Energy Efficiency Question

Hi. My sister recently moved and gave us her water dispenser. Could someone please tell me if this is an energy efficient model? The label details are this:
115V AC
60HZ
6AMPS

I think we need the name brand and the model number.

The name and brand isn’t on there. The model number says:
#F528HB010-NBWL (VBLX210EZ)

From what you’ve given us there is no way we can tell that the device is even a water dispenser! All you given us is the electrical requirement, and a company model number, not a model name. Model numbers don’t help unless you have the code book for a specific brand.
