What effect does heat loss through the vent have on its performance?

Heat loss through a vent can reduce the air temperature and, subsequently, the pressure inside the vent system. When warm air escapes due to heat loss, it can lead to a decrease in static pressure, making it harder for the ventilation system to function effectively. Lower static pressure means that the system may not be able to overcome the resistance of the ductwork and deliver the required airflow. This diminished performance can compromise the overall efficiency of the ventilation system, resulting in inadequate air exchange and potentially impacting the comfort and safety of the environment being ventilated.
