According to the study, energy consumption residential USA (RECS) in the Us , the average American residence jednorodzinna consumes about 48% of the total energy consumption for heating and cooling homes. While this is lower than approximately 57% of the total consumption of electricity in the early ‘ 90s, thanks to better insulation and more efficient HEATING, ventilation and air conditioning systems, is still significant energy consumption and, consequently, the main part of the annual expenses incurred a family. just living my own life.
Cooled air in summer and hot air in winter are not usual luksusami; For convenience and safety is vital to maintain moderate living conditions in the house. This means the use of Central heating and cooling as soon as possible because these systems are ultimately the most efficient and cheap way of heating the house in winter and cooling it in summer.
The installation of a Central heating system and cooling costs much more than buying individual heaters areas or air conditioners wall, but in such systems, consumes less energy to achieve the same degree of cooling or heating, as an independent unit, and thus ultimately the costs of operation of a single unit will exceed initial cost of the Central system.
In addition to reliable cooling and heating, circulation and ventilation are also important aspects of maintaining safe indoor air. But because the poor quality of indoor air (or MAC) can lead to countless complications, including exacerbation of asthma, allergies, and even headaches, dizziness, fatigue, or problems of knowledge, in accordance with the Agency for the Protection of the Environment, again, it’s not a matter of ordinary comfort, but health and safety.
If your house has Central air conditioning and heating, just make sure that you replaced air filters in accordance with the recommendations and having a provisional rating system and cleaning professionals should be all that is required for a safe, clean indoor air, but if this system does not have ventilation in the attic and adding attic fan can be justified. In a house without Central air attic fan can not only make the decision to reduce the indoor temperature in the warm season, but can also help in the maintenance of air purity and cleanliness in his apartment.
The attic fan to regulate temperature
In the hottest days of summer, when the temperature of the air in the room is 90 or more, and the sun shines for hours on the roof, the temperature in the attic can rise to 150 or even 160 degrees Fahrenheit . The mixture of hot air, rising from the depths of the house, and the prevailing conditions on most of the attic, including solar heat from above, and often a lack of adequate insulation and poor ventilation, work to retain heat which, in turn, can dramatically heat the whole house. This means less comfort and / or means much greater use of HVAC systems, which causes excessive load of the equipment and increase electricity bills in the house.
Decent fan-attic can transfer tens of cubic meters value of air per minute, providing a complete “replacement” air ” is many times per hour. (Change of air occurs when the air in the space, in this case, the heated air in the attic is disabled in favor of the new air is naturally sucked in through the vents at the base of the movement with a fan.) The constant change of the air-cycle could see the attic temperature down to fifty degrees or more. This means, for example, that day, when it’s 95 degrees F, an attic fan without proper attic may have a temperature of 160 degrees, while an attic fan is only slightly more than 100 degrees. This means that the house below the attic will be even much, much cooler.
This attic fan that helps keep the attic (and residence) in summer much cooler, can also help alleviate one of the most common problems faced by the attic in the cold months: the accumulated moisture.
Fan attic to reduce moisture and mold
There are some words that the owner of the house wants to hear less than ” mold “. There are several conditions in which mold is more prone to growth than in the dark, damp space. If you ever-he stuck his head in the attic of a conventional house during late spring, summer or early fall, then you know that these two adjectives – and the dark, for example – are the perfect deskryptorami space.
Warm, moist attic in the summer, especially ripe for mold growth and mold , but the hot temperatures in the summer often prevents the accumulation of large amounts of moisture. In winter warm air flows out of the house, meets the cold air from the roof and vents, and often creates ideal conditions for capture forms.
To attic was free from mold, they should be protected from moisture. Starts with, to make sure that the roof is in good condition, as a leaky roof is the main cause of mold. No wonder another leading cause of mold in the attic is leaking pipes or malfunctioning furnace or water heater.
But even in the attic, with a solid roof and no leaky pipes, moisture still be a problem without adequate ventilation. Attic fan can help to suck moisture from the air and maintain the air flow necessary to maintain a dry environment in the attic. but because the attic fans have a price range from $ 75 to several hundred dollars at the highest level, a single installation of one of these units much cheaper than thousands of dollars, and most of the costs of disasters remediation of mold.
