How to vent an electric dryer when outdoors isn’t option

venting

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

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.
