Attic Fans; A Rundown

Attic Fans; A Rundown

An attic fan, otherwise known as a powered attic ventilator, is a ventilation fan that equalizes a building’s attic heat level by sending out hot air.

Even so, an attic fan uses a thermostat that automatically turns off the fan and turns it on. Although, sometimes, it uses a manual switch.

Also, it can be roof-mounted, or gable mounted. More so, an attic fan requires additional vents to draw the fresh air inside as the hot air is exhausted.

However, attic fans are usually used in the summer months when the attic temperature exceeds 120 °F (49 °C). Moreover, a fan can be installed in an attic to cool the whole house and vent hot air out through the attic.

Additionally, you can wire an attic fan in different ways. Oftentimes, the fan is wired directly into the electric circuit and it is controlled by a thermostat that ranges from 60 °F (16 °C) to 120 °F (49 °C).

More so, the fan can be plugged into an electric socket and mounted nearby. Although, an environmentally friendly method is to wire the fan to a roof-mounted solar panel in a specialized way.

However, permit me to take you through a solar attic fan’s meaning, pros, and cons.

Solar Attic Fan Explained;

Solar attic fans help send out the stale air from the attic with the help of a solar panel that harnesses energy from the sun to power the fan.

They are an energy alternative to electric attic fans. They are trendy among recent homeowners and are environmentally friendly.

More so, the best thing that you can do to keep your house cool during summer is to install a solar-powered fan in your attic.

However, we need to consider some significant pros and cons to understand the nitty-gritty of a solar attic fan with a thermostat.

Attic Fan Types;

Attic Fan Types;

Generally, the attic fans types are divided into two categories. And these are the

  • Active Ventilation, and
  • Passive ventilation

Active Ventilation

An active ventilation system provides indoor air circulation via mechanical fans. This ventilation type is prone to moisture buildup or space that collects excess heat like the attics and garages.

Even so, it heeps your home free from harmful contaminants like gases in areas where cars, chemicals, or equipment are stored.

More so, it provides consistent air circulation since it does not rely on winds for operation.

However, Solar-powered ventilation systems are helpful since it operates on the sun’s energy instead of electricity.

However, this type of attic fan has some other categories, and they include:

Powered Attic Vents

Powered attic vents are also referred to as powered attic fans. An electronic-propelled fan helps you send old air out of the attic.

Also, it helps you to keep your attic at a constant temperature that relates to the rest of your home.

However, some detractors claim that the powered attic vents use too much electricity, which led to the invention of solar-powered attic ventilation systems that provide cooling benefits without electrical interference.

Solar-Powered Attic Fans

Similarly, the solar attic fans help send out the stale air from the attic through a solar panel that uses energy from the sun to power the fan.

Even so, they give cooling advantages without additional power costs. More so, they are qualified for federal tax credits and other rebates.

Ultimately, the price of a solar-powered attic fan depends on the installation cost, size, airflow, manufacturer, warranty period, and other variables.

Roof Turbines

Also referred to as whirlybird turbines, it uses an aluminum blade inside a “Cowl” to rotate and pull hot air out of your attic into the air.

The turbine blades will need to spin at about 5 to 6 miles per hour to be effective, while most homes will need multiple roof turbines to have a noticeable effect.

Even so, roof turbines are very good for harnessing wind energy from electricity and the outside air. More so, they can be propelled naturally using wind.

Passive Ventilation

On the contrary, passive ventilation systems use natural methods like thermal buoyancy and air currents to provide air circulation. Also, it helps to relate air temperature while bringing in the fresh air and sending out the heated air.

Even so, it is cheaper than other types of ventilation and requires less maintenance. Typically, it uses air vents to control the air intake.

However, it is instrumental in homes with huge differences between indoor and outdoor temperatures.

And this is because the passive system will circulate the air out.

In this category of the types of attic fans, I will be listing out some attic fan types without explanation.

This is to remain focused on the main essence of the article and not to deviate our attention.

Below are the types of attic fans in this category:

  • Gable Vents
  • Soffit Vents
  • Box Vents
  • Off-Ridge Vents
  • Ridge Vents.
