The amount of heat, rated in BTUs that the item can produce.

The percentage of energy converted into output by the unit. The remaining percentage is lost during the conversion process. The higher the efficiency, the lower the operational cost.

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

• Product categories must contribute significant energy savings nationwide.
• Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
• If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
• Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
• Product energy consumption and performance can be measured and verified with testing.
• Labeling would effectively differentiate products and be visible for purchasers.

The noise produced by the unit rated in decibels. 30dbs is equivalent to a whisper, 60dbs is equivalent to a normal conversation, 90 dbs is equivalent to a lawn mower.
