In one aspect, a cab heating system for an electric work vehicle includes a hydraulic circuit forming a hydraulic flow loop through which a hydraulic fluid is directed for supply to a hydraulic component of the electric work vehicle. The system also includes a coolant circuit forming a coolant flow loop through which a coolant fluid is circulated, with the coolant circuit comprising a coolant heat exchanger. Additionally, the system includes a circuit heat exchanger thermally coupling the hydraulic circuit to the coolant circuit to allow heat to be transferred between the hydraulic fluid and the coolant fluid, and a fan configured to direct an airflow across the coolant heat exchanger such that heat is transferred from the coolant fluid to the airflow prior to delivery of the airflow into an interior of a cab of the electric work vehicle.
