PDF Saving Energy with Electric Resistance Heating

Electric Resistance Heat Electric resistance heating converts nearly 100% of the energy in the electricity to heat. However, most electricity is pro-duced from oil, gas, or coal generators that convert only about 30% of the fuel's energy into electricity. Because of electric-ity's generation and transmission losses,
