At the college I attended for grad school in historic preservation (Savannah College of Art & Design) I lived in the dorm for 1 hellish year. They had 5 gas dryers that all vented into 1 duct which was connected to 1 large vent to the outside. The problem was that if 1 or more of the dryers was not on at the time, the other dryers that were running would exhaust into the laundry room back through the inoperative dryers. The result would be a very hot and humid laundry room with the combustion exhaust from the gas burners. Many of the residents became ill from the combustion exhaust, and the lint and humidity also disturbed allergies and led to mold and mildew growth throughout the building's interior. I say to always vent dryers individually, especially gas dryers using metal ducting, not vinyl, and not the metal foil over a steel wire spring. Happy drying, Dave |

How does one install rigid metal ducting for a dryer, when the only access (practically speaking) to the rear of a dryer is by pulling it out from a wall? |

In a commercial laundromat where multple gas dryers exhaust into one much larger duct there are "check-vales" in the form of metal dampers on each machine that prevent above-described backflow. They dont always work well. Of course residential style machines don't have one. As a reminder, clothes dryers should NEVER be exhausted into the ductwork of any other type of appliance. Stove/cooker exhaust hood: GREASE and LINT combined is a big fire and safety hazard. Hot water heater/furncae boiler. JUST DON'T. The dryer will force posisonous gasses back into the living space by way of these appliances which add their own poisonous byproduct gasses. Bathroom exhaust fans: Can't run both a the same time due to excessive volume of air. In my opinion just install amother spearate vent. Relativley easiest and safest thing to do. |
