Ventilation

ERV

Balanced ventilation in warmer climates that brings fresh air into the home while retaining up to 60% of the energy value of the exhaust air, and rejecting about 40% of the moisture in the fresh air stream, when compared to mechanical ventilation products with no heat or energy recovery.

HRV

Balanced ventilation in colder climates that brings fresh air into the home while retaining up to 60% of the energy value of the exhaust air, compared to mechanical ventilation products with no heat recovery.
