I now have to just use it without temperature control so adjust the water so it’s not boiling until we get a new one

Rinnai A.Rinnai

Hi Sean, thanks for the question. The Infinity hot water units will switch on as soon as you open a hot water outlet. The power, gas and water must all be on for this to occur.

If you are having issues, we have a technical help desk available on 1300 555 545 option 3 who may be able to assist.

Thanks

Thank you for your question.

The B-series was developed for the builders market and and the Infinity 20 is made for predominantly for the residential market and each offer a different warranty.

Ho do you increase the water temperature in this boiler

There is an orange cover over the temperature control screw. You should feel be a small tool tucked in one of the foam insulation. If you pull the orange cover off you can use the tool to adjust the temperature. Clock wise turn will increase the temperature. I hope this helps.

Rinnai
Rinnai A.Rinnai

Hi Mukesh, it will depend on the model of the unit if you can alter the temperature of the unit. You can find the model and serial number on a data plate on the left hand side of the unit. The model number will start with REU. Once you have this information you can contact our technical help desk and they can advise if the temperature can be adjusted.

Thanks

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 ?

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.

Infinity 20

I have water dripping from my rinnai 20 heater what can I do please

1 answer
Rinnai
Rinnai A.Rinnai

Thanks for the question Bob, if the water is coming directly from the unit and not the connections leading to it, there may be an issue with the heat exchanger. We would recommend booking a service call to have the unit assessed. In the meantime, if you can, isolate the water supply to the unit to prevent further damage,

Thanks

Hi, I am going away for 1 month. Will hot water unit be ok if I turn off water mains but leave electricity and gas on.

Rinnai A.Rinnai

Thanks for the question CMF, turning off the water to the unit will be fine as long as the power to the unit is still operational so the frost protection to the unit will still work.

Infinity 20

HI there, just wondering if a slight gas smell upon each start up is common with a B20 model? The smell ceases during operation.
Thanks
Rory

1 answer
Rinnai
Rinnai A.Rinnai

Thank you for the question Rory. The gas does enter the Infinity after the sparker is going, combustion should start almost instantly. There is likely to be a miniscule amount of unburnt gas able to be detected in the flue, just prior to combustion…hence the smell.

Just had a Rinnai B20 installed. The water comes out cold then goes hot and then continues the cold/hot cycle. Any idea what the problem is?

This is a normal issue. They will blame your low flow shower heads which is wrong considering they themselves say it can be used with 7L/min to 9L/min shower heads. Call them, make them do something, and if they blame your shower heads, take it further. That's what I'm doing.

Infinity 20

I have a two-storey house with one bathroom and a kitchenette downstairs; an ensuite, bathroom & main kitchen upstairs (so the main taps used are upstairs). I recently had to have my hot water system replaced & the tradesman installed a Rinnai B20. Is this unit sufficient for the needs of my household? I have also noticed that the hot water takes a long time to get hot & doesn't get very hot in the upstairs kitchen where i need it hot. Again, will this unit be sufficient and can i get the temperature increased so that it is hot upstairs?

I have been in my home for two years and it has a Rinnai 20 infinity hot water system! The home is an old home with a new Rene out the back! The unit looks like the older model! Tonight I can't get any hot water! It has been fantastic up until now! I went outside and there is water dripping outside of the unit, DOES THIS MEAN I NEED A NEW UNIT?
