The Energy Factor (EF) is the best measurement of a water heater’s overall energy efficiency. A higher EF means a more efficient water heater and energy cost savings for the homeowner. SeRIeS 102 100 SRMCA00107R May 2011 State Res Catalog.indd 11 5/27/11 4:48 PM.
Clarifies definition of “old”, “average”, and “new” vintage by eliminating gaps in range of year categories. The energy factor is used to calculate seasonal water heater efficiency. The energy factor is reported by manufacturers according to a standard test procedure.
