Heat Recovery Ventilation

A Heat Recovery Ventilation (HRV) system is designed to ensure optimum air exchange in a building while minimizing heat losses through ventilation. In traditional family houses where ventilation is ensured through trickle vent or slot vent, heat losses through ventilation represent up to 40% of the building’s total heat loss.
