Rinnai RINV51RC (5.1kW)

I am an air-con installer. This was my first unit out 500 plus i installed. Ran for week and all of a sudden stopped heating . On behalf of customer i raised the warranty claim. It took week for technician to visit. Initially they took the credit card detail of the client advising in case it was installers fault ( my fault). technician went out and confirmed it was fault with outdoor unit and will be fixed in 3 weeks time. what a product quality and warranty service they offer. I can also comment about the product but i believe it is not good for my profession.
shame on Rinnai.

This unit was installed in our investment unit in July 2016. At October 2018 the unit had malfunctioned and would not work (no power indication, no cooling, heating or fan operation). By all accounts the unit heats/cools well, however, we would have expected the mean time between failure to have been longer.

We recently purchased this aircon on a 40 degree day and had it installed immediately. The plumber and electrican advised the job was “easy”. The aircon works excellent and cools down almost my entire 4 bedroom 2 lounge house. (Single story). The numbers on the screen are dull which means at night we are not kept awake by a bright light.

Ok system. Value for money, however as compared to other systems out there it has lots of rooms for improvements. I really love the LED temperature interface as I do not have to look at the remote to find out what the temperature is.

The system cools pretty fast for my living room which is pretty good however after reading the first comment, I don't know how long this system will last.
