The VH240 whole room heater is an effective way to reduce energy costs. By using Vornado's signature Vortex heat circulation, warm air is evenly distributed throughout the room. Unlike typical heaters whose hot coils create areas of extreme heat directly around the heater, the VH240 outputs a steady current of heat that envelops the room in comfortable warmth. This household heater is whisper-quiet, and employs advanced safety features to provide worry-free use.
