About Dehumidifiers

Chuck Jaymes asked:


Humidity and moisture in your crawl space can often lead to a serious problem for homeowners not using a crawl space dehumidifier; wood rot. Wood rot, also called wood decay, is caused by microscopic organisms that belong to the fungi group. These organisms are what cause the wood to actually decay.

Wood is comprised of 3 major components: cellulose, hemicellulose and lignin. Wood rots because the fungi “eat” these 3 major components of wood cells by releasing enzymes that digest wood cells.

Wood that has a moisture content of 20% or above is very susceptible to rotting. The attacking fungi require 4 conditions for colonization:

1) Adequate oxygen supply

2) Temperature range between 40-100 degrees Fahrenheit

3) Constant moisture source

4) Adequate supply of food (wood)

Untreated moisture damage can cause a decrease in your property value by 10% to 15% according to the National Association of Waterproofing and Structural Repair Contractors (NAWSRC).

Catching moisture problems like wood rot in the early stages will save you both money and headaches. There are several warning signs to alert you that moisture may be damaging your home: excessive condensation on windows, blistering or peeling paint, discolored wood surfaces, splits across the wood grain, mold spots, musty odors and standing water in your crawl space.

If you notice any of these warning signs, you need to determine where the moisture is coming from. Check for plumbing leaks, roof leaks, debris filled gutter and downspouts, foundation cracks and poorly graded soil that drains towards your home. In your crawlspace, look for mold stains on the foundation walls and/or puddled water.

Moist, humid air from your crawlspace increases the moisture content of the wood in your home, making it vulnerable to wood rot. By installing a vapor barrier and a high grade crawl space dehumidifier, you can protect the value of your home.

On the side of my furnace there is an vertical pipe the connects to a pipe that runs all the way across the room and into the drain.

Normally my dog isn’t allowed down there because he hides stuff in the gravel pit and spreads gravel everywhere. Today he managed to disconnect the pipe, which apparently isn’t glued together. And now I have wet gravel everywhere. Which is just making the basement an even more dank hell-hole that I don’t want to deal with.

Now as far as I know most people don’t have pipes running from their furnace across the floor. So can someone tell me where, in a normal house this pipe is supposed to go? And whether I can do that kind of plumbing hookup relatively easily myself?

If I can’t do it easily is there any reason this pipe isn’t at least f$%&ing glued together? And shouldn’t the vertical pipe have a cap on the top to stop cr@p from falling in it?
ou can see a picture of the pipe where it is attached to the furnace and where it “connects” to the drain here:

And yes, I know my basement is a flaming mess.

Excessive of anything is bad for your health, and the same goes for humidity in your home. Coupled with the heat of summer, humidity beyond the ideal figures of 30-50 percent in your house can cause numerous problems to your health. Respiratory problems such as flus and colds are caused by the environmental changes encouraging the growth of mold spores and dust mites. Moreover, damage to stored food items, furniture and other home appliances can happen from excessive exposure to increased levels of humidity.

The telling signs of excessive humidity are condensation on windows, wet spots on walls, ceilings or tiles. If stuffiness is felt or the air has a musty smell or odor, there is an increased chance of allergies etc and a dehumidifier is usually needed. Dehumidifiers are the easiest way to avoid such problems. Available in a variety of sizes and types they work in the same way i.e. they draw in humid air, dry it, retain the water for later discharge and release the dryer air into the indoor area. This process also results in bringing down the temperature as well.

Dehumidifiers are usually portable to be moved from one room to another in order to get your whole dehumidified. The increased electricity bill will pinch if used around the house in such a manner but considering the damage to one’s home and family, it is well worth it. It is also important to empty the device in a regular basis as the stagnant water or residue attracts bacteria and germs thus defeating the purpose of the device.

Due to the different types of dehumidifiers available, one has to prioritize the areas of your home to dehumidify. First priority is given to basements as they are prone to excessive humidity. Basements dehumidifiers are therefore among the commonest followed by similar devices in places like laundry rooms. However, in climates where humidity is a lot everywhere in a house, living room, dens or recreation rooms are prime candidates for which smaller portable devices are ideal.

Besides getting a dehumidifier of a capacity according the place where it is used, proper maintenance is necessary to keep it functioning properly as mentioned before. One factor enabling better upkeep is the relative humidity outside the house, which will dictate whether more care is needed or not. For example a clogged filter will make bacteria grow more easily or a make the device function less efficiently, thereby reducing capacity to dehumidify a room and also using more electricity.

Another important factor is the extent of control over your device. For this it’s important that you ensure your dehumidifier has a hygrometer and humidistat to control the precise percentages of humidity levels in the air. Although they might not be available in smaller models, they are indispensable in larger ones. Furthermore, dehumidifiers that have convenient ways of discharging excessive levels of water are easier to use and maintain.

When most people think of portable air conditioners, what comes to mind is usually basic information that’s not particularly interesting or beneficial. But there’s a lot more to portable air conditioners than just the basics.

With the onset of the damp weather, it becomes difficult to survive without constant central air conditioning but that can prove to be quite expensive. The answer to this problem is a portable air conditioner as it has many advantages. It is easy to shift from one place in the home to another and that makes a portable air conditioner the ideal cooling system solution for your home, office or industrial site.

The portable air conditioners are easy and quick to install, as they do not involve any lifting or tearing up of windowsills. Moreover it can be shifted very easily from one place in the home to the other. For taking care of the hot spots in the central air conditioning, the portable air conditioners are far more convenient than window air conditioners. It is also ideal for window shapes, which present problems for installation. There is nothing like portable air conditioners for use as a spot cooler in the home.

A portable air conditioner is an excellent choice for saving money as just one unit needs to be purchased and it can be shifted easily to where you need it as it is mounted on castors and some can weigh only about 36 pounds. Moreover, as only one room is cooled at a time instead of the whole house, the total energy consumption is very low as compared to other air conditioning systems.

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

Another advantage of portable air conditioners is the energy efficiency that they provide. The average efficiency is in the 8 to 10 range although some are as high as 15, which is 50 percent better than most older central air conditioners. The small size of the portable air conditioners is very advantageous and as such it can fit in a corner or against a wall. It functions like an effective dehumidifier if you do not vent the warm exhaust air out through a window and its size is also the same as that of a room dehumidifier.

In order to reduce humidity and allergies, even the small ones remove 35 pints of moisture per day from the room air. The portable air conditioners also use the heat-exchange principle as the other air conditioners to cool and dehumidify the air. The operating principle is also similar to a window air conditioner as the room air circulates over cold evaporator coils to cool and dehumidify it inside the unit. The room air is exhausted outdoor after flowing over the hot condenser. There is no chance of already-cooled indoor air escaping outside as two ducts are now used.

Nowadays, you have electronic controls in most models and you can set the desired room temperature, blower speed, start and stop timer, and operation mode (cool, dehumidify, heat). The portable air conditioners also have hand-held remote control with which you can conveniently change all the settings as per your need.

The other features of portable air conditioners include a built-in air cleaner with an optional charcoal filter and oscillating louvers to distribute the cool air throughout the room. You can also switch off the louvers to direct the flow of air towards yourself, if you so desire.

The day will come when you can use something you read about here to have a beneficial impact. Then you’ll be glad you took the time to learn more about portable air conditioners.

Barney Garcia asked:


Although the air conditioner is here almost for a century, the market for the device, especially the domestic market, is seeing a surge that it had never seen before. This can be attributed to various reasons. While some claim that more people these days have more disposable income which allows them to invest on these devices, there are others who believe that global warming and increased temperatures all over have pushed the sales for air conditioners upwards.

Whatever may be the reason, the fact is that sales have increased and those who are in the business of selling air conditioners are trying to make the most of this opportunity. This would make them claim things which are not completely true. They can even claim that air conditioners come with features, which upon investigation might prove to be completely false. So guard against what you are being told. It is your duty to be mindful. If you are duped, much of the blame rests with you.

Many air conditioner sales person would claim that their air conditioner dehumidify the air. Let us examine how much truth is there in their claim. It is a fact that air conditioners do actually dehumidify the air to a certain extent. The evaporator coil inside the air conditioner which is a below the dewpoint can actually condense the water vapor from the air that is being processed. So when the processed air is released into the room it is devoid of the water vapor that was there in earlier.

But this is by no way the primary function of the air conditioner. Its job is to maintain a temperature. That it dehumidifies is a bonus. But since dehumidifying is not its job, the amount of dehumidification it actually achieves is also limited. This can vary from anything between 40% to 60%.

If you are really keen on dehumidifying the air of your room then you must invest on a dehumidifier itself, a device dedicated to this job. The results you will achieve are much better.

So while buying an air conditioner, keep in mind why you are buying it. It is not for dehumidifying. If however, you feel that your conditioner does enough of dehumidifying and you are happy with what the air conditioner achieves then it is good for you. but never ever buy an air conditioner with the misconception that it will double-up as the dehumidifier.
