My husband and I bumped out into the garage to create a main floor laundry room. The connections are set in the wall between the laundry room and the garage. We aren't sure how to vent the dryer -- go up and through the roof or wrap a vent pipe around the exterior wall of the laundry room and out through the exterior wall of the garage. If we were to do the latter, we would need to make two 45 degree bends and the total length of the vent pipe would be about 20 feet. Which way is better? Or is there another solution? I should mention this is an electric dryer, and we live in Minnesota, so the temperature range is wide and we have humidity.
