An ERV can reduce the energy required to condition outdoor ventilation air by recovering part of the heat and, where applicable, moisture from the exhaust air.
Actual savings depend on climate, airflow, recovery efficiency under operating conditions, fan power, duct resistance, operating schedules, and the performance of the heating and cooling system.
For a meaningful comparison, evaluate both recovery performance and the electricity consumed by the fans.
