Energy- & Heat-Recovery Ventilators
Available14 products
Energy-recovery ventilators (ERVs) and heat-recovery ventilators (HRVs) refresh and condition the air in indoor spaces. They help reduce utility costs by using the air that is being vented out of the space to condition the fresh air that is being brought into the space. Also known as balanced ventilation, this process replenishes oxygen and reduces airborne contaminants in indoor air to help occupants breathe more comfortably.
Residential Energy-Recovery Ventilators
Residential ERVs plug into an outlet and do not need to be hardwired into a home's electrical system, which reduces installation costs. They also draw less energy than commercial ERVs. ERVs transfer some of the heat and humidity from the outgoing air to the incoming air in the colder months, which reduces demand on the home's heating and humidification equipment in areas that have dry winters. They also remove some humidity from the incoming air in the warmer months, which reduces demand on the home's air-conditioning or dehumidification equipment in areas that have moderately humid summers.

Commercial Energy-Recovery Ventilators
Commercial ERVs have a higher maximum airflow rate than residential ERVs, making them suitable for offices and other large commercial spaces. These units are hardwired into a building's electrical system. ERVs transfer some of the heat and humidity from the outgoing air to the incoming air in the colder months, which reduces demand on the building's heating and humidification equipment in areas that have dry winters. They also remove some humidity from the incoming air in the warmer months, which reduces demand on the building's air-conditioning or dehumidification equipment in areas that have moderately humid summers.

Residential Heat-Recovery Ventilators
Residential HRVs plug into an outlet and do not need to be hardwired into a home's electrical system, which reduces installation costs. They are suitable for homes in areas with moderate humidity in the winter. HRVs transfer some heat from the outgoing air to the incoming air, which warms and dries out the incoming air and reduces demand on the building's heating and dehumidification equipment.
