Cop of electric resistance heating
WebApr 12, 2024 · Heating is associated with loss in electric circuits. Imagine current passing through a resistor and the body of the resistor heating up. The heat generated is the loss of energy and is usually called heating loss or I2Rt loss. With Joule's law of electric heating equation, we can determine the Joule equivalent of electrical energy. WebFeb 2, 2015 · A heat pump may have a COP of 1.5 to 4.0, meaning it operates at 1.5 to four times the efficiency of electric-resistance heat. A heat pump operates at this efficiency because it uses a compressor and refrigerant to move heat from one space to another, instead of generating heat.
