    Destratifying Heat With Large-Diameter, Low-Speed Fans
    By NINA WOLGELENTER, Big Ass Fan Co., Lexington, Ky.
    Ceiling height, insulation values, the presence or absence of floor-to-ceiling windows—all affect the regulation of indoor temperatures. With the natural tendency of heat to rise, a heating system has to work overtime to maintain the temperature set point at the occupant/thermostat level. Blending stratified warm and cool air through the use of large-diameter, low-speed fans eliminates the draft associated with typical fan circulation to achieve a comfortably heated space. [MORE]
