Rinnai Avenger 25 / 25Plus

Hi all I have had this gas heater for a while but there is an error, 12? why does it start to work but after a while turn off and show code 12? any comments? I cleaned filters and sensors though. thanks

I have owned both models of these heaters for several years. Never had an issue with either of them. I can honestly say I don’t find much difference between the 2 of them. One thing I will say to Rinnia is they should answer people’s questions when they are asking about one of their products instead of just posting a standard reply saying contact this department or that department. This is not good after purchase customer service.

The heater is in a large open space so virtually 3 rooms. Able to cope easily with heating up the rooms but it wasn't able to maintain a consistent temperature, heating to well over the set temperature. After a few calls to Rinnai support they suggested a few things and when that didn't work they scheduled a tech to come out and he looked at it and replaced the thermostat under warranty. Works a treat now. Would certainly recommend but you need to allow for some ventilation to the outside as its an unflued gas heater. The suppport was better than most organisations.

Hands down the most powerful heater I have ever owned. We have a very large open plan house with high ceilings and this heater heats our entire house within a few minutes. We have had ours for 8 years and it's still going strong, not a single problem. Before this we used to have multiple heaters and sit under the blankets until things warmed up, not with this. Has great features, simple to use and reliable. I wish more products were as good. Worth every cent and I'm normally very picky.

I have had my heater for a few years now, filters cleaned and serviced but smells like coffee when we turn it on? Why is that? Doesn't smell of gas.

Never liked gas for cooking. But this is different.
We now have 3 units. Vastly superior to aircon for heating an open area.
Very fast warm up time for an area. The walls may be cold, but who cares!
Contacted tech support with some technical questions. Got fast response.
Just note that these units do not actually switch off, irrespective of temperature setting.
So if you oversize the unit for a small room, you will fry.
The next advantage of gas is that you cannot overload the supply (nothing can trip).
1 year update - Just to confirm a couple

Heating wise, this heater is very good, heats my large open plan area very well.
I have marked it down because the advertised warranty is no quite factual. -https://www.rinnai.com.au/online/heating/portable-gas-heaters/avenger-25-convector/#!
It says "5 year peace of mind warrant""
When you look up the details, you find labor is only covered for 5 years, and a lot of other parts are less than 5 years.
Anyone who has bought this based on what is said on the web site will be entitled to 5 years warranty, however you will have to refer to Consumer

This is our first gas heater, we used a/c before buying the Avenger25 it was a bit more expensive than other brands but well worth it. Warms a large open plan area, very easily and quickly. Easy to operate as well. We run ours on economy most of the time and it does warm up well. Really like that there is no visible flame stopping children getting inquisitive. Would recommend without hesitation.
Like it so much have purchased 2 smaller Rinnai heaters for other family members.
