What are the advantages of dehumidifiers with pumps?
The main advantage of using a dehumidifier with a pump is that the moisture collected in the unit can be pumped upward from the floor into a bucket, sink or out a window. When operating in continuous drain mode, these dehumidifiers do not require much attention, and as no water is collected in a reservoir, they practically don’t smell of bacteria, mold or mildew.
However, these devices are usually on a pricey side. If the area you want to dehumidify is less than 500 square feet, consider getting a smaller device with a continuous drain option. This way the water tank will be emptied through a hose with the help of gravity which though might be inconvenient for some will save you tons of money. Of course, if the area you need to dehumidify doesn’t have a drain hole in the floor, a dehumidifier with pump is the perfect way to go.
Features to consider while choosing a dehumidifier
Basically, the more pints of water a dehumidifier can collect in a 24-hour period, the better it is going to perform, with the price generally escalating for models, such as the AlorAir HDi90 Basement/Crawl Space Dehumidifier that can collect as many as 90 pints per day.
Drain height refers to where you intend to position the hose attached to your dehumidifier with a pump. For instance, if you want to discard the water outside a window that is positioned eight feet high above where you plan to place the unit, then you want to look at models that can pump moisture at least eight feet high. The Tosot 70 Pint Dehumidifier with Internal Pump, can pump water as high as 15 feet which is more than needed in most situations. Some units, such as the De’Longhi 70-pint Dehumidifier with Patented Pump also come with a three-foot hose that allows the machine to be drained a short distance away from an open basement drain.
Water tank capacity
Water tank capacity only really matters if you know that you won’t be using the continuous drainage option all the time. Otherwise, the entire purpose of a dehumidifier with a pump is to have it running continuously and draining directly from a hose or tube out the window or into a sink or floor drain.
If you plan on using the dehumidifier without the hose then the bigger the tank capacity, the longer it will run without you having to empty it.
The coverage area of these five best rated dehumidifiers with pumps is quite vast, from 1,000 to 4,500 (as seen in the Ivation 70 Pint Energy Star Dehumidifier with Pump) square feet. Before buying one, consider the size of the space that you want to keep dry.
Generally, the larger the coverage area to be dehumidified is, the more necessary it will be to run the compressor pump continually and lead a hose to a drain to avoid having to empty the reservoir tank repeatedly.
Dimensions and weight
The size of the dehumidifier with a pump that you purchase will matter a lot depending on whether or not you will be moving the unit from room to room. If you intend to relocate it frequently or need to wheel it next to a drain to empty it manually, then choose a model that has casters.
Some models also have handles and weigh less than others, so they can be carried from place to place. However, for the most part, it is best to find a permanent spot with a drain nearby.
Look for units that offer phased warranties to cover the different components of a dehumidifier with a pump. Most will provide a year-limited warranty on parts and labor, a three-year limited on refrigeration system and a five-year limited on the compressor. The best rated dehumidifier with a pump should also have a 30-day return policy.
Extra features to look for in a high-quality dehumidifier with a pump are a backlit LED display, room humidity, and temperature monitoring and a timer to program an auto-shut off. Quality dehumidifiers with pumps will also shut off automatically if malfunctioning and turn themselves automatically back on again if there is a power outage.
In general, dehumidifiers with pumps are noisier than no-pump ones because of the sound of working internal compressors and fans. However, the noise level doesn’t usually surpass a 50-60-decibel level, which is comparable to a normal conversation.
Regarding overheating, the real concern is the condition of the dehumidifier coils. In case they freeze, the unit won’t work as effectively and will more likely overheat. That’s why always check the product specifications to know what’s the minimum temperature the model can work in and if there’s an internal defrost system. Also, place the unit at least six inches away from the walls and other objects to avoid inflammation.
It is best to keep the relative humidity (RH) level in your home between 30 and 60 percent, with the ideal RH between 40 and 50 percent. It’s also important to remember that if the dehumidifier setting is above 75 percent, it can provoke the growth of mold and mildew.
The eco-efficient Ivation 70 Pint Energy Star Dehumidifier with Pump was our top choice because it has it all at an affordable price. Even though it is a little noisier than some models, its powerful compressor offers the continual dehumidification in areas of up to 4,500 square feet and can drain forcefully in an upward direction through a 16-foot hose.
Our third choice is the technologically sophisticated Tosot 70 Pint Dehumidifier with Internal Pump, which has a programmable LED display as well as a very quiet internal compressor operating at only 50 decibels, making it one the quietest of the best dehumidifiers with a pump.
