The Danger Behind the Door: Why Stacked Dryers Are at Higher Risk

Stacked washer and dryer units are fantastic space-savers, especially in apartments and townhouses. However, their placement in tight, shallow closets creates a unique and significant fire hazard.

The Crushed Hose Dilemma

Because space is limited, stacked units are often pushed as far back against the wall as possible so the closet doors can close. This frequently results in the flexible aluminum transition hose being severely crushed or kinked. A crushed hose instantly restricts up to 90% of the dryer's airflow.

Trapped Heat and Out of Sight

When airflow is restricted, the dryer overheats rapidly. To make matters worse, the space behind a stacked unit is virtually inaccessible to the homeowner. Lint begins to build up at the kinked section of the hose, creating a highly flammable blockage in a confined space. Because it is hidden behind a heavy, stacked machine, the warning signs are easily missed.

The Right Way to Vent Stacked Units

Stacked dryers should never rely on flimsy foil hoses. They require specialized rigid metal ducting or "periscope" vents that maintain a smooth, open pathway for air even when the machine is pushed against the wall.
