Ceiling fans can save energy and money for heating and cooling. A quick rule of thumb for sizing them matches the diameter of the fan with the largest dimension of a room. For 12 ft. or less, use a 36-in. fan. For 12 to 16 ft., use a 48-in. fan. For 16 to 18 ft., use a 52-in. fan. And for dimensions larger than 18 ft., install two fans. Placement of a ceiling fan for adequate air circulation is 7 ft. above the floor with the blades 8 to 10 in. from the ceiling. And to move more air at low speed, a fan with five blades is best. Regarding energy savings, research has proven that ceiling fans can save energy during the cooling season by creating a gentle breeze. You get your savings then by raising your thermostat by a minimum of 2 degrees. This decreases air conditioning energy used by 10 to 15 percent, or 5 to 8 percent per degree. By reversing your fan (so it runs clockwise) during winter, you pull heat from the ceiling and push it down to the floor for more even heat.ncG1vNJzZmivp6x7p63MoqOyoJGjsbq5wKdlnKedZLmqv9NoaGlpXam1qrrGrGShp52avLi6xKuqZqWlqMFut82ormg%3D
