how long can an electric dryer vent pipe be run
1. Measure the distance from the dryer to the nearest point on the house side or roof where you can install the vent cap. If it's more than 25 feet, you may have to relocate the dryer and its electrical outlet. That's the maximum recommended length of a dryer vent with no bends.Subtract 5 feet for each 90-degree and 2-1/2 feet for each 45-degree bend you need.very electric dryer has to have an outlet through which it expels warm, moist air, or it won't work. The air is usually loaded with lint, and if you don't vent it outside, it can cause all kinds of problems. The moisture can rot framing and promote mold growth, and the lint can catch fire.
