Attic Need Supplimental Cooling Fans

They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.

Attic need supplimental cooling fans.

With a hot attic the ceiling heats the building. Whole house fans need windows and doors open and attic fans need lots of soffit vents to suck cooler outdoor air up into the hot attic. Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside. When combined however they form a perfect union.

Whole house fans combined with ceiling fans and other circulating fans provide acceptable summer comfort for many families even in hot weather. A fan cools things. Install electric ventilators and attic fans which remove hot air from an attic. Without this open space the fans will not move much air.

Whole house cooling using a whole house fan can substitute for an air conditioner most of the year in most climates. The a c usage goes down. In addition to whole house fans the ducts of your central heating and cooling system can be modified to provide whole house cooling. Attic fans and whole house fans together can help with home ventilation but they serve different purposes.

The ventilation that controls moisture from condensation and regulates the temperature in your attic relies on air circulation. I ve had better success with insulation between the rafters and the hot roof radiates more to the surroundings. Ventilation fans ventilation fans or powered attic ventilators are designed to cool the attic pushing out the hot attic air and rushing in a flow of cool outside air. Generally speaking you need a ratio of 1 300 where for every 300 square feet of ceiling space you need 1 square foot of attic ventilation.

So it s natural to think of cooling the attic. A whole house fan can be run from early evening to early morning effectively cooling the structure of your home using the cool free outside air. In a properly designed passive system air enters through the soffit. Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape.

That said air resistance and interference such as vent grates reduces the area of true ventilation. By installing ceiling fans or using floor fans you can help to better distribute the cold air that comes from your air conditioner. Make sure that your attic is well insulated. The attic cools and the attic fan goes off.
