So each clothes dryer appliance has an exit port. You connect a hose to it to vent the damp air to the outside.
I want all dryers to have an intake port so that I can use cold air from the outside for drying. This will keep me from using (expensive) warm air from the inside of my house.
I suspect this will also make the dryer more efficient because the cold incoming air could contain less humidity.
That’s interesting technology. 'Will seriously consider this when replacing this gas dryer. It only gets used for smalls (we use a clothes line for everything else) so is still in good shape after many years. We’re reducing the amount of gas we use so it’s going to be replaced at some point because of that.
