Bosch HydroPower

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

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.

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

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.

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.

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.

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

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.

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.

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.

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.
