What Is A Dryer Vent

Dryers play a big role in maintaining the hygiene and punctuality of your day-to-day lives. They dry your wet clothes within an hour, so you won’t have to wait an eternity before wearing them. One of the parts of the dryer that plays the most important role in drying clothes quickly is the dryer vent. But what is a dryer vent?

Dryer vents are small metal pipes that are attached to the rear end of the dryers. These pipes are terminated outside the external walls. The dryer vents are used to collect the hot, moist air, and lint from the dryer and release it outside. This makes the home safe and comfortable, as well as energy efficient.

Let’s take a detailed look at what a dryer vent is and how it works. 

What is a dryer vent?

Dryer Vent

Dryers work by passing hot air over tumbling clothes. This hot air is dry and unsaturated and hence can absorb all the moisture from wet clothes. But where does this moist and hot air go after drying? This is where dryer vents come in. So, how does a dryer vent work?

These vents are small pipes made of metal, and you can find them attached to the back of the dryer. They are usually located on the outside of the exterior wall of a building.

But sometimes they can even be found on roofs, especially if the dryers are on the topmost floor. They collect the hot air from the dryer and release them outside. 

What is the purpose of dryer vents?

Now you know what a dryer vent is. But what is its purpose? What does a dryer vent do actually? Let’s take a look. 

1. Dries clothes quickly

Before dryers came along, people had to wait hours, or even days to properly dry their clothes before wearing them again. Now due to dryers, people can wear washed clothes within an hour of washing, and dryer vents play the most important part in it.

By taking out the moist and hot air from inside the dryer to the outside, they make space for a new gust of hot air to dry the clothes. 

If the dryer vents didn’t do that, the air inside the dryer would still be hot, but it would be moist, and hence, saturated. This would’ve made absorbing water vapor impossible, and the clothes would’ve taken much longer to dry.

2. Keeps the house safe

There are a couple of ways dryer vents keep the house safe. First, when the dryer is turned on, apart from hot, moist air, the machine also produces a lot of carbon monoxide. This is one of the most harmful gases in the world, and upon inhaling it, people can get seriously sick, or even die.

So, opening the dryer vent to the inside of the house would be disastrous. 

Also, drying clothes produces a lot of lint. This lint is highly flammable, and if dryer vents didn’t exist, they would’ve been deposited inside the dryer. And as dryers can get incredibly warm while drying clothes, the lint can easily catch fire and cause serious damage to property and life.

But dryer vents keep the house safe by depositing carbon monoxide and lint to the outside.

3. Increases comfort

No matter where you have your dryer vents, if the hot air from them didn’t get deposited to the outside of your building, it would have made the house extremely uncomfortable to live in. But dryer vents collect the hot air and release it outside, which makes the house comfortable, especially during the summer. 

4. Increases energy efficiency 

Apart from making the house comfortable, having dryer vents deposit the hot air outside has another great advantage. If the house remained warm during summer, you would have to use the HVAC units more and more, causing them to consume much more energy than before. This will make the house energy inefficient. 

By depositing the hot air outside, dryer vents minimize the need to use the HVAC system, and energy consumption. This makes the house energy efficient and also saves you from paying a lot of money on energy bills.

FAQ

1. Where are dryer vents located?

Dryer vents are usually located on the outside of a building’s exterior walls. But around 1/4th of the dryer vents are located on the roofs. 

2. What is the difference between air ducts and dryer vents?

Air ducts are installed throughout the house to suck in, filter, and warm/cool the air inside the house. On the other hand, dryer vents are installed and attached to dryer vents to take out the hot, moist air and lint from the dryers. 

3. Can I use a dryer vent for AC?

It is technically possible to use a dryer vent for the exhaust of a portable AC. But, we as professionals, suggest strongly against doing so. The reason behind this is the exhaust pipes of ACs are much smaller in diameter than dryer vents. As a result, you have to squeeze the ducts hard, which might end up damaging the pipes.
