Attic Fan Vs Wind Turbine

Unlike turbines this venting style does not have any moving parts.

Attic fan vs wind turbine.

Attic must have 5 sq. A turbine has a series of vanes that spin as wind passes through them. The sun does that. A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic.

My experience with the attic fan usually 1500 cfms is that they don t stay ahead of the heat production during full sun and only help in late afternoon. Good attic ventilation is important for preventing ice dams in the winter. A solar fan doesn t rely on the wind and it actually has a more powerful motor in it so it keeps the temperature of your attic regulated regardless of wind conditions. A ridge vent runs across the top of the roof s peak.

Turbine fans have no power other than wind so when the. These can be ridge vents wind turbines or the flat vents your roofer wants to install. It is costing you to run the attic fans. Turbine type vents may be electrically powered or they may turn as the wind blows.

Use an electric motor to create a draft that pulls air out through the fan. The wind rotates the fan blade causing air movement in the attic as air is pulled out through the turbine and replaced with outside air. You would probably benefit more with the wind driven turbines than the attic fans.
