My older Brother w/diabetes is able to live in our "Cottage" (2 rooms at 15 x 15 each) which is needing many repairs but with the ceiling, floor, and walls shored up is able to maintain a 78-degree temp with an ambient temp 97 degrees.  Drainage is about every 8-12 days.  Would like a better design to drain the machine but both condensation and humidifier do work and are drainable. Open up both stops and tilt the machine. Overall very pleased.
