I got one of these from Noel Leeming for $160.
It heats up my large office in just a few minutes, then I can turn it off, or have it on a very low setting.
I used an oil heater previously which takes a long time to heat up, had poor heat dissipation and must have been overall more expensive to run.
Probably these fan heaters are most economical in rooms where you can close doors and the room will retain the heat better.
It's quite noisy, so fortunate I don't need it switched on much.
Because it is noisy the cold fan mode is not so useful, because you would normally want the cold fan on continuously.
Yes, I recommend this product.
