How Heat Recovery Works

Heat recovery ventilators contain two fans. One extracts the air from the room and the other replaces it with fresh air. The two air flows pass through alternate layers of a highly efficient heat exchanger. The heat in the extracted air is passed to the incoming cooler air, but air streams do not mix within the ventilator.

These ventilators are designed to run continuously at low speed providing background ventilation. When the humidity exceeds a pre-set level the ventilator switches to boost, rapidly removing the damp stale air.
