rosive character of condensate must be addressed in condensate piping
material selection.

Water
Water is used extensively in modern cooling and heating practice be-
cause it is an effective heat transport medium and because it is con-
sidered simple to deal with. Because the water system can be essen-
tially closed, there are fewer corrosion and water treatment problems
than with steam. Except in high-rise buildings, system static pres-
sures are low and temperature changes are not severe, allowing the
use of low-cost materials and simple piping support systems. An ex-
ception is high-temperature hot water, discussed later in this chapter.
