Wind speed increases with altitude and the top of a house is pretty close to ground level.
Roof wind turbines pros and cons.
Wind turbines aren t particularly attractive to look at however they are becoming more and more aesthetically pleasing with minimum visual impact on their surroundings.
All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows.
What are the cons of wind turbines.
Wind power can be less consistent and less predictable compared to other types of alternative energy sources.
These fans are typically installed along or close to the roof s peak which is called a ridge.
However if you re in an area without a great deal of wind a turbine may not work well.
Since turbines are attached directly to attic spaces they can siphon away that moist air effectively.
Wind turbines do emit a low frequency noise.
Must have prepper tools.
A residential rooftop offers neither.
As good as they are there some traits that may make an alternative vent more suitable so let s look at those cons next.
The benefits of using a turbine.
Residential wind turbines yields energy savings and protects homeowners from power outages.
Pros these types of vents are able to provide air intake for your roof s ventilation system.
Turbine fans use only the wind blowing outside in order to rotate.
They might not be cost competitive.
These are installed into the soffit and eave areas and provide a great opportunity for you to increase the airflow through your home.
Cons unfortunately there are two sides to every coin and turbine roof vents are no different.
Cons of wind energy wind is a fluctuating intermittent source of energy and is not suited to meet the base load energy demand unless some form of energy storage is utilized e g.
How much air must be moved.
To make wind power cost effective turbines need access to strong and sustained winds.
The initial investment for wind turbines can be higher than that required for fossil fueled generators and it may take longer before an investor can break even with one s expenses.
Even worse all the obstacles trees other buildings even the house itself cause turbulence in the wind.
Roof vents need to move hot humid air from the attic to the outdoors so that humidity doesn t build up and cause mold rot or other moisture problems that findlay roofing regularly sees when dealing with attic issues.
Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing.
