Water Source Heat Pump Efficiency

What is the definition of a water source heat pump efficiency? Water source heat pump efficiency is the measure of how much energy is used to heat a space compared to the amount of energy that has to be inputted to the system to provide such heat. In a nutshell, it is the ratio between energy used and energy inputted. This ratio is known as the coefficient of performance (COP). The higher the COP, the more efficient the system is. A COP of 6 or higher is considered to be highly efficient. In order to calculate the COP, you need to know the energy input to the system, the energy output to the space, the temperature of the air entering the system, and the temperature of the air leaving the system. The COP can be calculated by dividing the energy output by energy input. With water source heat pumps, the water serves as a medium to transfer the heat from outside the building into the space. This process is known as geothermal heat exchange. Water source
