Enjoying our new Rinnai Inverter Split System Air Conditioner HSNRQ50B 5.0KW

Last split system we had was a Daikin but this was more affordable and modern. The size of the system was as required by the size of room, which is a loungeroom. We run it quite warm – at 26.0 degrees as I don’t like to feel chilly although hubbie likes it arctic! He accepts that 26 degrees will keep the room nice and cool even in those 47 degree days in January, we lived in the lounge-room as it’s the only air-conditioned room. The Rinnai is quiet, one click on and off and I was super surprised to see our electricity bill for the summer 3 mo…

Great value and works well HSNRQ80B 8.0KW

Perfect for small room HSNRQ25B 2.5KW

Purchased in November from Harvey Norman for bedroom use. 2.5KW easily cooled down room on over 40+° days over summer. Great energy rating. We generally set at 22° on medium fan and it’s perfect. Didn’t make a huge impact on our energy bills. Quick to turn on and cool. Easy remote functions with very easy timer!!!
Just started using heat setting to warm room up. Warms up in ok time. We just close door on colder nights. Timer function great to set so not on all night.
Very quiet. Temperature lights up on unit.
Installed through Harvey Norman during installation special. Small unit outside.
Great brand. Would purchase a Rinnai again.
