Long, long ago, primitive cavemen
were kept warm by campfires. The space
inside their cave was warm as long as the
fire kept going. But if it went out, they
would freeze. That is why someone had
to tend the fire all through the night.
When man discovered that fire warmed
stones, he made a crude hearth and kept his
fire going within the circle. Even if the fire
went out at night, the cave was kept warm by
the red-hot stones.
Man’s next home was a dugout in
the ground. He moved his stone
hearth there, and had a fire to
warm his house. However, the
fire also filled it with smoke
and soot, so the door had to be
kept open to let it out. As the
smoke drifted out the door, the
warmth inside did, too.
At last man invented another way for
smoke to escape by constructing a chimney
over the hearth. Still, a lot of warmth escaped
through the chimney at night. Then people
began covering the top of the chimney with a
large stone after the fire died down.
Many, many years were to go by before
people learned how to make and fire bricks
and then invented a sliding metal plate called
a damper to keep the warmth in a stove.
The oven bricks became very hot and
stayed hot for a long time, as the tamed fire
blazed inside this Russian oven. The oven
warmed the house. Here the family’s food
was cooked and its bread was baked.
Even the grandest palaces were heated
by the same familiar campfire, locked
away in a brick fireplace with a tall
chimney.
A Dutch oven was much better
than an open fire place. It did not
use up as much firewood and kept warm much
longer. Its two shortcomings were that heavy fire-
wood had to be carried up many flights in the tall
houses and someone had to keep an eye on the oven
as long as the fire was burning.
It ‘was no easy job to cart logs from the
lumber yard, saw and split the wood and then
carry the firewood to every oven and stove.
This was expensive fuel and hard to handle.
Besides, it produced heaps of ashes that had to
be carried out of the house. Acres of woods had
to be chopped down to warm the buildings, for
each stove consumed many a tree in a year.
Then a new type of heating system was
invented, and hot water boilers were installed
in the cellars of large houses. Now, instead of
brick ovens, iron pipes and radiators were
installed in the rooms with boiling water from
the boiler to heat them.
A radiator is a hot-water stove.
Set under the windowsill, it is out
of the way..The water coursing
through it day and night keeps
the metal hot. Though snow is on
the ground outside, it is summer
indoors. A radiator does not give
off smoke or fumes and_ will
never set a house on fire.
Coal burns brightly in these large furnaces, heating water for the pipes
and radiators in every room on every floor. When the water cools it comes
back down to the boiler to be heated again, continuing on this endless circle
day and night. Now one man kept a hundred apartments warm all by
himself.
Keeping coal furnaces going day and night became too bothersome, and
SO gas pipes were installed. Gas did not have to be delivered by huge trucks
or shovelled into the fireboxes. It flowed through the pipes and into the
furnaces itself.
All that had to be done now was to
check on the temperature. If the furnaces
got too hot, the thermostat was turned
down. If they began cooling, it was
turned up.
Indeed, man had discovered a way to
heat his home as marvellous as a:‘story in
a book of fairy tales.
