Skotasked

Infinity 26

Hi
Ignition on the unit is intermittent, sometimes it lights up , sometimes not. Removing the gas line-in and reconnecting it straight away is the only solution at the moment. Air lock , perhaps?

Thank you for the question.

The units safety components appear to have been activated to protect the unit in this instance and will require a service call to reset the hot water system. Please call Service on 1300 555 545 or alternatively you may book on line following the link provided /www.rinnai.com.au/support-resources/online-service-booking/

Maureen Sasked

Infinity 26

Our unit is approx 14 years old and we are now having trouble adjusting the temperature. It won't let me set it below 37 degrees and if you turn on the cold water up to about half way the hot water goes off and you have to turn off the cold water and wait for the water to heat again. Very frustrating. Wouldn't be so bad if it was winter but at the moment we don't want really hot showers.

Hi Maureen S,

Thanks for the question. The issue may be related to elevated incoming water temperatures, may we suggest reducing the temperature to 42/40 degrees and test if this is successful. If the issue continues please contact our technical help desk on 1300 555 545 for further assistance.

Thanks,
Rinnai Australia.

Thanks for the quick response. I have dropped the temperature to 37 degrees but that hasn't helped. I can't get it to go any lower, should it go below this?

Rinnai
Rinnai A.Rinnai

Hi Maureen S,

Thanks for the question. As mentioned previously the incoming water temperatures may be elevated considering the current climate. Given the age of the unit, it may require a service call as the water sensors and filter may need to be replaced.

Please forward your contact details by private message and we can have a technical help desk representative contact you directly or alternatively contact the technical help desk on 1300 555 545 for further assistance.

Thanks,
Rinnai Australia.

Peterasked

Infinity 20

I just had a new Finnair 20 installed with 3 remote controls.
When I set the temperature at 37, it heats up to about 39 then the little gas symbol turns out and the temperature drops to about 30.
Then it heats up again, then it shuts off, then heats up, then shuts off.
The result is the water temperature fluctuating like a yo-yo from 39 to 30 for the whole shower.
What can I do to make it a constant 37 ?

Infinity 16

We have the rinnai 16 system and for some reason it keep changing ing the set temperature from 48 to 19 when you turn the hot water on. We have checked the gas and box and the power point is working. We have turned it off and left it for an hour but that didn’t help. What do you think the issue may be?

We have the same problem and I found the technical dept unhelpful. The person spoke in technical terms that I didn’t fully understand. The only solution I have found is to have another hot tap running at the same time which is unsatisfactory as it is a waste of precious resources.


Sue

Sueasked

Infinity 26

We have a Rinnai Infinity 26 water heater. It is 11 years old. For the last year it has had a problem of not heating the water all the time. I can be having a shower & all of a sudden it will go cold. Sometimes if I turn the tap off, then on again, it will start to heat again. Do you have an answer as to why this may be happening? It’s in our holiday house, at the beach, so doesn’t get used constantly.

Thanks for the question Sue. It may be an issue with water flow through the unit which can be restricted by a few things. Checking the filter on the bottom of the unit for debris or build up, or in the shower head. Our technical team can advise how to clear the filter and are available on 1300 555 545 option 3.

Thanks for the question Roger, the Infinity range of hot water units do not have a pilot light, the ignition is run from an electronic igniter.

If you are experiencing no hot water there may be another issue present. Our technical help desk is available on 1300 555 545 option 3 and may be able to troubleshoot with you.

What's the minimum flow rate shower head that can be used for this system? Would it work without hot water cutting out with a 9L/min shower head? Or do you have to use high flow?

3 answers
Rinnai
Rinnai A.Rinnai

Hi MsRachel,

Thanks for the question.

The Rinnai 20 is compatible with low flow rated shower fixtures (3 Star 7.0 to 9.0 l/min).
If you need more help you can contact our Technical help desk on 1300 555 545 option 3 for further details.

Thanks,
Rinnai Australia

Ok thanks.
We had one installed in August and everything was great. We have 2 bathrooms, both using 9L/min shower heads. No problems. But 3 and a half months later, we had a gas field audit where someone came out to test to make sure everything was installed properly (not initiated by us but by the officer of the technical regulator) and ever since then, both showers have hadissues every day with hot water cutting out. The orange light on the control unit goes out and the water turns freezing without any other taps being turned on. It is not a fault with the control unit - the water turns freezing when the orange light goes off. This has been happening in the hot weather as well as at 6am when the temperature has been below 20 all night. My husband has contacted the auditor, gasworks, and today Rinnai, and everyone keeps making excuses (it's the weather [which we know it isn't if it does the same at 6am], it's the low flow shower head [you yourself said 7 to 9L/min so that's an obvious lie]). If we get someone out, we may have to pay and we shouldn't have to because everything was perfect for 3 and a half months, yet the auditor claims they did nothing to cause it, and the others say it's the shower heads. They are the same shower heads we had since it was installed. I'm not impressed at all. We shouldn't be financially responsible for getting the issue checked when it's not our fault, and it's so easy to blame the shower heads to make us pay for it. Shame on your company for saying we can use 7 to 9L shower heads but blaming us for having low flow heads when the heat switches off constantly.

We have an Rinnai Infinity 26 and for the last few weeks, the temperature wont move from 42oC, the machine makes an constant clicking noise while the water is running and the water itself goes from hot to luke warm. While it is running the control panel also flicks on and off in conjunction with the clicking noise. Hoping you can assist.

Firstly I would check that the shower outlets are within Rinnai specifications.
Secondly replace the shower tapwashers.
If all fails then call Rinnai Service Agent for a needed Service call.
Have you recently replaced the shower outlets
Without the complete picture of your fault I can only make a keep it simple stupid aprouch.

Hi Rosetta S,

Thanks for the question.

As Peter Kothstein has kindly mentioned, Rinnai Australia agree and recommend checking the shower outlets and replacing shower tap washers.

If the above does not resolve the issue we recommend a service call to check that the water flow servo valve is working and check the incoming gas pressure.

Thanks for the question, we would recommend contacting our Sales Department to discuss this matter. They can be reached on 1300 555 545 (option 1).

Peter.K.

Hello Mark,

A Rinnai 16 is recommended for a single bathroom.

If you intend to do renovations may I suggest you purchase a Rinnai Infinity 20 or B20 which is recommended for big 1 bathroom Home up to 2 bathrooms.
The difference is approximately $100 between a B16 to a B20.
The gas consumption of a Rinnai B16 is 124 MJ/hr and a Rinnai B20 is 156 MJ/hr.
Ensure that your gas supply can deliver the minimum gas consumption or the unit will not work to specifications

Ensure your Plumber/Gasfitter gets a minimum of 1.13KPA at the gas connection test point or the unit will not work to specifications.
Commissioning of the unit is the key to years of trouble free operation.

Rinnai Australia now offers extended warranty on heat exchanger subject to you subscribe to Rinnai to carry out a Rinnai technician Service every 5 years, so for a builder's series unit 5 and 10 years extending heat exchanger warranty to 15 years on part only.

If you get a 60 degree unit, a controller is required for the bathroom to comply with 50 degree Australian Standards.
2 or more controllers installed extending your parts and labour warranty by 2 years to 5 years.

If you have any questions please feel free to contact me.

Regards

We have had no power for three days and therefore no hot water. As there is no pilot light for infinity 24, is there any way to manually light it?

Hi Peter H,

Thanks for the question.

As the infinity is fitted with an electrical ignition, power is required. Once the power is restored the unit will commence operation when a tap is opened.
