Dehumidifiers For Home Use - What's Available?


What is humidity? Well, water comes in three forms: liquid, vapor, and ice. Humidity is the amount of water vapor in the air, known as relative humidity (RH). If humidity exceeds 100%, moisture will begin to condense from the air. So if the air contains only half the water it can hold at a certain temperature, the relative humidity would be 50%.

We can measure the RH with a hygrometer. If you keep your air conditioning unit on all summer and the windows and doors closed, check the relative humidity in various rooms throughout your house with a hygrometer. A good rule of thumb is, if your relative humidity reads above 50%, you really should have a dehumidifier to take away excess moisture.

Choosing the type of dehumidifier you need depends on your environment. Lets look at the more popular types of dehumidifiers on the market for home use.

A dehumidifying ventilator works with an exhaust fan and sensor controller. The sensor controller is adjusted to turn on when humidity rises to a predetermined level. This can be very effective in a basement or crawlspace.

Another type of dehumidifier is the chemical absorbent, which is best suited for hot and human climates. An example of this is silica gel.

Theres' also a heat pump dehumidifier. These machines usually have two sets of coils, a motor fan that moves air through it, a control panel and a water bucket or drain system. These types of the humidifiers are very efficient, but can be fairly expensive, use a fair amount of electricity, and may be noisy.

One thing to look for is a high efficiency factor rating. The Energy Star ratings can save you some money in the long run. A Look for a dehumidifier with frost free option. Also, the better dehumidifiers have a built-in humidistat and shut off feature.

Having casters on your dehumidifier can turn out to be very handy when you want to move the unit to a different room or a different spot in the basement. A dehumidifier that has a capacity of around 60 pints would weigh almost 55 pounds, so rolling it instead of carrying it to a new location is highly desirable.

There are several manufacturers of home dehumidifiers. Popular manufacturer names are Kenmore, Santa Fe, Home Comforts, Soleus, Fridgidaire, and others.

Expect to pay anywhere from around $140 for a 25 pint dehumidifier to $250 for a 60 pint model.

I've always enjoyed doing home improvements and with a basement full of valuable tools and other items, I can keep the air at the proper relative humidity with a good dehumidifier.

Different Types of Basement Dehumidifiers


Basement dehumidifiers are an excellent way to reduce the humidity levels in your home caused by moisture in the air. High humidity can cause serious damage to your home in several different ways. For one thing, it can cause mold and mildew to grow on walls, baseboards, under carpets and many other areas of the home. This creates poor air quality that can cause respiratory diseases or make existing ones worse.

If your basement smells musky or you see signs of mold and mildew, then it's recommended you purchase a dehumidifier for your home. There are many different types and sizes available to choose from making it possible to find the one that is best suited for your needs. Here, you'll find information about the most well-known types of basement dehumidifiers so you can have a general idea of what options are available to you.

Whole basement dehumidifiers are designed for large areas to ensure coverage for the entire space of the basement. The storage unit on these can hold more water but the system will still shut down if the tank is not emptied regularly. However, since it's a large unit, the storage tank can usually hold a lot water before the unit will shut off automatically. Portable dehumidifiers are small and easy to use. This makes them great for small basements and even other parts of your home where moisture can be a problem such as bathrooms and closets. However, since these units are small, the tray that holds the water will be small as well and it'll be necessary to keep a close check on it to make sure it's emptied regularly.

Dehumidifying ventilators are designed for basements, crawlspaces and attics because they use a sensor to keep the humidity in the area at a specific preset level. Wall mounted dehumidifiers can be used in these same areas as well and they do an excellent job keeping the humidity down. These are just a few of your options and there are many different sizes to choose from too. You can use the Internet to search basement dehumidifiers to get a more detailed list of the different ones available. This will also help you determine the type and size that would be best suited for your individual needs.

Many basement dehumidifiers can be set up where they will drain into a sink so you don't have to worry about emptying the water tray. If you don't go into your basement on a regularly basis, this might be the best option for you. Just remember to check on it from time to time to make sure everything is still in order.

The price for dehumidifiers for home basement use does vary a great deal. You can read reviews on the different types of dehumidifiers to see what other homeowners have the say about the unit they used and if they felt like it was worth the price they paid for it or not. In most cases, basement dehumidifiers save so much money in home remodeling projects and doctor bills that they more than paid for themselves in the long run regardless of the price.

What Are the 3 Types of Dehumidifiers?


Hot and sultry, muggy and sticky, there's nothing worse in the summer time than the heaviness of the humidity. In fact, for some states it's so bad, that you are drenched in moisture just to take a walk to mailbox at the end of your short driveway. And, when that humidity makes its way indoors, the days and nights can seem virtually unbearable. Fortunately, there is a solution. Invented by Willis Haviland Carrier in 1902, dehumidifiers soon became the ideal way to cool one's home. Over the years the dehumidifier as evolved and today there are 3 main types of dehumidifiers.

All humidifiers work on the same basic principles, though each one varies somewhat based on the type. Like an air conditioner, the dehumidifier uses refrigerant. However, it does not cool the air...it actually warms it slightly which decreases the humidity thus making the room more comfortable. This is done by a fan, hot and cold condenser coils and a water reservoir.

The heat pump dehumidifier is used to pull out water form a building by using a heat pump which works much like an air conditioner pump. A fan is used to move the air across a frigid coil causing the moisture to condense. Then the droplets are collected in a bucket inside the unit. The air is then warmed by a second coil and then released back into the room at a comfortable temperature. The heat pump dehumidifier is considered the best one available.

In large industries, especially those in warmer climates, the most common type is a chemical absorbent dehumidifier. This type uses a chemical drying agent that works with a heat exchange wheel to absorb the water molecules from the air. The process pulls the damp air outside through the vents.

The third type of unit is the dehumidifying ventilator. These work with a sensor controller and an exhaust fan. These are less effective in climates where the humidity is especially high because the ventilators draw outside air into the house. Rather, the dehumidifying ventilator works great in basements but you must pay close attention to how it is working as it can depressurize a room and can cause gas spills...just be sure that if you have a gas furnace that it is properly vented and you will fine.

If you already have a dehumidifier, but it does not seen to be working correctly, there are a few things you can do. First you will want to make sure that it is the right size unit for the space it is cooling; then after you have turned the unit off, check the following:



Remove the cover clean the condenser and the evaporator coils.

Lubricate the fan motor bearings, if the motor has oil ports.

Make sure the humidistat is working properly by testing it with a volt-ohm. Rotate the humidistat's knob as far as it will turn in either direction. If it reads 0 throughout the process then it is time to replace the unit.

Dehumidifiers - What to Look For When Buying


Dehumidifiers help maintain a more constant level of humidity in the home. They remove the excess moisture created by activities such as cooking, showering or boiling the kettle. High levels of humidity can cause condensation, damp and mold as well as being an ideal breeding ground for dust mites. All of these things can create an uncomfortable living environment for people with conditions such as Asthma and Arthritis. Also a more humid home is harder to heat and will therefore attract higher heating bills. Investing in a good dehumidifier will solve many of the above mentioned problems. Listed below is a quick guide to assist in selecting the correct device for your home.

A key feature to look out for is the extraction rate of a dehumidifier. This is an important factor in determining how effective the machine will be. The figure is quoted as the amount of water, in litres, which can be extracted in a 24 hour period. In the UK, a typical 3 bedroom home requires a dehumidifier with an extraction rate of 18litres/24 hours or above.

Some models have an auto-stop feature allowing the unit to stop when the water tank is full. Others can be fitted with special plumbing kits to provide a permanent drainage facility. Variable speed settings and humidity sensors adjust the extraction rate of the device based on the moisture level in the home. Another useful feature is a boost setting for drying laundry. As these machines need to operate for prolonged periods of time and possibly overnight, check models for energy efficiency and noise level.

A good domestic dehumidifier will cost around £130-£180. Judging by the low stock levels of high street and online retailers last year, the dehumidifier seems to be a very popular choice for dealing with what appears to be a common problem in condensation.




Almost all homes will experience excess moisture levels at some time. For tips on selecting the right dehumidifier and reducing condensation, visit http://streamingwindows.blogspot.com

Introducing Dehumidifiers and their Function


Dehumidifiers use a heat pump (similar to an air conditioner's heat pump) or chemical adsorbents to remove moisture from the air without cooling the air.

A heat pump dehumidifier uses a fan to draw indoor air over a heat exchange coil. The coil is almost freezing. The water in the air condenses on the coil and is drained. A second heat exchange coil reheats the air, which the dehumidifier exhausts into the room.

A heat pump dehumidifier dumps heat lost from the compressor and fan motors into the air. It returns to the indoor air the heat generated by the dehumidifier turning water vapour to liquid.

Chemical adsorbent dehumidifiers

This type of dehumidifier is designed for hot, humid climates and is not really suited for use in Canada.

Chemical adsorbent dehumidifiers absorb moisture from the air with a "desiccant"--a drying agent such as silica gel. The desiccant is on a heat exchange wheel. A separate air loop dries the wheel and exhausts the hot, damp air outdoors through special ducting.

A chemical adsorbent dehumidifier uses more energy than a heat pump dehumidifier. It is only cost-effective when it uses natural gas for heat exchange--and then only if natural gas is available at a low summer rate.

Homemade dehumidifier

Some inventive people use bags of road de-icing salt to absorb moisture from the air. The wet salt solution drips into a pan or floor drain, drying the air. Because the salt runs off with the water removed from the air, it must be replaced. The system has no moving parts.

If you try this homemade dehumidifier, remember that salt is highly corrosive to metals and quite hard on the skin.

Dehumidifying ventilators

This type of dehumidifier has a sensor-controller and exhaust fan. You set the sensor-controller to run when humidity reaches a set level. A dehumidifying ventilator is particularly effective if the humidity source is in your basement.

Dehumidifying ventilators don't recover heat but they use less electricity than heat pump dehumidifiers. They are not effective in hot, muggy weather, as they bring more outside air into the house. They can be effective in cold weather.

A dehumidifying ventilator depressurizes your basement, which can cause combustion gas spillage. Make sure your heating contractor checks the venting for your gas furnace, water heater and wood-burning appliances. Consider using a carbon monoxide warning device if you install a dehumidifying ventilator.

Choosing a Dehumidifier

Dehumidifier purchase costs

Heat pump dehumidifiers are complex, low-production machines and are not low-cost items. Spring seems to be the best time to buy: in the last few years dealers have held sales early in the spring with savings of $50 to $100.

The more water a dehumidifier holds --which is measured in litres or U.S. pints a day--the more it costs. You pay more for special features.

In 2000, you can expect to pay between $200 and $250 for a unit rated at 10 L (21 U.S. pints or 2.1 imperial gal.) a day--suitable for a small house with a moderate moisture problem. The price rises to between $250 and $350 for a unit with a capacity of 20 L (42 U.S. pints or 4.3 imperial gal.) a day--suitable for a large house with more severe problems.

Running costs for both units are about the same if they both have the same Efficiency Factor. The next section explains the Efficiency Factor.

Don't try to save money by buying a unit that does not have automatic defrost. If a room is too cool, a dehumidifier can frost over and stop removing moisture. A frosted-over dehumidifier left running for a long time will break down.

Get a unit with a two-speed fan. They are quieter at lower humidity, which reduces the nuisance factor. Test all units in the store for noise level, especially if you plan to use one in or near a bedroom.

Dehumidifiers: The Key to Keeping Moisture Out of Your Home


A dehumidifier is used to remove extra moisture from the air. It cools a hot and humid room by reducing the amount of moisture within the room. A dehumidifier consists of a number of hot and cold coils which are involved in the process of dehumidification.

The evaporation cycle of a dehumidifier works in the following way:

A built in fan draws air from the room over the cold coils of the dehumidifier. The saturation vapor of water decreases as the temperature decreases, causing the water in the air to condense, which then drips into a collecting bucket. The dry air then passes through the hot coils of the dehumidifier to attain the previous temperature.

Most dehumidifiers are able to be adapted to connect the drip output directly to your drain. Dehumidifiers may be priced solely on the size of the bucket which collects the water. Usually there are sensors which will detect when the bucket is full.

The usefulness of a dehumidifier depends on the amount of humidity and the distance you are from sea level. In areas near sea level, the humidity levels will be higher.

Water collected from any dehumidifier is not safe to drink. It is distilled water, as it does not contain minerals and other particulates that are removed in a true distillation process. However, a true distillation process will condense the steam of boiled water, and the boiling process will kill any microbes and fungi that may be present in the water beforehand. Since the surface coils in a dehumidifier are not kept to food-grade cleanliness, microbes and fungi can (and most likely do) exist in the collected water, which is why it is unsafe to drink. Furthermore, as the water may sit for quite some time in the collection bucket, it may be quite stale.

There are three prominent reasons that make it important for a home to have a dehumidifier. These are as follows:

o A dehumidifier proves helpful in reducing humidity, and consequently protects the building as well as personal belongings from being damaged due to dampness and mold.

o Reduced moisture results into a significant reduction of mold spores and house mites. Asthma gets aggravated due to the waste left by house mites that live in bedding. A dehumidifier helps to maintain humidity levels below 50 percent. Consequently, it leaves a positive effect on the respiratory system and allergies.

o More energy is consumed when heating up air that contains moisture, than what is needed to heat air that is dry. This is due to the fact that moist air is heavier. If the air inside the house is kept below 50 percent relative humidity, then the house can be kept several degrees warmer using the same amount of energy which was used prior to the use of a dehumidifier.

So, to summarize, a dehumidifier is a very beneficial piece of equipment to have in any home.
