Venting a Dryer questions?

Hello everyone, I've made a post on here before about venting my electric dryer. When we bought the house, the dryer was vented up through the ceiling, through the garage attic space and through the roof and we had no problems ever until the ducts were cleaned. Thats when a drip started and a few years later ended up to the floor flooding and the flexline was filled with water and packed with lint.

I chose to buy an indoor vent kit eventually and installed a new bathroom fan that is 2x as powerful than needed for the space. This still hasnt worked as it makes the whole house have humid air and the walls are usually wet etc.

SO my question is how should I vent it outside, I do not like the thought of venting it through the attic space because if there is a problem again its inconvenient. The only other possible option to me is going through the garage which is on the other side of the laundry room, and then continuing to the exterior. It would require 15-20 feet of ducting and 3 elbows as there is limited ways to do it. The garage is also as cold as is it outside in the winter which is usually around freezing temperature.

Is that an acceptable distance of ducting and would I need to use insulated ducting or could i just heat up the garage with a heater. Keep in mind that I dont want to spend big bucks on this project, not because I'm cheap but because the house is for sale anyways so I dont want to put alot of money into something im getting rid of. Thanks!

 

You can go thru the garage. Three elbows is at max. for a vent system. We're only talking about a dryer here. Use metal duct work.... no flex piping.

 

my only concern is condensation forming on the duct work thats in the garage due to it being so cold in the winter months and having the same problem as before.

 

Use 4" medal ducting and only use flex to connect to dryer. Condensation should only be minimal as the heat from dryer will keep it dry when running and only happen the short time it cools. Dryer vents have been run through attics for years with no problems if you use solid tubing. I guess you had plastic flex before.

 

I don't want to go through the attic as its just more inconvenient and in my opinion would perform worse. The garage is not insulated anywhere not even the attic, so no matter where it is, its going to get condensation and thats what i want to avoid the most.

 

You could certainly insulate the 4" duct as it passes thru the garage.
