_•:.• Most Canadian harries,
especially older ones, are
heated - by oil furnaces. I-11
Quebec and the Maritimes,
residentia4heating is almost
exclusively by oil.
n, the conventional oil
furnade, beating is ac-
complished by mixing a
spray of oil droplets with air
and igniting it to give a flamb. •
To get the most he a t, your
fuel should be burned com-
pletely. The oil -air mixture
should use the minimum
quantity of air that will give a
"clean" flame. Smoke at the
tip of the flame will 'cause
soot deposits, and rob you -of
heat. •
How well is your furnace
-vvorking? 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, flame: In
the front ..of your furnace
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-
justinent. Call a serviceman'. '
Check for 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 fess 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
Electric furnaces
be some build-up of soot
during the winter. This
happens when the burner
switches• on, before the fuel
oil is properly mixed with the
air. The same thing happens
when the burner switches off:
_You can buy 'a "clutch
coupling" ..or "Solenoid
Valve" •that will.. help to
eounteract this. Your ser-
viceman will have the prices
and can install either one for
you.
Check the barometric
damper.' You'll see the
barometric damper on :the
pipe leading from furnace to
chimney.
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 dra*n from the
basement into the chimney,
acting as a buffer to keep
most of the warm air in the
furnace. Check the damper
and be •sure it's swinging
freely.
If it %ticks 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 continues to
stick in any position, it means
you're wasting energy and
money, • Call your ser,-
viceman. Twice -a -year
service can cut 10 per cent
from your heating bill.
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 101ter cent on
your fuel bill: For every $400
you now pay for fuel oil, an
efficient furnace -burner
combination will save you at.
least $40. •
Heat pulthp
new source
In Canada there are now a
• few instances of central
electric furnaces, with an
electri.c element providing
the heat source. There is little
maintenance that can be
• carried out on these units.
The hea/ pump is a new
heat source for 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
o '
house at a higher tem-
perature. For one kilowatt of
power consumed, the system
can produce the equivalent of
about three kilowatts ofheat
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 inital cost is
high, but they may prove to
be very useful • and
economical heat sources..

chimney. To keep this to a
minimum, your- serviceman
.should measure the tem-

between 300 degrees F (148

( 230 degrees C). Often this

This usually requires' an

or if you have a hot water or

possibly the burner is putting
out too much' heat for the
furnace, and you need a

rate recommended for your
furnace - whichever results in
the greatest •improvement:.
Your flue gas temperature'
will drop., furnace efficiency
will increase and your

change. If you, feel cold when
the furnace is operating, use
a nozzle -size only 10 per cent
smaller than the original.
'Better still, improve the
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 leyel.'
• The amount of carbon dioxide
in Ihe, stack gas will give a
further measure of the fur -

'Measured in this. way, the
best • efficiency 'you should
expect is about 80 to 85 per
cent. •
Check draft and adjust

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
whicha good serviceman will
uncLertake. Ask your sev•
viceman to do them on each
visit.
