Advice needed: Choosing most efficient ceiling fan
We need a ceiling fan w/60" blades for our family room and have narrowed our choice down to two. We don't know how to determine which will be more efficient, electricity-wise:
Fan "A":Airflow: 6967 CFM, elec use: 88 watts, Airflow efficiency: 80 CFM/watt
Fan "V":Airflow: 4646 CFM, elec use: 12 watts, Airflow efficiency: 384 CFM/watt
Please give me your advice. Thanks.
