Santa, The Chimney Expert
By: Judi Stuart

“…And laying a finger aside of his nose, and giving a nod, up
the chimney he rose.” Does that make
Santa an expert on what one can find in a chimney? He does have plenty of experience.
Since 1900, the number of homes
constructed with chimneys has steadily declined. Will Santa have to change his
methods of operation? Will some animals have to change their habitats?
Before the eleven hundreds,
dwellings had fire pits and the smoke traveled to the ceiling and throughout
the structure. Spaces near the top were
used for storage and hanging meats, thus taking advantage of the preservation
qualities of smoke.
When early attempts to control the
smoke led to the development of the chimney, a second floor could be added to
homes. By the fifteenth and sixteenth
century, chimneys were built of brick and found in most homes.
Chimneys are busy places and can be the residence for several
types of creatures. Bats, blue-tailed
skinks, squirrels, spiders, raccoons, chimney swifts and other animals take
shelter within these structures. Tales
of wildlife coming into a house through the chimney are common.
Found in North Carolina and most eastern states, the gray,
cigar-shaped chimney swift was once a crevice dweller, but eventually
transferred to the warm environment of the chimney to build its nest. The small birds spend most of their waking
hours flying and catching insects to eat while in flight. They quickly dive into the water to bathe and
come up shaking the water from their bodies.
Many modern chimneys are covered and have narrow flues, which
are not suitable for nesting. The glue-like
saliva, which the bird uses to cement its half-saucer nest to brick walls, no
longer works.
In 2012, chimney swifts were added to the watch list because
they are in steep decline. Swifts
migrate to South America and spend the winter in Peru, Ecuador, Chile, and
Brazil. Although the swift is gone, the
nest will remain in the chimney.
Santa might also
encounter a nasty substance called creosote, which is a by-product of
incomplete combustion. Burning fossil
fuels such as wood and coal produces water, carbon, and volatile chemicals
which condense on chimney surfaces. All
forms of creosote are highly combustible.
Several factors can make the build-up worse. Restricting air flow by closing fireplace
doors, failing to open the damper completely, burning unseasoned wood, and
overloading a firebox can all accelerate the build-up.
This black, oily substance can eventually become a thick
deposit which reduces the airflow in the chimney and may cause a chimney
fire. Most of the time, the fire is
contained inside the chimney, but if the fire is hot enough, it can ignite
materials close to the chimney and cause a house fire. Homeowners should have their chimneys cleaned
regularly by a professional.
Whatever Santa encounters, he always gets the job done with
the help of many elves, of course.
