Stops working in windy and wet conditions
The unit stops working when you need it most, in cold, windy and wet weather. I used the reset button inside the unit to restart it but now it seems to be dead. I am not going to call Bosch as it's seems like a waste of money. Better install a different unit from a more reliable brand.

Water leak
I bought my Bosch 26E NG in May 2012 and it has worked well until now when it recently sprung a leak in the copper pipe on the top LHS. A plumber tried lagging the pipe but it is still leaking. He thinks it could be fixed through welding but is concerned at the proximity of the water leak to the electrics. Is this fixable?
Purchased in May 2021 for A$963.63.

Great system
Hi. Excellent system. Mist people complain about the performance of this system. I had problems with water not hot enough or cutting out frequently. I called my plumber and he found that the pipe going into the system was too small (15mm). So when i turned on my gas cooktop or ducted gas heating, it would cut out the hot water system. Requires minimum of 20mm to operate correctly. All i can say to those people complaining is, get your plumber to check the pipework going into the hot water system and any other gas appliance you have. You may have same problem as I did.

flow hot water unit, it does require a larger flow of gas compared to that of a standard gas storage unit. As you mentioned, this unit needs 20mm pipes to operate correctly and it’s great to hear you had a good plumber to take care of your pipe upgrades.Similar opinion? Write a review on ieatwords.com.au!

Never Missed a Beat
The old storage gas hot water system in the roof cavity failed after 30 years (Beasley) but it was installed during major additions and to replace it would mean removing part of the roof or ceiling. So we had a Bosch 21e installed outside. It has been 3 years and it has been reliable with no problems at all. I installed a BOSCH MAIN CONTROLLER YPRM67XBN (about $100) not long after the heater was installed and it was the best thing I ever did. We rarely need to use cold water because the controller can be set to any temperature between 37 and 50...Read more
ºC. My wife and I prefer different temperatures so we just adjust the controller before taking a shower. In winter I use a setting of 40ºC and in summer I use the lowest setting of 37ºC. My only criticism is the temperature settings at the lowest level is inaccurate. 37ºC is below body temperature so it should feel cool. But on hot days it's sometimes too warm for me and I add cold water. Have recently bought a Bathroom Controller YPRS67XBN which will replace the main controller in the bathroom. The Main Controller will be moved to the kitchen. I note many complaints about the Bosch 21e and can only say use a good plumber. Our plumber made sure there was sufficient gas pressure and no leaks between the meter and the house. The Bosch 21e gives us a much better shower than the previous roof storage heater, and the gas bill has not changed noticeably.Similar opinion? Write a review on ieatwords.com.au!
be very wary
model 16E - wished I had never brought it. Wastage of cold water is a major problem for me, at least 5 to 9 litres of cold water just for 2 showers in the morning, then the kitchen cold water add that on pure wastage. spoke to a plumber who installs another well known brand rang gas works and a technician came and re-tuned it, shut this did that and is now working like it should have been.

Excellent hws.
This hws has been totally reliable and great at supplying us piping hot water over the past several years. It has never even been serviced oops.
I am wanting to be able to adjust the water temp now though as our new dishwasher needs a lower temp for ingoing water (there is only a connection to a hot water pipe).
I am unable to open the 4 screws on the unit.. done up so tight, none will budge. As I need to call a plumber out to adjust temp anyway, I was wondering if a controller can be added to the unit and will it give me the full range of temps ie 50 to 75 degrees? How much do the controllers cost approx.?

Fairly instant & very expensive,
I changed from solar to instant gas in an effort to save water. What a let down. I need to run my 'instant' hot water twice as long as my old solar took to heat up. The cost was exhorbitant. Over $3000. now I have to pay for the power and waste twice as much water.
I have to change my review and apologise to Bosh. The installer informed me it was working correctly. After a year of miserable showers I found a real plumber who said the water was travelling back & forth unnecessarily in too small pipes. He has fixed that problem. However when set at 50 degrees it reaches about 43 and stilll takes a while to get to the kitchen. Still wish I'd stuck with Solar.

Terrible! Get a Rinnai instead!
Ever since installation a couple of months ago, this unit has not been dependable. Water + gas available but unit does not fire up as it should. I was told it's a software issue... I run a guesthouse and I can't have an unit I can't depend on.
I have insisted to my plumber that I want this unit OUT and a Rinnai IN. My previous unit lasted for 15 years before needing to be replaced!

Turns off in winter when the temperature outside is low
It worked good the first couple of years and just before the expiry of the warranty it started turning off and the water wouldn't flow at all. We called Bosch and they said to call the plumber and do a maintenance. We did a maintenance in autumn but when winter came it stopped working again, this time the water running but no hot water at all. It can start again after turning on and off for 10 times but Leaving the children by themselves in the shower to run outside in the rain to switch it off and on again is a big risk. Not happy at all with ...Read more
this system. It was annoying that Bosch didn't care and told us to call our plumber, I think there is a problem with this hot water system and they need to offer replacement with different model. It was still under warranty and I think when we bought it there was mentioned that there is a 10 year warranty on some parts, what a joke.Similar opinion? Write a review on ieatwords.com.au!

We have had a Bosch HWS in WA and it worked well. You have commented that the 21e unit would not work on cold/wet/windy mornings. Would you mind saying HOW you fixed your Bosch 21e. We have a new 26e and it takes ages for the hot water to be delivered a short distance of 2 metres. Many thanks.

OMG - This is living!!!
You don't know you have lived until you purchase a hot water system with remote temperature controller units.
Firstly the house we bought back in 2015 had a 10L/pm unit in, can't remember the brand but they are common as muck and the hot water trickles out.
Going from 10L/pm to 21 was like a dam busting open full of hot water.
We bought our unit 2nd hand from a demolition recovery yard for $200 and it has worked flawlessly in the 18months we have owned it.
I went out and bought 2 remote temp control pads and fitted to the bathroom a...Read more
nd kitchen @ around $70ea off ebay. There is nothing better being able to step into the bathroom and turn up or down the temp based on how you are feeling and then just turn the hot water tap on and the water is streaming out everytime at the temp you selected.Similar opinion?

not a right answer
as I said my 21e problem was, when I opened cold water the system turned on, finally I found the right answer, because I did bathroom renovation there was some air on the pipe and the air pressure on the new pipes caused the system turned on even when I opened the cold water tap.
solution: easy, open the new taps connected to the new pipes and let the air leave pipes, and then every thing back to normal.
Thanks

Design flaws that product support don't know how to fix
I can reinforce comments by at least one other poster on here where their unit failed to fire on cold/wet/windy morning - basically when you need it most. This started happening to me almost without fail just out of warranty.
I first used one of the recommended service providers on the Bosch website who adjusted some levels on the unit, and by that time it was probably dry enough to work anyways. Next cold morning it fails again, so I call him back, but he doesn't know what else to do. So I call Bosch who then say its better to call one of t...Read more
heir warranty repairers rather than a service provider detailed on their own website. They end up doing a minor fix. Which again doesn't work the next cold day. Call them up again and they change the gas valve thinking that is the problem. By now i've spent basically as much on repairs as the unit originally cost. Although it came into Spring/Summer then, so I figured it was fixed. Come Winter next year it wasn't. I had my suspicions Bosch had literally no clue how to fix it, and ended up going to Bunnings spending $5 and fixing it myself. ($2.50 of that was for a sausage sizzle). Kind of wish i'd done that in the first place as it would have saved me a ton of cash. And for two winters my fix has been rock solid. Touch wood.Similar opinion? Write a review on ieatwords.com.au!

Not overly impressed
Have always had temperature fluctuations. Just renovated the bathrooms and found a lot better. Unfortunately the plumber then made us install a pressure reducer at the main tap. Flow restrictors have been removed from the tapware and still shocking. Now worse than ever. Fortunately we don't live in a cold climate.

Very good,no problems to date,own two.
17e has been great! One unit supplying hot water to a food van,another, domestic supply.
Both units will take some effort to restart should they continue to be used on an empty cylinder.
The restart usually takes 5 minutes with some switching on and off of the power supply.
Best to try and avoid the run-out situation. Simple cylinder changing does not effect units.
Both units 2 plus years old.

Complete Rubbish. Do not buy one
Hi, We have had nothing but trouble from this E21 hot water service in the whole time we have had it & has cost us a fortune in plumbers in the 10 years also. Our son who has just left home to move into his own home & has bought a RHEEM and has not had to buy a controller as we did which made no difference to our BOSCH & he is happy as Larry. Do not buy one. kerr5y

Bosch Hot Water 26 Continuous Flow unit.
The Bosch 26Lt Continuous Flow unit is a very reliable Hot Water unit which my parents bought one and they are very happy with the unit. I had one in my previous place and I'm going to get one next month. I would recommend the Bosch Hot Water unit 100% they are a very good hot water units.

Unreliable
I purchased Bosch for its name for reliability and not by price and when I first installed this product it ran without any issues for about 14 months, then it would shut down and not supply water hot or cold. I found pressing the resett button inside it would function again for anywhere between 1 to 3 months. Then it started to fail on a more frequent basis untill finally it would not reset at all. With nothing to lose I disconnected it from the mains, unplugged all the connectors one by one and sprayed with contact cleaner (not normal CRC but...Read more
CRC Lectraclean 2018) and worked them in and out to clean them before plugging them back together. I reconnected the power pressed reset and the unit functioned again without fault for about 6 months, when it failed again, at this point I repeated the proceedure and we are at month 3 without a failure. The problem seems to be worse in the winter months so it looks like poor design in the plug and socket department. It is apparently designed to operate outside and my unit is in a protected corner of the house.1 comment
Update
Bosch water died again today so it made it 3 1/2 months worked after reset. but it's a drag, hey Bosch how about a service bulletin or a schematic then I could fix it properly

Absolutely terrible product
Only moved into our house in March and we have had nothing but endless problems with hot water cutting in and out and also when swapping the gas bottles. Followed the manufacturers instructions by turning the water and gas off and on numerous times, with no luck. How Bosch ever got these products past quality control is beyond me! I'm off to purchase a Rinaii!
