This can mean that heating thermostats need not be set as high. Similarly, fans help to cool by increasing evaporation of moisture from the skin, a cooling process.
Ceiling fans are energy savers on cooling bills.
Consider how long the fan will be in use. Fans with longer warranties will generally be more expensive but also more durable. Better fans have at least a 5-year warranty. Select a fan with at least two speeds for better comfort control. Blade material, whether wood, plastic or metal, will not affect energy savings.
