Heat Recovery Ventilation (HRV)
Advantages The cost is up to $2,000 for these units, The cost is up to $2,000 for these units, but the costs of running the ventilation can be offset by savings on heating and cooling in areas where ventilation is needed. Closely related are Heat Recovery Ventilators (HRVs) that, in addition, transfer also humidity between inbound and outbound stream.idity between inbound and outbound stream.  +
Characteristic features ERVs and HRVs can be stand-alone devices, or they can be added to existing HVAC systems  +
Description ERV is a system which provides controlled ERV is a system which provides controlled ventilation. This system is combined with a heat exchanger for reclaiming energy from exhaust airflows. By using the heated fresh air, less fuel is consumed in the boiler to achieve or maintain the desired operating temperature. These systems are closely related to the Heat Recovery Systems. However ERVs are not dehumidifier; they also transfer latent heat of the exhaust air. ERVs are also common in colder regions and for very tight houses with less than 0.5 air change per hour to provide adequate ventilation with already heated fresh air.ventilation with already heated fresh air.  +
