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. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   The thermal efficiency of modern steam turbine plants with reheat cycles can reach 47%, and in combined cycle plants, in which a steam turbine is powered by exhaust heat from a gas turbine, it can approach 60%. [4] Brayton cycle: gas turbines and jet engines The Brayton cycle is the cycle used in gas turbines and jet engines. It consists of a ...

4. Annual fuel utilization efficiency - Wikipedia

   But for an instantaneous fuel consumption rate, the thermal efficiency may be better. The theoretical limit for a conventional furnace's instantaneous efficiency is 100%, whereas a heat pump used for building heating may exceed 100%. For example, a COP of 1.5 is equivalent to 150%. Heat pumps are readily available for electric and gas sources. [3]

   This factor has led to an Energy Star rating for its high efficiency. This type of horizontal-axis washer and dryer (with a circular drum) is often used in Europe, where space is limited, as they can be as thin as 41 cm (16 in) in width. [82] In 1998, New Zealand-based company Fisher & Paykel introduced its SmartDrive washing machine line in ...
