Is it OK to vent a dryer into the attic?

In addition to being against most building codes and a potential fire hazard, venting a dryer in an attic can result in moisture problems which could lead to rot or mold in your attic. If your laundry room has access to an outside wall, cut a hole and install a standard dryer vent.

How do you vent a dryer through the attic?

Vent the dryer with 4-in. dia. metal duct, going vertically from the dryer through the second-floor ceiling. Seal the ceiling penetration so that the duct can expand in length as it heats up during use (a standard roof boot, such as you’d use to flash a vent pipe, would work).

Can a dryer be vented vertically?

DEAR BOB: A vertical dryer vent is typically a problem because it acts as a moisture condenser. The sheet metal duct is cooled by the outside air in the attic. Moisture in the duct also tends to collect lint, which forms an increasingly thick layer on the vent surface, thereby reducing the efficiency of your dryer.

Can dryer be vented through roof?

Dryer vents should always be vented through the side of the house and not vented through the roof, and ideally, the exit should be fairly close to the ground. Keeping a clean dryer vent is much easier when you can safely reach the exit. A buildup of lint can cause reduced airflow and limit the efficiency of your dryer.

How far can a dryer be vented?

The maximum developed length of a clothes dryer exhaust duct shall not exceed 35 feet from the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet for each 45-degree (0.8 rad) bend, and 5 feet for each 90-degree (1.6 rad) bend.

Is it better to vent a dryer up or down?

It’s fine for the dryer vent to rise vertically to enter the building ceiling, but within the ceiling the vent should slope downwards towards its exit point at the building exterior wall. There should be no section of dryer exhaust vent ducting that is inaccessible for inspection and cleaning.

How can I vent my dryer without outside access?

Run a vent hose from the dryer to a window or door leading to the outside. This doesn’t need to be a permanent vent line but something you run with flexible aluminum vent hosing to send the heat, lint and fumes outside just when you are running the dry cycle.

What happens if a dryer isn’t vented?

However, non-vented dryers also tend to have a significantly higher upfront cost, and though they are gentler on clothes, they tend to take longer than a vented dryer to get everything dry.

Where do you vent a dryer?

Do dryers have to vent outside?

Because they emit carbon monoxide, gas dryers absolutely must vent to the outside. Ideally, electric dryers also should vent to the outdoors.

Do indoor dryer vents meet code?

The vent should be as straight as possible, and the code sets a limit of 25 feet on its length. If you have to install bends, you should reduce this limit by 5 feet for every 90-degree bend and 2 1/2 feet for every 45-degree one.
