What is the difference between a dehumidifier with a pump and without?

When you go out to buy a dehumidifier, you will find so many options out there. Some are big and some are small. Some are also whole house dehumidifiers that are integrated into the furnace.

If you are dealing with a lot of humidity at home, you will probably be considering buying a dehumidifier with an internal pump and a drain hose.

So, what is the difference between a dehumidifier pump vs no pump? The dehumidifier with pumping kit clears water automatically through a hose connected to the kitchen sink. The dehumidifier with built-in pumping is best for dehumidifying large spaces continuously.

If you use a dehumidifier without a pump for a large space, you will have to empty the dehumidifier tank manually when it is full. This means you have to stop the unit first, by removing the reservoir manually.

Dehumidifier with Pump Vs No Pump: Main Differences

If you live in a humid state like Florida, you really do need a large dehumidifier. More so, you need one that has an internal pumping mechanism so that it automatically pumps the water outside your house, or through the sink waste pipe.

Here are the main differences between a dehumidifier pump vs no pump:

1. Pumping unit can push water vertically

The pumping operation is electric, so this unit can drain water vertically without missing a beat. In fact, these units can push water to a vertical height of up to 15 feet and that is awesome. If you need to dehumidify the basement and push the water up a hose outside the house, get a unit with a built-in pumping kit.

Need we say that a unit without a pump cannot pump water vertically? Perhaps if you connect it with a hose, water can flow with gravity.

2. There is no reservoir to empty and no downtime

If a dehumidifier lacks a pump, the reservoir has to be emptied manually by removing it, emptying the water into a tank and returning the reservoir.

If the reservoir fills up when you are not home to empty it, the dehumidifier automatically stops drawing moisture from the air.

In places that have high humidity such as Seattle, this will not help much to keep the relative humidity to the required level of between 30 and 55 percent. However, you can buy a bigger unit to work in a small space.

3. Pumping unit uses more electricity

Because of the pumping action, the dehumidifier with built-in pump consumes more electricity because it does more work.

When you have to drain water over a long distance vertically, the pump consumes more electricity. In our article on do dehumidifiers use a lot of electricity, we said a unit could use $0.16 to $3 daily. If it has a pump and you use it more often, it can even use more than $3 a day.

4. Units with pumps are costlier

The TOSOT 50-Pint with Internal Pumping costs up to $300, sometimes more. In most cases, similarly sized dehumidifiers would cost at least $50 less. This might not apply to all brand names, but it is definitely something to consider.

Dehumidifier pump vs no pump FAQ

If your mind is still not made up about buying the dehumidifier with built-in pump, this section on the frequently asked questions might help you:

How does the pump on a dehumidifier work?

If it has a built-in pump, all you have to do is connect a hose to the port that is designed for just that. You can then direct the hose to a sink or point it out the window. If it does not have a pump, you can buy an external condensate pump and connect it easily so that it pumps water out automatically.
