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 have air con in our house but after adding another large room onto back of house the air con was not enough so after looking around and checking out as to go another air con unit or get a gas heater for the winter we found the Rinnai on display and was so happy with the way it pushed out the heat right across the room at a comfortable level. It is compact, quiet, and has an easy to use touch pad and was a bonus not to have to install a flue and also has a long lead so we can move it around if wanted. We are very happy with our purchase and find that it is cheaper to run than an air con.

Heater is one year old and needs its fourth repair. Works for a short period after each repair before emitting a stench that makes it unusable. Suffering through our second cold snap without heat. Trying to get it replaced for the last week. It's freezing and my family is cold. When it goes on the blink it seems to use high levels of gas (which is probably what's filling the house), costing me extra on refills, not to mention the added cost of using little electric heaters to try and stay warm while waiting on repair. Wouldn't buy one again.
