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

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.

Useless
Purchased the 10h to replace the old unit which serviced the property for well over 10 years..... this was my first mistake to believe the replacement unit would be just as reliable WRONG. Hot water only works for 20mins per day then nothing until the next day..... called the plumber who advised a faulty part was the problem and since the unit was still under warranty it was best to call Bosch.... that's when the fun really began their "authorised/trained" plumber advied there was not enough gas pressure to the unit and it was not covered by w...Read more
arranty and the $220 fee was payable but it was not in their work scope to fix the unit.. Bosch customer service had no idea the status of my warranty claim....... now still waiting for a resolution after weeks of no hot water..... how can a unit work perfectly fine for 23 months and suddenly have developed external issues that prevent the unit from functioning as intended..... is it too much to ask for a unit to function as intended within the warranty period.... will never buy a Bosch again...... as for the authorised plumber apart from changing the reason for malfunction several times the lastest reason is the unit is not sufficient for the house size not sure about others but my house did not grow in the past 23 months...... Bosch honour your warranty and fix the unit...1 comment

easy fix for my problem
Cold mornings and lukewarm water, could only just stand the temperature when taking a shower, had to boil the electric kettle to be able to do the dish washing. Thought it might have been the caused by the exposed hot water pipes and the distance from the heater to the bathroom. Went to the expense and work by placing insulation tubing around the pipes, this lifted the temperature by a couple of degrees but still lukewarm, gave up and called local gas fitter/plumber. He was there for 15 minutes, took out the jets which were badly blocked, clean...Read more
ed them and voila steaming hot water! and he only charged me 20 dollars! I had noticed I was not using much gas from my LPG gas cylinder now I know why, he said the other problem can be the water filter blocking up on the inlet pipe especially if you are not on mains supply, Hope this helps someone.Similar opinion?

Hot then Cold Problem Solved
It took me two years and the cost of a new heater to sort out this problem. First 10H was becoming problematic in that the water would be hot and then suddenly cold. It didn't matter what settings were adjusted ie. flow rate, temp setting. A service man charged me $100 to tell me to put the water on the lowest flow rate and the temp on highest setting. Works ok in winter but not in summer. There was more to it than simple adjustment. I bought a new heater after a two seasons of this frustration. The problem still existed. It took some time to r...Read more
ealise the problem was caused by a new water restricted shower rose I put in two years ago. If you want these heaters to work remove all devices that restrict water flow. This includes shower roses, aerators on kitchen spouts etc. You will solve your problem.Similar opinion? Write a review on ieatwords.com.au!
Product has electrical fault (ghost)
The Bosch Hydropower units have poor electrical design, anyway assuming the heater is working properly, I would get it serviced for this that is <(TURN OFF GAS>), backflush water circuit, just unplug in and out water pipes and connect a hose to the outlet its easy enough to find a fitting or something, but you may need to bend the pipes around a little but do not hurt them!, the crud buildup in the pipes will reduce your efficiency like if you use it with unfiltered rain tank water you would want to clean it about every 5 years on the other han...Read more
d if you have hard water as in bore water then I dont know but I think calcium buildup will be your problem. hard water clogs up everything, disassemble and clean out water inlet manifold, there is a mesh screen in there, on mine it was in bits all through the ports clogging everything up. Now if needed clean over the whole unit with compressed air to spruce it up and reduce fire hazard or if your diy then it's nice to clean things before working on them imo. Don't ask me what all that would cost! You don't need to mess round with the gas side that's all fine. Now here's what you do to fix em, this is for a Bosch Hydropower 10H but I assume it probably applies to the other hydropower models too. Ok for those wanting more information the water flow runs the electronics @ 1.5v DC wich charges the high voltage pilot igniter but it also runs the 2 solenoids for the pilot gas circuit and that pilot circuit operates the diaphragm for the main gas valve. The thing is those 2 little solenoids are grounded through the whole unit, if you look it,s not great, so what I did was add a piece of wire say 5 amp should be heaps, now connect the wire to the fixing point for ground next to the electrical box and now connect the other end to one of the chunky screws that holds on one of the gas solenoids(DON'T REMOVE SOLENOIDS UNLESS YOUR REPLACING THEM THEY ARE VERY FRAGILE AND DON'T ABSOLUTELY DON'T UNSCREW THE SCREWS ON THE LITTLE COLORED PLASTIC BIT, That said I used the green one at the back, don't worry it wont leak gas as long as you only remove one screw but of course (>TURN OFF THE GAS<). Tighten up all the screws, again it doesnt hurt to go over the unit and check all the screws and bolts, there is one screw for calibrating the sliding knob also. And that's it turn on the gas and water and go test your brand new water heater! More info, you can test the generator with a multimeter, just unplug it and test the voltage with the water running through it obviously. Mine was about 1.6v You could also test the resistance of the gas solenoids with and without extra wire, etc. Fyi there is a brass screw about half way up on the left side of the unit facing out that I use to bleed the gas line, at least that's what I use it for. Just unscrew it a bit while its trying to light you just have to flick the switch a few times until the gas comes through then screw it up again. Also it doesn't hurt to go over everything with some soapy water in a sprayer to check for gas leaks especially if unit is old or if you can smell gas, I imagine if there was a gas leak inside the cover that would cause some issues. Anyway you wont believe how well it works after this mod, it ALWAYS starts as long as u have gas, it will stay lit at pretty low flow levels so you can mess round with the cold tap and it wont cut out to a point, I used to just have the cover off cos I was always messing with it trying to get it to light or tuning the knobs man it drove me nuts. Now I just leave it at the mid point between my summer and winter settings. I also disconnected the lights to help it work better but I think that's overkill. You don't really need to blast the hot tap anymore if you have enough flow it will just come on.Similar opinion? Write a review on ieatwords.com.au!

Waste of time and money, zero stars
Bosch Bosch Bosch!!!! Where did it all go wrong!!!! We have had this unit for 7 years and in that time the only time I get a relaxing shower is when I’m not at home. The water goes from hot to cold constantly, when it is hot it is too hot and then when you ease the cold up enough and the temperature is okay, it will last for about 10 seconds and then go cold. I have adjusted the water flow and gas flow plenty of times but as soon as the weather changes ( which happens in Melbourne all the time) the water will be too hot or too cold so you have ...Read more
go adjust it again and that’s just on the days when you can get it started. There was also a problem with it where you would turn the hot water on and then off and it was like a bomb going off down the side of the house. The only reason that I have kept this piece of garbage for so long is because we are a single income family and with a mountain of bills every week it makes it hard to replace a “working” unit, but when we have some spare money I can’t wait to get a Rinnai and forget all about this lemon, I can’t believe that Bosch are still selling these things. They won’t be getting my money again!!! So if you’re still reading my rant, do yourself a favor and don’t buy one of these things. I have used the rinnai units a few times and they are great, 100 times better than my dud.Similar opinion? Write a review on ieatwords.com.au!
Don’t ever buy a Bosch gas hot water system. Mine didn’t last 7 years when the hydro failed
If you are looking to install or fix a Bosch hot water system I recommend scrapping you unit and replacing it with a reliable brand. Our gas fitter sourced $270 worth of parts to replace the hydropower and to refurb the main chamber, this didn’t work so the unit had to be scrapped. This cost a considerable amount of money. We would have been much better off to replace the unit as soon as it failed with a reliable brand.

Five years of uninterrupted hot water
How can there be so many complaints from so many people?? We've had this system running flawlessly in Melbourne since July 2012. The distance from the gas meter to the Bosch unit is over 20 metres yet there's enough pressure to run a hot shower with the gas ducting heating in winter. Extremely pleased with this super reliable product and would not hesitate to recommend.

LEMON!! Absolute rubbish product! If you like cold water this is for you! 0 stars!
Absolute GARBAGE product! From day one it broke down & since then numerous visits from plumbers trying to fix the damn thing! Nothing but trouble! 4.5 years & we are up for a new one. $1400 for nothing but an overpriced wall hanging! Customer service was very average. Kept getting excuses of ants or insects blocking the pipes! Well I'm with the plumber now & no ants just a piece of crap! Wish i had reviewed this product sooner as there is obviously a lot of ant problems about! LEMON!!!

never starts
bought this for my outback property years ago and has never worked properly. it's alright when it's being used every day but if not used for several months won't ignite, takes constant switching on and off to get it started and sometimes not at all. sometimes the ignitor works sometimes it doesn't. I ended up smashing it to pieces with a hammer. The trouble is what do I buy? reviews from other brands are no better.?????

Great Unit
I had this unit installed in 2012 and it is still going well, I find it better to turn the water off to the unit when I go away and it fires up every time, it may be getting a little tired and when it does give up, I will replace it with another one.
February 5th 2017 Update: Hydropower 10h HWS
I made an error with my previous review, I actually had it installed in 2002 and it is still going well.I believe that the later models are much more efficient.A lot of people make the mistake of trying to adjust the Hot Water with the Hot water tap, you actually adjust the cold tap.

Dreadful engineering
We got this unit as a replacement hot water system for my 80+ year old mother around a year ago and it's been nothing but trouble since. In theory this is a good idea - the flow of the water ignites the flame for the instantaneous hot water. In practice, it's dreadful. Months of pouring litre after litre of fresh water down the sink dozens of times a day waiting for the water to come hot, who knows how many thousands of litres in total. It would take multiple attempts to ignite, turning the hot water taps on and off again and again. It would co...Read more
me on and shortly after go back off. Multiple adjustments to the flow in the system to try to get it to run. Just awful to use. Service calls from the installer saw little improvement, and when winter hit things just got worse, with my elderly mother at times reduced to heating water in a kettle or on the stove to wash with, just like going back her pre-hot-water childhood. Finally in August the installers came and did a major internal overhaul of the system, and said that a design fault had been found and this should rectify it. Well the system did become more usable after this at least, but now having come by the house at Christmas I find big black carbon deposits have spewed out of the vents of the unit, up the bricks on the surrounding wall, and onto the eaves above. Who even knows what is wrong with the system to cause this, I've never seen anything like it in a natural gas system. It may even be quite dangerous to be using. So it will be another call out for the installers once they re-open after xmas, and we will undoubtedly be footing the bill for the clean up and repainting that the system has now caused. This system is an absolute mess and I struggle to see how it's still on the market - Bosch should hang their heads in shame for selling such a product. I know they will refuse, but I will be requesting a replacement system when I call out the installers again. If you're looking to buy there's plenty of other systems on the market that have to be much better - don't let them talk you into one of these.Similar opinion? Write a review on ieatwords.com.au!

It doesn't work as intended
I can't run hot and cold water at the same time with this heater. If I turn on the cold water tap when running the hot, the heater unit cuts out and you only get cold water. It's been like that since day one. This is not like other Hot Water units I've had. Buyer Beware.

EDIT 15/6/17 - 10yr old issues after 5yrs.
It's ok. After 5 yrs some issues with pilot light starts. We constantly had to try to clean it and brush any cobwebs away as spiders love the ignition box and pilot flint. Sometimes it's frustrating to go in and out seeing what we could do. The pilot light was big issue. Had to light it with lighter every now then.
Serviced twice in 2013 for a worn pilot light and dead spider ($289 + $150). Recently nov 2016 for a new ignition box ($404) and wasn't informed about the replacement or costs of it until I received bill. Then in feb/17 anoth...Read more
er part broke for $320. Unbelievable. They could have called to give option as a NEW fully installed unit or even better a RHEAM was $1000-1200. Perth Gas Service has a monopoly to servicing the Bosch 10H in Perth area. Don't know if that's still the case but I don't recommend them as you have no other option. Overall after 5yrs you get issues and frustration. After 8-10 don't keep servicing. REPLACE.Similar opinion? Write a review on ieatwords.com.au!

Absolutely rubbish. In the 1st two years of warranty, replaced ignition system, burner, heat exchanger and diaphragm. Works great in summer but when it feels like in winter. Diaphragm area is all plastic and leaks and cracks. It lasted 4 yrs.
Got a 10P yes 10P... Absolutely robust built, all brass around the diaphragm and way too hot. Got the water flow half way set as fully in too hot to shower with even cold water opened.
The 10H never even got that hot from brand new, even after the bosch tech looked at it 4 times during warranty.

Questions & Answers
Laraasked
my system works fine during the day, but at night it is very hard to get the system to work. all I can hear is the clicking which cuts out after about 10secs. I have to turn the taps on and off many many times, each time checking to see if it has lit. Eventually it does light up. But this is so annoying. I have skipped having a night time shower for several years, but I no longer have that option. Hoping that this is a simple problem to fix?

IV just moved into a flat and have no hot water. If pilot light is automatic how do I start it. There is no red or green light on at all.

Turn on the gas supply, water supply and a couple of hot water Fawcett's. When you do have a listen to the unit to see if it's fired up.
If not call the real estate agent or owner as it's their responsibility.
I turned everything off for hour then turned tap inside on then gas then water and it started straight away thanks
