What is COP (Coefficient Of Performance)?
The coefficient of performance (COP) is a measure of a heat pump’s efficiency. It has become common industry practice to use the term COP when expressing efficiency for heat pumps. It is determined by dividing the energy output of the heat pump by the electrical energy needed to run the heat pump, at a specific temperature, typically at 7 degrees C. The higher the COP, the more efficient the heat pump. The Energy Saver delivers a class leading COP of 4.2.
