A dehumidifier that includes a pump is rare but useful. They are especially useful in portable dehumidifiers for home use and for outdoor use, in a second home or on a boat. You do not always need a dehumidifier pump and even the instances when you do, the dehumidifier is not always the only option. Dehumidifiers are able to remove water vapor from the air around you by condensing it into liquid. The bucket in which this water is collected needs to be emptied at least once or twice each day. The dehumidifier will fail to work if the bucket is full. If it remains full it will allow the humidity to rise again, which defeats the aim of a dehumidifier.
It may not always be convenient to empty the bucket and for many it may be considered another chore that nobody needs. Every humidifier that has a good name has continuous drainage capability. The water comes out of the small outlet port in the dehumidifier casing. If you attach a small hose to this outlet the water will run to the nearest convenient drain. This will eliminate the need for emptying this bucket. This is all you need for most humidifier use. The flow of this drainage water depends on gravity and this is often a problem in a dehumidifier. For drainage to be effective it is essential that the drain is close to the appliance and below the outlet level. The dehumidifier will stop working if the bucket is unable to drain and remains full.
It is when the only convenient drain is at a higher level than the dehumidifier or some distance away that a dehumidifier condensate pump is required. This pump will force the water from your dehumidifier either to the floor or over a greater distance to the nearest drain. There are two solutions for this problem. You can either purchase a dehumidifier that already has a pump installed, or you can buy a separate dehumidifier pump. It is essential that before you make this purchase you carefully check that the dehumidifier and the pump have sufficient power. You will need a dehumidifier pump with a vertical lift of at least fifteen feet if you have to raise the water to a higher place, above the dehumidifier location.
A dehumidifier pump is essential when you use a dehumidifier on a boat or any other location that is away from your home and there is no convenient floor drain. There is much controversy about whether the draining water from a dehumidifier can be directed into the bilges with no risk to the vessel. For this reason it is important to use a pump. Selecting a dehumidifier with a pump or a separate condensate pump will depend on which you prefer. Although a dehumidifier with a pump is more costly than without, you will have restricted choices. However this dehumidifier with a pump is a lot simpler and neater to set up. A separate pump is an additional cost and not as tidy, but if the dehumidifier stops working you will at least still have a pump. If you want to know what the best dehumidifier with a pump is, you need to do a little research, but your choices may be limited. You can always buy one with a separate pump or an installed pump.
