weather, it will not be large enough to keep the
house
warm in cold weather. This could cause the furnace to
overheat and a loss of heat up the chimney. The result
then is a compromise which is neither efficient or com-
fortable. Woodchuck furnaces, however, have a three
speed circulation blower which can be adjusted via a
three position rotary switch on the Comfort Control
Center. This allows the user to select the blower speed
to meet the air movement requirements of the installa-
tion. In addition, when the weather is mild and the fur-
nace is operating at a lower output, the blower can be
set on low to gently move the air. Similarly, when it is
cold and the furnace is operated at higher levels of
heat, output can be switched to higher speeds.
But how can all this improve the efficiency of your
home? As figure 1 illustrates, heated air rises away
from the living area and stratifies. This causes large
temperature differentials between the ceiling where
heat is lost rapidly through conduction and the floor
where children often play. By allowing for continuous
air movement, even during periods of low heat output,
this stratification is not allowed to take place. You are
more comfortable and lose less heat through your ceil-
ings as illustrated in figure 2.
This situation can be especially troublesome in
multi-level homes as illustrated in figure 3. As soon as
the blower shuts off, the air in the home begins to strat-
ify; warm air rising to the upper levels and cool air col-
lecting in the lower levels. The lower levels become
increasingly uncomfortable until the blower turns on
again. Unfortunately, the upper levels are still warm so
they become uncomfortably warm before the blower
turns off. By allowing for a steadier, more continuous
operation of the blower the entire house stays at a
more constant and comfortable level, figure 4.
ADDITION COMFORT AND SAVING
Options are available for your Woodchuck furnace, and
one of these deserve special mention. The Aqua-Si-
phon is capable of pre-heating your domestic water
free of charge during the heating season for additional
saving to you.
