A heat pump has a cop rating of 2.5 to 1 if 200 watts of electricity are used to run the heat pump how many equivalent watts are produced?
Since the Coefficient of Performance (COP) is 2.5, for every 1 watt of electricity input, the heat pump produces 2.5 watts of heating or cooling output. Therefore, if 200 watts of electricity are used, the heat pump would produce 2.5 times 200, which equals 500 watts of equivalent heat output.
