What is a heat recovery ventilator (HRV)?
These units replace the air being exhausted from your home such as by bathroom fans and kitchen exhausts, with fresh outdoor air that has been pre-conditioned, through an internal heat exchanger. This saves a significant amount of your energy dollars since you don’t have to heat and cool the outdoor make up air as much. In addition, these special heat exchangers do not cross contaminate the air with whatever is being exhausted. These units can also significantly reduce the drafts in your home since the air being exhausted from your home is being replaced with treated air and not being sucked in under doors, through cracks in your home, such as plumbing holes that allow air from under your home to enter your home, or window leaks.
