What Is A Crawlspace Dehumidifier And How Does It Work?

A crawlspace dehumidifier is an appliance that is used to remove moisture from the air in your home. This type of dehumidifier is different from a standard dehumidifier because it is designed to work in smaller spaces, like crawlspaces. Crawlspace dehumidifiers are often used in homes with basements or crawlspaces that are prone to flooding.

A crawlspace dehumidifier works by drawing in air from the space and passing it through a series of filters. The filtered air is then passed over a cold coil, which condenses the moisture in the air. The condensed moisture is then collected in a tank or tray, and the dry air is circulated back into the space.

If you live in an area with high humidity, you may need a crawlspace dehumidifier to help keep your home comfortable. High humidity can cause problems such as mold and mildew growth, musty odors, and condensation on walls and floors. A crawlspace dehumidifier can help remove excess moisture from the air, making your home more comfortable and protecting your belongings from damage.

Difference Between A Crawlspace Dehumidifier And A Basement Dehumidifier

When it comes to dehumidifiers, there are two main types – crawlspace dehumidifiers and basement dehumidifiers. So, what’s the difference between the two?

Crawlspace dehumidifiers are designed for smaller spaces, such as attics and crawlspaces. They’re usually compact and can be placed on a shelf or in a corner. Basement dehumidifiers, on the other hand, are designed for larger spaces, such as basements. They’re usually larger and more powerful than crawlspace dehumidifiers.

Which type of dehumidifier is best for you will depend on the size of your space and the level of humidity. If you have a small space, such as an attic or crawlspace, a crawlspace dehumidifier will be sufficient. If you have a larger space, such as a basement, a basement dehumidifier will be a better option.

Different Types Of Crawlspace Dehumidifiers

There are three different types of crawlspace dehumidifiers, each with its own unique set of features:

Desiccant Dehumidifier

The desiccant dehumidifier is the first kind. This type of dehumidifier absorbs moisture from the air. The moisture is then collected in a reservoir and utilized to re-humidify the air as needed. Desiccant dehumidifiers remove moisture from the air very well and may be utilized in a range of applications, including crawlspaces. They are, however, more expensive than other types of dehumidifiers and need frequent maintenance.

Refrigerant Dehumidifier

The second type is the refrigerant dehumidifier. This type of dehumidifier uses a refrigerant to cool the air and remove moisture from it. The moisture is then collected in a reservoir and can be used to humidify the air again when needed. Refrigerant dehumidifiers are less expensive than desiccant dehumidifiers and require less maintenance.

Passive Dehumidifier

The third type is the passive dehumidifier. This type of dehumidifier does not use any electricity or refrigerant to remove moisture from the air. Instead, it relies on the principle of evaporation to remove moisture from the air. Passive dehumidifiers are the most affordable type of dehumidifier and require no maintenance. However, they are not as effective at removing moisture from the air and can only be used in small spaces.

Refrigerant Dehumidifier

This type of dehumidifier uses a refrigerant to remove moisture from the air. A fan pulls in humid air, and the refrigerant removes the moisture. The dry air is then blown back into the room. Refrigerant dehumidifiers are more expensive than desiccant dehumidifiers, but they are more effective at removing moisture from the air.

Heat Pump Dehumidifier

Another type of dehumidifier is the heat pump dehumidifier. It uses a compressor and evaporator like a standard air conditioner, but the difference is that the air conditioner exhausts the humid air outside, while the heat pump dehumidifier recycles the humid air through the unit to be cooled again. 

While this type of dehumidifier is more expensive to purchase, it is more energy efficient than a standard air conditioner because it does not have to generate new cool air, but simply recycles the air that is already present in the room.

Air Conditioner Dehumidifier

Another option for a dehumidifier is an air conditioner dehumidifier. This type of dehumidifier works by using the coolant in the air conditioner to remove moisture from the air. The advantage of this type of dehumidifier is that it is very energy efficient because it is already using electricity to cool the air.

Factors To Consider Before Buying A Crawlspace Dehumidifier

There are a couple of things you should consider before you buy a crawlspace dehumidifier.

Space Of The Crawlspace

The size of your crawlspace is the first thing you should consider because it will determine the size and capacity of the dehumidifier you need to buy. If your crawlspace is large, then you’ll need to get a unit with a higher capacity. On the other hand, if your space is small, then you can opt for a unit with a lower capacity.

The Humidity Levels In Your Crawlspace

Another thing you should take into account is the humidity levels in your crawlspace. If the humidity levels are high, then you’ll need to get a unit with a higher capacity. Conversely, if the humidity levels are low, then you can get a unit with a lower capacity.

Capacity Of The Crawlspace Dehumidifier

The capacity of the crawlspace dehumidifier is measured in pints per day. The higher the capacity, the more pints of water the unit can remove from the air per day. If you have a large crawlspace, then you’ll need to get a unit with a high capacity.

Drainage System

Most crawlspace dehumidifiers come with a built-in drainage system. This is a convenient feature because it allows the unit to continuously remove water from the air without having to empty the water tank.

Energy Efficiency

The energy efficiency of a crawlspace dehumidifier is measured in pints per kWh. The higher the pints per kWh, the more energy-efficient the unit is. If you want to save money on your energy bills, then you should get a unit with a high pints per kWh.

Noise Levels

The noise levels of a crawlspace dehumidifier are measured in decibels (dB). The lower the dB, the quieter the unit is. If you want a quiet unit, then you should get one with a low dB.

Safety Features

Some crawlspace dehumidifiers come with safety features such as a shut-off timer, a tip-over switch, and an automatic defrost system. These features are designed to protect you and your home from damage.

Placement Of The Unit

You should also consider where you’re going to place the crawlspace dehumidifier. If you’re going to put it in a small space, then you should get a unit that’s specifically designed for small spaces.

Defroster

A defroster is a feature that prevents the coils of the dehumidifier from freezing. This is a useful feature if you live in an area where the temperature gets very cold.

Portability

Some crawlspace dehumidifiers come with wheels and handles, which makes them easy to move around. If you want a unit that you can easily move from one place to another, then you should get one with wheels and handles.

The Cost Of The Unit

The cost of the crawlspace dehumidifier is also an important consideration. You’ll want to make sure that you get a unit that’s within your budget. There are units that range in price from around $200 to $1,000.

The Warranties

You should, as a final step but certainly not the least important one, investigate the warranties that are provided by the manufacturer. You’ll want to make sure that the product you buy comes with a solid guarantee before you buy it. Some models come with a warranty that is valid for one year, whereas others come with a warranty that is valid for two years.

Benefits Of Using A Crawlspace Dehumidifier

There are many benefits to using a crawlspace dehumidifier, including:

Reduced Humidity Levels

By reducing the humidity levels in your crawlspace, you can help to prevent the growth of mold and mildew. This can not only improve the air quality in your home, but also help to protect your belongings from damage.

Improved Air Quality

The reduced humidity levels created by a crawlspace dehumidifier can also lead to improved air quality throughout your home. This can help to reduce the chance of developing respiratory problems, such as asthma.

Elimination Of Musty Odors

Another common problem in homes with high humidity levels is musty odors. These odors can be eliminated by using a crawlspace dehumidifier, which can help to create a fresher and more pleasant environment.

Protection Of Your Home’s Structure

The high humidity levels in your crawlspace can also lead to damage to your home’s structure. This is because the moisture can cause the wood to rot and the metal to rust. By using a crawlspace dehumidifier, you can help to prevent this type of damage.
