Benefits of Using a Dehumidifier with Built-In Pump
You have many choices when it comes to dehumidifiers—portable, whole-home, in-duct, and more. You also have a choice in how the collected water is removed. Some choose a gravity drain system, while others prefer the benefits of dehumidifiers with built-in pumps. Why?
- Pump models can move water uphill, ideal for basement installs.
- Low maintenance. With a pump, you don’t have to continuously empty water trays.
- Easy positioning. You can place the pump virtually anywhere since the pump will do all the work.
- Drain locations. With a pump model, you don’t have to worry about where the drain is located (or if you even have one).
- Automatic restart. Many models will feature an automatic rest switch in the event of a power outage.
- Greater reach. Unlike gravity drain systems or portable units, dehumidifiers with a pump can move the water as much as 50 feet or more.
Buyer’s Guide: Choosing Dehumidifiers with Pumps
There are a few different types of dehumidifiers, from compressor models that work like a reverse air conditioner system to those that use desiccant material to absorb the water. We have more details on the various types below the reviews.
However, it is important to understand the different models and their abilities or shortcomings before you buy.
Dehumidifiers work off of a humidistat. Like a thermostat, this device measures the humidity levels and will turn on or off based on your settings. The ambient temperature, region-specific locations, and other data are all needed to maintain the proper humidity level in your home.
When buying a dehumidifier, make sure the operational temperature range falls within your location’s average temperature cycles.
Capacity & Coverage Area
Like air conditioners and humidifiers, dehumidifiers work best when they are sized appropriately for the rooms or homes they work in. The capacity of the machine will determine how much moisture it can remove from the air (measured in pints per day, or PPD).
This number relies on factors like temperature, average annual humidity levels, and the size of the space. Buying a machine too large will hurt your energy bill while buying one too small will make the unit work harder and burn out motors and pumps faster.
Not all dehumidifiers are built the same. Some have noise-dampening; others do not. Usually, this is a budget or price factor. However, depending on where you plan to use the machine, it can make all the difference.
For example, base installs can handle a louder machine, which may save you a little bit of money. Installing a dehumidifier in the living room, though, will require a quieter operating machine.
Filter Indicator Light
Filters need to be cleaned or replaced (depending on the type), and trying to remember the life cycle can be difficult. If filters last 3 to 6 months, you may end up forgetting all about it until it is too late. A filter indicator light will help remind you when the filter is dirty or time for the scheduled replacement.
The drain height refers to how high and far away the drain can be from the machine. With models that have a built-in pump, you don’t need to worry so much about this. However, 10 to 15 feet drain height is about average.
With this distance, you can pump water up and out based on the pump’s abilities. If the drain area is level with the pump, it may be able to push slightly further.
Low Temperature Settings
Winter doesn’t stop the need for dehumidifiers. However, low temperatures can cause problems with the functionality of the machines. Buying a unit with low temp settings will help maintain the device’s functionality, even when temperatures drop into or below the 30s (Fahrenheit).
Frost sensors allow the machine to run in low temperatures. When the coils freeze over or develop frost, a frost sensor will tell the unit to enter defrost mode. Many will continue to operate while defrosting, though at a lower capacity. Some models will need to defrost entirely before resuming work.
Digital controls allow you the chance to have more say over how the machine operates. With LCD or LED screens and digital or touch-sensitive control options, the cost may be slightly higher, but you will know the exact settings without guessing. With dial or analog controls, you may not be exactly on the numbers you want or need.
Price & Warranty
The price is going to be the most significant decision factor out there. You want to stay within budget, but you also need to make sure the core components meet your needs. The additional features are a bonus and will help with operation and maintenance, but many aren’t needed.
Make sure when making your purchase, you get what you need in terms of size and capacity, but leave room for added features to make the investment more enjoyable.
Don’t forget to check the warranty before you buy, too. Warranty coverage will vary from brand to brand and even model to model. Time of coverage is important, but you should also know what is covered and what is not.
Many warranties require you to maintain receipts, packaging, register within a specific time frame, or even pay for shipping during a claim. Understanding these factors will help determine if the warranty, and thus the machine, are worth it. If not, you should look for a different dehumidifier.

3 Types of Dehumidifiers Explained
When it comes to how dehumidifiers do their thing, there are three basic types. Below we cover how these types work and explain why you may want to choose (or avoid) a certain type.
Compressor models are the most common. They use electricity to power a compressor that passes refrigerant through coils. This works much like your refrigerator or air conditioner. The colder, humid air is drawn in by a fan and passed over the coils.
The moisture condensates on the coils and drips into the collection tray, where it is then pumped out and drained away. The air is reheated and pushed back into the room, giving you warmer, lower humidity air in the space.
These types are much louder than the other types, and many will employ muffling options such as motor mounts or dampening shields to block some of the noise, but not always.
Desiccant models use a fan to pull air in and pass it over or through a silica gel material. Think about those little “do not eat” packets you find in items you buy. This natural moisture absorbent is used in the form of a filter material.
Electric pads are used to dry the desiccant so it can absorb more moisture. Eventually, the desiccant filters will need to be replaced but are relatively inexpensive. Because the only motor in these units is on the fan, they are extremely quiet.
However, they also lack the ability to control how much moisture is collected. Using these in larger spaces can result in too much moisture being removed from the air, leaving you too dry. They also use a lot more electricity, which can raise your monthly energy bill significantly.
Thermo-electric models use what is known as a Peltier pump. These solid-state pumps are quiet, making them ideal in dehumidifiers. However, because the heat transfer isn’t as controlled, low temps and freezing are typical.
Use of these types of dehumidifiers requires more defrosting cycles to maintain operation. The pumps move heat from one end to the other, which causes the condensation as air passes through. While they do work in smaller units, large capacity dehumidifiers tend to be more problematic.
Dehumidifier Sizing Guide: How to Choose the Right Size
To know what size dehumidifier to shop for, you first need to understand how they are sized. Sizing refers to the amount of airflow and moisture removed from that air in a 24-hour period. This removal amount is measured in pints per day (PPD).
For example, if you see a rating of 40 PPD, you know the machine will remove 40 pints of moisture for every 24 hours it runs. The rating determination was established in 2012 with different numbers. The new ratings are set to the PPD in a room at 65 degrees (F) with a relative humidity level of 60%.
Because capacity is measured in airflow and moisture, it is a simple switch to square feet of coverage. Therefore, you do not need to know how much moisture is in your air; you just need to know the square foot measurement of the room or space you want to use the machine in.
The following ranges will depend on humidity levels in your area. Higher humidity requires more PPD.
|Square Foot||PPD Capacity|
|300 sq ft||20 – 25 PPD|
|500 sq ft||30 – 40 PPD|
|800 sq ft||40 – 50 PPD|
|1200+ sq ft||50 – 60 PPD|
Average Dehumidifier Running Costs
To determine how much your dehumidifier will cost you, you need to know a few things first. The main thing you need to know is how much your electric company charges you per kilowatt-hour (kWh).
You also need to know how much wattage the dehumidifier draws. If the rating is shown in watts, you are good to go. If it shows only volts and amps, then you have a bit of math to do.
Kilowatt-hours are found by multiplying volts and amps then dividing by 1000. For example, if your machine is 6 volts and 5 amps, it draws 30 watts per hour. Divide this by 1000, or 0.03kwH per hour of use.
You can also get even more specific by knowing how many hours the unit will run per day. Assuming it is 5 hours, then you multiply your kWh by 5. IN the above example, this would then be 0.15 kWh per day.
If your electric company charges you 3 cents per hour, then the unit in the example would cost you (0.15 x 0.03) x 24, or about 11 cents per day. Over an entire year, you are looking at an average cost of $39 to run the dehumidifier.
Larger units will cost more, of course. The average costs for small, portable units (20 PPD) running 4 hours per day is about $28 per year. Large units (70 PPD+) can average about $350 per year.
People Also Ask (FAQ)
Do dehumidifiers with pumps consume more energy than no-pump models?
Yes, units with built-in pumps require more energy. On top of the energy to dehumidify the air, they also require energy to run the pump to drain the collected moisture.
Should a dehumidifier run all the time?
No. Running a dehumidifier all the time will drastically raise your energy bill and will dry your air out too much. If you don’t want to constantly turn the machine on or off, make sure you buy a dehumidifier with a humidistat control that only comes on when needed.
How do I install a dehumidifier with drain pump?
Installation isn’t much different than any other type of dehumidifier. Once you have the unit in place and set up, you only need to connect the drain hose to the machine and run it to a drain. You can also run the hose outside, into a gutter or a garden.
The only thing you must keep in mind is the distance the pump can move water. If you make the hose too long or the drain is too far way, you can end up with standing water in the hose, leading to mold or a clogged pump.
Where is the best location to put these appliances in the home or workplace?
The ideal place to put these machines is in areas where you have the highest humidity levels. This is generally the basement, crawl spaces, or wet areas like bathrooms or laundry rooms. You also want to make sure there is a drain nearby for the pump to empty the collected water into.
Where is a good place to buy these units?
You can purchase dehumidifiers with built-in pumps at most major outlets. This includes big box stores like Home Depot and Lowe’s. Walmart is also a supplier with a good selection. One of the best places, though, is through Amazon.
You will have a much higher variety of brands and models and can easily take advantage of sales, warranty extensions, or special deals not found anywhere else.
