A ventless dryer is a type of electric dryer that doesn't require a vent to the outdoors. Traditional dryers use a vent to release warm air outside, but ventless dryers operate differently, relying on a heat exchanger or heat pump instead. They typically come in two types: condenser and heat pump.
Using a dryer without proper ventilation can lead to increased humidity, mold growth, and potential damage to your living space. If you frequently find yourself in need of drying clothes indoors, investing in a ventless dryer or exploring alternative drying methods may be the best long-term solution.
What is a condenser tumble dryer? If you need a tumble dryer that dries your laundry slightly quicker, consider our range of condenser models. As with heat pump tumble dryers, condenser dryers do not need an externally vented hose, meaning you will be able to install your appliance anywhere in your home.
Dryers have to vent outside, because if you fail to attach a vent, it will create extreme humidity in the living space, to the point where condensation is assured. The condensation will then cause mold and greatly accelerate rotting and rusting of wood and other building materials.
The Need for Venting
Without proper venting, this moist air can lead to several problems, including mold growth, increased humidity levels in the home, and reduced efficiency of the dryer. Types of Vents: The most common type of vent for electric dryers is an external vent that leads outdoors.
Mold Growth: Dryers release moisture during drying. Without proper ventilation, this moisture stays inside, creating a perfect place for mold and mildew. This can lead to breathing issues, allergies, and damage to your clothes and home.
Ventless dryers come with a few common disadvantages. These include a smaller load capacity, a higher initial cost, and potential humidity issues.
In situations where outdoor venting is not an available option, the vent bucket serves as an efficient indoor solution. It collects lint and moisture, ensuring they do not disperse throughout your living area. It is particularly convenient for apartments or temporary setups.
The most popular solution is to vent your dryer through a nearby window. This option can be a lifesaver for people who have no other reasonable option and still wish to enjoy the benefits of having a clothes dryer right in their home.
Your dryer vent's job is to carry hot, damp air to the outside of your home. Should you direct that humidity into your garage, you would greatly increase the odds of developing a mold problem in your home.
The lint in a ventless dryer goes into a lint trap, just like in a vented dryer. Most lint traps are located just inside the dryer door. After every load, remove the trap and scrape away the lint.
Air-vented dryers draw air from the room in which they are installed, heat it and lead it through the humid clothing in the drum to evaporate the moisture. The humid air is then expelled to the external environment. Air-vented dryers thus require an exhaust to the outside, making them less practical.
Per the requirements of the International Residential Code, Section M1502 (2009-2021 IRC), the clothes dryer exhaust duct should be a rigid or semi-rigid metal duct made of galvanized steel or galvanized aluminum with a smooth interior finish and a duct diameter of 4 inches.
When a dryer vent becomes disconnected the warm moist air terminates wherever the damage to the vent has occurred. Air from a dryer vent provides a conducive condition for mold and other fungal growth. Because attics and crawlspaces are unfinished areas of a home, they are already more susceptible to mold growth.
There are two types of ventless dryers: condensing dryers and heat pump dryers. Though these appliances function differently, they both can be installed without ventilation.
Venting a gas dryer indoors can lead to carbon monoxide poisoning. Therefore, you should only consider an indoor vent with an electric dryer. Lint trapped in the dryer vent can be a fire hazard.
Fire Hazards: Running a traditional dryer without a vent leads to dangerous lint buildup, increasing the risk of fires. Moisture Damage: Without proper ventilation, trapped humidity can encourage mold and mildew growth, affecting indoor air quality and structural integrity.
But you must bear in mind that if you are going to purchase a vented tumble dryer you need to ensure that you place the dryer near an external wall or window. This then ensures that you can have a vent fixed through the wall to allow the moisture to escape outside.
Route the dryer vent horizontally to the home's outside wall. Duct work should pitch 1/4-inch per foot to the outside. This keeps moisture out of the pipe. For basement laundry areas where your ductwork will run vertically to the outside wall, you may need to use 90-degree elbows.
Are Ventless Dryers Safe to Use? Many people are concerned that a lack of venting will lead to a buildup of heat that could pose a risk of fire. This is unfounded; a ventless dryer is perfectly safe to use; they are designed to operate safely for years.
It works just fine and never gives us any trouble. We just fill it with water and connect the dryer duct. The water in the bucket collects the lint, and we change the water from time to time.
Some dryer vent installations also have an external lint trap, which is also known as a secondary dryer lint trap or a 4″ In-Line Dryer Lint Trap.
Moisture collects in the tub and is removed from the unit through the drain pump. Process air (cool dry) exits the condenser. Process air (cool dry) enters heater and is reheated. Process air (heated) re-enters drum to absorb more moisture and dry load.
It can be installed in enclosed spaces, but the doors must be open during use.
Ideally, your dryer should have exhaust vents that lead outside to keep your laundry area clean and less humid. The most common place to vent your dryer is horizontally through the exterior wall near the dryer, which is the ideal placement.
