Dehumidifier with Built In Pump

Sometimes a dehumidifier with a built in pump is an essential feature, and not an added luxury. Unless of course you feel like squeezing yourself in the crawl space three times a day to empty the holding tanks. The same holds true for bigger dehumidifiers like the basement models. Since most units will shut off when the bucket is full, the automatic pump will ensure that the unit is performing at optimum.

Water will ideally be pumped into your yard, but the hose can be snaked through a vent, window or discharged into a sink or drain hole.

Things to Consider when Buying the Best Dehumidifier with Built in Pump

  •  Drainage System: At the very least, most dehumidifiers have a drain hole at the bottom of the bucket. In this case, the dehumidifier needs to be elevated in order for the water to flow downhill to a drainage area. Needless to say, this is not an option when the dehumidifier is placed in the home. A dehumidifier with a pump can send water up through a window or drain, so you are not bound by gravity.
  • Electricity Consumption: Bigger dehumidifiers are more cost effective than their smaller counter parts, that much is true. However, in a place like the basement or crawl space, the units will be working hard, and running most of the time. Buying one of the energy efficient models makes financial sense. To save money and energy, these models will also switch off when the ideal level of humidity has been reached.
  • Drying Capacity: This refers to the amount of moisture the unit is capable of sucking from the air. If you buy too big, you will be paying for more than you need. However, buy one too small, and it will run constantly to try and maintain the desired humidity level.
  • Placement: It is very important to know where the dehumidifier will be placed in advance. A unit with a build in pump needs to be placed close to a drainage system, window, vent or sink. This unit will not work if there is no outlet for the collected water.
