Thermann Electric Storage Water System

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 .

I bought and Installed this Hot Water System (HWS) from a local Plumber in Brisbane to replace my 23 years old saxon HWS.
This Hot Water System is good and produce enough hot water for my family (3 Person).
However, there is only single copper element inside the HWS unit and therefore, I would think, won't last as long as Saxon HWS.
The HWS come with Temperature Regulator, which Prevent people from burning their skin when using hot water.
The Water Temperature is nice and warm.
Overall, I am satisfied with this HWS.

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

Lasted 3.5 years before failure! Called Thermann to get told no warranty on any electrical components after 1 year. If you're happy to spend $1000 on a new hot water system every three years this system is the one for you!

Good like trying to get in contact with there warranty department,, my understanding is that Reece are part of this brand, so if your looking at buying a thermann there quick to help and sell you one but a warranty claim forget it, stick with Rheem

Pressure relief valve went. Less than 2 yrs old.

No warranty. Plumber required to fix.

In 40 yrs of life this has never happened to me.

Plumber I contacted said it's highly unusual for such a young hws.

Dont be fooled into buying thermann.
Absolute garbage.

I moved into a brand new flat just 20 months ago. On Sunday my power went out, beyond just the flick of a switch in my switch box.
After a night of no power it was fixed Monday. Five minutes later, POP! No power again. The culprit was determined to be this Thermann hot water service, not even two years old.
Thermann outright refused to take any responsibility for their faulty product, even stooping to condescension when I asked whether this was a reasonable life expectancy. "Oh, you must just be unlucky"
One expensive plumber later and it's working again... for now.
Avoid being "unlucky" like me, avoid Thermann!

Installed a 160l after other one failed to produce much over luke warm. Well over the 6 yrs I've been here so old one was worth it. But this new thermann model installed and after 2 months, it's failed and not getting anything but warmish water. Terrible to say the least.

Installed in mid 2015 - 315 litre electric. Worked ok initially. But conveniently failed when just out of warranty. Customer service when a problem arises is poor. I would find another brand.

Recently installed a 160L Thermann electric hot water cylinder. Considering some of the Dux reviews ( and I believe Thermann is manufactured by Dux for Reece) I was a little hesitant. A 7 year cylinder warranty is pretty good -I assume Dux dont actually manufacture elements or thermostats and 1 year is common for these items.

Cylinder appeared to be well constructed and came with all the usual components and documentation. Cant say its better or worse than other brands at this time.

Only time will tell how well it lasts but if I get 7+ years out of the actual cylinder I will be happy. I will update this review in the future.

We had a 315 Thermann electric storage HWS installed in Dec '14. We were informed by the installing plumber (not his fault, he was misinformed by the supplier) that it had a 7 year warranty. A browse through the handbook (which is given AFTER installation) a day or two later, revealed that the parts and labour warranty is 12 months with a 7 year cylinder warranty.

Fairly woeful considering that it is now malfunctioning at 18 months old and out of warranty. An expensive $1700 lesson!!!

Look very carefully at warranty when buying your HWS.
