We have a building on the 3rd floor of a 4 floor building that we are building a loft in, It is in an historic area, we are in the middle of the block downtown. size 21'wide x 180'long, left and right walls are 18" of brick with plaster overlay. venting through the roof isn't an option. do they make a ul rated dryer lint box or can a vented electric dryer be vented to a converter of sorts to stay in code for indoors. I am at a cross roads I have a brand new electric washer and dryer I bought a year ago. I cannot take it back and I am trying to find a way to complete this project so the building inspector will let us move in. Do you have any info or options. Thanks so much

    Do you have a water and electric hook up for these?? – JACK Nov 6 '19 at 23:20

The proper answer for this, and certainly the one the building was built for, is to use a condensing dryer. This is a special dryer with a dehumidifier built in, which then overboards the recovered moisture into the drain intended for the washer.

I suppose you could do the same thing with an actual dehumdifier. If you can find a way to install it above the washer drain, almost any model will let you route a hose from its output, so the bucket never fills up. Some dehumidifiers also have a water pump to push the drain water uphill if needed.

    You can even get condensing dryers which capture the water and thus don’t need drain access. – Moo Nov 7 '19 at 4:47

Although 18" of brick would be difficult to drill thru, it can be done. Check your local listings for a company which cuts/drills concrete. I have had a local company drill thru 12" of concrete block with 6" of natural stone veneer. With the proper bits and drills, it should be doable for a pro; however, it will NOT be cheap. My 4" hole cost me $300, but it was money well spent. Trying to chisel and break thru would have been near impossible and would have looked terrible. Good luck!

You can use a lint trap/condensing box if you want to.

It is messy, and doesn't work particularly well, and you'll wind up heating up your apartment in the summer, but it does work.

I used one for 8+ years.

Condensing dryers work much better.

My dryer originally vented indoors, which was OK (except for the lint) in winter and horrible in the summer. I moved the dryer in order to be able to vent it out through a window. I cut a piece of plywood to replace a section of the window and cut a hole in that for the vent.

Obviously if there is no window in that room then it gets a little harder to do this, but according to this web site on dryer vent safety, you can potentially go as far as 35 feet.
