A. An attic fan is normally automatic. An adjustable thermostat, which is included, turns the fan on and off according to the temperature. If you have a humidistat installed, it turns the fan on and off as well according to the humidity.
How do I increase air flow in my attic?
5 TIPS FOR IMPROVING YOUR ATTIC VENTILATION
- Assess Your Needs. Before you make any changes, it’s important to determine if your attic actually needs additional ventilation, and if so, how much.
- Insert Roof Vents.
- Add Soffit Vents.
- Install Gable Vents.
- Use Fans to Improve Airflow.
Do attic fans push or pull air?
The basic principle of an attic fan is that it pushes hot air out of your attic space. An attic fan pulls air into the attic from the outdoors using the soffit vents you should already have installed in the eaves.
Why did my attic fan turn on?
If the fan turns on, this is an indication there is a problem with the fan thermostat. After determining that the circuit breaker, fuse, and thermostat are working, check the fan motor – which will be the most expensive repair of an attic fan. If there is an attic fan humming noise, this could very well be the problem.
Should an attic fan run constantly?
Should an attic fan run all the time? Running an attic fan all the time in theory is a good idea. You want your attic to be close to the outside temperature. However, if you have a powered attic fan, you may not want it to run all the time because of the electric costs.
What’s the best way to vent an attic?
For the best results, place roof ventilation near the roof’s peak and soffit vents in the eaves. Air flows in through the soffit vents and out through the roof vents. Vents come in various styles. We chose rectangular, hooded roofing vents and rectangular soffit vents because they’re easy to install.
Where should an attic fan be placed?
Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor. Once they are in place, you can then place the batts or blankets, or blow insulation, right out to the very edge of the attic floor.
What is the best setting for an attic fan?
between 100 and 110 degrees Fahrenheit
Most attic fans operate with a thermostat that automatically turns the fan on and off based on a temperature the homeowner sets. Most manufacturers and contractors recommend a temperature setting between 100 and 110 degrees Fahrenheit.
What controls an attic fan?
Attic fans may be wired in several different ways. Usually, the fan is hardwired directly into an electric circuit, and is controlled by a thermostat most commonly ranging from 60 °F (16 °C) to 120 °F (49 °C). It may also be hardwired but controlled by a switch.
Do you screw up attic ventilation?
Here is where many people screw up attic ventilation. More is not always better. The thought process goes something like this: “If I add an electric or solar attic fan, or some ridge vents, or a few wind turbines or static vents or maybe ALL OF THEM, I’ll move more air and my attic will be cooler” WRONG!!!! Dirty or clogged soffit vent
Can an attic fan be installed in the gable?
Electric fans typically mount in the home’s gables. Some homeowners choose not to install an attic fan. Instead, they rely on a ridge vent — a series of ventilation ports along the roof’s peak — or a louvered vent installed in the gable.
How does a wind turbine fan fan work?
Turbine fans have angled slits cut into a capped cylinder, which create a continuous fan blade. The wind rotates the fan blade, causing air movement in the attic as air is pulled out through the turbine and replaced with outside air.
How does an electric fan work in an attic?
Anytime the fan blade turns, it draws air through the attic space. Some electric fans run continuously, but most are controlled with a thermostat. This device senses the attic’s air temperature and only powers the fan when temperatures rise above a prescribed level.
