Do Attic Wind Turbines Work

Good attic ventilation is important for preventing ice dams in the winter.

Do attic wind turbines work.

Wind turns the propeller like blades of a turbine around a rotor which spins a generator which creates electricity. The payoff works when you install the turbines where wind blows most frequently 2 4 times the average of the area isn t unusual and the power output increase isn t linear so if you live in an area with double the wind you ll pay it off in 1 4 of the time making it very worthwhile. Instead of using electricity to make wind like a fan wind turbines use wind to make electricity. Wind turbines work on a simple principle.

A ridge vent runs across the top of the roof s peak. No additional source of power is needed and turbines are available in a wide variety of sizes and styles. Typically a rooftop will use two or three of these turbines depending on the size of the roof. Laughing okay well that s what i was wondering about.

As the wind moves across your rooftop it turns these turbines and draws air up out of your attic area. You nailed it by talking about average wind speed. And in fact just so you know those spinning roof vents are probably not the best way to vent your roof. Turbine fans have no power other than wind so when the.

A turbine has a series of vanes that spin as wind passes through them. This is a standard turbine vent. Naturally the action of wind turbines depends on the wind. 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.

Well now you know. 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. 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. A drafty house is not but a drafty attic is good.

They come in different colors. 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. These can be ridge vents wind turbines or the flat vents your roofer wants to install. Somebody told me well you ll save money in the winter if you cover your turbines up tom.

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