4 Different Types of Attic Fans

Attic fans are a great way of cooling the often hot attic temperatures. Having a fan installed in the attic improves functionality. It enables you to engage in some activity or other without suffering a stifling or stuffy atmosphere. Attic fans also help to reduce the heat in the rest of the house. The extent to which they do this depends a lot on fan type. This means less energy is utilized for cooling which translates to reduced energy costs. Below are 4 types of fans that may be installed in the attic.

Type 1 - Traditional Store Type Fan

These have long been used to achieve a cooling effect when desirable. Although they move a lot of air, they leave a hole in the ceiling that is not insulated. This reduces the impact of air conditioning during the summer. In the winter, it invites infiltration of cold air into the house. These fans generate a high volume of noise. They also call for frequent maintenance when used frequently. The belt that drives the fan wears out quickly.

Type 2 - Solar Attic Fan

By using the powering effects of the sun, you are spared from using gas or electricity to operate the fan. This will reduce on your energy consumption hence reduce your energy costs. When there is plenty of sunlight, the fan’s efficiency will be at optimal level. With reduced sunlight, the fan efficiency declines. The fan will not work when the skies are very cloudy or overcast.

Unfortunately, the attic may not have cooled sufficiently when the fan stops operating. However, the fan can still work as a common air ventilator during periods of reduced sunshine. This is beneficial for the good health of household occupants. Solar attic fans are perhaps most utilized during the summer. They do not cost as much as electrical fans due to non-utilization of electricity.

Type 3 - Electrical Attic Fans

These are powered by electricity and are capable of moving lots of air. Many powered attic fans use a thermostat that turns them off and on periodically. This handy feature enables efficient energy consumption. However, you can count on increased power costs with this fan. This is especially the case during the summer when the fan is frequently in use. Installation of electrical fans involves wiring. It is best that a qualified electrician does the wiring. This will push up your home improvement budget.

Type 4 - Wind-Powered Fan

It is yet another fan type that relies on natural energy. It is a good choice for those who prefer to go easy on electric consumption and prefer a green approach. You’d have to install turbine vents to allow the wind access. When wind speed is high, these fans will exhaust much air. However, low wind speed will reduce the operations of the fan. This will leave you in stifling heat. Since it is unlikely that wind speed would be high during the day’s heat peak, wind powered fans will probably not be the most reliable choice of attic fan.
