2. Energy factor - Wikipedia

   en.wikipedia.org/wiki/Energy_factor

   The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...

3. European Union energy label - Wikipedia

   en.wikipedia.org/wiki/European_Union_energy_label

   A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles. For the washing cycles, a weighted ...

   Almost all of its standards are joint standards with Australia. New Zealand has mandatory Energy rating labelling for dishwashers and clothes dryers, fridges, washing machines and room air conditioners. MEPS apply to the following: [6] Refrigerators and freezers; Washing machines; Air conditioners; Computer room air conditioners; Chillers

7. Washing machine - Wikipedia

   en.wikipedia.org/wiki/Washing_machine

   The EU requires that washing machines carry an efficiency label. Washing machines display an EU Energy Label with grades for energy efficiency, washing performance, and spin efficiency. Grades for energy efficiency run from A+++ to D (best to worst), providing a simple method for judging running costs.
