I want to install a clothes dryer in a 110-year-old house. Can I use the now-unused (new direct-vent furnace last month!) furnace chimneystack to vent the dryer? The basement space with plumbing/electricity access is not adjacent to an outside wall. Or; can I vent through the wall into the now unused cistern. The cistern is underneath a shed addition added to the house probably 50 years ago or so. Thanks, Tony Pimm
