Manaaki

Manaakiasked

Infinity 24

I can hear the unit igniting or starting then suddenly stops. It heats the water for a second then switches off instantly. I try again and it always starts but doesn’t stay on. It’s as if there is either no gas going in for it to burn-which it has a full tank or the ignition to heat the water cuts out. I have tried many of the troubleshooting tips but none has worked. Does anyone know what Else I can try before I need to call a plumber. Thank you

Infinity 24

I bought a new controller for my Infinity 24. It is the BC 100 V deluxe controller. Unfortunately the Infinity 24 is not listed as a compatible system for this controller and it's not working. I plugged it in where the old controller went, and though the lights are on I can't control temperature using the new device. The small kitchen panel still works though. Is there a different controller that would be compatible?

Hi Annie,

Any heaters manufactured prior to January 2004 are not compatible with Deluxe Controllers due to the power consumption required by the advanced technology, which is why the lights display, but not any of the functions. While the MC601Q does not have the features of the Deluxe Controller, the technology is compatible with the Infinity 24.

Thanks,

Peteasked

Infinity 24

Mine is about 17 years old and is now not maintaining temp (hot to warm and back again). I have cleaned the inlet water filter and removed the water re-stricter from my shower head, which worked fine until recently and when removed made no difference. I have also listened to the gas flow during operation and no fluctuation noticed. We also have a temp controller in the bathroom. Wondering if it hot water unit needs replacing. Any idea what is going on? If I need to, do you recommended replacement model?

Ianasked

Infinity 24

I have a Rinnai 24 hot water system with a temperature controller downstairs and also upstairs. The transfer button on the upstairs unit has become faulty and inoperable. The model number is BC-45-3A and I would guess is over 10 years old.Can I get it repaired or replaced with the same panel or will I have to replace with another model, If so what is compatible?

Darrenasked

Infinity 24

I have a Rinnai 24, it periodically goes cold and the water temperature feels hotter than selected. (eg shower set at 41, but feels more like 50; after a couple of minutes the shower goes cold, then warms back up). Why is this?

Rinnai A.Rinnai

Hi Darren,

Thanks for getting in touch , we do have a 'Hot water cuts out' question on our FAQ's which may be able to help (https://www.rinnai.com.au/support-resources/faqs/) .

If not, the issue may be associated with the shower head and piping and you can get in contact with your local plumber.

Alternatively, you can get a technician to diagnose the issue which can be booked online https://www.rinnai.com.au/support-resources/online-service-booking/. If you need any further assistance please let us know.

Thanks,

Rinnai Australia

Gill Aasked

Infinity 24

Can an infinity system be fitted to a house built on a concrete base. We are considering buying a house with hot water cylinder but would want to have instant hot water system installed?

1 answer

Rinnai A.Rinnai

Thanks for the question Gill A, you can install an Infinity unit on a house built on a concrete base. You will need to ensure the pipe work for water and gas to the property is sufficient to run the unit. Your gas plumber will be able to confirm this.


Tux

Tuxasked

Infinity 24

Hi we have a infinity 24 and just recently it has been making a loud tapping noise a few seconds after the hot water has been turned off. Sounds like someone using a hammer. Any ideas what could be causing this?

1 answer
Rinnai
Rinnai A.Rinnai

Thank you for the question Tux, A Pressure Reducing Valve can alleviate water hammer issues. Water hammer can also occur when water pressure is too high. Installing water pressure regulators can solve water hammer issues due to water pressure. We would suggest referring to your local Plumber to help resolve this issue for you.

Where is the pilot light location on a rinnai 24?

1 answer
Rinnai
Rinnai A.Rinnai

Thank you for the question Khupa M. The burner lights automatically when the hot water tap is opened, and goes out when the tap is closed. Ignition is electronic, so there is no pilot light. When the hot water tap is off, no gas is used.

Hi Al B,

This is a very good question. I am aware that washing machines and dishwashers can have issues with heavy water. The best people to ask are the manufacturers.

Infinity 24

I have just brought a place which has an infinity 24, it's approx 13 years old. it's a 3 bed & 3 bath house but we can only use one shower with hot water at a time. Whats going on? is this normal?

1 answer
Fred
Fred

This may or may not be the issue for you but here goes - we had one shower that would not deliver hot water while others did - we cleaned out the filter on the Rinnai (Youtube tells you how) and it did not help; it turns out that the combination of a flow reducing device in the shower head and some clogging up with debris in the shower head was causing the water flow from the shower head to be too low to start up the heater. Once the flow reducing device and debris were removed form etc shower head, the hot water flowed well.
