MVHR is Mechanical Ventilation Heat Recovery. Having created an airtight building to prevent heat loss, it is equally important to ensure a controlled air flow remains within the building to prevent the air becoming stale or humid.

MVHR Systems are designed to deliver fresh air throughout the building in a controlled manner. The system uses the heat from the exiting environment to heat the incoming fresh air. This not only provides ventilation but also filters out dust particles and balances humidity levels.
