WarmlyYours electric towel warmers require no more power than is generated from your standard 120V wall outlet. For hardwired towel warmers, all the wiring is done through the wall. A separate power source is not required; power can be pulled from the nearest available source. For plug-in towel warmers, all that is required for electric hookup is that the unit is plugged into a properly grounded outlet located within 6 feet (1.8m) of the unit.
