A module adapted to generate a stream of hot, humid air includes a housing, a chamber disposed within the housing and having an air intake and an exhaust vent, and a reservoir adapted to hold a volume of water. A blower is disposed adjacent the air intake and is adapted to propel a stream of air through an interior of the chamber toward the exhaust vent. A steam generator is disposed substantially within the interior of the chamber and has a water inlet in flow communication with the reservoir and a steam outlet in flow communication with the interior of the chamber. A first heater is disposed on an external surface of the steam generator and a second heater is disposed within the interior of the chamber.
