Air is vital to all living things, and although a dryer isn't alive, it too needs air in order to do its job of drying laundry in the most efficient and productive manner possible. Air is the most important aspect of the drying process. Without it, a dryer won't function correctly.
Clothes dryers are not air-tight, and if a blockage in the vent occurs, the hot, damp air that would ordinarily safely blow out is instead trapped inside the drum, leaking slowly around the door and any other small exit points in the dryer body.
Unfortunately, your dryer creates carbon monoxide as part of the drying process. Your dryer can leak carbon monoxide into your home if the vents are not maintained or installed correctly.
Is it harmful to breathe warm air from an electric dryer vent? A whiff or two in passing should be ok from time to time. However, it is something you don't want to be exposed to long term or even every day. It is mainly air at about 100% humidity, which is OK.
Never leave a dryer running when you're away from home, and never leave it running while you're sleeping.
Typically, a gas or electric dryer should take about 30 to 45 minutes to dry a full load of clothes. Dense fabrics—like a quilt or a load of thick bath towels—may take up to an hour to dry.
To operate correctly, dryers need vents that allow heat, lint, and moisture to be expelled outdoors. Dryer vents assist in creating a suction force that removes lint from clothes and allows air to circulate more effectively.
Carbon emissions from your washer and dryer can vary a lot – from 51 to 159 kg CO2 each year. On average, each load of laundry washed in hot water and tumbled dry releases 3.3 kg of carbon dioxide. The dryer is the biggest culprit, making up almost 6% of home energy use.
While dryer lint may be an effective fire starter, it is not a safe one and should never be used to start a fire in your fireplace. Dryer lint contains toxic chemicals that release when burned and can put your family and your home at risk.
More specifically, electric dryers are shown to be more than 2.5 times more likely than gas dryers to cause fires due to the higher heat discharge from electric dryers which increases the problem of lint buildup. Dryer fires typically originate from two places, dryer venting and the lint trap.
Cons of Clothes Dryers
Clothes dryers also put a lot of wear and tear on your clothes, as mentioned above. With some models, you might see your clothes start to fade or degenerate. With some fabrics, you should never use a dryer. Make sure when you read the label that tumble dry is an option.
This is a big concern with heating systems that burn gas or oil. If your dryer exhaust isn't pushing the air outside when it's finished with it, then the CO2 can buildup inside your home. This can lead to sickness, headaches, and in extreme cases even death.
Some garments dry up better in a machine.
"There are certain items that do not fair well with air-drying," he explains. "Many heavy sweatshirts and sweatpants, as well as towels, are better off in the dryer." Lighter pieces like linen items, on the other hand, dry nicely on a line.
As high heat and tumbling action suck away moisture, fabric fibers pull together tightly and curl up in response, resulting in clothes that no longer fit. Your clothes will last longer. Air-drying is much gentler on your garments than a dryer.
Tumble dryers generate even more microfiber pollution than washing machines, a new study suggests. A lot of these microfibers—tiny textile strands that can pose a threat to environmental and human health—get trapped on dryer lint filters.
If you open your dryer early in the cycle and smell gas or can smell it on your clothes, that's a sign that your igniter is going bad. This ventilation issue can be caused by a dirty filter or an exhaust system breach.
Air Circulation
The air is sucked into the dryer through openings in the outside of the machine. One fan drives all of the air through the dryer, but the fan is actually the last step in the process.
Air Flow (vent to the outside) is Important
In order for the clothes to dry, this moisture has to exit the dryer to complete the drying process. If the moisture is not vented and allowed to leave the dryer in some way, dry times could be extended dramatically.
In some places in Europe, such as Switzerland, vented dryers are illegal because of their environmental impact.
Instead of venting that hot, wet air outside, the air is looped back into the condenser where it's cooled down—that's the second airflow loop. From there, the air that's already inside the condenser is reheated and sent back into the drum to repeat the process until the clothes are dry.
Unfortunately, ANY amount of heat is damaging to hair, so using a blow dryer (or flat iron, or curling wand) every day is a bad idea. Daily heat exposure can ruin hair by stripping the hair's natural oils, drying out the cuticle and causing breakage and frizz.
How long should a dryer take to dry? A typical drying cycle takes about 45 minutes, but this time can vary depending on the cycle, heat setting and size of your load. Delicate cycles take roughly 15 minutes, while heavy cycles, like bedding, can take up to three hours to fully dry.
Generally, it takes about 30 to 40 minutes to dry an average load of laundry on a medium setting.
