    I am installing a gas dryer and would like to know if I can vent it down through the floor and out a basement window. Any ideas?

    Thanks for any replies

    Not sure about codes, but you'd have a big problem if there was a leak, plus, I think you'd end up decreasing the efficiency by maybe a significant amount...hot air wants to rise, not be pushed down. Plus, if there was a leak, you could have CO, too. Having it rise, like in a flue, is both safer and more efficient.

    This would be in a flu pipe (rigid) but it would go downwards about 2 feet and over about 5' before exiting.

    Thanks for any replies

    Actually, I don't see a code issue with dropping down and over. True that heat rises, but air has mass, and can be pumped down more easily than up. Efficiency will not be affected.

    Just exactly how you terminate needs to be worked out. You don't want moist air backfeeding into the basement through that window, or collecting in a poorly ventilated space.

    If this will work. I will probably eliminate the small basement window entirely to terminate the vent through.

    You bought a dryer window?
    This must have been after the 3rd wisdom tooth was removed ;)
    My house they just cut the glass & put the vent in

    I'll let you know that that dryer vent window has been tested.

    Yes but mine has bubble wrap :D
    The bubble wrap window is now inside the garage
    I'd like to sya they cut the window glass & put in a piece of wood
    But in reality they just broke the window glass & put up a small piece of paneling :mad:
    The whole area will be cut out for a door to the garage


    They used to have the sump pump output going out this window too
    I moved it to the back window that is a storage area under the sunroom
    It then enters a drainage pipe that goes out past the garage

    The dryer will move to the right of the window & go out thru the rim joist
    Then a short jog to the right to exit the garage

    Agreed...but Daves does have that Down Home Kentucky "I live back in the Holler" look with the bubble wrap....

    Just kinda gives you that warm feeling...

    Sorry Runs with Bison. But mine is shiny copper. I ripped the stock one out and whacked a copper one in!

    Now, I must dash to brasso all my pipes.

    Really ? You put a copper dryer vent in?
    I've never even seen one, we want a pic !!

    Since I was building the garage I saw no point in trying to fix something that was being cut out for a door
    5 single PAIN windows in the basement & all of them were either not sealed at all or (3) had broken panes

    The new garage/Great Room I built sort of blocks the old vent
    (Ian calls this a 3 family Apt building I think)

    Yes, note how Scuba Dave bought a small house and then whacked that massive thing on the side of it.

    Kind of like a Prius pulling a 53 foot semi.

    The "Great Room"....

    T'was carefully planned so as not to be seen driving down the street (most of the time)
    It's not til you come up even with the house that it "appears"

    The rest of your house looks a lot like mine. Minus the American flag of course.
