How big is a ventless heat-pump dryer?#
A ventless heat-pump dryer is 24 inches wide as a compact (33 to 34 inches tall) or 27 inches as a full-size (38 to 39 inches tall), with a stacked pair reaching 66 to 70 inches. The table below sizes each, and the clearances show why it fits places a vented dryer cannot.
Ventless heat-pump dryer dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |

Installation clearances for a ventless heat-pump dryer#
- Rear clearance: 2 in in behind a ventless heat-pump dryer, since it condenses moisture instead of ducting it outside.
- No vent duct: A ventless heat-pump dryer needs no exterior vent, so it can go on an interior wall a vented dryer never could.
- Condensate drain: A ventless heat-pump dryer empties its condensate into a reservoir or a drain hose, so plan for one within reach.
- Door swing: 20–24 in in of front space a ventless heat-pump dryer door needs to open in a tight closet.
Will your ventless heat-pump dryer fit? Clearances and door swing#
The whole point of a ventless heat-pump dryer is placement freedom, and the clearances reflect it. Because it condenses moisture instead of ducting it outside, it needs no exterior vent, so it can sit on an interior wall — a condo, a closet, or a middle-of-the-house laundry — where a vented dryer never could. Behind it you need only about 2 inches of rear clearance, far less than a vented dryer's duct demands. The one plumbing consideration is condensate: the dryer empties its collected water into an onboard reservoir you dump, or a drain hose you route, so plan for one within reach. In front, the door needs 20 to 24 inches to open in a tight closet. Confirm the rear 2-inch gap, the condensate path, and the door swing, and it drops into spaces a standard dryer rules out.

Ventless heat-pump dryer sizes by type: compact heat-pump dryer (24-inch), full-size ventless dryer (27-inch), stacked ventless pair#
The compact heat-pump dryer at 24 inches wide and 33 to 34 inches tall is the condo-and-closet answer, fitting where there is no vent path and no room for a full-size unit. The full-size ventless dryer at 27 inches wide and 38 to 39 inches tall brings standard capacity to a laundry room with no exterior wall to duct through. The stacked ventless pair puts a ventless dryer over its matching washer at 24 inches wide and 66 to 70 inches tall, turning a closet into a full laundry by going vertical. All three skip the exterior vent and need only the 2-inch rear gap and a condensate path, so the choice is capacity and layout: compact for the tightest spots, full-size for a real laundry room, and stacked to save floor space.
