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?

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.

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.

With rising costs to electivity and gas - finding a cost effective heater was essential. This has been an excellent buy as it is cheap to run and heats up the entire floor of my house. Buy Rinnai - it is simply the best brand in heaters and this is the best heater I have ever bought.

Finally bought a gas heater, as the bayonet was put in when the house was built ten years ago. It is used to take the chill off in the evenings, very effectively. We turn it off ten minutes before retiring to bed, and the fan goes off fairly soon, before we go upstairs.

Pumps out excellent heat and is so easy to use. Ultra quiet. Even though it is the un flued model it does not make the house smell at all. Warms the entire house and the economy function is awesome. Small condensation on some windows but I think you would get that from any gas heater.

Very happy. It easily heats 161sq . Live in a coastal area but we have it set on 22 but often have to turn it down. We utilise the economy mode and timer operations. So nice to wake up to a warm house. Would recommend it to anyone wanting quality heating.

I have had this gas heater for 5 years now and haven't had a single problem with it. I have a one bedroom split level apartment of 90 square meters and it heats the entire apartment up well. During winter I would have the heater on most days for about 7 to 8 hours. The cost to the gas bill increases about $150 over winter (4 months). Its not too big so isn't a eye sore. It doesn't give off a gas smell like some other heaters. I extremely happy with the Rinnai 25 and not disappointed I spent a bit more money for a better heater.

I'm very happy with my Avenger 25 NG, but I can't regulate the temperature. I currently have the setpoint at 21 degrees this morning, but the heater has continued to shoot up to 25 degrees and it is unbearably warm. Is this meant to be thermostatically controlled? Any help would be appreciated.

Bought this last winter since day one it heats very fast but the smell is terrible made my baby boy sick all winter i have tight chest feeling when its on we dont use anymore, every one says its normal to smell like that I dont agree if i cant bare the smell i dont think my three years old should do, i cleaned the filters many times, another problem is it doesnt stop on set temperature we set it for 21 or so only to find out after that the room temperature us 2 or 3 degrees more than set temp, any advise before throwing this toxic box in the garbage

We bought this heater 10 days ago. It is ridiculosly easy to install, easy to operate and understand, works fast (which is a delight at 4am when feeding baby), we are heating an open space of 70sq meters and it does the job effortlessly (I was sceptical). However, we live in Quakers Hill which could make a difference to someone in Oberon for instance. It is a modern design, very pleasing on the eye, not bulky but quite compact for what it does. Light in weight and the three metre hose makes it easy to manouver around if needed. The only reason I give it a 4 star is the fact that we are still to see the gas bill and find out if it is economical enough to be a five star product.

Heating great & 2 timers is a welcomed feature. Heats a large open area and makes a huge difference. Would be 5* if it regulated the room temperature, the control panel seems to heat beyond the required temperature setting which is a little frustrating. Best we would find very happy!

This products warns up the house in no time and seems to do it with ease. We are heating around 65MSQ and it works well. We have noticed the slightest of smells but nothing that has bothered us too much.
Happy to recommend this product to people with a large area to heat.
