Venting dryer thru vacant roof furnace duct

feethSeptember 12, 2011

I have a vacant furnace vent. (furnace now vents another way)

My dryer vents into garage right now. Going to run new metal 4" ducting up into attic, install Fantech DBF 110 Dryer Booster Kit inline. Will also have another lint trap in the wall.

Was thinking of venting it out thru the soffit, but can I use the vacant furnace vent that goes thru the roof?

TIA!

Never vent through the soffit.

Your proposed method seems to entail condensation problems.

Best dryer venting is short and smooth.

Can you do it? Probably. Insulated ducting MIGHT solve condensation trouble.

My attic only gets max temp of 93 thanks to foam insulation, so would not that combined w/ the dryer booster fan reduce condensation?

Any thoughts on the vacant furnace vent?

It sounds good in theory, but I would not do it. Those dryer vents need a good cleaning out from time to time, and it's easier to push the lint out from inside the house. In a furnace vent, you'd have to push it up, or pull it up, or vacuum it out somehow.

"Any thoughts on the vacant furnace vent?"

As stated earlier, you can probably do it. There is a nagging doubt in the back of my mind about some tin badge home inspector causing trouble down the road (say, resale).
You'll have to remember to clean the lint trap(s). Seems easy to forget.
Since you're running a booster there is also the potential of de-pressurizing your house, something you need to consider inre: heating/cooling, combustion draft etc.

Lower temps INCREASE the chance of condensation by cooling the warm dryer air.
