Heat Recovery Ventilator for Radon Reduction

Occasionally, the diagnostic evaluation will indicate that a building requires a heat recovery ventilator to reduce the radon levels. A heat recovery ventilator (HRV), also called an air-to-air heat exchanger, is installed to increase ventilation, thereby reducing radon levels. A high performance HRV can provide comfortable, continuous, balanced ventilation for the entire home. As the HRV increases ventilation, it recycles the heated or cooled air that is exhausted to warm or cool the incoming air. HRVs can ventilate all or part of the building, but they are more effective for radon reduction when used to ventilate only the basement. Properly installed, balanced and maintained, HRVs can provide a constant amount of ventilation throughout the year.

One additional advantage of the HRV is that it also will exhaust stale air and other contaminants besides radon. The drawbacks are that it can significantly increase heating and cooling costs and it has difficulty reducing radon levels in excess of 12 - 15 pCi/l.
