(Primarily for homes with radiant hot water or electric
baseboard heating. See figure 1.)
Moist, stale air is exhausted from the high humidity areas in
the home, such as bathrooms, kitchen and laundry room.
Fresh air is supplied to bedrooms and principal living areas.
If required, bathroom fans and a range hood may be used to
better exhaust stale air.
Homes with more than one level require at least one exhaust
register at the highest level.
