Useless for hot showers
I asked before installation if my mains water pressure was going to be good enough and was told it was... but I have had problems since day one - for 2+ years...
It is ok for hot water from the kitchen tap only as long as you are willing to run the tap at full pace and waste 20+ Liters before you start getting warm water, not sure how they gained the energy rating they did? but do not try to mix hot and cold at the same time - getting showers right is almost impossible
I have a 16H Bosch unit - it has been hit and miss since install as to i...f hot water will start. Now I have hot water starting no problem but as soon as I mix in cold water the back pressure seems to slow the flow of hot to the point that the burners stop and the hot water system supplies only cold. turn off the cold water and the hot - turn the hot back on and all is fine. If I leave another hot tap on I can see the hot pressure increase at that tap when I turn the cold on in the shower - like the cold is flooding back through the hot pipes. burner stays on only if a second tap is left running!

In reply to Julia.
Julia, you have to take the case off. A knob on each side at the back. Note how the cover goes back on. The knob controls the water flow. The way I set mine up is turn the hot in the shower if that's the main focus or at the kitchen sink to full open. Turn the knob in the heater untill you have the temp set to the maximum you want at the outlet.
This way if your washing the dishes you shouldn't need to add cold, but you will in the shower or vise a versa.
In summer/winter you might need to adjust at the tap or unit. I'm in Perth and set mine i...
There is a constant yellow flame burning inside the unit. My understanding is there is no pilot light so this is obviously leaking and very dangerous. Have disconnected until plumber can attend for the second time
No real issues
We have had this system for about 6 years. We previously had a storage water heater with pilot light. The bosch 16h uses much less gas.
It failed once with a water filter disintegration. That was because I failed to service the unit at the recommended 2 year intervals. We have no issues with it now. We have correct gas pressure, water pressure and water flow from the taps to ensure correct operation of the unit.
Also, our service technician really knows his stuff.

Issues With the HydroPower 16H
I had the 16H installed to replace an older Bosch heater that had started to leak. I had the same issue as others where it takes 3-6 attempts for the gas to light. Three days after installation I returned home to find both gas and water leaking from the unit. After discussions with the installer and the assessor sent from Bosch the unit was replaced. Three weeks later this unit still fails to ignite each time and, just now, the unit cut out mid shower.

Don't buy one of these!
We installed the Bosch 16H about five years ago and it's been trouble ever since with intermittent lighting. The spark works but it often does not light the gas. There seems to be no pattern with it - sometimes it lights first time, sometimes it takes several goes (so wasting water) to get going. Three plumbers have looked at it and can find no fault but they all agree that it is a very poor model that they receive many calls about for the same reason as us. I have contacted Bosch a number of times but they have either ignore my emails or sugge...st getting it looked at by a licenced Bosch repairer (which we have without any improvement). I suggest strongly that you should not consider buying this model. We have finally had enough of it and are replacing it next week with another brand.

unreliable and not recommended
Had Bosch 16H installed in 2010. In 2015, when I was away and the house was rented out it exploded. Luckily no one was hurt. No liability, no redress. As I was away, the real estate agent had their plumber replace it with the same Bosch 16 H. Having problems with this one too. In 2018 needed to pay for plumber to deal with inconsistent temperatures, and replace seals. Now it's leaking constantly, and I'll have to spend more money to fix (why bother?) or replace.
I will never buy a Bosch water heater again. How can plumbers install appliances ...

WARNING! STAY CLEAR !
Replaced my older Bosch unit with Bosch 13H and what an expensive mistake this is.
My water bill has sky rocketed, it takes so long for any hot water to make its way to the taps, and the unit is extremely close to the kitchen/bathrooms. The pilot turns off if you try to regulate the temperature to warm or if it’s placed on low pressure. I have been extremely frustrated with this product the day it was installed. Twice I’ve called Bosch and twice they have sent out the installers , basically all I get is that’s the way these new systems oper...

This is the perfect unit for someone who likes cold showers
Unit has a mind of its own . You waste a lot of water before it heats up then it fluctuates and doesnt hold heat , dont you dare use any other tap around the house for hot water it just isn't going to happen . Bosch makes other products that are beyond amazing but i think they should stay away from continous water systems . yes unit has been looked at and has been replaced . The only thing that I can say is that it is sitting outside my bin enjoying the sun and rust not much to say but shame on the person who designed this and went home and said what a machine i designed .this person is the devils cousin what a heap of rubbish stay clear you have been warned

Why is hydropower 10h making noise when not in use
Hydropower 10H is making noise when
Not in use, sounds like a fan I’d running. Is this a concern, or is it dangerous? It’s quite loud and can be heard In the back bedroom

Mistake I agree with Lucei, We purchased the 16H in 9/2015 and it has been intermittent with not lighting up consistantly since installation & has now not started after many tries. I checked & the ignition was sparking, but the gas not lighting. I rang the local dealer we purchased the unit from, who told me it was out of warranty and they are busy so I should ring a plumber! This I did and when they arrived and this time the unit started first time. We will be going elsewhere in the future.

Fixing ignition issue
I installed a hydropower 16h internal system 2years ago to replace an old Junkers water heater. In the recent a few months, I found it’s hard to be ignited, specially in wet days. Waiting for hot water without confidence is a headache when taking showers. Finally I decided to remove the cover to see what’s happening. I tried to turn on one hot water tap, the spark works fine, but pilot was not on. Then I switch the unit off and turned to on. When I had the second try it works. After a few hours, I did the same test. Similar problems happened ag...ain. I started to think there is something wrong with wire connections. Interesting thing is I found every time when I touch the connection wire in back side of the switch, the heater always can be ignited. Then I decided to cut the metal clip off, short circuit these two wires and bypass the switch. Since that, it hasn’t had issues anymore. I guess some sensors or even the electronic control box are sensitive to voltage. The turbine works fine, but when rust start to be seen on electronic components, it drops the voltage. Also Bosch is using aluminum wires instead of copper. The voltage drop became an issue to this water heater, even it is very minor.

Should be a class action, a piece of JUNK!!!
A big mistake choosing this hot water heater. It has never delivered really hot water, had the plumber out several times. Have contacted Bosch, always unhelpful. Today I had the Plumber ring Bosch and do trouble shooting with Bosch service team. Answer, nothing else can be done to improve the temperature of the water. Will have to continue having baths without needing any cold water, temp about 45 degrees, hopeless!! Also waste so much water, don't have mains water,only rain water from tanks, sometimes have to wait 5 minutes . Not good enough Bosch. DON"T BUY THIS PRODUCT.

Not Hot anymore but all is working. Bout month it has been like this
The unit is firing and gas is heating. But suddenly the past month my water is not Hot. I have just gone out and checked again ignition works fine gas is burning. By the time it gets to my taps I can hold my hand under it. I’ve turned everything up. But still warm to touch after running water (hot) for 4mins. Any one else have this.

Worst hot water system ever
Unit is a couple years old, consistently won’t light. Have to then wait for stupid lock out or have cold shower. Can’t wait to throw it in the tip and get something that works

Water temperature fluctuates wildly, too hot one minute, not heating water the next.
In March last year (2018) we had a failure in the heating coil in our Bosch 10P instant hot water service (after 20years of faithful service). I rang Origin Energy's replacement service (first mistake) who sent there plumber out to replace the original unit with a Bosch Hydroflo 16H instant hot water service.
We found that the hot and cold water flow couldn't be adjusted to give a comfortable shower, as our original unit had done. The mixed water temperature was either too hot or stone cold. In the warm weather when cold water inlet tempera...

Terrible, terrible, terrible
Purchased this unit in august 2018 as a replacement for our old bosch unit. We were advised by the installer that this was the one to get. We had the installation techs out four times in the first few days because it would cease to work. Despite my requests for a different unit it was inferred that the problem was user error !!!! SIx months later the unit takes ages to heat ,goes boiling hot then cold and has to be restarted several times just to get a lukewarm shower. This product has a major design fault and is clearly not fit for sale. Will be replacing as soon as finances allow. Avoid this terrible product.
Trouble from the beginning.
Unrealibile ignition of both pilot and main burner. Works today but not tomorrow or even now but not in 1 hour. Very sensitive to water pressure. Inserted inline water filter which helped in blocking the filter in the unit. Fortunately we are not entirely reliant on this heater. Reading the other reviews would incline me to replace it rather than get it serviced.
Water waster, hot then cold
We recently moved into a rental home and cannot believe the performance of the hot water system. Although the unit is directly below the shower it may take up to 4 attempts and many litres of water for the very hot water to flow. The minute the very hot water comes through any attempt to adjust causes the shower to become cold.
The Bosch unit 16H needs to be avoided.
Worst decision ever!
Had to replace my old unit which didn't even last 10 years, stupidly settled on this model. Worst decision ever!! We've nicknamed the unit Katy Perry because it's hot then it's cold. This shower either inflicts 3rd degree burns or induces hypothermia, along the way it wastes a tonne of water. How can a gas hot water system run cold when only the hot water tap is on. Will replace as soon as I can afford to.

Questions & Answers
My 16H pilot flame ignites but doesn’t spread to main burners. I can ignite main burners with a bbq lighter .seems a bit of flame coming out of mesh( air intake?)under pilot light.This unit has been problematic and tried different pumps over the years.Any ideas? Cheers, Blair
the main flame is not starting because the system wants more water flow - if you stop the tap... wait 30 seconds and try again from completely off to full speed and even turn on a second tap - you may find that it will light.... if you are lucky - these units are useless :(
how to clean water valve on a hydro power 13 H
Our Bosch 13 ignites but the gas is not spreading so as to light up properly
This is because the system is not detecting sufficient flow of water. Turn the tap to max - if this does not work, then turn the tap off, wait 1 minute and turn it on to max as fast as you can... wait 60 seconds - watch as the system which claims to have a good energy rating wastes water.... if this does not work then turn all off again...
wait a minute - then turn on tap to max very quick - then go to another hot water tap and turn that one on as well to max.... - if this does not get you hot water then your water pressure is either not enough or your system is stuffed.
Do not try to turn the cold on at the same time until you have the hot working - and even when the hot works - be careful turning on the cold depending on your tap or shower attachments as this may slow the flow of hot enough to make the system shut down the burners again.
Sit back and watch your water bill and gas bill go through the roof even though these systems claim to be energy efficient.... obviously only under lab conditions with the perfect pressure.
Your other option is to take the cover off.
There are two user adjustable settings (at least on my 16H) - one shows 1 to 3 flame symbols - this is for adjusting the temperature from low to high flame... this can be increased for hotter water - but this is not your issue - you are not getting enough gas to light the main jets, only the pilot light...
the second adjustment is a knob below the slider - this adjust the flow of gas in general - turn this to max - get some one inside to turn on hot water to full - watch and see if it now lights.
if this worked you may then need to turn it back a little and or adjust the slider so that your hot water when it actually works is not dangerously hot.
