Absolute piece of rubbish

published

Today is the 5th time a plumber/gas fitter has worked on this unit.
1. Fluctuating water temps and won't heat adequately
2. Trips the power box
3.Noisey and now randomly activates in the night
4. My electricity and water bill have almost doubled due to having to run so much water to get hot water at all, can't regulate the shower properly. Can hold my hand under hot water in kitchen as it is not hot enough and the system box is 1 metre away.
I would NEVER recommend this unit to anyone and if I could give Bosch 0 (Zero) stars, I would.
Not a company I would ever deal with if I had a choice again.
Many people in this village have had units replaced.
I am not participating in any giveaways or promotions. I am a disgruntled consumer.

Works sometimes but mostly not..... replaced under warranty but unit still no good, never again Bosch any other brand must be better than this unit. Please avoid even if the cheapest option.

A load of rubbish

published

This unit seriously is not good.
Its the 3rd unit I have had in various dwellings, and only this one is damn unreliable.
Its in a Holliday home in remote location and I think I will get it pulled out and get a different unit.
Only installed just over 12 months ago and it always switches off and needs re- booting.
Now thats not even working.
My main dwelling has a 15 year old unit going well.
The optiflow 26 is a complete load of crap.
Not good enough in this day and age.

Exceptionally bad unit

published

The unit stopped working two months after we moved into a brand new house. Found an online guide to fix it but couldn't get it to start again. Real estate to got someone out three days later and got it going. Since then I regularly stops working. Gas bill is now through the roof. Wastes so much water waiting for it to heat up. Worst unit I've ever come across.

Extremely disappointing

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!!!

published

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

Avoid like the plague!!!

published

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.

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

published

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.

One year of tepid water

published

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!

Needs restarting to make hot water

published

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?

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 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).
