Rinnai Avenger 25

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.

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).

I used gas for the first time last winter and would not go back. I bought a Rinnai Avenger as quite a few plumbers said they were the best gas heaters. I have a 3 bedroom home and there was no drama keeping the living areas warm. Best bit was setting the timer to turn off and on at particular times. Can't recommend highly enough.

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.

Very powerful, warms the entire home, I have made huge savings on my electricity bill, I realized gas was much cheaper. It warms better than the AC unit I had in my previous house. Easy to install.

My Avenger has been great with the temperature control and the economy mode also with the timer settings it has been a god send in the winter months.
also for circulation i can just put it on the fan without heat

The heater effectively heats large areas quickly. It reaches the desired temperature quickly. Easy to use control panel on heater. Very cost-effective and perfect for heating large areas on a family budget. The heater copes very well with high demand.

What a workhorse, I just love this heater. Yes it wasn't cheap, as gas heaters arnt, however it does a great job.
It heats our open plan house downstairs well and even the upstairs gets warmer, and it works fast. I love the kids lock on it. I like the idea of the timer settings but haven't used them. So handy to have a remote, but lost it- damn! All in all this has been a great investment that I expect to have for many years.

Purchased the heater to warm our family room instead of using the ducted reverse cycle air conditioner. Warms the room up a lot quicker and is so much cheaper to run. Highly recommend this heater if you are just wanting to heat the main room you use. It is not suitable to heat the house but then it doesn't claim to.

We have 3.1 metre ceilings and a large expanse of tiled floor, and this is all the heating we need in winter. It's a great product very reliable and quiet. Would definitely recommend. While we are yet to use the timer that option is available so you can time it to come home to a cosy room. It cuts off once reaches the desired temperature and is extremely economical to run

What great heater...Cost a bit more but well worth it ...So many people that I spoke to still have theirs going 10 to 15 years later, if you look after them ..heats up large lounge and dinning room...what I like is I can set at 19 deg and then set on economy setting....

Purchased 12 months ago. Heats up well and throughout the 76 sq m apartment. It heats up to your desired temperature with the fan then the fan turns off when temperature has reached. The timers are great to start up before you get out of bed. Completely satisfied with this purchase and would recommend . Don't forget to clean filters regularly.

We have had this model in our lounge/family room for several years and it just keeps on working perfectly!
Every winter we just turn it on and enjoy quiet heating with accurate heat sensing.
Safe for families with young ones.
Easy to clean the smooth surface. I just vacuum clean the back filters once or twice a year.

I just moved into a house with a gas Bayonet and the house is quite cold so we decided to invest in a gas heater. We were told by our plumber to get the Rinnai Avenger since it's one of the most powerful and lasts for a long time. So proud we listened to him and made the investment. The heater heats the room up in just a couple of minutes, perfect for our newborn as well. It's also easy to use and safe, switches off if it falls over. We've never heard any issues with getting burnt from touching something hot on the heater. It's also very light ...
