The Vornado SRTH effectively circulates heat, without the need for oscillation, using V-Flow™ heat circulation. By passing the heat through specially contoured louvers, the SRTH distributes the heated air in a wide, V-shaped pattern that creates a more consistently comfortable space. This wide, powerful airflow is superior to oscillating heaters that create unbalanced heat output and leave hot and cold spots in the room. The SRTH gives you simple control providing 2 heat settings, 4-hour auto shut-off timer and a continuous fan-only setting for year-round use. The SRTH is equipped with a host of safety features, including a tip over switch, automatic safety shut off if airflow becomes obstructed, a sturdy, non-oscillating base, and an exterior that stays cool to the touch, even after hours of operation. A More Effective Way to Heat The Vornado Small Room Tower Heater effectively circulates heat with V-Flow Heat Circulation with up to 90 sq. ft. heating capacity. Uniquely contoured air outlets create a wide span of constant heat. With V-Flow Heat Circulation, a current of heat is continuously moving throughout the room, creating quiet, comfortable whole room heat circulation. 3 settings Include a 450W low-heat setting and a 900W high-heat setting for flexible heating options, plus a fan-only mode that offers cooling airflow. Cool-touch case Makes the unit safe to touch, even on high-heat settings. The tight grill spacing helps resist curious fingers. Whole Room Heat Circulation Ordinary tower heaters skimp on circulation, which creates hot spots near the heater and cold spots everywhere else. The Vornado Small Room Tower Heater with V-Flow heat circulation distributes the heat more effectively than oscillation can, providing whole room comfort. Optimum Performance Position your heater so the V-Flow distribution of warm air is directed across the room, unobstructed, and in a location that is representative of the room temperature. Avoid areas of temperature extremes such as cold drafts and heat registers. When placing near a wall or corner, allow at least 6 inches of space to ensure the heater has adequate room to intake air, providing optimum performance.
