Stops working in windy and wet conditions

published

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

published

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

published

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.

be very wary

published

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.

published

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,

published

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!

published

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!

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.

not a right answer

published

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

Not overly impressed

published

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.

published

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.

Absolutely terrible product

published

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!
