More About Attic Fans

What Is An Attic Fan? How Does It Cool A House?

Attic fans are energy-efficient ventilation devices that help in maintaining the temperature of attics by pushing out the hot air of an attic and replacing it with cold air from outside. Well, it’s evident that they can’t replace air conditioners with its cooling power, but can be an excellent investment for all the energy efficient consumers. These fans consume only a fraction of energy, and thus they are called energy efficient ventilating fans. These fans work on the principle of pushing the hot air out of the attic and drawing in the cold air from the open environment.  With this mechanism, the hot air available inside attic get replaced with cold air, and the temperature of hot attic get reduced. The blades of attic fan are designed in such a way that they effectively push out and draw in the air. The blades usually have the curvy shape on their tip. When these blades rotate with the help of motor of the attic fan, the air exchanging process takes place. There is a variety of attic fans, but all of them follow the same operating principle. Whether you opt an auto speed attic fan or any other sensor-equipped attic fan with other feature, the central operating principle remains same. It’s just that the add-on improve their efficiency and cooling rate.

Key Benefits Of Having An Attic Fan

  • It’s an energy efficient approach towards cooling a hot attic.
  • It reduces ice damming chances on the roof.
  • It reduces the humidity level of an attic and thus offer protection from mold and mildew.
  • Easy to install
  • Reduce energy cost
  • A great alternative solution to your Ac

Types Of Attic Fans

There are three types of attic fans that are used worldwide. Have a look below to get familiar with them.

#1 Electric Powered Attic Fans

Electric attic fans are most potent attic fans that operate by utilizing electrical energy. Most of the electric attic fans come equipped with thermostats that control the attic fans by automatically switching them ON and OFF by requirement. This feature makes these fans energy efficient. However, when it comes to investment, electrical attic fans are more costly than any other type of attic fans.

#2 Solar Powered Attic Fans

Solar Powered Attic Fans operate by utilizing the solar energy. These attic fans are the great approach towards minimizing the electricity consumption and electric bills.  The efficiency of solar powered attic fans depends on the sunlight and exposure condition. That’s, they are highly efficient when there is plenty of sunlight, and the efficiency declines when there is none. Even they stop operating when the skies are overcast. However, these fans are the excellent choice to cool your hot attic and cost less than electric attic fans.

#3 Wind Powered Attic Fans

It’s another powerful and environment-friendly attic fan that operates by utilizing the natural (wind) energy.  Wind-powered attic fans are best when it’s about minimizing electric consumption and electric bills. However, when its about performance and efficiency, these fans face same lack of reliability and consistency as solar powered attic fans. Their ability to exhaust air is utterly dependent on the wind speed. These attic fans will exhaust maximum air when the wind speed is high. However, their performance and effectiveness will get reduced with the low-speed wind.

Things To Look For When Buying An Attic Fan

Now if you’ve planned to buy an attic fan, have a look below to invest wisely. Consider all the below-given points before you invest, it will help you to pick the right attic fan.

1. Size Of The Attic

Your attic size plays an important role, and you should never overlook the size factor. Fact is, attic fans are not made to work efficiently in every condition, several factors affect the effectiveness and efficiency of attic fans. Size is one of those factors. Before you invest in an attic fan, make sure you’ve analyzed the respective area where you will install it. The more significant will be the area, the more powerful attic fan will be required. If you do not consider and analyze the respective area before investing, probably you will end up with an attic fan that will not be performing as per your expectations.

2. CFM Output

CFM (cubic feet per minute) defines the ability of an attic fan to move the amount of air in defined time. CFM is an essential factor that you must calculate for your space before you invest. For example, if total floor area of your home is 2000 sq feet with 8 feet high ceilings, probably you have 1600 cubic feet total volume. However, if you have 10 feet high ceilings, then the area will be 20 thousand cubic feet (or +25%). Now according to the general rule of thumb, you will need an attic fan that can move at least 2 to 3 CFM per square feet of individual space. This statement is valid for standard 8 feet ceilings. Now if you have 20,000 square feet space then multiply it by 2 to 3 CFM, and you will get the result as 40,000 to 60,000 CFM. That’s the ideal CFM requirement for your space. Similarly, you can analyze your space and calculate the required CFM power. Attic fan products usually have the CFM range mentioned in their box and detail plates. So, go through the details of particular attic fan and match the CFM power of the attic fan with CFM power required for your attic space. It will help you to get the right attic fan for your attic space.

3. Mounting Type

Considering mounting type is another significant factor while picking the right attic fan with the more natural installation process. Gable mount attic fans are known to perform great when it’s about moving much heat from your house. When it’s about roof mounting, most of the people don’t agree with cutting a hole in their roof. However, it’s effortless to install a roof mount than a gable mount. So, before you invest get familiar with these essential things. What matters the most for you, your comfortability or performance of particular attic fan?

4. Power Source  And Consumption

There are three types of attic fans that operate using electrical, wind and solar energy respectively. If you’re planning to pick an electrically powered attic fan, probably you will have to pay more. Electric fans are usually costly than a wind powered and solar powered attic fan. Also, with electric powered attic fans you may have to pay more electricity bills. If you want to reduce the electricity consumption and bills, wind-powered and solar powered attic fans are the best.  However, they both operate using natural energy ( wind energy and solar energy), and that’s why their performance and efficiency is entirely dependent on environmental factors. The efficiency of a wind-powered attic fan and solar powered attic fan depends respectively on the speed of the wind and the amount of sunlight available. Thus, before you pick any attic fan, make sure you can afford the power bills or if the fan is operating using natural energy sources then make sure wherever you’re installing the attic fan has the supportive environment.

5. Ease Of Installation

Now that’s another critical factor to be considered while buying an attic fan. If you’re not willing to pay extra and hire a profession attic fan installer, always opt the one that is easy to install following the manual guide provided with the product. Before you invest, make sure the fan you’re buying has a straightforward installing process. Check whether any additional equipment is needed to install the attic fan. Check the mount type and whether you’re comfortable with it or not. Considering all these factors will help you to pick an easy to install attic fan that doesn’t involve any complex or complicated procedure.

Are Whole House Fans The Same As Attic Fans?

Usually, peoples consider both an attic and whole house fan as same ventilating devices with similar features. However, they both are different and used for different purposes. Here we have elaborated the difference. Have a look below to know.

Attic Fans

These fans are usually installed on the roof of a building or house to push out the hot air and draw in the cold air. In other words, attic fans work as an air exchanger that replaces the hot air available inside an attic with the cold air available outside in the open environment. Efficiency and effectiveness of these fans are limited to particular attic only, that’s you can’t use them if your purpose is to maintain the temperature of entire living space. An attic fan can effectively reduce the temperature on the floor of a home by 10 degrees on hot days. Attic fans are considered as energy saving ventilation devices that boost ventilation and reduce energy costs.

Whole House Fans

Just like an attic fan, the primary function of a whole house fan is to eliminate hot air from a building or home. However, these fans work to remove hot air from the entire house instead of attic only.  These fans are inexpensive and considered as an efficient approach to cool buildings and houses. A whole house fan draws cold air through windows and force up warmer air into the attic and then push them out of the house. These fans are also energy efficient and cost saving as attic fans are. So, the key differences between both these fans are the purpose and effectiveness. Attic fans are for cooling attic space only, on the other hand, whole House fans are for cooling the entire house. Both these fans are equally effective and useful for separate purposes.
