I live in an older apartment building in north Chicago. It can get COLD. My 6 month old son will not go to sleep in a room that's not warm & toasty. The Vornado did the trick. My wife or I turn it on about an hour before his bedtime and when its time from for bed, the room temperature is to his liking. Once he's asleep, we shut it off the Vornado and he stays asleep.
I wouldn't recommend this heater for larger rooms - it did nothing to warm-up our living room the time I tried it - but for the need I had it worked great.
The Vornado Heater looks like it would be very good to place in a bathroom
or under a desk.
