Addition Comfort And Saving, Figure Figure

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.
