Keeping your home cool in the summer and warm in the winter is one of the big goals of most homeowners. There are a number of ways to do this, including upgrading the windows to more energy-efficient models and performing seasonal maintenance on heating and cooling systems to keep them operating at peak condition. One thing that’s often overlooked however is the influence that attic temperatures can have on the temperature of your whole house.
You may have seen suggestions about installing automatic attic vents to help regulate the temperature in your attic. Is there something behind this, or is it just another upgrade to your home that provides very little benefit? You might be surprised at how effective automatic attic vents can be.
Hot Attic, Cold Attic
It’s pretty common knowledge that hot air rises. The question is, where does all that hot air go? If your attic isn’t well vented, it can build up within the attic itself and increase the temperature of your attic space significantly. The problem with this is that future hot air won’t really have anywhere to go, causing it to linger in the house itself for longer. This is great if it’s the middle of winter and you’re trying to keep your house warm, but you can see how it might be a problem during the heat of summer.
You can run into the opposite situation as well if you have open vents in the attic. Heat can escape more easily, but if it’s cold outside you’ll find all that heat escaping much faster than you would like. This, in turn, causes heat within your house to escape faster, making it harder to stay warm in the depth of winter’s chill.
Regardless of the situation you find yourself in, the end result will be the same: higher energy costs to keep your house cool in the summer or warm in the winter.
Proper Attic Venting
Attic ventilation is part of the key to solving this issue, but there isn’t a one-size-fits-all solution. During the summer, you want open attic vents to expel heat and keep your attic as cool as possible. In winter, you want attic vents to be closed to hold heat in for as long as possible. You can open and close these vents manually as part of your seasonal preparations, of course, though this won’t be a perfect solution. The truth is, unless you open or close the vents to account for all the temperature fluctuations during the year, you’ll still be losing money to unnecessary heating and cooling.
Automatic Attic Vents
This is where automatic attic vents come into play. These vents are connected to thermostats (and sometimes even humidistats) to monitor the condition of your attic and open or close the vents as needed based on what things are actually like in the attic. If the temperature goes too high during the summer or if it becomes too humid, the vent opens and lets that unwanted heat and humidity escape. If temperatures drop, the vents close to prevent outside heat from coming in. The opposite happens during the winter, keeping the vents shut to keep warm air in your attic.
Some automatic vents function as simple ventilation units, possessing little function beyond opening and closing. Others include connected fans to force air in or out of the attic to even greater effect. Regardless of the vent type, you choose, however, adding one to your attic can make a notable difference in how warm or cool the attic air gets during the year.
