Electronic auto climate temperature control eliminates annoying hot and cold cycles, maintaining the set temperature while using less energy. The AVH2 Advanced incorporates Vornado's signature vortex technology to fully circulate the warm air throughout the room, creating a uniform temperature throughout. User-friendly push-button controls and a timer, along with a digital screen, put all of the heater's functions at your fingertips. Tight grill spirals keep curious fingers at bay while an overheat protection feature offers peace of mind as does the 5-year warranty.
