The present invention provides a heating apparatus for providing radiant
heat to a passenger compartment of a vehicle. Heated fluid is transported
from a heat source positioned outside of the passenger compartment. A
supply manifold selectively dispenses heated fluid into a plurality of
tubular members extending into the passenger compartment. The heated fluid
provides radiant heat for heating the passenger compartment. The fluid is
transported within the tubular members to a return manifold, wherein said
fluid is recycled to the heat source.
