Introduction
Heating is the first word in the acronym HVAC. It is the most impor-
tant part because without heating mankind would have difficulty in
surviving. Proper design of the heating system is even more critical
than that of ventilation or cooling. Human history began to develop
with the discovery and control of fire which increased people’s ability
to survive in a harsh environment. In modern heating system design,
two primary concerns are proper system
sizing,
to achieve comfort,
and system
reliability
. Capital cost, operating cost, and pollution con-
trol are secondary in consideration. Pollution control is addressed by
code authorities. Energy conservation and operating costs go together
and have a considerable effect on life-cycle costs.
These concerns and many others are addressed in this chapter.
