Attic Fan Temperature

Attic ventilators generally turn on between 90 and 110 degrees fahrenheit.

Window fan small. The whole house fan is installed inside the attic between the living space and ceiling. In such doing the attic fan will reduce the temperature in the attic space that in turn cools down the whole house. Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside.

Ideal attic temperatures shouldnt be more than 10 to 20 degrees hotter than outside temperatures. Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets. The fans cool the attic equalizing the temperature between the attic and outside of the home.

Such fans are often called whole house fans. If your attic soars above 100 degrees and reaches the 150 mark its time to consult. Of course some environments are much hotter than others so this will be the perfect time to measure out how warm your attic will get during the most heated of seasons.

As the attic cools the smart fan will automatically cycle down to lower speeds the lowest being 1000 cfm which only uses 15 watts of energy resulting in a cheaper air conditioning bill and cooler home temperature temperatures can drop as much as 50 degrees these two factors make it an excellent energy and cost saver. In particularly hot climates set the temperature higher to keep the fan from running for extended periods of.

An attic fan works by drawing in cool air to the attic space that pushes out the hot air through vents. This prevents snow from melting on your roof and freezing when it hits the cold gutter. This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner.

The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. Mechanical attic ventilation fans may be powered in a variety of.
