Attic Fan Efficiency

The afg pro 3 0 is possibly the most powerful residential attic fan on the market today.

Attic fan efficiency.

Many are solar powered and require no other wiring so they don t cause any additional charges on your electricity bill at all. 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. Otherwise the air circulation created in your attic could suck a significant share of your air conditioned air up and out of your house through cracks and gaps in your ceiling. 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.

The main work of an attic fan is to regulate the heat level of the attic by removing hot air out of the attic and pushing it outside providing needed ventilation. These fans circulate the air within the attic pulling fresh. You must have a tight seal between your living space and your attic to get an energy efficiency boost. There is one major caveat to the effectiveness of an attic fan.

Attic ventilation fans also tend to be quite energy efficient in terms of their own operation. Gable fans fit into the gable vent and can be set to operate only within a preset temperature range. Running at 250 watt and moving over 2860 cfm this fan uses less power than typical attic fans that move half the amount of cfm.
