Bosch Optiflow 16L - flawed design
Bosch Optiflow 16L, installed October 2017. Heater won’t heat water when I want it to. Randomly operates when I don’t want it to (wakes me up early hours of morning - heater fitted next to bedroom). When it’s over 38C outside, heater operates randomly. This heater requires half a bucket worth of water to pass through it before it decides to operate. After 2.5 years of ownership, its internal cold water valve has become intermittently faulty (hot water randomly won’t flow). I am going try to fix/bypass faulty valve tomorrow (I’m not wasting my t...Read more
ime with Bosch tech support). To Bosch: I am a return customer. I previously owned a Bosch Hiflow16e I had installed in a previous house in 2009 and it operated flawlessly until I sold house - 9 years of 100% reliable use and it only operated when used. I moved into my new house in 2017, and replaced new house’s ageing boiler with a Bosch Optiflow 16L on the reputation of your Hiflow unit. To give you idea of how product loyal I was to Bosch, the plumber that installed my Optiflow unit, quoted me for a Rinnai heater (which I did not request) that was $300 cheaper than the Optiflow !. Your reputation is now in the bin, along with this heater when I save up the money to replace it. Maybe you can print this feedback out and use it as a case study in your next design meeting ?. Essential requirements: a) Has to use less an 1 litre of water to operate, b) reliable operation, c) Must operate in Australian conditions. d) Factor into your design that water heaters are fitted next to bedrooms. Many modern houses in Australia are like this with the master bedroom and the gas mains next to each other and a recess in the brick work for a heater (sorry, that’s just the way it is). Having a unit randomly operate at 3am in the morning and waking the occupant is a poor design, period.Purchased in October 2021 at Edward Skibicki for $2,145.00.

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

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.

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?

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...Read more
'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-T1E10 comments

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...Read more

Rubbish.
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...Read more
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.1 comment

Something wrong with the temperature. Either too hot or too cold
Something wrong with the temperature. The company gave me a replacement and the problem still there.! The Bluetooth app sounds fancy but it is not working properly most of the time. I wouldn't recommend it as it is not reliable enough and didn't meet my requirements for the ststem. Thank you.

Don't waste your money.
Nothing but dramas with this unit! We had the first one replaced within 6 months even though we had drama with it from day one but plumber wanted nothing to do with it. Replaced all piping and regulator trying to fix it but found out there was a whole batch that were faulty and we had one of them! Bosch knew the whole time that we had a faulty one (they had the faulty batch serial number) and they never let us know. After calling the plumber and Bosch repeatedly we finally had it replaced. But still don't recommend even with the new unit. So m...Read more
uch water gets wasted before it heats up. You can fill the kitchen sink to full before the water starts heating and you stand in a cold shower for a minute before it starts running warm which is great for the kids in winter! Also, ours is run off bottled gas and we have had some major issues when one bottle runs out and we need to switch to a new one. Have had air locks in the pipes that are a nightmare to get out. We purchased the extra temperature unit which you fit inside the house and it allows you to adjust the temperature, turn unit off and on and see any fault codes. In my opinion this should come with the unit considering how much it costs and shouldn't be an extra we have to pay for. Without it we wouldn't have been able to fix half the stuff ups this unit has had. Atleast we've had fault codes to refer to. All in all: don't waste your money. Nothing but a headache!Similar opinion? Write a review on ieatwords.com.au!
Nothing but trouble
I am so glad I rent, If I had had paid money for this unit I'd be irate. Nothing but issues, we are on the second unit, piping upgrade and the whole box and dice. Plumber reckons it is recording an over-temp fault in a constant loop. How could it overheat if the igniter isn't even activating. Absolute piece of rubbish. I do not recommend this product to my worst enemy.

Absolute rubbish - do not purchase bosch water heaters.
New optiflow 16, leaked water from one of the sensors immediately water was turned on. Faulty o ring found and replaced. Now a week old and has not worked properly from day one. Continually has to be reset and this only lasts until the hot water has to be used again. I have upgraded to a larger inlet pipe from my water pump in an attempt to get more pressure to the heater but to no avail. Gas and power has been checked and is correct. Wasted $820 on the unit and another $200 + upgrading pipes etc and still no working heater

Questions & Answers
Andreasked
Why has Bosch not recalled the Optiflow gas hot water system because it is doing the brand name considerable damage and costing its customers a fortune in having to buy reliable replacements?
1 answer
Because unless it's risk to life companies do not recall. If the unit you bought is NOT FIT FOR PURPOSE (delivering consistent flow and temp water) then under Consumer Law, the company needs to REPAIR or REPLACE or REFUND. If repair didn't work, they might suggest another repair (refuse) then they will either offer a replacement (within their rights) at their cost not tours, or refund. If you have already had a repair and a replacement and still do not have WHAT YOU PAID FOR (continuous flow and heated water) then put your foot down and scream REFUND. Also, losses (within reason) that you have incurred should be claimable, as long as they are directly caused by the unit not working, and as long as you have PROOF of those costs, but you may need to put your claim in legal terms and quote the legislation when putting in such a claim.
