What Are Attic Fans?

Attic fans are one certain device to regulate the heat level of a building or house by exhausting hot air, they are also known as ventilation fans.

For some kinds of attic fans, it has a manual switch to control it on and off. However, the attic fans are normally installed high on the roof or gable, thus most types now choose an automatic thermostat, it turns on and off automatically.

An attic fan can be gable mounted or roof mounted based on your different needs. Used normally in hot weather, it cools down and exchanges indoor air effectively.

With a fan installed on the attic for different purposes of cooling down the whole house, it exhausts hot air effectively and quickly, which is known to be whole house attic fans. (Here we have made best whole house attic fans reviews for you if you need.)

What Is Solar Attic Fan?

Solar attic fans, suggested by their names, powered mainly by solar power. It can be installed either on the device or installed independently.

In hot weather, the sun bakes on the roof surface and thus accumulates a large amount of heat on the roof, serving as the main power for attic fans.

Like electric attic fans, there are also two mounting types you can choose, one is for gable mounted, while the other being roof mounted.

-Roof-mounted solar attic fans

Installing solar attic fans on the roof, especially when installing near the peak, sunlight heats up the heating materials on the roof, forcing hot air out and also pulling into fresh new air.

It keeps roof space and also indoor from being too high on temperature.

Roof-mounted solar attic fans not only save many costs on installing and cooling but also extend the life of shingle roof.
