I want to install a clothes dryer in our laundry. Unfortunately it has sandstone walls 40 cm thick and so installing a venting system to the outside is going to be very difficult. I was wondering if there was a way around this so that I could vent the system into a nearby sink (whether there is a way to re-condense the air as it comes out so that it ends up as water again or alternatively whether the vent could be passed through a body of water (so that the moisture in the air would be trapped in the water).
Any suggestions?
