Heating Efficiency
As a heating technology, joule heating has a coefficient of performance of 1.0, meaning that every 1 watt of electrical power is converted to 1 watt of heat. However, a heat pump can have a coefficient of more than 1.0 since it also obtains heating energy from the environment. The definition of the efficiency of a heating process requires defining the boundaries of the system to be considered. When heating a building, the overall efficiency changes when considering heating effect per unit of electric energy delivered on the customer's side of the meter, compared to the efficiency considering the losses in the power plant.

Famous quotes containing the words heating and/or efficiency:
“If the factory people outside the colleges live under the discipline of narrow means, the people inside live under almost every other kind of discipline except that of narrow means—from the fruity austerities of learning, through the iron rations of English gentlemanhood, down to the modest disadvantages of occupying cold stone buildings without central heating and having to cross two or three quadrangles to take a bath.”
—Margaret Halsey (b. 1910)
“I’ll take fifty percent efficiency to get one hundred percent loyalty.”
—Samuel Goldwyn (1882–1974)
