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

If you use a dehumidifier without a pump in a large space, you will have to manually empty the dehumidifier tank manually when it is full. This means you have to stop the unit first, remove the bucket, and pour out the water.

Dehumidifier with Pump Vs No Pump: Main Differences

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. It will automatically pump the water outside your house, or through the sink waste pipe.

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

1. The pumping unit can push water vertically

The pumping operation is electric, so this unit can drain water vertically without missing a beat. These units can push water to a vertical height of up to 15 feet.

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.

A unit without a pump cannot pump water vertically. You can only connect it with a hose, so the water can flow with gravity.

2. There is no reservoir to empty and no downtime

If a dehumidifier lacks a pump, the bucket has to be emptied manually. You’ve got to remove it, empty the water into a tank or pour it outside, and then return the reservoir.

This is hard work. It also wastes precious time and can even make the humidity to rise again.

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. The pumping unit uses more electricity

Because of the pumping action, the dehumidifier with a 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.

If cost is a concern for you when it comes to dehumidifier pump vs no pump, go for one without.

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 something to consider.

Once you set this unit up, it operates pretty hands-free. You can even travel and leave it to lower the humidity in your house appropriately when you are away, to protect your leather items and electronics.

It comes with a digital humidistat. This monitors the humidity level. If it rises above the set threshold, the dehumidifier starts automatically to draw moisture from the air.

Dehumidifier drain hose maximum length

For a dehumidifier with drain hose alone, without a pump, the length is usually 6 feet. Experts advise that the length of the hose should not exceed 5 feet.

If it is longer than that, the pressure will be low and it might not dispose of the collected water easily.

With such a dehumidifier, you would have to place it on the kitchen counter, so that the hose can reach the sink.

You can also place it on a table close to the window so that the drain hose disposes of the water outside. However, remember the best position for a dehumidifier is a foot or more away from walls or furniture.

A continuous drain dehumidifier works with a drain hose as well as a pump. Well, some just have the drain hose and not the pump.

A dehumidifier with a built-in pump such as the few that we have looked at here is also a continuous drain type. They can drain the water vertically easily and over long distances.
