90–95% (multiply by the energy efficiency of electricity generation to compare with other water-heating systems) Electric heater: Electrical to thermal ~100% (essentially all energy is converted into heat, multiply by the energy efficiency of electricity generation to compare with other heating systems) Others: Firearm: Chemical to kinetic
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 ...
A counter flow heat exchanger is the most efficient type of heat exchanger in transferring heat energy from one circuit to the other [citation needed]. However, for a more complete picture of heat exchanger efficiency, exergetic considerations must be taken into account. Thermal efficiencies of an internal combustion engine are typically higher ...
Alternatively, a heat pump can achieve around 150% – 600% efficiency for heating, or COP 1.5 - 6.0 Coefficient of performance, because it uses electric power only for transferring existing thermal energy. The heat pump uses an electric motor to drive a reversed refrigeration cycle, that draws heat energy from an external source such as the ...
The first Cub Cadet model made was the International Cub Cadet Tractor, better known as the Original. The Cub Cadet Original was powered by a 7 hp and 8 hp replacement Kohler engine and was made between 1961 and 1963. The CJR was a hydrostatic version of the Cub Cadet transmission made by Sundstrand Corporation.
Although the General Services Administration had Specification W-H-193 [13] for electric space heaters, it was replaced in 1995 by the UL standards. Additional information on portable-heater safety may be found at the Department of Energy's Energy Efficiency website. [14]
