Oct 29, 2015 · Heat Recovery Ventilators (HRVs) are an essential component of any air-sealed high performance home, bringing in fresh air and removing moisture. An HRV uses the heat in stale exhaust air to warm incoming fresh air. Until now, this has meant a centralized heat transfer core and a network of ducts feeding and drawing air throughout the home.
HRVs and ERVs provide fresh air while also saving energy by reducing heating and cooling requirements. HRVs remove and add humidity to the air as needed, providing improved climate control. While ERVs function similarly, they do transfer the humidity level of the outside air to the interior space. Grainger offers a wide range of heat recovery ventilator and energy recover ventilator options Heat and energy recovery ventilators - NRCanA heat recovery ventilator (HRV) is a ventilation device that helps make your home healthier, cleaner, and more comfortable by continuously replacing stale indoor air with fresh outdoor air. New homes built since 1977 are more airtight, which helps save energy but can make the inside air stale.
Energy Recovery Ventilators (ERV) transfer heat/cooling energy and water vapor, helping to balance humidity in the cooling season. ERV and HRV circulate fresh air throughout the home, while recovering heating and cooling energy. You no longer have to open windows and doors, keeping your heated or cooled where its meant to beinside your home.
