This unit was promised to be the best you can get obviously Reece have an agenda to push this crap on to people and also rip them off. This unit behaves just like the rest of the people have posted poor pressure, drops out for no reason during shower, goes absolutely stone cold as soon as someone flushed a toilet, takes far too long for hot water to arrive the list goes on. These others are not lying about their reviews. I would happily go back to a rheem stelair tomorrow I was completely satisfied had it not given up after 15 years. This hunk of junk is only 9 months old and is pathetic. I stayed patient and tryed to troubleshoot it until now, but now if fed up do yourselves a favor leave them in store.
I have had a C6 26L for 2 weeks, I cannot get it to fault as described in other posts on here. mine heats the water instantly, hot water in less than 10 seconds (3 meters from bathroom) I can turn on any other tap in the house and it does not effect hot water or pressure.
Wish I bought a Rinnai
We've had our Thermann 26 for years now and it's been the same peice of junk since day one. I had a plumber recommend it so went with it as it was cheaper than Rinnai, had I have know just how crap this would be I would've spent the extra 700 bucks. Every single shower will cut out completely for a good 30 seconds, I've checked out side and the unit totally cuts out you can hear it reigniting.... THIS HAPPENS WITHOUT ANYTHING ELSE BEING TURNED ON!
It also has a fairly strong gas smell coming out of the unit during operation.
It's become a way ...

Absolute crap !!!!
worst hot water system ever !!!!
purchased 3 months ago & have nothing but regret... if someone flushas the toilet while in the shower it goes instantly cold, some one turns on a tap instantly cold...don't even think about using 2 showers at the same time..I want to remove it & belt someone over the head with it !!!!
Not a bad unit but water is not hot enough
When I purchased our Therman 26 with our house package I asked for the 60 degree model advised that I won't need it. Told Thermann 26 produces hot enough water crap!! Water is not hot enough to wash dishes or have a decent shower. Told by Reece that you cannot replace the thermostat with the 60 degree controller. Apart from the temperature issue pretty reliable.
Worst thing I have ever purchased
Never had a problem with my old electric storage hot water but made the mistake of changing to gas with a Thermann gas system. Plumber installed this system and from the start it has had such inconsistent temperatures - suddenly runs completely cold for 5-10 seconds which is not fun in winter. Complained to the plumber that installed it who talked me into getting new tapwear as it seemed the cold tap was old and worn and that was the problem. After testing the new taps he noticed when the hot tap was on solely it worked fine for a few seconds t...hen dramatically dropped in pressure and confirmed this by running the water straight from the hot water system outlet. Called his rep at Thermann who said it was the gas regulator so he replaced that. That has done nothing and is worse than ever. I dread showering every night as it fluctuates between extremely hot and freezing cold constantly.

Unit works well! Disappointed in the plumber who recommended a 50 degree unit to replace a 60 degree unit
Recently had new Thermann26 installed to replace an old unit. We were not getting hot water to several locations in the house. I have had little response from the plumber but great response from Herrmann who have made attempts to come on-site to review. The issue is that the Thermann 26 is a 50 degree unit replacing a 60 degree so water temp lower than previous. It appears probable negligence on part of the plumber. Fantastic support from Thermann people to resolve the issue. Highly recommended.

Reliable Quality Built steady and efficient Hot Water Unit
This is the best built hot water system money can buy. A little pricey compared to the competition but its quality built and engineered in Japan.
Have as long a hot shower as you want. Strong Reliable little unit with no issues yet, 3 years in. Will never go back.
I’ve been a builder for the last 5 years and 12 years as a head carpenter building domestic homes. I had this hot water system installed on my new home and It takes over a minute to barely warm water coming out of my taps. Had Reece come out twice to see what’s wrong and they thi j it works fine. If I’m having a shower and someone turns on a tap anywhere in the house the water immediately goes cold. It is so bad I truly cannot believe this piece of junk is on the market!
Purchased in March 2020.
Very low pressure
Purchased this unit on recommendation from plumber after my old storage unit died. Pressure from this unit is atrocious. Shower at 1 end of the house goes completely cold mid shower and you have to turn off the cold water then wait for hot to come back. If you want to use two appliances like the kitchen sink and a shower.... forget about it.
Positive is it never runs out of hot water.
Definitely should have gone for another storage unit.

Best gcf i ever used
Previous dux heater used 45 kg bottle in 6 weeks only 2 0f us and hot water only thermann is at 11 weeks and still going spot on hot water and easy to use
Would absolutely recommend it we are on tank water with pump
No problems whatsoever
This unit is very efficient at delivering hot water within 15 Seconds.There is little water temperature fluctuation unless another person opens another tap.Overall i would say this unit is the best so far and would not go back to hydropower.
Purchased in December 2018 at Plumber for $800.00.
Bought this heater on May 2018 by the plumber for a new house, moved in January 2020 when I noticed that the heater has a problem.
If you need to have a shower ask all the house occupants not to use the water in the house, otherways you will have a cold water shower.
called Reece for assistance, and the advice was to stop using the water in the house while anyone having a shower.
Now I have to buy a new hot water system because Reece says they can't help.
Purchased in May 2018 for $1,141.05.
Installed this unit on recommendation of plumber who is a good man but obviously there is some sort of heavy promotion or leverage to get this happening. Have not had one shower in five months that hasnt gone cold at some point. Using flick mixer have to turn water to full hot wait two minutes then mix cold in and hope I can wash the shampoo out of my eyes without going cold again. My wife is ready to pull the fing thing off the wall and throw it on the plumbers front lawn. At 55 years old can honestly say worst purchase of my life!
Very happy with this unit
One month in since I installed the Thermann 6* 16L and I'm very pleased. I only need to wait around 15-20sec to have a very hot water in the shower (@60C), I don't experience any water temp' fluctuation, and the water flow is steady.
the only reason I gave it 4*and not 5* is because you can't change the temperature without buying the R/C for an extra $100.(which I didn't buy)
Please note, the system is for serving two people with minimal use( showers and a bit in the kitchen ), the distance from the unit to the shower is around 8 meter, and to the kitchen is around 4 meter.
The installation was straightforward and cost $1100 including the unit.
Constant waste of water. From every outlet I have to wait ages for any hint of hot water with the cold turned off. The temperature also fluctuates still with the cold off. Sometimes it doesn’t even kick in and send hot water, I’ve had to go and turn the unit off and on again. Another waste of my money thanks to a plumber highly recommending it. Very very disappointed

Agree wholeheartedly with Worst Item Ever
So much water is wasted to actually get hot water. Bought this thinking it would be more economical, stupid decision. Used to be able to have a 5 minute shower, now to get 5 minutes of water at a perfect temperature I am standing there for at least 25 minutes. Shower goes cold after about 3 minutes. No good just trying to adjust the hot water tap. Have to completely turn the shower off and start again - so again you're wasting litres of water to get hot water. Our gas bill is also now a lot more!

Thermann 6* 20L C/Flow 50DEG NG
Very pleased with the Thermann 6* 20L C/Flow 50DEG NG unit. The installation is for a small cottage with 1 bathroom. All kitchen, laundry and bathroom outlets within 14 feet of the heater. The install took about 5 hours and included the removal of the DUX electrical off-peak tank and changes to plumbing pipes in that area. I am new to the 50C hot water regulation, but the water seems hot enough to wash dishes in and the shower is comfortable to bath in and flow seems fine. I did have the water saver shower rose removed and a standard rose fitt...ed to the shower, it is an 8 litre per minute WELS shower head. The all up cost was $2192.20 which included $220 for a level 2 electrician to remove the off peak meter from the meter box and $126.50 for the electrician to install the outside power point and terminate, in a block, the off peak power line.
Only want a good shower
I thought that it wasn't very good for the first two years, terribly bad pressure in the shower, good every where else, I had taken out shower head restrictor didn't seem to make any difference,, finally found another restrictor at the inlet, goodness two of them, my shower is now perfect

Had an elderly relative stay who needs a shower chair, she had to bathe at the neighbours - she would either have 3rd degree burns or be frozen at our house. Continuous hot water - what's that?????

When the gas is disconnected, how do you relight the pilot light; is there a pilot light; this is for the thermann 16 model continuous flow
Thermann Hot WaterThermann
Thank you for your inquiry. The Thermann 16 is power-assisted and does not have a pilot light. All you will need to do is as follows.
Ensure your Thermann unit is connected to a powerpoint and turn on, then ensure that the cold water is on feeding the unit. Then turn on a hot water tap, and you should have hot water at the outlet.
If you have any further issues, please email [email protected]
All the best,

Hello I have a Therman 26 unit installed about 5 years ago. It has worked perfectly until 12 months ago. During a shower it will go cold for a couple of minutes. I have good pressure, plenty of flow going through the shower head and new taps. It seems to be worse in summer when running the shower at a lower temperature. Running town water and gas. Any suggestions?
