Rinnai Dynamo gas heater
This heater is small in size which it was I wanted but powerful enough to heat the top Quickly. I wanted a gas heater with no obvious flame as I have young children . I also wanted a timer . This heater is very efficient.

The best heater!
My parents have the same heater which I grew up with. Since moving into my own place Ive used a recirc aircon for heat but it just isnt the same. Nothing compares to the rianni gas heater, its the best and worth the money.

Great heater
Works great really quiet and safe around kids and pets as the outside doesn't get hot I'd get the 25 if you had open plan living

Just connected.
Only had the Gas fitter fit the bayonet connection for the heater. So first day of operation. So far so good. If today is anything to judge by, I am on a winner.

Quality all the way ..
Easily heats up small to medium rooms without any problem .. in fact will even do a larger room as heat gets around pretty quick. For my smallish office space it only needs to be on L the lowest temp setting and it heats it up rather quick. The remote is extremely handy and I have never had to touch the heater at all. Cannot go wrong with Rinnai as long as you service it once every 2 years or so. Brilliant gas heater!!
