A heat recovery ventilator system (also known as an HRV) is perfect for homes that are located in colder climates since this unit gets rid of any of the excess moisture during the heating process.
This system supplies a constant flow of fresh air from outside of the home. The heat recovery core inside the unit transfers a part of heat in the stale air. It is then exhausted to the fresh air coming inward from the outside, before being spread throughout the entire home. The end result is a continuous amount of fresh air with no unpleasant drafts of any sort. This increases the comfort to maximum for any and all occupants of the home.
