Definition
A system to heat and cool buildings that relies primarily on
radiation heat transfer. Typically, heated or chilled water is
circulated though floor or ceiling panels to condition the
space

CONCLUSION
The small temperature difference means that about 30% to 50% of
the ceiling or almost the entire floor area must be available as
heat transfer surface.Radiant floor tubing can also be used to cool
a house, but presently it is only appropriate for dry climates.
