couple thoughts the typical clothes dryer heats the air to 140-150f 60-65c. if its cold enough out that a greenhouse needs supplemental heating, then a solar thermal collector is unlikely to produce enough heat for a clothes dryer. i collect hotwarm air from under my roof for heating my house, but during the winter this air is typically only 20-30f warmer than the outside air
