Most Canadian homes,
especially- older ones, are
heated by Oil furnaces. In
Quebec and -the Maritimes,
residential heating ISalmost
exclusively by oil.
In the ',conventional oil
furnace, heating is ac-
complished by mixing a
spray of Oil droplets with air
and igniting ittagive a flame.
To get t.110, most heat, your
fuel should .be burned com-
pletely. The, oil -air mixture
shoulduse the. minimum
quantity of air that will give a
"clean" flan*. Smoke at the
tip of the flame will cause
soot deposits, and rob you of
- -
How well is your furnace
working? Three ways to find
out yourself: The major care
of your oil furnace should be
left to a qualified serviceman.
But there are a few points
that you can look after
yourself:
Look for a dirty liable. In
the front of your furnace
a you'll find a flap covering a
small hole. You can peek in
here to see the flame.
(Careful! If your furnace has
been on for a couple of
minutes the flap will be hot.)
Black smoke coming from the
tip of the flame is a sure sign
that your burner needs ad-
justnient. Call a serviceman.
Check or soot. When your
furnace is not operating, take
a flashlight and have a look
inside the box. How much
soot has built up? The more
soot, the less efficient the
furnace - and the more it's
costing you to heat your
home. If there's a soot build-
up, arrange for an ad-
justment and cleaning. '
Even with a well-
functioning burner there will
be sense buildup of soot
during the winter. This
happens when the burner
switches on, before the fuel
011 is properly mixed with the
air. The finale thing happens
when the burner switches off.
You can buy a "clutch
coupling" or "Solenoid
valve" that will help to
counteract tills. Your ser-
viceman will have the pries
and can install either one for

This valve bumps open -and
shut as the wind blows and as
the furnace cuts in and out.
(Occasionally mistaken for a
noisy burglar!) It allows cool
air to be drawn from the
basement into the chimney,
acting as a buffer to keep
most of the warm air in the
furnace. Check the damper

it it sticks when you push it,
clean The hinges and give
them a drop of oil. When the
furnace is on, check to see
that it opens. If it centimes to
stick in any position, it means
you're wasting energy and
money. Can your ser-
viceman. Twice‘a-year
service can cut 10 per cent
from your heating bin.
Both furnace and burner
should be checked and
cleaned twice a year - once in
summer and once midway
through the winter. This will
save at least 10 per cent on
your fuel bill. Fax every $400
you now pay for fuel on, an
efficient furnace -burner
combination will save you at
least $40.
Electric furnaces
Heat pump
new source
In Canada there are nolo a
few instances of central
electric furnaces, with an
electric element providing
the heat source. There is little
maintenance that can be
carried out on these units.
The heat pump is a, new
heat . source fbr both
residential and commercial
use. It's basically a
refrigerating machine which
takes heat from a low-
temperature source (outside
air) and delivers it inside the
house at a higher tem-
perature. Fax one kilowatt of
power consumed, the system
can produce the equivalent of
about three kilowatts of heat
in the house. It could be three
times more efficient than
electric resistance heating.
Heat pumps are now being
evaluated for the Canadian
winter, and with some
modifications may come into
wide use. The initai cost is
high, but they may prove to
be very useful and
economical heat sources.

Typical 011 Burner
If all Canadians saved this
10 per cent. Canada would,
save $90 zillion and T.S"
million barrels of oil a year.
You can see how every drop
we save can swell into big
savings for the country. Here
are the six important checks
your serviceman should
carry out twice. a year. Make
sure he does :
Remove soot. The firepot,
heat exchanger and pipes
should be completely
cleaned. Some experts go so
far as to sayyou should be
able to see your reflection in
the clean heat exchanger.
Tell that to your serviceman!
Check stack temperature.
The largest heatipss will be
in hot gases going' up the
chimney. To keep this to a
minimum, your serviceman
should measure the tem-
perature of the gases leaving
the furnace. It should be
between 300 degrees F (148
degrees C) and 450 degrees F
( 230 degrees C). Often this
temperature is over 600
degrees F (316 degrees C).
Much too high. It can be
reduced by increasing the
speed of the circulating fan.
This usually requires an
adjustment of the motor
pulley. If this doesn't work -
or if you have a hot water or
steam heating system -
possibly the burner is putting
out too much heat fax the
furnace and you need a
smaller oil nozzle.
Pa*
Try a smaller nozzle -size.
Try a nozzle -size 20 per -teat
smaller or the lowest firing
rate recommended for your
furnace - whichever results in
the greatest improvement.
Your flue gas temperature
will drop., furnace efficiency
will increase and your
comfort level should not
change. If you feel cold when
the furnace is operating, use
a nozzle -size only 10 per cent
smaller than the original.
Better still, irnprove tile
insulation in your house.
Check smoke number. Your
serviceman should draw a
small amount of stack gas
through a smoke density
measuring device. In an
efficient furnace, the stack
gas will be virtually free of
soot. If not, the burner should
be re -tuned.
Check carbon dioxide level.
The amount of carbon dioxide
in the stack gas will give a
further measure of the fur-
_ nace's thermal efficiency.
Measured in this way, the
best efficiency you should
expect is about 80 to 85 per
cent.
Check draft and adjust,
barometric damper. Your
serviceman should check the
draft or draw of air through
the firebox and in the stack.
The barometric damper
should be adjusted if
necessary.
There are a number of
other checks and procedures
which a good serviceman will
undertake. Ask your ser-
viceman to do them on each
visit.
