1430 Records Efficiency and performance for ENERGY STAR certified water heaters may be evaluated using two different methods. The results of testing from these methods are not directly comparable. Solar water heater products have requirements for Solar Energy Factor (SEF), not Uniform Energy Factor (UEF).
A water heater's energy efficiency is determined by the energy factor (EF), which is based on the amount of hot water produced per unit of fuel consumed over a
Energy Guide. Resources Energy Guides are available for A. O. Smith water heaters at the Air-Conditioning, Heating and Refrigeration Institute (AHRI).
Products with the ENERGY STAR® label are the most energy efficient choices you can make as a consumer.
