Modern ventilation systems with heat recovery (HRV) use the heat contained in the exhaust air to preheat fresh outside air. This reduces heating energy demand, improves indoor air quality, and supports moisture protection and mold prevention. Learn how heat recovery works, the benefits it offers, and which types of buildings are best suited for this technology.
