Review & Description
Quite simply the best product you can buy to reduce heat build-up in your attic in the summer and remove harmful moisture in the winter. The solar panel and fan motor have up to 25% more power than other fans, providing much better circulation and improved airflow. The advanced design provides more efficient attic ventilation while using no electricity.One fan alone can ventilate up to 1150 square feet of attic space reducing the energy needed to keep your home cooler in the summer. By running year-round, it can also remove harmful moisture in the winter months keeping your attic space drier, reducing condensation, and the potential for ice daming, mildew and mold. Cools in the summer - During the peak summer months, your attic's temperature can rise to 160° or more. This heat build-up can raise the temperature inside your home and increase the amount of electricity used by air conditioners and other cooling equipment. Removes damaging moisture in the winter - During the winter months, warm moist air from inside your home rises into the attic and collides with the colder underside of the roof. The moist air condenses and promotes mold and mildew. If you live in an area that has snow, the warmer attic air will heat the roof and melt the snow which drips to the eaves where it can refreeze as ice and form ice-dams under the eaves. These ice-dams will cause water to work back up under the shingles into the attic and down to the ceiling. Intelligently simple attic ventilation - With the addition of the optional Solar Controller with Dual Mode Technology your Solar Powered Attic Fan will now have the ability to run after sunset, or when there is inadequate light available from the sun. When there is no sunlight available to power the fan and the Solar Controller has the optional house power connection enabled, the Solar Controller will cycle house electricity for 8 minutes every half-hour in order to power the fan.
