Attic Fan : What is it?
Attic fans are good alternatives to electricity-consuming air conditioners (AC). There are two types of attic fans: whole house fan and an attic fan. The former cools the whole house while the latter cools only the attic. Nevertheless, attic fans offer greater efficiency in allaying heat and can help save on electricity.
Kinds of Attic Fans include the following:
Whole House Fan
A whole house fan brings cooling breeze through the windows and is ideal when temperatures outside are below 82°F. This type of attic fan only use about ¼ of the total energy normally utilized by air conditioners. However, it can be noisy. To reduce the noise, use a higher quality whole house fan (e.g. one that has more blades because fewer ones produce more noise because of the strain) and install shutters around the fan.
A word of caution: Before turning the fan on, heating and air conditioning should be shut down, windows opened, and fires in fireplaces extinguished.
Attic fans improve the efficiency of air conditioners. They can save up to 30% on cooling costs by getting rid of hot air that tends to be present in attics. Attic fans use less than 300 watts and automatically go on and off with the thermostat.
Attic fans can also keep roofs in shape by keeping their shingles cool. There are two types: roof top and gable-end. Consumers also have the choice of power source (electrical or solar-powered).
|House size. Make sure that the fan is compatible with the size of your house. An ill-fitted whole house fan may cause structural damage.|
Climate. The climate in your area dictates how much work the attic fans have to do to cool your house. Be certain that the model/s you choose can withstand your natural environment.
