Attic Fans Impact

Add the thermal switch temperature controlled attic fans.

Attic fans impact. I had a client whose wife didn t care for the sensation caused by ceiling fans. Even though an attic exhaust fan can incrementally lower the temperature of a very hot attic using a fan does not stop the source radiant heat. Maximize motor performance by adding temperature controlled thermal switch to any attic fan model. Solar star ventilation fans safeguard your attic from winter damage by.

Fans can cause increased loss of conditioned air. Eliminating damage to insulation and framing materials produced by moisture. Cooler outdoor air enters through open windows lowering the indoor temperature. Mitigating weakened internal structures caused by mold and fungus growth.

Equalizing attic and exterior temperatures. There is one major caveat to the effectiveness of an attic fan. If the home is not properly insulated a ventilator fan can actually draw cool air out of the home resulting in an increased cooling load. The fans cool the attic equalizing the temperature between the attic and outside of the home.

Depending on the type of insulation material you re using on your attic floor mold spores could potentially destroy your valuable insulation and create a health risk. The thermal switch activates when temperatures reach approximately 85 f 29 c and deactivates when temperatures drop below 65 f 18 c. During the day any cooler air brought in by the fan will be heated up immediately by the surrounding structure. Avoiding leaks and structural decay from ice damming.

In the late evening or early morning the fan is turned on to exhaust hot air from the house. Attic ventilation fans are typically mounted to an exterior wall in the attic. However a ceiling fan in a room with attic exposure also acts to disrupt the air film reducing it s r value which brings ceiling temperature closer to room ambient. But the hot air that tends to get trapped in your attic doesn t just impact that space.

Using a thermal switch the fan will turn off when it gets cold and turn itself back on when the temperature gets hot in your attic. This prevents snow from melting on your roof and freezing when it hits the cold gutter. Most fans cannot keep up. We think of ceiling fans in terms of evaporative cooling of the skin.

This type of system blows hot air out of the attic but it can have a negative effect. A whole house fan is usually installed on the attic floor near the center of your house. You must have a tight seal between your living space and your attic to get an energy efficiency boost.
