Radiant Floors – Air
An ineffective choice for residential applications. Although they can be combined with solar air heating systems, the system suffers from the obvious drawback of only being available in the daytime, when heating loads are generally lower. Because of the inefficiency of trying to heat a home with a conventional furnace by pumping air through the floors, the benefits of using solar heat during the day are outweighed by the disadvantages of using the conventional system at night.
