4 Different Types of Attic Fans 4 Different Types of Attic Fans

Attic fans are a great way of cooling the attic. Having a fan installed enables you to spend time in the attic without suffering a stifling or stuffy atmosphere. Attic fans also help to reduce the heat in the rest of the house. This means less energy is used for cooling, which translates to reduced energy costs. The effectiveness of an attic fan depends a lot on its type. Below are 3 common types of attic fans.

Type 1—Solar Attic Fan

By using the sun to power your attic fan, you are spared from relying on gas or electricity to do so. This reduces your energy consumption and hence your bills. When there is plenty of sunlight, these fans will be quite efficient; when there is none, their efficiency declines. They won't work at all when the skies are overcast. Despite this, these fans can still work as a common ventilator during periods of reduced sunshine and cost less than the electric alternative.

Type 2—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 based on the temperature of the attic. This handy feature enables efficient energy consumption, however electrical fans will still cost more than any of the others to operate.

This is especially the case during the summer, when the fan is frequently in use. Also, as installation of electrical fans involves wiring, you will most likely need to hire and electrician, which will ratchet up your home-improvement budget even further.

Type 3—Wind-Powered Fan

Yet another type of fan that relies on natural energy, the wind-powered fan is a good choice for those who prefer to go easy on electric consumption. They suffer from the same lack of consistency and reliability as their solar-powered counterparts, though. When wind speed is high, these fans will exhaust much air, however low wind speed will reduce their effectiveness.
