Such a great heater, just set the temp and it does heat the house well and is quiet. Optioned with timers which i dont use. The remote makes it easy to turn on from far.

Excellent heater for heating. Can heat my whole house easy.
We purchased this one cause it had a great star rating and it didnt have any flames or glowing areas for the little ones to get intrigued by and want to touch them. And also got it at a great price

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.

Purchased the Avenger 25 Plus 15 months ago. Heats a large open plan kitchen/dining/family room area on the "gas economy mode" very comfortably and efficiently. Usually set only on 19-20-21 degs. subject to outside temperature. Very happy with performance and highly recommend.

We have quite a small house and this little unit is perfect to warm up the large open areas. We do have it going for half of the day and then on at night until we go to bed and the house stays nice and warm. The unit is quite and will be sad to see it go soon as we are getting ducted aircon. Would highly recommend though. Ppl may complain of smell but when we had ours installed the guy put an air grill close to the unit which is why we dont smell the unpleasant odours, however when the unit is off we do have to put paper over it to avoid cold air entering the house :-(

We love this heater! Our home has 3.3 metre ceilings, polished floor boards, huge glass windows and this heats it up sufficiently. The installation was simple and it is very easy to use. The only suggestion that I would make to rinnai was to make the stationary vents where the heat flows from flexible so you could change the direction of the airflow but apart from that a very good, economical investment.

This heater produces a very strong smell of combustion gases that it lets off into the house since it's unflued. In a moderately large area and even with cross ventilation as is the recommendation, I experienced a headache within quite a short time. Whilst I am a sensitive individual, I would recommend instead to look at a flued gas heater or just use electric heating especially if small children, pregnant women or elderly persons live in the house.

I spoke to Rennai about the requirements for a heater and was advised that an Avenger 25 would be the best model. I used it twice on cold nights on the weekend. Today I noticed that altering the temperature setting to 18 degs doesn't turn the heater off as the room temperature is shown at 24 degs. I called the tech support who after some bafflement told me that the Avenger 25 doesn't have a temperature control and the unit needs to be turned off and on manually to control the temperature. He said I should have bought an Avenger 25 plus! What do I do now as I'm not always in the room to turn it on and off?

Heats my large open plan living room quickly and maintains heat well. Suffered with electric heating before purchasing this unit and I'm so glad I made the change. Very easy to use and love the programmable start time. Great work Rinnai.

Best gas heater I’ve ever owned! We have a massaive open area and the heater heats it all. Just set the temp and let it do it’s thing. Easy to use and quick to start. Great for the cold mornings. Very happy with purchase and highly recommended. Eco mode is great, as heater reaches temp turns down saving gas and money.

Use mainly as a backup to our wood burning heater. Works great if you don't over demand. We close off areas not used in winter. (store rooms, guest BR, etc.) Always remember any unflued gas heater needs a bit airflow. We air our house out during the day to clear any smells and vent slightly while using. It is our backup so we are not solely dependent on it. If you are going to use gas to heat, do your homework first on flued/unflued heaters and then decide. Both work when used correctly.

We bought it yesterday and I feel like that our life has been changed!
I didn’t like to use our air conditioner to warm up the room cause makes room too dry that’s the reason why we bought Gus heater.
So it doesn’t makes room dry.
Quick start, warm quickly and keep warming!

We love it!!

Absolutely love the push button automatic start, quietness. It is so efficient that we run it on economy, and at time have to turn it off. We live in a very cold zone, s o have been totally blown away by its performance. Th company we dealt with were also super.

Just bought this from Harvey, and it is chewing through the gas....hard. We are on bottled LPG and the heater has used around half a bottle in a week. Is that normal?

Would like some advice on whether or not I should be using just gas or mixture of the gas and electric option?

I have a huge living room and this heater does a great job of filling the space with warmth. The gassy smell that has developed over the past couple of winters is starting to worry me though. Perhaps it just needs a service but I really wish I bought a flued heater now.
