Has been getting colder for the last few years so technically only lasted 5 years before having problems. Water temperature doesn't keeps fluctuating so your constantly having to adjust between hot and cold. If you have a water save tap it doesn't even kick in to turn on the hot water so I can't get hot water out of my bathroom tap and never have been able to. Don't waste your money.

Bought this 7 years ago and has finally died. After 5 years in service the heat exchanger blew a hole allowing water to escape, Bosch covered the cost of the part but labour was at my expense. Then the water adjustment valve leaked and had to have that repaired. Unit allows fluctuated with heating the water. Cabinet is totally rusted. Updated to a rheem metro 16. When i asked about direct replacement unit for Bosch they recommended the rheem over Bosch.
Good better Bosch? Don't think so

Our water bill has doubled since changing to Bosch HydroPower. Water can sometimes take several minutes to get hot, other times water gets lukewarm then goes cold again so you wait another few minutes for water to heat up. Really annoying when you're rushing to work in the morning & you have to wait several minutes for hot water. Warranty is useless too. Plumbing & Gas Guys will charge me $150.00 call out fee & Bosch will also charge me $155.00 call out fee. Warranty is non existent, Bosch is only interested in being paid, customer service doesn't exist either

Extremely difficult to balance water temperature in shower; hot water often cuts out altogether. Spent so much time and hassle adjusting water temp/flow at unit. (Had nothing to compare its performance with as hot water system had to be replaced soon after purchasing home) NOW I know where the problem lies after reading a previous review here! (Incidentally, due to this I placed my elderly father in a hursing home earlier than necessary ... trying to help him shower became a sheer nightmare. Finding this out years later, I'm very upset!

The units give very little trouble, the power igniter and pilot jet are the only 2 things that ever have given trouble in 15y.o units. They are getting a bit rusty now so will buy new units exactly the same.
They are very simple for most handy men to repair.
I can diagnose most problems in a few 2nds amd most is to do with dirty gas.

We've had a 16H for about 17 years. It has been serviced once in that time. We've never had any trouble to speak of. Very occasionally it doesn't start first time, but you just turn off the tap and turn it back on and it starts okay. This might happen perhaps once or twice a year. For us living on solar power (no mains) it has been perfect.

We have had the system for a few years now so it maybe an older model. But it has broken down many times it has been expensive to repair. I often have to let the shower run for 2 minutes or more before the hot water comes through. In winter it takes ages for the water to be hot rather than just Luke warm. I need a new machine and I would never get one like this again.

Our hydropower 16 has been a dream. 14 years of reliable service. On a farm with no mains power, heating water is a dream with an lpg tank. we recently had a plastic part split in the frost. Time will tell whether bosch can assist with the part. I am hopeful though.

I bought a 100 acre farm with a renovated farm house and a Bosch 16H LPG Hotwater system 12 months ago. Been nothing but a failure and an expensive gas guzzling failure at that for 12 months. Like a lot of Bosch products it is a disappointment. Avoid avoid avoid.

Had this 16H since we bought house three years ago. Never sure if it will supply hot water. Had plumber come out who said he supplied a new part for $105 then couldnt get unit to go. He then suggested we get the pressure pump se4viced. As he left the yard I notice he had an old 16H gutted on the back of his ute. NEW PART, HMMM! Had service done on pressure pump still no hot water. After hefty plumbers bill and after reading comments might cut losses and get another brand.

this is the worst system ever! Uses load of water before it heats up and after 6 months after more plumbing costs than the system is worth HAVE HAD ENOUGH!!!!!!!!!!! So if you want to have constant misery and lots and lots of cold showers lpg BOSCH system Hydropower is for you......and DO NOT expect any help from the Bosch company !!!!!!!!!!!!!!.

This has replaced a previous Bosch Battery Driven unit. The advantage gained was when we lost mains power we were still able to have hot water and a cooking facility and no flat batteries. I recommend holding out for a unit like this and will install this in the next house I buy or build.

Have found this a great hot water system
Great hotwater works everytime
No messing with power or batteries to start it .
I have had no problems with it
At all.
Would recommend it to anyone that wants good hot water anytime .
I say great product so well built .

The Bosch HydroPower 16H is an excellent Hot Water unit due to on our farm we don't have much power so with the Bosch Hot Water unit you don't need power which is amazing. These Hot Water units are amazing and quiet cheap to run as per the specs on their website and on the operation instructions.

The valve that allows the diaphragm to open allowing gas to the main burner to flow is often blocked by grease applied during factory assembly
Follow the copper pipe from the hydrogenator to the grey housing at the front that has the flow control dial.
Pop the u clip and pull the pipe out inside the housing is a brass pipe pull this out with a pair of needle nose plyers clean the small holes and reassemble

I have a H 16 fresh out of the box. My pilot light turns on but the heating jets don't fire up so cold water is running out at more than 3,5 liter per minute. How can I fix this as no one is taking the blame for it?

Cheers

We are NOT affiliated with Bosch, nor do we frequently write a review. But ...
We recently purchased and had installed/certified a 16H Bosch hot water unit. Our new unit arrived from cross-country promptly and intact; it replaced a 10H model we had used for nearly 15 years. The new unit fired-up on the first go and continues to operate efficiently and without a hitch. Makes us wonder why our unit works so well, while some others here have tendered so many complaints. All we can write is: "Well done Bosch and thank you."
