A Heat Recovery Ventilator (HRV) is a mechanical ventilation device that helps make your home healthier, cleaner and more comfortable by continuously replacing stale indoor air with fresh outdoor air.
HRVs are set apart from other mechanical ventilation devices by their ability to exchange heat between the supply and exhaust air streams, which in turn reduces the cost of heating or cooling the healthy fresh air that circulates through the home.
HRVs are sometimes called air-to-air heat exchangers because they preheat or cool incoming air using exhaust air.
How a Heat Recovery Ventilator Works
1. Warm, stale air is drawn from the kitchen and bathrooms
3. Fresh, heated air is sent to bedrooms and living areas
2. Fresh, cold air from outside is drawn in
4. Stale, cool air from inside is exhausted outside
