Heat Recovery and Energy Recovery Ventilators
To protect the health of your family, your home, or your building, improving indoor air quality is
key. Heat Recovery Ventilators (HRVs) or Energy Recovery Ventilators (ERVs) solve ventilation
problems by moderating extremes in ventilation temperature and in humidity. They improve
indoor air quality and lessen the load on air handling units for a more efcient system. Stale
room air is exhausted and fresh outdoor air is brought back into the structure. The airstreams
are physically separated so there is no mixing or contamination of the fresh air.
HRVs and ERVs both:
• Reduce energy consumption while providing fresh
air when heating or cooling
• Moderate extremes in ventilation temperature
• Use heat that would otherwise be lost with the
exhaust air in the winter.
• Provide necessary fresh air while pre-cooling in
summer
• Meet ventilation codes and standards.
