When our dryer was replaced we decided to bring the dryer venting system early 1960 up to code by replacing the tubing that vented into the attic.
Venting electric dryer into attic.
Venting the dryer outside in cold weather wastes a lot of heat.
Every electric dryer has to have an outlet through which it expels warm moist air or it won t work.
That is the old material type tubing simply ended by a overhang side of the house where it exhaused into the attic and not outside.
Dryer lint is also highly flammable.
The air is usually loaded with lint and if you don t vent it outside it can cause all kinds.
The attic is usually colder than the rest of the house during the winter and that can create a problem for a dryer vent.
You can buy a box called an indoor dryer vent kit at home improvement stores and it manages to control most of the lint but not the water dumped into the air.
A dryer vent should be vented outside.
Not all dryers will allow for this so be sure to check the owners manual to ensure it can be vented in this manner.
When a dryer is in.
Some homeowners use a much simpler system of venting down into a bucket of water like in the photo at the top of this page.
But we don t recommend it for two reasons.
In these cases it may be necessary to vent your dryer through the attic.
For dryers that are located in a place where venting to the outside is difficult it s ok to simply vent the dryer into a container of water.
