Venting a dryer in a chimney
A few weeks back, I was reading DIYChatroom and saw your sig (Not the first time) just as an ad for the Lint Lizard came on the TV. I walked to the laundry room and checked the vent (not the first time for that, either). To make a long story short, 4 (6?) hours later I had replaced the plastic vent hose with a metal periscope, relocated the surface mounted 220V receptacle, and cleaned the lint from the dryer interior and the vent hood. The dryer sounds different and dries a load of clothes about 25% faster.
