A caption appears on screen. It reads “Wood-Burning Stoves.”

The Narrator says RISING FUEL OIL
AND HYDRO COSTS
HAVE FORCED
MANY CANADIANS
TO LOOK TO NEW WAYS
TO HEAT THEIR HOMES.
ONE NEW ALTERNATIVE
IS ALSO THE OLDEST:
THE WOOD-BURNING STOVE.
BUT STOVES HAVE CHANGED SINCE
OUR GRANDPARENTS' TIME.
IMPROVED DESIGN
AND MANUFACTURING
HAVE PRODUCED MORE
EFFICIENT WOOD BURNERS.

Factory workers weld iron pieces.

The Narrator continues WHILE FIREPLACES CAN ACTUALLY
STEAL HEAT FROM THE HOME,
A PROPERLY PLACED WOOD STOVE
CAN HEAT AN AVERAGE HOME
WITH ONLY TWO TO
FIVE CORDS A YEAR.
AND WOOD IS CATCHING ON.
LAST YEAR, 40,000 WOOD STOVES
WERE BOUGHT BY CANADIANS.
AND THERE ARE APPROXIMATELY 150
MANUFACTURERS IN BUSINESS.
BUT HOW SAFE AND EFFICIENT
ARE THESE NEW DESIGNS?
THE CANADIAN COMBUSTION RESEARCH
LABORATORY IS DEVELOPING
A STANDARDIZED EXPERIMENTAL
TEST PROCEDURE TO MEASURE
THE EFFICIENCY OF
WOOD-FIRED APPLIANCES.
THE NEW TEST PROCEDURES COVER
INEFFICIENT FRANKLIN STOVES,
EFFICIENT AIRTIGHT BOX STOVES,
AND COMBI-FIRES, WHICH CAN BE
OPENED TO ENJOY THE FIRE
OR SHUT LIKE AN
AIRTIGHT STOVE.
DESIGN INNOVATIONS LIKE
MOVABLE BAFFLES TO FORCE
COMBUSTION GASES
THROUGH A LONGER PATH
ARE PROVING TO BE BOTH
SAFE AND EFFICIENT.

A close-up shot features wood burning.

The Narrator continues TEST METHODS DEVELOPED BY THE
COMBUSTION RESEARCH LAB
IN 25 YEARS OF HYDROCARBON
FUELS' RESEARCH
HAVE BEEN ADAPTED TO WOOD FUELS
AND INTEGRATED WITH COMPUTERS.
THE HEAT LOSS UP THE CHIMNEY IS
MEASURED OVER THE COMPLETE
BURNING CYCLE FROM NEW LOG,
THROUGH FULL FIRE, TO ASHES.
THE RESEARCH OBJECTIVE IS TO
PRODUCE EFFICIENCY RATING
AND OPERATION PROCEDURES.
ONCE PARTICULATES ARE SEPARATED
FROM THE FLUE GASES,
DATA ON SEVEN TYPES OF GASES,
MOISTURE, HYDROCARBONS
AND TEMPERATURE
ARE MONITORED.

A hose pumps air into a glass jar containing a brown liquid.

The Narrator continues EVEN THE WEIGHT OF THE
STOVE AND WOOD FUEL
IS CONTINUOUSLY
MONITORED AND RECORDED.
THIS ENTIRE BARRAGE OF DATA
IS DIGITIZED AND THEN
PASSED TO COMPUTER WHICH
DELIVERS A PROFILE
OF EFFICIENCY THROUGHOUT
THE BURNING CYCLE
FOR EACH TYPE OF STOVE.

A ticket comes out of a computer.

The Narrator continues FINALLY, PARTICLE SAMPLES
SUBMITTED FOR LABORATORY
ANALYSIS PROVIDE A MEANS FOR
ASSESSING CREOSOTE FORMATION.
CREOSOTE IS A HIGHLY FLAMMABLE,
TARLIKE WASTE MATERIAL
PRODUCED BY THE BURNING
OF WET OR GREEN WOOD,
OR CONSTANTLY OPERATING
AN AIRTIGHT STOVE
IN THE SLOW-BURN MODE.
IT'S THE SINGLE MOST SIGNIFICANT
CAUSE OF CHIMNEY FIRES,
AND CAN JEOPARDIZE THE
INSURABILITY OF SOME
WOOD-HEATED STRUCTURES.
THE CANADIAN COMBUSTION RESEARCH
LABORATORY HAS ALREADY
MADE EXTENSIVE FIELD TESTS
ON THE EFFECTIVENESS
OF OIL HEATING.
THESE SAME TEST HOMES
ARE NOW BEING FITTED
WITH WOOD-BURNING
APPLIANCES SO THAT
LABORATORY FINDINGS
CAN BE CORRELATED
TO ACTUAL STATISTICS.
THIS ONGOING RESEARCH
PROGRAM WILL HELP
BOTH MANUFACTURER AND HOME OWNER
SAFELY AND EFFICIENTLY
MEET THE INCREASING ENERGY
DEMANDS OF THE FUTURE.
