How Mechanical Ventilation with Heat Recovery Works

Air is extracted from rooms that typically produce heat, moisture and unwanted smells such as kitchens, utility rooms and bathrooms.
Before this air is expelled to the outside it passes through a heat exchanger. Where the heat is transferred to the incoming fresh air.
There by eliminating the need to completely heat the fresh air as it enters the building.
It is important to highlight that the stale exhaust air and clean fresh air do not mix in the heat exchanger.
The stale and the clean air are channeled through closely spaced, but separate, narrow sleeves in the core of the heat exchanger.
In order for the heat recovery to work properly, it is vital that the building is airtight.
