Gas Water Heater Operation
Air for combuson passes through
the boom of the water heater
into the combuson chamber. Gas
ows into the burner and is ignited
by the pilot ame.
Heat from combuson rises
and contacts the tank boom
head being transferred through
the steel into the
water.
As the heated water rises, cooler
water sinks to the boom of the
tank.
The ue pipe carries away
combuson by product gasses
as well as acng as a heat
transfer surface. At the center
of the ue is a bae. The bae
helps transfer heat by
deecng hot combuson
gasses against the sides of the
ue where the heat is
transferred into the water.
