INDUSTRIAL FAN WARNING!: This fan is rated as an industrial ceiling fan and therefore must be installed with the bottom of the blades at least 10 feet from the floor. That typically means that the ceiling must be at least 12 feet high in order to install an industrial ceiling fan. This is because the blades are very thin and spin at a higher RPM than typical ceiling fans, which makes it dangerous when hung at the same height as a typical fan. Call for details.

How does the Emerson Heat Fan 48 Compare to the Average Ceiling Fan?
Ceiling Fan Comparison Graph
Breeze Rating: 5.5 (5 is best)
Wind Speed Factor: 4.57 MPH
Graph represents 48" blade span
How to read our graphs
Quality Rating = 5 (average is 3)
With a Quality Rating of 5, the Emerson Heat Fan 48 is among the finest quality ceiling fans made. It will run smooth and quiet without wobbling or making noise and you can let it run
24 hours a day for years on end without any worries of the motor burning out.
Wind Speed Factor: 4.57 MPH (average is about 3)
Airflow = 6879 CFM
A Wind Speed Factor of 4.57 MPH gives this fan a Breeze Rating of 5.5 out of 5.
This is over the top when it comes to wind speed, so this fan provides about the strongest breeze you can get from a ceiling fan, making it one of the best fans you can buy to cool you off!
Aside from Quality, which accounts for smooth quiet operation and durability, the amount of wind-chill a fan can provide to cool you off is the most important consideration.
Afterall, why do want a ceiling fan in the first place?
(average is about 5,000)
6879 CFM is a good amount of aiflow and is above average. We highly recommend ceiling fans that move at least this amount of air in order to provide enough wind chill effect to keep you cool.
The Emerson Heat Fan 48 will allow you to raise your thermostat by several degrees, which will help you save additional money on your cooling bills (if you have AC).
Efficiency Rating = 96 CFM/Watt (average is about 86)
An Efficiency Rating of 96 is
Efficiency is defined by the EPA as the amount of airflow a fan produces (CFM) divided by the amount of
electricity (Watts) it uses on high speed without any lights on. Efficiency is less important than Airflow because more
CFMs allow you to raise your thermostat higher...which is where you will save the most energy. Efficiency becomes more important if
you expect to operate several ceiling fans at the same time. (see calculator below)
Electrical Usage = 72 Watts (average is about 76)
72 Watts per hour is
pretty close to average, so it will cost about the same to operate the Emerson Heat Fan 48 as most other ceiling fans.
Use the calculator below to estimate just how much it will cost to operate this fan in "Your home".
Wind Speed Factor -vs- Efficiency: Wind Speed is KING! Ceiling fans can save you a lot on your energy bills if you use them properly to reduce your use of central air.
Ceiling fans cool you off by creating a wind-chill effect, so the more wind speed a fan generates, the cooler it will make you feel. The cooler your ceiling fan can make you feel, the higher you can raise your AC thermostat to conserve energy without sacrificing your level of comfort. Raising your thermostat by 10 degrees can save you up to 40% on your cooling bills, but you cannot raise your thermostat by 10 degrees if you focus only on ceiling fans that use less energy rather than ones that generate higher wind speed. To put this in perspective: A typical central air system uses about 3500 Watts when it is running, so if a ceiling fan that uses 100 watts allows you to raise your thermostat a couple degrees higher than a more "efficient" fan that uses only 50 watts, the savings you will get by raising your AC therestat a couple degrees higher is far more than the difference of 50 watts between the two fans. With that said, a ceiling fan that uses less watts yet produces higher wind speed is a win-win.

Fan Size -vs- Wind Speed -vs- CFM
Note: The formula for calculating wind speed was revised on 1/31/2015. The previous formula did not take into account that the testing chamber (cylinder) used to determine the CFM of a fan is 8" in diameter larger than the blade span. The revised formula ads 8" to the fan diameter to account for this. The wind speed results are now slightly lower than previosly stated
"When it comes to ceiling fan size...the largest fan with the highest wind speed that will look fine in the area is the best choice!"
Ceiling fans cool you off by creating a wind-chill effect, the degree of which is determined by the wind speed produced by the fan; the higher the wind speed, the cooler you feel. It is critical to know the following; CFM is not the same as wind speed; the wind chill effect you feel from a ceiling fan is concentrated in the column of air directly beneath the fan blades; the wind chill drops off dramatically just a foot or two outside that area.
Ceiling fan manufacturers are required by the DOE to publish the airflow of each fan in CFM (Cubic Feet per Minute) which is not the same as wind speed. CFM is the volume of air being moved every minute, whereas wind speed how fast the air is moving in MPH (Miles per Hour) or LFM (Linear Feet per Minute), both of which are directly related to the amount of wind chill effect. When you compare two fans that are different sizes yet have the same CFM you will find they produce quite different wind speeds. The smaller fan must move air faster in order to move the same amount of air per minute (CFM) as the larger fan. The airflow generated by the smaller creates more wind chill because it is more concentrated and has a higher wind speed. The larger fan of equal CFM moves air over a larger area so it is less concentrated at a lower wind speed. So when determining what size fan to buy you must consider the amount of space a fan will cover (the diameter of the fan plus a foot or two), the intensity of the airflow directly beneath the fan (the wind speed) balanced with how any particular size fan will look or fit in the space. Ultimately the largest fan with the highest wind speed that will look fine in the area is the best choice for performance.
The required testing method for ceiling fans is not done in a way that translates well to real world applications, so the CFM data can be somewhat deceiving if you do not know how to interpret it.
The current required test procedure (shown left) shows a ceiling fan hanging above a 3 foot tall metal cylinder that is 8 inches wider than the ceiling fan (blade span) and stands 4 feet above the floor. Sensors are located at the bottom of the cylinder to measure the wind speed. The wind speed is then converted into CFM (Cubic Feet per Minute). Although this testing procedure can be valuable for comparing the performance of fans equal in size, it does not emulate a real application inside a home and does not make it easy to compare fans that are different sizes in order to determine the best size fan(s) for any particular application.
Therefore, the best way to compare the actual performance between fans of various sizes is to compare the wind speed. The wind speed of a ceiling fan can be mathematically calculated based on the CFM and Blade Span. Here is a comparison where we performed the calculations between 3 fans of different blade spans and CFMs. The largest fan has the highest CFM yet the smallest fan produces the highest wind speed.
84" Fan with CFM of 10000 produces wind speed of 2.46 MPH (216.62 LFM)
52" Fan with CFM of 6500 produces wind speed of 3.76 MPH (331.04 LFM )
The above example shows how deceiving CFM data can be. Even though the 52" fan moves 35% less air than the 84" fan, the intensity of the breeze that produces a wind-chill effect is over 50% more than that of the larger fan and will make you feel much cooler if you are directly beneath it. So, to cover a larger area, two or more smaller fans with good performance may be a better choice than a single large higher CFM fan.
