Sep 12, 2013 · In most balanced ventilation systems, heat—and sometimes moisture—are exchanged between the two airstreams, reducing the heating and cooling loads caused by outside ventilation air. These systems are known as HRVs (heat recovery ventilators) and ERVs (energy or enthalpy recovery ventilators).

Mar 3, 2025 · Heat recovery ventilation (HRV) and energy recovery ventilation (ERV) (sometimes also called mechanical ventilation with heat recovery, or MVHR) offer a solution, bringing fresh air into your home without letting the heat escape. Let's take a closer look at how they work!

requires a principal ventilation system that exhausts air from bathrooms and kitchens, and supplies fresh air to bedrooms and living areas. One fan must continuously exhaust air at a minimum prescribed rate.
