This is electric, but runs at 55 watts. It is a washer and dryer combination that holds up to 11 pounds of laundry. I tried weighing 11 pounds of laundry. Its surprisingly large. This unit will save space, which saves a lot of money in itself. I believe it will keep up with the laundry for a 3 person family just fine. The best part is, you put the wash in once, and when you come back, its done.
