Your heating system is only partly responsible for air quality issues. Cooking, bathing, laundry, house plants, breathing and perspiration all contribute to indoor air quality, as well as chemical off-gassing from building materials, textiles and interior finishes. I think that a "heat recovery ventilator" is one of the best investments that you can make. They are simple and reliable, and your building Inspector may actually require that one be installed in your home.
