Benefits of Using A Dehumidifier with Drain Hose in the House

If you have experienced flooding in your area and your basement is extra humid, you need the best basement dehumidifier with a drain hose.

A dehumidifier with a drain hose extracts moisture from your indoor air consistently. You don’t need to empty the bucket, so you don’t interrupt its operation. 

In another article, we looked at the pros and cons of whole house dehumidifiers. One thing that we learned about such units is that they are in-wall or integrated into the HVAC system.

You never need to worry about emptying the dehumidifier, even if you live in a humid place like Florida.

In this article, we are going to look at the benefits of portable basement dehumidifiers with drain hoses.

There are several!

But first, if you just want to buy a dehumidifier with a drain hose, here is a table with a few such units:

How does a dehumidifier for a basement with a drain hose work?

Generally, what we are asking is: how does any portable dehumidifier with a drain hose work?

If this is your first time to read about dehumidifiers, these appliances draw water from your indoor air. In your home, you have to maintain the relative humidity level at 30 to 50 percent.

Thus, these units are used in humid places such as Seattle or in many other places that experience high humidity in the summer.

Dehumidifiers draw moist air using suction fans. This damp air then passes over the condenser coils where the water condenses.

After removing the moisture, the dehumidifier will blow back hot and dry air into the room. Basically, that is how all dehumidifying units work—portable or integrated.

By design, portable dehumidifiers come with a bucket. It holds all the water that it collects. Big dehumidifiers, such as the Frigidaire 70-Pint Dehumidifier, come with large buckets.

However, no matter how large the bucket is, it will eventually fill up, especially in a very damp or flooded basement.

If the bucket is full, the dehumidifier goes off automatically. It cannot collect more water. Thus, humidity persists, and it can cause mold.

How does a drain hose work on a dehumidifier?

A drain hose dehumidifier comes with a complete kit for drainage. This includes the hose and other accessories.

The unit will have a threaded spigot, which connects to a hose. The water will flow through the hose to the sink using gravity (for wall-mounted and countertop dehumidifiers with hoses).

There is also the option of buying a dehumidifier with a drain hose and pump. If it has a pump, it will not depend on gravity to drain the water it collects. Some pumps can pump water for meters vertically.

A dehumidifier with drain hose can work consistently for hours

There is a solution in the dehumidifiers that come with a drain hose. Instead of using the bucket to hold the water drawn from the air, you can connect a drain hose that drains the water outside.

That way, you don’t need to empty the water. It will drain outside to the garden or to the drain system. Remember, you can also use dehumidifier water to water plants.

If you have had flooding in the basement, you probably need to run the dehumidifier for several days or weeks to dry the walls and the floor completely.

Unless you use a unit that has a drain hose and pump, there will be too many bucketfuls of water to empty.

This can result in time-wasting. Besides, if the unit keeps stopping, it will not do a good job of pulling moisture out of the air.

Types of dehumidifier with drain hose

Dehumidifiers with drain hoses come in different forms. We have wall-mounted, countertop, small, and basement dehumidifiers with draining hoses.

Here is a brief look at each of these dehumidifier types:

Wall-mounted dehumidifier with drain hose

As the name suggests, you mount this type of unit on the wall. They have their benefits, such as a low noise level, minimal space consumption, and no cable clutter.

Usually, in-wall units are also called whole house units. Once installed, it will always draw water from the air and drain it away. This is easily the most hassle-free unit you can buy.

These are large-capacity dehumidifiers that can remove up to 160 pints, or more, of water a day. They also come with a built-in humidistat. Such a unit can start removing moisture from the air automatically when the humidity level exceeds the set level.

The initial installation of such a dehumidifier can be expensive since you require a technician. You will also require a professional to maintain and repair it if anything goes wrong.

The benefits outweigh the disadvantages by far, so it is definitely worth having.

Countertop dehumidifiers with drain hose

It is possible to find a compact dehumidifier with a drain hose. Such a dehumidifier will not be possible to connect with a sump pump. You will have to connect the drain hose to the sink so that it can drain water outside using gravity.

You can also direct the hose to the floor drain. These units are small and portable, so you can move them from one place to another.

Remember, the best place to position a dehumidifier is about 3 to 6 feet from the source of the damp air.

Make sure the hose is straightened out, since kinks can prevent proper drainage. Direct the hose to the place where you want to drain the water.

If you want to direct it outside the window, you will have to place the dehumidifier higher so that the hose drains the water using gravity.

A small dehumidifier with drain hose

If you wish to dehumidify small spaces continuously, you might want to try a small dehumidifier with a drain hose.

To protect your leather items from high humidity damage, you might want a small dehumidifier with a draining hose for your closet. Such a unit will run all the time, removing excess moisture and protecting your shoes and clothing.

Such units can also come in handy for boats, RVs, cars, and other small spaces. Perhaps you would also love to use such a unit in your bathroom space.

If you ignore dehumidifying these small spaces, you will let mold colonies flourish. They will then produce mold spores that will float through the air to other parts of the house.

The best size for basement dehumidifier with drain hose

How big should a dehumidifier for the basement be? This question is popular with many people.

This depends on the size of your basement. Remember, portable dehumidifiers have a space rating so that they can work effectively.

For instance, if a dehumidifier has a space rating of 1500 square feet, use it for that space, or a bit smaller. If you use it in a larger space, it might not do a very good job of removing excess moisture from the air.

You can also get a dehumidifier based on the number of liters of water it can hold. For instance, you can use a 4.7-liter dehumidifier in a space of 500 square feet.

For a space of 1000 square feet, use a dehumidifier with a capacity of 6.6 liters.

The good thing is that even if your basement space is 4500 square feet, you will still find a dehumidifier for it. Some portable dehumidifiers for the basement can work in spaces as large as 6,000 square feet.

Wrapping Up

Choosing a basement dehumidifier with a drain hose has many benefits. Too high humidity is going to cause mold growth in your basement. A dehumidifier will prevent this.

A dehumidifier connected to a drain hose is going to remove moisture from the air consistently. It is very helpful after flooding.

Some of these dehumidifiers can come with sump pumps so that they can force water to drain outside against gravity.

Some are enough for large basements, running up to 6,000 square feet, and some are perfect for small spaces.

Irrespective of your budget, you will get a good dehumidifier with drain hose for your needs.
