Adding Fan To Attic Vent

I added a attic fan 1500cfm onto the gable but i have the airflow coming in from the outside instead of pushing air out.

Adding fan to attic vent.

Cool air enters the attic through soffit vents in the eaves. Adding attic vents is a simple matter of cutting holes and installing vents. I ve read that adding a vent fan to the gable with ridge vent is bad b c it may reverse the natural flow of hot air plus draw in rain. Whether you choose to employ flow through cooling with a gable vent at each end of the attic or other forms.

Blades spin within the unit to expel air from the attic until the right temperature or moisture level is reached at which point it will automatically shut off. Photos 1 6 show how it s done. A powered exhaust vent is much like a roof mounted exhaust fan. The remington solar ventilation attic fan is completely the remington solar ventilation attic fan is completely powered by free solar energy.

Step 6 remove any insulation from the new vent photo by merle henkenius. If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air. Mark the roof venting locations from the attic where you can see the rafters and avoid placing roofing vents over them. Once inside the air heats up and rises higher ultimately exiting through venting at the roof s gables through ridge vents cut into the roof s apex or other vent holes in the roof.

Attic fan ventilation attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents soffit and gable and pushing hot air to the outside. That said air resistance and interference such as vent grates reduces the area of true ventilation. In other words the entire vent opening doesn t count as vented space. It can be controlled by a thermostat or moisture monitor.

Adding proper venting to your attic can cause dramatic drops in summer cooling costs. Trim the last vent to length using aviation snips. However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the attic. One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home.

Most homes already have some passive attic venting built in. But before you cut any holes plan the locations of the attic vents. The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents.
