ENERGY STAR® Qualified Office Equipment

Water Coolers

A standard hot and cold water cooler can use more energy than a large refrigerator. An ENERGY STAR qualified model requires about half as much energy as a standard unit and provides:

  • Improved separation of hot and cold water to prevent mixing.
  • More insulation to better keep heated water hot and chilled water cold.
  • Improved chilling mechanisms.


Energy Star High Efficiency Logo To be ENERGY STAR qualified dispensers of cold water or both cold and room temperature water must have standby energy consumption of no more than 0.16 kWh/day. Dispensers of both hot and cold water must have a standby energy consumption of less than or equal to 1.20 kWh/day. (Standby energy consumption refers to the energy required to maintain the water at an appropriate dispensing temperature.)

Purchasing or Leasing Tips

For the Home or Small Office:

Water coolers are sold at retail stores and also through some water distributors. If you are purchasing from a store or off the web, look for the ENERGY STAR on the box or the unit itself. If buying or leasing from a water distributor, tell the distributor that you want an ENERGY STAR qualified model.

For Commercial Use:

When requesting bids for water service that include provision of water coolers, clearly state a preference for ENERGY STAR qualified models in the request for bids.
