This whole room heater has a  thermostatic temperature control knob. Select your  desired heat setting with a simple turn of the dial.  Vornado's signature Vortex Whole Room Heat  Circulation then distributes the warm air throughout  the room. Unlike typical heaters whose hot coils  create areas of extreme heat directly around the  heater, the VH200 outputs a steady current of heat  that envelopes the room in comfortable warmth. This  heater is whisper-quiet, and employs advanced  safety features to provide worry-free use. A tip-over  switch automatically cuts the heat and power to the  unit if tipped over. With Vornado's unique design,  the VH200 outer casing remains cool enough to  touch, even after hours of extended operation. The  VH200 is backed by a 5-year limited warranty for  season after season of worry-free warmth.
