Has anyone had experience with air to air heat exchangers used for radon mitigation in a residential application, specifically configuration of ductwork.?

ER/HR ventilators & radon
Radon infiltration can be mitigated in many ways, one of which is to keep the basement under a slight positive pressure, and the most economical way to do that is with an energy or heat recovery ventilator. It would be on seperate ductwork fron the heating & AC system, sealed tightly, and would bring in slightly more air than it exhausts. Often, an adjustable damper regulates air flow, and the ER/HR unit runs 24/7 on low speed. Other methods, including sub-slab ventilation, sealing of floating slab edges, and sealing of cracks and sump pump covers will still be needed. No two radon problems are the same, so make sure you deal with a pro. Don't base your decisions on a result from a test product sold at retail, only a trained professional like an Environmental Engineer or an Industrial Hygienist can give you the corrrect, accurate results. Like mold remediation, this is for those who have the proper tools and training to handle it. I hope you find this useful.
