When hot air rises above 82F and you decide to use air conditioning, you can shut the windows and crank up the air knowing that the attic fan will save up to 30% on cooling costs by getting rid of trapped super hot air that tends to collect in attics and cause heat to back up into the home. Without the fan, the house gets hotter and hotter all day long and the ac never stops. When it gets to 150 degrees in your attic it begins to penetrate your living space. With the solar attic fan, the hot air is removed, allows cool air in and your A/C runs much more efficiently. Attic air is 60 degrees cooler and less heat penetrates the rooms.
JUST A LITTLE POWER TO SAVE MONEY BY REMOVING ALOT OF HEAT!
Solar Attic Fans create a positive airflow through your attic that does not rely on wind or require excessive passive venting.
Excessive passive venting can cause excessive moisture infiltration in the form of snow or rain. The attic fan is normally mounted up on the roof of the home toward the back about two feet down from the peak. It goes on and off automatically with a thermostat, so it only runs when it is beneficial.
The attic fan has a flashing that fits in with the shingles and is waterproof. Attic fans use less than 300 watts, and offer these important advantages:
1. Lowers upstairs room temperatures by 10°
2. Lengthens roof life by keeping shingles cooler
3. Saves up to 30% on air-conditioning costs
The exact savings obtained depends on several factors like: The color of your roof, if the home is shaded, the amount of insulation you have, and the efficiency of your cooling system.
Ideally, a solar attic fan installation will pay for itself within 3 years. The high quality Power-Save Solar Attic fan is recommended.
But the benefits don't stop there, in winter the solar attic fan continues to help the homeowner, as many of today's houses have insufficient ventilation and attic air exchange. This causes high humidity levels from everyday activities. This moisture migrates through the ceiling towards the roof where it comes in contact with the cold structure. Here, ice and frost form, causing damage to your roof structure. Additionally, moisture can saturate insulation, promote fungal decay and plywood delamination.
