- Energy Factor (EF): Energy Factor is an older testing measurement. It is used by the Department of Energy to determine overall energy efficiency.
- First Hour Rating (FHR): An estimate of the maximum volume of hot water in gallons that a storage water heater can supply within an hour that begins with the water heater fully heated. Based on an outlet temperature of 125° F for the Uniform Energy Factor test method and 135° F for the Energy Factor test method.
- Gallons per Minute (GPM): The number of gallons per minute of hot water that can be supplied by an instantaneous water heater while maintaining a nominal temperature rise during steady-state operation.
- Solar Energy Factor (SEF): The energy delivered by the total system divided by the electrical or gas energy put into the system.
- Uniform Energy Factor (UEF): Finally, the newest measure of water heater overall efficiency. The higher the UEF value is, the more efficient the water heater
