WebElectrical Power Rating. Electrical components are given a “power rating” in watts that indicates the maximum rate at which the component converts the electrical power into other forms of energy such as heat, light or motion. For example, a 1/4W resistor, a 100W light bulb etc. Electrical devices convert one form of power into another. WebExample: A natural gas water heater with an EF of .58 and a fuel cost of $0.00000109/therm. 365 X .4105/.58 X $1.09 (the cost of natural gas on the Energy Label) = $282. For electric water heaters, including heat pump units. You need to know or convert the unit cost of electricity by kilowatt-hour (kWh).
