Do Attic Wind Turbines Work

A ridge vent runs across the top of the roof s peak.

Do attic wind turbines work. No additional source of power is needed and turbines are available in a wide variety of sizes and styles. Laughing okay well that s what i was wondering about. Wind turns the propeller like blades of a turbine around a rotor which spins a generator which creates electricity. You nailed it by talking about average wind speed.

A drafty house is not but a drafty attic is good. Naturally the action of wind turbines depends on the wind. As the wind moves across your rooftop it turns these turbines and draws air up out of your attic area. Unlike turbines this venting style does not have any moving parts.

A turbine has a series of vanes that spin as wind passes through them. It also keeps your home cooler in the summer vent moisture that finds its way from the living spaces of your home into the attic and helps shingles last longer. Wind turbines work on a simple principle. If the wind is blowing and catches the fins then the turbines act like giant vacuum pumps sucking hundreds of cubic feet of hot air out of an attic per minute.

Instead of using electricity to make wind like a fan wind turbines use wind to make electricity. Depending upon the diameter of the vents and the wind speed outdoors the turbines can expel vast quantities of humid air before it becomes a problem. 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. Well now you know.

Typically a rooftop will use two or three of these turbines depending on the size of the roof. The faster the wind speed the faster the turbine rotates. And in fact just so you know those spinning roof vents are probably not the best way to vent your roof. These can be ridge vents wind turbines or the flat vents your roofer wants to install.

They come in different colors. Turbine fans have no power other than wind so when the. A small 12 inch diameter turbine vent with a constant wind speed of 5 miles per hour mph can remove 347 cubic feet of air per minute cfm from the attic space. Good attic ventilation is important for preventing ice dams in the winter.

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.
