Stay well away
After installation the Optiflow 26 would not work without going outside and turning off and on to reset it every time. Once operating the unit surged providing uneven water flow. The unit also takes too long to heat up and also heats high above the set temperature. Had a Bosch technician come out and upgrade the software, which allowed me to take showers without going outside to reset. The technician had to come back a second time as he hadn't calibrated something or other.
Now the unit constantly stops and starts 24/7, even when no hot water ...is being used. Everytime I call Bosch I get different information. Now about 7 weeks after my first call to them and the manager at Bosch just tells me its normal. I purchased 3 of these units, 2 are installed on another house and the faulty one is at the house I live in. I have never heard the other 2 start at all unless they're in use. Finally last week a nice lady at Bosch was talking with a technician whilst taking my call. The technician advised that the unit should be returned as the problem cant be fixed. I have sent emails to Bosch, made several phone calls. Now the manger at Bosch wants me to send a video of the unit stopping and starting. Ive just spent 2 hrs in the wind and rain trying to get a video of this and couldn't. Obviously sending large files via email doesn't work and everytime I stopped the video to start recording again I would miss the noise. Totally over it and now going to the ACCC. Bosch management have a lot to answer for regarding service on this product. They stopped making these units for obvious reasons, and now refuse to help customers who have fallen victim to their faulty and poorly designed units. Not good enough.
Purchased in February 2019.
The unit constantly requires to be turned off & on again to work.
Sometimes, the hot water doesnt come on at all.
There have been countless time this has happened over the last 1 year of buying this product. Never trusting Bosch products again.

Avoid if you can
Stopped working on 366th day. Warranty ran out. Had to call these clowns twice while under the warranty as it would not heat the water. Chucking this piece of crap in the bin. Terrible terrible stay away from this product
Hate this so much!!!
This is the worst hot water system I've ever had, unit is right next to bathroom yet I have to run the water for nearly a minute to get it hot when having a shower. Gas bill is ridiculously high as it seems to run all day, I now turn it off when I do not want hot water to try and reduce my gas bill.
Have given one star but would give -5 if I could. Absolute rubbish and Bosch you should recall this product and offer everyone unlucky enough to have this a Rinnai or Rheem anything but your brand
Purchased at Renting property.
Avoid like the plague!!!
We are extremely unhappy the water comes out Luke warm at all outlets. We can not have a bath with out keeping the hot water tap running the whole time and releasing water. We are washing all the dishes twice and having to boil the kettle to fill the sink to be able to get them clean. When the water gets to its hottest temperature it will then have a section of cold run through then heat back up. The amount off water we are wasting, our time being consumed with re washing and getting in and out of the shower, keeping the bath tap running and the extra cost on our bills is causing a great deal of stress. We have emailed the company to resolve the issue and no response. ACCC is my next step.
Changed from Electric storage to Optiflow 16L with high expectations of saving $$$.
Two units installed through warranty period. Errors from install and regular wafts of gas. Will be replacing asap.
Purchased in September 2017 at ELGAS for $800.00.
Absolute rubbish, inconvenience, not recommended
Only rated one star because it wouldn't choose zero, second unit after first one being replaced under warranty due to issues now the replacement has crashed. No wonder it has a 6 star energy rating, super efficient if you can't use the damn thing.
C1 error!!!!! So sick of seeing this
Purchased the Optiflow 26l, on January 2018, I have had a C1 error twice in 12 months ,and of course each time on a weekend when finding a plumber for less than $200.00 for call out and 15 minutes is impossible. I have taken 2 cold showers and boiled water on the stove for my son to bathe in. Was told the circuit board needs replacing and was even told to just replace the unit cause he’ll be back out in 3 months time to fix other things. Still waiting to hear back from Bosch. Very disappointed, not what you expect from Bosch products. If you are considering a Bosch water heater avoid it if you like hot water in the bathrooms.

Rubbish, broke after 12 months
Unit conked out after 2 mths use, I was told by the company who installed it that they've had constant issues with this and won't install them anymore because they're rubbish and have constant problems.
Purchased in June 2018 for $730.00.
One year of tepid water
No high demand in house, 2 people. Can not obtain hot water for 12 months. Water is always tepid, taps and showers run for mins in order to get warm water. First time that I have filled the bath today, nearly full, cold and system is on wall of bathroom. Have had Plumber out months ago to tell me that it is set at regulation temperature and have had a meter upgrade also..Water bills have been MASSIVE as waste water trying to obtain more than warm water in shower and sinks..Worst purchase ever made!
Purchased in July 2018 for $1,500.00.
Needs restarting to make hot water
We brought this product after much research and after talking to the Bosch technical staff for our campground. Had it in for several months and it just starts randomly stopping. No Hot water. All it needs is a restart to make it go again. This has caused extremely bad damage to our Brand name as we advertise having unlimited hot water for the showers. Exactly why we chose this model. Campers contacting me at 11pm to tell they want hot water!!!
Now I find it is a known problem? Whats going on Bosch?

Hopeless heating times
Like other reviewers, we have found the time to heat impossible. Our bathroom tap is right next to the heater - maybe 2-3m of pipe, but it takes 30 seconds to get hot water. Same problem with going cold and reheating if you turn the tap off even for seconds. The local supplier did get a serviceman out in a couple of days - they replaced the PCB but it has made no difference. I suspect it's the "efficiency" - will be pushing my builder for a different unit to replace it.

Works but noisy when not in use
Ok does it provide hot water yes. Although it will sometimes go cold at random times. The most annoying thing is the noise it makes. Every few minutes it makes a whirring grinding sound. I had the installer come out and take a look, he said it's the water pressure servo, and it's normal. Ok not happy with that answer, I called Bosch warranty line, they also told me its normal.
So really, its normal for the Optiflow to activate the water pressure servo every few minutes for the life of the machine. Even when the machine isn't in use, and hasn...'t been used for hours. It just keeps activating it. Don't install it near a bed room, or all you hear all night is this servo going off every few minutes. Video of the sound here. https://www.youtube.com/watch?v=kxM039d-T1E
OptiFlow 26 does not work. Bad Product and Bad Customer Service !
Purchased Bosch OptiFlow 26 hotwater systems last year for my new home. The very first day it was installed by my licensed plumber it did not turn ON and started leaking. The plumber suggested a replacement. I have sent many emails , phone calls to Bosch warranty but no response. Despite the unit in warranty there is no replacement and there is no response from Bosch. Unbelievable !!!
As per the supplier the unit has problems and a recall was initiated for this product. The supplier cannot offer a replacement as it was a Bosch quality issue ...and they do not have any units in stock. Bosch is not very open about this problem and are not at all helpful. I have seen many bad reviews about this product but the worst experience is their customer service. Will be writing to Department of Fair Trading and ACCC to complain about Bosch.
My faith in Bosch brand seriously dented
My wife and I bought a house in Montville 4 moths ago with 2 guest cottages attached each supplied by a Bosch Optiflow (2X16 and 1x 26) system. Yesterday we discovered that the one was not working. I phoned Bosch service centre number 1300307037 and gave them the serial number of the unit while stressing the fact that guests would be arriving the night thereafter and that it was essential that the unit be fixed. I was assured that someone would be sent. I am still waiting.
Out of despair I contacted the local gas fitter who tried rebooting th...
Avoid - bad product, terrible customer service
Ordered a brand new unit, it was faulty. Bosch said they would replace it immediately. A week later and it still hasn't been replaced. I've had no water for a whole week. I've call Bosch and their service center multiple times. Despite guaranteeing it would be here within 3 days, I am still waiting.
I built few Units and have 3 Bosch professional hot water 26L and it has nothing but problems.
Rubbish unit and stops hot water all of a sudden. No warnings and had to rest the power and then cal several plumber. Seriously this reviews above shows that this unit had to be recalled and it should be illegal to sell such units. I hope Bosch can respond quickly as I have completed their online complain form.
This product is causing lots of grief especially for family with young kids.
Imaging having to to reboot (wait for 10 sec on and off) the system at least once a day. Worst when my young kids are showing during winter and the hot water fails. Even worst - having to go outside the house and reboot the system during heavy rain. I am utterly disappointed with this product despite Bosch being a reputable brand. Please do something Bosch come on. Looking at the all the reviews here, seems like the issues are pretty consistent. I live in Brisbane and Bosch direct contractor is Gasworks. Gasworks is the company that does all m...y repairs and replacement. Here's the timeline of just how many repairs and replacement made within a year. Note that I moved in to my new house in July 2016 and all appliances are brand new: Oct 16 2017 - Unit Replacement Nov 13 2017 - Unit Repair Nov 29 2017 - Unit Repair Dec 4 2017 - Unit replacement Today Nov 30 2018 - Unit starts to show signs of trouble 3 days ago having the need to reboot the unit at least once a day.
Unit fails to delivery hot water with out powering on and off.
Just moved into new house and this unit plays up every day, randomly, we have to turn it on and off to get hot water. Made a call over 7 days ago and no one has been yet. I have 2 kids and a pregnant wife at 36 weeks. Paid the extra for Bosch and am very disappointed.
I moved into my home in April 2018. there was a new Bosch infinity heater on the house. this began playing up almost immediately and had to be powered off at wall then switched on for water. this was occurring every two weeks. then this would not work. So contacted the supplier, 1x week later the repairer came out and reset to factory. This worked for a matter of 1x month then stopped heating at all. meantime the water flow was like an old man with an enlarged prostrate. very poor flow. Then the unit packed up altogether. I was withou...t hot water for 2x weeks while waiting for Australia to make a decision. A new unit was eventually installed and within a week the water went tepid. I notified the contact people at Bosch and was told that the technician would be there that day. No show. Fortunately water heated again, but flow still poor. Then on 26 August the unit packed up again. I am now still waiting for this to be resolved once and for all. Bosch are no help and are now blaming my gas bottles. My son who is on the same property has the same bottles as I do which is 18kg. different unit, never had a problem. This is a dog, does not even rate it a star. the Service is also a dog. I would not own one given a choice. meantime I have to travel around Auckland for showers. Bosch does not care that this is happening.

Questions & Answers
Has anyone found a resolution with he issues with this system, It has been replaced, I have tried 2 independant plumbers and Bosch recently came for the 2nd, no third time and changed the Motherboard, the model had Mother board problems apparently ? (made no difference) a year of hell with this thing just no hot water to wash diahes at all, no hot water on bathrooms or bath and $500 and more water bills (double) trying to run taps forever to get luke warm water. What is the solution?
The motherboard was changed in mine the second time with the second unit. The third unit was upgraded by Bosch to the Bluetooth model with assurances all faults have been resolved. I guess only time will tell.

Hi Sharon, thank you for your question, we're sorry to hear about the difficulties that you have been facing. We believe that you have gotten in touch with our Technical Team already and have organised the replacement of your unit. We trust that this will rectify all of the issues that you have been facing.
If you have not yet reached out to us, could you kindly do so at 1300 30 70 37 on a weekday, any time between 7:30AM to 6PM (AEST), and we will assist you there.
Hi i have an optiflow unit outside balcony of my unit there was a noise that comes on and off like the water heating which is prob normal however as i was standing around that area thought there was a gas smell sort of checked a few times and it was on and off not sure though but can gas smell come from the unit when its reheating water???thankyou.
Robert B.Bosch Hot Water & Heating
Hi Stam, thanks for your question. All gas burning appliances discharge flue gases when combustion occurs. The gas you are smelling is probably this, however, we suggest you contact us to arrange for an authorised technician to inspect. To get in touch with an authorised service technician, please contact us at 1300 30 70 37 on a weekday, any time between 7:30AM to 6:00PM (AEST).
Hi. I bought an Optiflow 16 second hand. I thought I had got a good deal but reading the reviews I am thinking it may be a waste of money getting a plumber to install it. It is an older model. Were they any better?
We are on our THIRD optiflow. The first two had igniter issues and flow valve problems, all covered under warranty though. 7 call outs in total but Bosch have upgraded us to the Bluetooth model and ensured us the issue had been resolved in the factory. Ask yourself why the unit is second hand in the first place. Sorry to pee on your parade but unless it is under warranty, throw it away
