HydroPower 16H

How do I light it

Hello

David
David

The unit should light when you start water flow through the hot tap. When you open a hot water tap the flow starts & the igniter starts sparking which you would hear if you listen at the heater. We have found that the ignition sparks but the unit is spasmodic at starting and we now turn on one or more taps to get maximum water flow and it mostly starts after about 5 to 20 times. We are almost at the point of replacing with another make of unit and dread the arrival of our next water bill.

how do you turn hot water temperature up

Sorry but the unit is rubbish, I have had three plumbers in to try and get hot water but all say there is nothing they can do. They have contacted the Bosch technical team and spoken to them while they were here and the answer by the technical side was there was nothing more that could be done. The unit is useless.

We cannot turn the temperature up more than maximum on the unit, I have a shower on full heat! We have to turn the tap on a number of times to get the heater to work. I will never buy another Bosch product.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Richie, thanks for your question. Please be informed that a few alterations can be made to increase the hot water temperature.

Inside the unit there are 2 temperature adjustments that can be made: a slide control that controls the gas burner and a round dial on the water valve. Slide the control to the right to increase the burner and temperature, you can also turn the round dial clockwise to increase the temperature.

If these are already set to the maximum settings, then a service is required. Services are recommended every 2 years. If you need assistance with getting in touch with an approved service agent, please call us at 1300 30 70 37 any time between 7:30AM and 6PM (AEST) on a weekday.

HydroPower 16H

Our hot water went out yesterday and we cannot get a gas fitter till who knows when. It clicks but no hot water. What do we do?

Robert B.Bosch Hot Water & Heating

Hi Samantha, we're sorry to hear about the issues that you're facing with your unit.

The unit has most likely locked out due to a failure to ignite. We suggest that you turn off all the hot water taps and try again. If the unit still doesn't work, you will need to isolate the valves at the unit for 20 seconds, then reopen the valves and try again.

If the unit still won't work, we suggest that you refer to a qualified service technician by getting in touch with us at 1300 30 70 37 any time between 8:30am to 6:00pm (AEST) from Monday to Friday.

Hello,
Our. Bosb hydropower 16H is not heating. We have turned the hot water on for awhile to see if it reignites and nothing happens. Gas is ok, what else could be going wrong?

I don’t know what the part is called but it was a $300 fix . like a thermostat but wasn’t called that... it’s role was to generate the gas flow into the box. Which was broken and slowed the flow of gas hence why it would not heat up

Thanks Thos could be the issue we are booking a service on it.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Damo, thank you for your question, we're sorry to hear about the issues that you are currently experiencing.
It is likely that the unit has locked out due to the failure to reignite as you mentioned. You will need to turn off all hot water taps and try again.
If it still does not reignite, then isolate the valves at the unit for 20 seconds. Then open and retry.
If after this it still fails to ignite, please refer to a qualified technician, our friendly customer service team can assist you. Please get in touch at 1300 30 70 37 any time from 8am to 6pm (AEST) during the weekday to assist you.

HydroPower 10H

How do I light the pilot light?

1 answer
Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Taryn, thank you for your question. The ignition for this unit is automatic.

If the ignition fails to ignite after 20 seconds, this will trigger a lockout mechanism. In this case, we would suggest that you turn off all hot water taps and try again. If the unit still doesn't work, then isolate the valves at the unit for 20 seconds, then open the valves and retry. If after this, the unit still fails to ignite, please get in touch with us at 1300 30 70 37 any time from 7:30am to 6pm (AEST), so we can refer you to a Bosch qualified technician.

Please be advised that we do recommend that our units are to be serviced at least every two years so your unit may be due for a service.

HydroPower 16H

Our bosch 16H has been playing up, the water is only warm and when we have a shower i turn the hot tap on its only warm and when i turn on the cold the hws cuts out and both taps deliver cold, the flames go out as soon as i turn the cold on, is this a flow issue? The house is on rainwater only and we have a Davey HS50-06T pump which is supposed to be more than adequate to supply our house

Sorry , no idea, can't even solve my issue with the unit. Have spoken to many Plumbers who said Bosch won't admit fault these days. Apparently they used to be very good but not now. I will be buying a Rinnai next time.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Paul, thank you for your question. It's great to hear that you have a constant pressure pump as we do recommend one for the HydroPower unit.

Based on your description, we believe it could be a flow issue. As it sounds like this only happens when you shower, we would advise you to check for any flow restrictors as we recommend using shower heads with a flow rate of 9L/min. Also dependant on the age, it could be due for a general service. It is recommended that all gas burning appliances are serviced at regular intervals. Bosch recommend every 2 years.

For further troubleshooting, please get in touch with us at 1300 30 70 37. Our line is toll-free and we are available from 7:30am to 6:00pm (AEST) Monday to Friday.

We recently had an issue with the 13H. When you turn the hot water on make sure you can hear the water turbine whirring fast. You can sometimes get debris caught in the bypass valve that is in the turbine assembly which jambs it open severely reducing its speed and voltage output. It simply shuts the gas solenoids off. The turbine assembly can be removed, dismantled, and cleaned out relatively easily.

Sorry no idea, can't make mine work but has other issues compared to yours.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi there, we suggest trying to "restart" the system as it could be due to air in the gas lines. Please follow this procedure: Turn off all your hot water taps and then turn one tap back on at full flow. Isolate the valves at the unit for twenty seconds before re-opening and trying the steps above again. If this does not work, please get in touch with us at 1300 30 70 37 as your unit may require some servicing.

HydroPower 16H

We live rural, our water supply comes from a header tank which is 30m higher than the house.
We want a continuous flow hot water system that is not dependent on mains power for ignition and will deliver better than 20L/minute at a temperature of 55 degrees or better.
We run LPG.
For the past 20 years we have had a Bosch 16B, but it is now becoming unreliable.
What do you suggest/recommend?

3 answers

Well, I recommend not to get anything like the Bosch Hydro power 16H. Even if the 16 H worked it would only deliver 16 litres /minute. I have been advised to get a Rinnai or a Rheem. Hope that helps.

Hi Andrew, please be advised that the direct replacement for the 16B is the 16H. Please be advised that the unit will not be able to deliver 20 litres per minute at 55°C but it is the largest non-powered unit available from Bosch.

HydroPower 10H

I bought a couple of these in 2015 for rental properties. The tenants haven't complained about the water temperature but the other day checking a water leak i notice that one of them has nearly rusted away. The other tenant confirmed that his was also rusty but I haven't checked that one. The rust is really bad, all over the unit, it looks like it won't last the year out. I'm not sure how long the warranty is or what I can do about this but surely they are meant to be outside and they were fitted by someone from the Gas Company who never said they needed cover.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Molly, we’re really sorry to hear about the issue you’re having with your units. This range has a full warranty of two years for parts and labour, and further warranty of 10 years for the heat exchanger part only. The level of corrosion within the time frame you are referring to sounds extreme and not normal. Although we do not know the location of your units, installation in areas near ocean or marine environments will cause premature corrosion of surface coatings. As such, we recommend in our product literature to avoid such installations as it is not covered under warranty. If you require any further information regarding our warranty conditions, please don't hesitate to get in touch with our team at our toll-free line 1300 30 70 37 (we are available from 7:30am to 6:00pm Monday to Friday). We also suggest getting in contact with your gas company regarding this issue.

We polished it up and put a wooden cover on it and it is ok now. We do live near the beach but the heater is on the other side of the building. Ga an company was no help.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Molly, thank you for clarifying the location of where your units are located. Unfortunately, the powder coated steel we use in our units can be affected by the salt content in the air of your environment. A slightly unorthodox method to slow down the corrosion would be to coat the unit in fish oil as a preventative measure. This product is typically called rust prevention/guard/treatment and will usually have fish oil in the product name. It can also be purchased from your local hardware store. As mentioned, it will not stop the rust from coming back, but it can help to slow down the corrosion. Please also be advised that due to safety concerns, we strongly recommend the removal of the wooden cover as it is a fire hazard.

G'day, we are going to replace our old gas hot water heater with a hydropower 16H, the old system has a regular between the bottle and the unit. Will that regular be needed for the new system, and if so should I be letting the installer know what type, pressure rating etc the existing regular is. We live a long way from town so I want to give him as much info as possible.

Hi Michael, thanks for your question and we apologise for the delayed response as we have been having issues with receiving notifications on this platform. Based on the brief details you have provided, we believe that this may be unsafe and may have the potential to cause personal injury and property damage. It could also be non-compliant and illegal, which also means that any servicing issues will not be carried out. We highly recommend that you get a second plumber to come out and inspect the installation. The plumber can make sure regulations are met in order to give approval for the unit’s installation.

I will shortly be purchasing a Bosch 10H as highly recommended by my Plumber.

This wlll replace my Bosch 10P which is 20-plus years old. In poor condition and rusty. Overall used to work well. Has now failed.

How does the 10P compare with the new 10H model?

Thanks, Maureen.

Bosch Hot Water & Heating
Robert B.Bosch Hot Water & Heating

Hi Maureen, thanks for your question. The Bosch Pilot uses a traditional standing pilot light while the Bosch HydroPower uses water movement to create its own small voltage to ignite the water heater. Please be advised that if you switch from a 10P to a 10H, you may notice a slight difference in performance. We would not recommend switching from a 10P to a 13H, for example, as there would be a significant difference in performance and hot water delivery. If you have any further questions, please get in touch with us at 1300 30 70 37 any time from 7:30am to 6:00pm (AEST) during the weekday and our helpful team will be able to assist you further.
