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.

Too high humidity will cause mold, which will in return cause mold toxicity symptoms in your family. And hospital bills!

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 pump 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, 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. 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 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. 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.

70 pint dehumidifier with pump

70 pint dehumidifier with pump

If you have had flooding in your basement, you definitely need a high capacity dehumidifier. You could go with the Frigidaire 70 pint dehumidifier. It is one of the best dehumidifiers for mould.

If your basement is a bit deep and there’s a vertical height to overcome to drain the water, a unit with a pump can do great.

A dehumidifier with a pump will pump water out on its own. Therefore, you do not have to be there to empty the bucket manually.

Today, you can order a dehumidifier that has an integrated pump. There are many of them on different online marketplaces.

To cut to the chase, you can order the 70-pint Honeywell dehumidifier with integrated pump on Amazon.com. It is a high capacity unit that has a huge space rating of 4000 square feet. This is indeed perfect for a large basement.

15-foot hose drain hose and other features

It is an auto-drain dehumidifier, so you can connect the drain hose to the kitchen sink or out the window.

Even if the water has to go vertically, the in-built pump is going to kick in and pump the water upwards. For this, it comes with a 15-foot hose.

This is different from the basement dehumidifiers with drain hose only (without pump) since they come with a 6-foot drain hose mostly.

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.

There are other 70-pint or higher capacity dehumidifiers with built-in pumps. Some are from Midea, AlorAir, VellGoo, IVATION, Waykar, TOSOT, and Black + Decker. You can check all of these on this page on Amazon.com.

GE dehumidifier with pump

GE dehumidifier with pump

When looking for the best dehumidifier with a pump, you will definitely find one or two from GE Appliances ranking high on the list.

GE Appliances has been in business for more than 100 years. This brand name is renowned for making high quality, advanced and futuristic appliances for humidity control, kitchen and others.

When the filter is dirty, the dehumidifier alerts you. It also has convenient features such as pocket handles for easy transport.

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.

When it comes to dehumidifiers with pump, most of them come with drain hoses that are 16 feet long. However, you can extend your drain hose to make it longer.

You can watch the video below to see how to use a dehumidifier with a garden hose:

You can also attach a garden hose to the dehumidifier and the pump will still do a great job of disposing of the water. However, built-in pumps might also have a limit. Even if you have to extend, do not make the hose extra long.

What is a continuous drain dehumidifier?

What is a continuous drain dehumidifier

A continuous drain dehumidifier means that the unit is connected to a drain hose. This is just another name for a dehumidifier with drain hose and/or pump.

The hose takes the water away when the condensate pan gets full. Therefore, you do not need to empty the bucket.

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.

Such units will drain the water well when the drainpipe has a vertical inclination. The water flows out through gravity. If the hose is bent, it will not drain the condensate and the dehumidifier will stop working.

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.
