In today's houses, dryer vents tend to be vented longer spaces, making more places for lint to combine. Even though dryers are equipped with lint traps, a considerable amount of lint is not caught by the trap, and instead, increases inside the dryer. Moreover creating a fire danger, if your dryer vent duct is too long or has too many wraps, it will cause your dryer to take much more than necessary to dry loads, using wasted energy and electricity. Eventually, inappropriate clearance extent between the dryer and the wall can make the dryer work inefficiently. Many people make problems by putting their dryer verses the wall smashing the venting material in the process. The accumulative effect of reduced air-flow and the resulting lint buildup prohibit the dryer from drying at an ordinary rate and risk causing a fire.
