In-Wall Dehumidifiers: What Are They and How Do They Work?

In-Wall Dehumidifiers: What Are They and How Do They Work?

 

When it comes time for a more permanent dehumidification solution in your home or building, a wall-mount dehumidifier might be the best answer. These dehumidifiers are installed in or on a wall to remove excess moisture from your space and help keep your indoor humidity at the right level.

How do wall dehumidifiers work, what are the top options, and are they right for you? Keep reading to find out.

What is a Wall-Mount Dehumidifier?

We're all familiar with freestanding dehumidifiers, which sit somewhere in your room, work to remove moisture from your air, and then empty the bucket when it's full. But what exactly is a wall-mount dehumidifier?

As their name suggests, wall-mount dehumidifiers are placed in or on your wall. In-wall dehumidifiers recess into the wall, usually between studs, and are perfect for those looking for a flush-wall installation.

On-wall dehumidifiers can be mounted directly on walls for a less invasive installation on various surfaces, including drywall, concrete, masonry, CMU block, stucco, and more.

How do Wall-Mount Dehumidifiers Work?

While individual functions can vary slightly from one manufacturer to another, in general, this is how these refrigerant (compressor) dehumidifiers work:

  • Step 1: The dehumidifier pulls air from your home or building into its coils via a fan.
  • Step 2: The coils help create condensation to remove moisture from the air. That moisture stays in a tank for later emptying or is drained directly into a hub drain or plumbing line.
  • Step 3: The dehumidifier's fan then releases the dehumidified air into your space, helping to create a more comfortable living or working environment.

Where to use a Wall Dehumidifier

Wall dehumidifiers are the perfect choice for a variety of applications, including:

  • Apartments, dorms, and other multi-family buildings
  • Existing single-family homes
  • New Construction
  • Hotels
  • Schools
  • Mixed-use facilities
  • Businesses and office space

In-Wall vs. On-Wall Dehumidifiers: How to Choose

How do you choose between on-wall and in-wall dehumidifiers? It depends on your individual needs and space.

In-Wall Dehumidifiers

Since in-wall dehumidifiers fit into a wall recess, they're typically tankless and run independently of your building's HVAC system. Installing dehumidifiers in walls is ideal for:

  • New Construction
  • Renovation
  • Existing Properties

On-Wall Dehumidifiers

Like in-wall dehumidifiers, on-wall dehumidifiers are usually tankless and run independently of your HVAC system. Their less intensive on-wall installation is perfect for creative installations like kitchen islands, cabinets, and hard surface walls where recessing into the wall is difficult.

Factors to Consider When Installing a Wall Dehumidifier

When choosing when and where to install your in-wall or on-wall dehumidifier, there are a few factors to consider:

  • Location: How big is your home or building, and can the dehumidifier handle the space? Can the dehumidifier be installed without blocking an air vent? Does your floor plan allow for optimal airflow?
  • Draining System: How will you drain your dehumidifier? Will you use gravity or a condensate pump? Is a drain location accessible using a hose?
  • Power Source: What is your preferred power source? Do you want to plug the unit in or hardwire it?
  • Material: Look at the type of material the unit will be mounted on or in. Knowing the depth of the wall will help you decide between in-wall or on-wall installation.

Installation

The dehumidifier requires an opening 14.5 inches across and 30.25 inches tall. Because you must cut through both walls on either side of the dehumidifier, the installation must be in an interior wall. It can be hardwired into existing electrical or plugged into a 120-volt outlet.
