Bosch Hot Water & Heating Optiflow Professional 20L

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 ...Read more
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 2021.

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 2021 for $730.00.

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.

Know better, choose better.
Don’t buy this unit. Try Rinnai instead
We bought this unit early 2018, plumber has been called twice the last 3 months, unit will not heat the water. Bought Bosch as it is a well known brand but in hindsight should of bought a Rinnai as our plumber has said that he has never encountered a problem with that brand

Biggest piece of trash I’ve ever bought
Replaced my old unit with an optiflow 20 professional and it packed up within months the tech guy has been and repaired it 3 times. The next time called out they replaced the unit. Not even a week later the new one has started playing up. I wish I could get my
Money back and buy a different brand. Not at all happy

Very Happy with the 20L
I needed to upgrade gas and water pipes to 20mm for this unit, and once installed has worked brilliantly.
The temp module works great with preset temps for showers.
Very surprised at the other poor reviews, I would of given 5 stars except finding the fan that cools the unit turning off and on all day, I guess due to radiant heat slightly annoying.
Apart from that I highly recommend!
Prior unit was a Bosch 10p which worked well for 20 yrs!
This unit now 6mths old.
Ok, Bosch sent a tech out, seems that the original installer did not do the initial setup properly.
So no more intermittent noise from water sensor adjusting itself and working like a charm!

Questions & Answers
Henryasked
Is the set temperature meant to flash non stop when the unit is heating the water or make a humming sound after the tap is turned off
1 answer
Robert B.Bosch Hot Water & Heating
Hi Henry, the temperature flashing means the appliance is not delivering the set temperature. Once the unit is delivering the set temperature, it will stop flashing. The buzzing you hear after the tap is turned off is the water valve adjusting to optimal position for the next hot water usage. We hope this is helpful and if you have any further questions, please don't hesitate to contact our friendly team at 1300 30 70 37 any time during the weekday from 7:30am to 6pm (AEST).
