HEAT RECOVERY VENTILATORS

The primary purpose of a Heat Recovery Ventilator (HRV) is to replace stale inside air with fresh outside air. The HRV is designed to actually heat the cold incoming air thereby improving the overall cost effectiveness of the ventilation strategy.

The HRV greatly contributes to the overall effectiveness of your home's comfort performance. It also greatly improves the indoor environment which no doubt results in a healthier family.
