Attic fan efficiency.

Powered attic ventilators or attic fans just as they sound are designed explicitly for placing or installing in the attics. You must have a tight seal between your living space and your attic to get an energy efficiency boost. Many are solar powered and require no other wiring so they don t cause any additional charges on your electricity bill at all. The afg pro 3 0 is possibly the most powerful residential attic fan on the market today.

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. 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. There is one major caveat to the effectiveness of an attic fan. 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.

Gable fans fit into the gable vent and can be set to operate only within a preset temperature range. 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. Attic fans serve a different function removing the hot and moist air from the attic and leaving the space below the attic floor alone.
