Do All Dryers Need A Vent?

What comes to mind when you hear the word ‘dryer’? Like most people, you probably imagine an appliance in the laundry room connected to a vent hose that leads outside. But do all dryers need a vent like that? What would happen if these appliances didn’t have a vent at all?

No, not all dryers require a vent to function correctly. Vented dryers must always be used with a vent hose because it helps to remove heat, lint, and moisture and expel it outside the building. However, ventless models, like condenser and heat pump dryers, do not require a vent. They can be placed almost anywhere in the home, as long as there is plenty of ventilation around.

We’ll start this article by understanding the purpose of a dryer vent. Then, we’ll look at the options you have for ventless dryers, including their pros and cons.

To understand why some dryers need a vent and others don’t, let’s start by exploring the role that vents play in these appliances.

A dryer functions by using heat to remove moisture from the clothes tumbling inside. But all of that heat and moisture needs to go somewhere. It would be very unpleasant to release all of it back into the house, so it’s best to push all of it outside.

The most effective solution for that issue is a dryer vent that goes from the back of the machine to the outside. As a result, heat, moisture, and even lint will have a direct path to escape to the building’s exterior.

No, you cannot run a vented dryer safely without using a vent. 

Suppose you were to remove the vent hose from the back of your dryer right now and continue using the appliance like normal. If that’s the case, here are the risks that you’ll face:

• Fire: Dryers already pose a certain degree of fire risk because of the heat and the buildup of lint. That risk increases significantly if you run the dryer without its vent because the heat and lint cannot move quickly to the outside of the building.

Instead, all of that hot air and lint will be blown into your laundry room, where it will continue to accumulate.

• Mold: Not only will a dryer without a vent blow hot air into your laundry room, but it will also put out plenty of moisture as well. As a result, your laundry room will quickly become hot and humid, making it an attractive breeding ground for mold, posing severe health risks.
• Carbon Monoxide: Gas dryers have one additional byproduct: carbon monoxide, which can be deadly to humans. That gas must be vented out of the house, so using a gas dryer without a vent is extremely harmful to everyone indoors. To make things worse, carbon monoxide is odorless and colorless. So, you won’t even realise that it’s building up in your laundry room and spreading throughout your house.

There are several reasons why installing a dryer vent might not be an option. For instance, there might be a lack of space, or the person might prefer not to do any renovations to accommodate a vent.

Thankfully, there are ventless dryer options available on the market from leading brands in the business. These ventless dryers fall into two categories: condenser dryers and heat pump dryers.

Condenser Dryers

A condenser dryer is a common type of ventless dryer. As the name suggests, it relies on a condenser, so you don’t have to worry about installing a vent. 

On top of that, the appliance also provides you with plenty of flexibility. That’s because you can place the condenser dryer almost anywhere in your apartment or home. As long as it’s in a well-ventilated area where warm air can escape easily, the condenser dryer will work effectively.

How it works:

Much like conventional dryers, condenser models force hot air through a drum to remove moisture from clothes. The difference is in what happens to that hot air afterwards.

Instead of being vented out, the air is channeled to a condensing chamber where the air is cooled, and the moisture is condensed into water. 

The air is then reheated to continue the drying cycle while the water sits in the water tank until you empty it manually.

You can have the water channeled to the same drain used by your washing machine on some units. That way, you won’t have to worry about emptying the water tank.

Heat Pump Dryers

Heat pump dryers are similar to condenser dryers. However, one significant difference is that these units recycle the air in a closed-loop system.

How it works:

Heat pump dryers generate heat which is then used to remove moisture from the tumbling clothes inside. These units are notable for using less heat during the drying process, which is gentler on the clothes and uses less energy.
