Wall vents serve no purpose in a building heated with
electricity. They are largely a relic from the times heating by combustion inside the
room was common (wood or gas heaters) and ensured some ventilation. Unfortunately
wall vents are located near the ceiling, where the warmest air accumulates
and the vents serve as chimneys for heat to escape into the wall and ceiling
cavity.
