Another comment from my colleagues at IRC:

When I want BOTH heat and humidity, I disconnect the dryer outlet hose at
the outdoor vent, and redirect the hose indoors.  I use a leg of my wife's
used pantyhose  attached to the dryer hose outlet to catch the lint.,
cleaning it out between dryer loads.  Finally, I block off the outdoor vent
to limit infiltration of cold outdoor air. If I wanted the heat but not the
humidity, I would insert a small heat exchanger in the dryer outlet and
continue to vent to the outdoors.  The heated air recovered from the heat
exchanger could be simply returned to the indoors, or directed to the cold
air return of my forced air furnance to distribute the reclaimed heat
throughout the house.  I wouldn't spend a lot of $$$ on the heat exchanger,
however, because I doubt it would recover enough heat to make it cost
effective.  I'd probably try a homemade device.  Wouldn't be as efficient,
but then it couldn't hurt, and there'd be nothing to lose.  Note that I
would NOT connect the dryer exhaust directly to the cold air return of my
heating system for fear of reducing the efficiency of my combustion furnance
(due to the moisture), and fear of accellerating corrosion within the
furnance and plenums.  If you hear of any other comments, please let me
know.
