its either boiling hot or ...freezing cold - I've had enough of the Wilson X - I'm going to replace it with an alternative and never buying one of these stupid HWS again. Just a waste of money and effort and call-out service fees. The people over in the Eastern States are full of it as well and blame the installer when clearly its the product in the first place. Don't waste your money and buy this - it'll only give you stress.

They only last 12 months, ive been through 4 in 4 years!
I have a rental and have had to change mine every year! Today it went, only 9 months old since i replaced it, a year before that one and another year before that. Terrible quality

Do not recommend - 12 month lifespan
Wilson SuperX (model WISX) Unit was installed in a rental in Sep 2019 (manufacture date July 2019), provides good hot (HOT!) water until one or more of the elements burns out, as happened sometime Oct 2020. Tested by measuring resistance across the 3 elements, one of them is open circuit. The unit includes thermal protection circuitry to cut off at some point but this apparently doesn't stop possible burn outs.
In general, there's no built-in temperature control or sensing, meaning temperature varies significantly based on water flow rate. Once everything is warm however, the temperature generally stays the same. Also makes a loud clicking noise when activating which can be very annoying in a home environment.
Purchased in September 2019.
Life span in WA is circa 3 to 4 years. The elements in most cases fault to earth. Change the quality of the elements
Main problem is the poor quality of elements
The main fault is that the copper sheath splits.
Element leaks to earth.
Change element to nickel sheath and this may give the element a better life span.

Zero Recommendation Hot water system
I got this with one of our rental and it's just dead in 4 years, can't believe that we have to spend another $1200 for the new machine, It's really not worth for money and not recommending Wilson Hot water system.
Not recommended to buy this company product as many license plumber also discussed this product warranty or service.
Purchased in July 2016 at Dynamic plumbing for $1,100.00.
Repair under warranty quickly
I have one of these systems in my new house, dont know when installed but manufactured in Sept 19. phoned on Monday, was repaired within 48 hours. I somehow don't think it will last long reading here
Super Hot or Super Cold-
Its either very Hot or Cold, no middle option
I called the customer service, they temporary fix the issue with some set up but issue came back again in few months. this time when I called them, they simply said item is out of warranty without any support
very bad product not worth the money you pay
Purchased in June 2016 for $900.00.
2 months out of Warranty
I've had no problems with the water heater in my own apartment, apart from being extremely hot and sometimes hard to get the hot to work (which is probably to do with my mixer tap), however the rental I have literally exploded 2 months out of warranty. Wilson replaced the unit but i was charged the installation fee. I paid this then emailed Wilson that I felt this should have been included. I was expecting a fight however they responded immediately and have covered the labour too. Thank you, good customer service, hope this one last longer.
Rip off prices have bought 6 units
Have had 6units in 18years,the best of them lasted only 6 years,the worst one lasted less than 2weeks!! I have just replaced another one which has lasted 4years! Noticed the price has increased by $102 since I purchased the last one in 2014! Quality control,forget it! 5years warranty that's a joke, you get 2years on a fully installed replacement unit,paying nearly a $1000.Do yourself a favour, don't buy this crap!!
Absolute crap!! You must be out of business
Shameful business.. Should close down. Only comes with 2 years warranty.. Goes Capt right after. You can't change the damn element but have to buy the new tank which is the whole unit.. Rip off absolutely.. Such expensive device must be sold with minimum 5 years warranty.. That means you will be out of business.. I hope
Either freezing or scolding hot
Absolute rubbish, two plumbers have told me to get rid of it and get a different one. Known problem. Water comes out either scolding or freezing and no where in between. Only way to have a decent shower is to have a tap in the basin running hot at the same freaking time!!! Washing machine will only run hot water even on a cold setting. Clothes come out scolding hot??? Even after adjusting the valve on the water system.
Scolding or freezing
Has a hot water low flow rate shut off. There is no thermostat to adjust hot temp which would solve this problem. Such a frustrating unit! Would not recommend.
Our options are now to try a increase the bore size pipe to the boiler to try and get more water pressure. Or solder in some rheostat thermostat control. Most likely I will just bin it and get a real boiler !!
