WebFan Heat Gain: All electrical energy used by a supply air fan eventually ends up heating the air around the motor, at the fan, within the ducts, at the diffuser, and within the spaces to which the air is supplied. When the airflow dissipates within the receiving spaces, 100% of the energy put into the fan will have become heat somewhere along the way.
