Bulging rust and leaking at 7yrs – I have 4 of these in similar properties. They are just over 7 years old so now out of warranty. One started leaking water at the top. When I checked it is all rusty around the anode and HWU has to be replaced. Checked a second HWU and it is all rusty so I won't be able to change the anode. So I'll have to replace more HWU. Won't be buying this… Read more
brand again. Not happy at all. (Update): Got nothing from the supplier as they weren't interested and the manufacturer didn't care.
Poor Product – Installed Dec 2022, 18 months later thermostat went. Manufacturer's spare parts and labour warranty only valid for 12 months. Do not recommend Show details

Would not recommend – We had this unit installed in June 2022, at a cost of $1900. It was to replace our previous hot water system (a different brand) which, incredibly has lasted 22 years. Unfortunately, after only 13 months, the PTR valve on the new system failed, causing us to gradually lose hot water over a period of 2 weeks in the middle of winter, culminating in… Read more
no hot water eventually. We contacted a plumber who found the valve to be leaking and commented that he had never seen a valve fail on a system this new. At a cost of $300, he installed a new one for us. Upon contacting Thermann, we tried to make arrangements for the valve to be reimbursed and despite an initial phone call and email from the 'Product Specialist' we have received no further correspondence regarding how to get this new part reimbursed. We do not even know if it will be covered by the warranty, which, not surprisingly, expired 1 month prior to the valve failing. We have had no communication since. Between the poor communication and early failure of the valve on an expensive system, right out of warranty, I do not feel I can give this product more than 1 star and certainly will not be purchasing from this company again.

Works well for my house hold – I had this unit installed January 2022 I didn't look around for certain brand just what my plumber supplied and to date the system has worked very well and has never run out of hot water. There are usually only the 2 of us but with the grandkids etc you could have up to 8 people using it and still keeps up, now to be fair my system is on constant… Read more · 1
power which apart from a bit extra on the power bill is fine. I should also note that in February 2023 the thermostat seal failed causing a small leak and tripping the RCD, I didn't bother calling the warranty mob as for small amount (around $100) the plumber replaced it which was much easier for me at the time. Not sure why the seal failed but in the end its a rubber real and seals fail, it could also be that because the unit is always heating this may have "helped" I will find out next year on that one. But again all in all happy with the system.
I have never had a hot water system fail so quickly – It was made in 2019, and has just failed. I’m really disappointed . It services a house of 2. I am personally used to hit water systems lasting a good 10 years plus so 4 years was a huge letdown. Thankfully the local plumbers were great and replaced the thermostat within 24 hours.but I am disappointed that this system has cost us another $200 and inconvenience so early in it’s life.

Leaks under base – I purchased this Thermann 250 solar tank but not connected to solar. It had bad leaking problems leaving a large puddle around it. The infrared seeking helicopter looking for fire ant infestations identified a hot area on the grass near my house and wanted to inspect. It was the tank leaking. I can see water dripping under base as I have it… Read more · 1
sitting on a plastic base plate. Reece plumbing replaced it in 2018 but not before a tiresome effort to get the warranty accepted. Two years later this started leaking also leaving a puddle. My electricity bill has overtaken my 6.4kw solar systems ability to save me money. If I chase up a warranty again I may have the same problem. I have spoken to a Thermann rep today and he assures me that it’s a rear problem and I’m still covered under warranty and he will sort out the issue. He asked me to give a good star rating and modify my statement. This I did as he was actively involved in sorting out the issue.
System failure before 5 years – I bought a thermann hot water system on 11/03/2016 which means it is less than 5 years old and it failed this morning. It is a disappointment for a well branded name like yours to fail within that period time. My old system lasted 14 years. I was not expecting that long but at least to last for the first 5 years which it has not. Very disappointed. I had to pay $200 for something it should covered under your warranty (7 years) Show details

Was working fine now not producing enough hot water for 4 people – Installed by a licenced plumber and it replaced a 17 yr old Saxon. Less than 5 years on and with regular servicing it's now not producing enough hot water for 2 adults and 2 kids. Have tried to contact them to no avail. I will never buy another one and will be telling everyone to steer clear Show details

Rubbish Product & Warranty – Warranty replacement of leaking tank 6-8 mths after $1600 purchase. Plumbers charged $304.50 for “difficult warranty install”. Install ONLY occurred because of their faulty product and I was forced to pay the installation which took 1 plumber 4 hrs and he was assisted by my son. Install comprised cutting and installing one 30 cm length of pipe with 2 pieces, lifting tank over toilet with assistance of my son . Show details
I retract adverse comments regarding the above. I was contacted without having to chase Thermann… Read more
Great Product and been in house for 2 years now hasn't missed a beat – Installed and recommended by my mate who is a plumber. Supports a family of 4. Will be putting a 315 in my new house that I am moving into in 4 weeks just because we are getting dishwasher Show details
