Basement DehumidifiersBasement dehumidifiers are a great solution for damp basements after you have taken the proper measures to stop the moisture that enters. These measures are necessary in order for basement dehumidifier to perform as advertised. Basement dehumidifiers use the same technology as a refrigerator or air conditioner. Moisture (humidity) is drawn over the coils that cold refrigerant runs through. The moisture then condenses and either drops into a pan or through a hose to a drain. Dehumidifiers are rated for the ability to remove a certain amount of moisture in a day. Most manufacturers have guidelines as to the right size based on conditions and square feet of area. After you determine the size unit you'll need, you should look at the moisture removal capacity of various units. This is where you'll have to be careful. Some dehumidifiers are not capable of operating in certain temperatures. Most basements that I have been in are usually 60 degrees or lower unless it is a heated living space. Moisture removal capacity ratings can be tricky. Ratings are based on 80 degree temperature and 60% Relative Humidity. Of all the high capacity units, The Santa Fe Dehumidifier Of all the high capacity units, the Santa Fe dehumidifier manufactured by Therma-Stor LLC is rated at approximately 100 pints per day under the above mentioned conditions. They also know the reality that a basement is most likely to be approximately 60 degrees with 60% relative humidity. They are honest enough to let you know that the Santa Fe that is rated at 100 pints per day will only remove a little more than 50 pints per day in real world conditions. Check with the manufacturer to find out if their unit capacity is under less than ideal conditions. It could be possible the unit that is rated at 50 pints per day may only remove 25 pints per day. Another higher capacity unit is the Whirlpool Gold basement dehumidifier . It's rated capacity is 70 pints/day. While it may remove less moisture than the Sante Fe, there are a few things I like about it. It is an "Energy Star" rated unit, which means it operates efficiently. It also will operate in 44 degree air temperature. And lastly I like the price. At $295 it's a bargain. To purchase a Whirlpool Humidifier, click here. Another thing to look at is electrical consumption. Energy Factor is the amount of moisture removed per kilowatt hour. It is based on litres per kilowatt hour. Most units I have looked at have an Energy Factor of 1.5 to about 1.7. with the exception of the Santa Fe which is 2.7. This could equate to an energy savings of approximately $10 per month ($.10 per/kwh) depending on the electrical rate in your area. Even though basement dehumidifiers have a price range from $220 to $1500 ask the following questions: Will the unit operate at lower temperatures? Will the unit really give the capacity I need? What is the real cost of ownership (Initial investment vs. operating cost)? There is a difference between price and cost! Expert Air Purifier Reviews Home Page |
