Types of Attic Fan

There are different types of attic fans; this is bout about by the material they are made of, working capacity, and what powers them to function.

1. non-mechanical attic fans 

This is screened and with louvered vents located up on rooftops and is efficient at keeping the airspace of the attic cooler and are made up of metallic materials. They are mostly used in homes where there are other alternatives to cooling down the attic air.

2. Whole house attic fan 

This mostly keeps dead spaces causing the room to be cooler throughout. Mainly they are used in mild environmental conditions, and they serve as an alternative to traditional air conditioners.

3. Solar attic fans 

They are less powerful than electric attic fans. This solar fan creates more cooling airflow through the attic space, and they depend on solar energy to function.

4. Electric attic fans

How Does It Works?

The attic fan works in a straightforward principle whereby it pushes the hot air out of your room, at the same time pulling air from the outdoors to the attic by use of the soffit vents that are there in your eaves. The device vents hot air through the attached dormers, so it replaces the unwanted hot air with fresh air hence cooling the attic leaving the space below cold.

House Fan vs. An Attic Fan

Everyone knows that the best solar system will provide quiet operation, simple installation, and keep the attic temperature comfortable. However, to buy the correct ventilation system, you must search deeper. One thing to consider is to confuse this type of fan, as well as its purpose.

Many owners feel confused and think that the attic fan is the same as the home fan. However, the two are very different. While the purpose of a domestic fan is to maintain the interior temperature of the house according to the heat setting, the ventilation fan is only designed for the attic, providing ventilation, extracting hot air, and preventing moisture accumulation.

Can I Turn On It With AC?

Yes, you can operate the attic fan with air conditioning, but things change to solar energy. The main reason why attic solar fans are present in your home is a large number of benefits for the environment. You may ask, “How does a small product affect the environment?” This is the correct question.

A small product will not have a noticeable impact. Still, as part of a holistic approach to a home improvement or construction project, a single product can help you significantly reduce carbon emissions. Now, you can see how small solar attic fans can affect the environment.

How Long Are the Attic Fans?

The durability will depend on the materials. Materials and labor must also be taken into account when considering options for the attic fan. You want to design and manufacture high-quality metal equipment and fans with true professionals. For fans with sealed bearings and covers welded in place, you will not only enjoy a quieter operation, but this design feature also means less wear and, therefore, longer life.

Do You Have An Attic Fan in Winter?

If you have not already installed an attic fan, it may be time to invest in a solar attic fan. The reason? During the cold winter months, heat trapped in the attic can melt snow on the roof of your home. When water flows down, it accumulates and freezes in eaves or cold gutters, blocking expensive and destructive ice. With a solar-powered attic fan, minimal sunlight is required to operate and keep the attic fresh.

Besides, the warm humidity of the shower and the kitchen tends to rise and fall in the attic. This leads to mold and fungus that can saturate its insulation and cause fungus breakdown, destruction of the roof frame, and cover. With a solar attic fan, the attic remains well ventilated and prevents it from rotting.

Can You Run It All Day?

With an electric fan in the attic, to save energy, it is usually equipped with a thermostat. The disadvantage of this is that by the time the ventilation begins, the house is already hot, so it will take a while to cool down. However, since the solar-powered attic fan does not use electricity, it can run all day, from sunrise to sunset. Therefore, air circulates continuously in your home, regardless of temperature, keeping your house cool and ventilated.

Should It Be Turned on All the Time?

You can power the attic fan all the time if you use solar energy. The solar fans are cheaper than operating an equivalent electric fan and can reduce your energy bill more than your electric counterparts. Here’s how. The attic solar and electric fans are equipped with a thermostat that turns on when the attic temperature reaches a set point. Attic solar fans stimulate at a lower temperature than most electric models.

Consequently, it will keep it cool in the summer and reduce the humidity level. Therefore, the fan runs on sunlight that reduces your energy bill and keeps your home cooler in summer, reducing your need for air conditioning. This, in turn, reduces your energy bill. The low energy bill seems to be a popular topic for solar attic fans.
