Lots of interest in woodlots, stoves
It seems a funny topic for July, but
woodstoves and woodlot management were
discussed when over 30 people attended a
woodbnrning workshop held at the
Lucknow Conservation Centre recently.
Conservation centre employee Barb
Zettler told the group that air -type
woodstoves are more efficient than old-
fashioned stoves because the operator has
more control over the fire. Dampers control
the rate of Clow of air and in turn, the rate
the fire burns at.
"In other words they have a fire when
you get up in the morning which is kind of
nice," she said. Some people with efficient
woodstoves have to light them just once a
winter.
Two Types
There are two major types of wood
burners. she said. One is the radiator type.
More than half the useful heat corning from
the stove is radiated from it. The circular
type has a jacket around the stove and the
air is allowed to circulate between the stove
and sleeve. More than half the useful heat
coming from this type of woodstove is from
the circulating air.
She described several of the stove
designs and how each makes use of
convection currents to burn wood gases
given off by burning wood.
Woodstoves come in many capacities
and some can heat a whole house. Prices
vary from $200 to over $800.
Michael Ward, a Blyth distributor of
wood stoves spoke to the group about their
installation. Woodstoves must have fire-
proofing underneath them to protect the
floor. he said and should be three feet away
from walls.
He recommended that horizontal
stretches of stove pipe shouldn't bc longer
than six or eight feet because of the
buildup of creosote which can catch firc.
Anyone thinking of hooking a woodstovc
toan old masonry chimney should examine
the chimney very carefully, because loose
bricks and stones can partially block thc
exhaust from a fire. A narrow spot is the
logical place for creosote to build up. Mr.
Ward said. so it can be a real fire hazard.
Shopping
He told the workshop that pcoplc
shopping for a woodstovc should be careful
and know what they're buying.
Marvin Smith of the Wingham office of
the Ontario Ministry of Natural Resources
IMNR) who talked about woodlot manage-
ment said that tree identification is thc first
"...the best name around livestock today..."

step in management because people
should know which trees arc more
commercially valuable.
He said the woodlot owner should
determine whether he is managing the
woodlot for firewood or for commercial
sale. In this arca, firewood (while still
standing) is worth only two to five dollars a
cord, while high quality timber can be
worth $75 a cord, he said. He was talking
about a cord of wood eight feet long, by
four feet high. by four feet.
Economical
When chopped. firewood at $55 to $70 a
cord is an economical buy. he said. The
heat in a cord of wood, is equal to the heat
in 110 to 140 gallons of fuel oil, he said.
Thick stands of trees should bc left
densely populated so they will grow tall
and straight and be commercially
desirable, Mr. Smith said.
When the trees have reached a desirable
height, thc woodlot manager thins out
deformed trees and trees of Tess valuable
species. In a casc where one tree is fighting
another for sunlight. the manager should
cut down the less valuable tree and use it
for firewood. giving the other a better
chance to grow quickly.
