RADIANT VS. DRY BULB TEMPERATURE (GRAPH 1)
    In theory, one might expect to find a great difference between radiant and dry bulb temperatures in a space heated by a wood burning stove.  It was our initial assumption that the average dry bulb temperature would be considerably lower than the average radiant temperature throughout the room.  This assumption seemed appropriate due to the fact that a radiant heat source is responsible for heating surrounding surfaces and not directly heating the air.  The warmth felt from the stove is analogous to the way the sun heats our bodies even on cold winter days.
    However, the data shows a less dramatic difference between the dry bulb and radiant temperatures than what was expected.  Perhaps this difference occurred from the unseasonably warm and sunny weather during the period of analysis.  It is also important to consider the influences of the large south facing windows which provided solar gain in the room.  In an ideal experiment the sun would be prevented from entering the room and the outside temperatures would be more typical of winter conditions.
    In spite of the unfortunate nature of scientific experiments, there are clear facts presented by this graph about the thermal conditions of the space.  Reading from left to right there is a sharp increase in the pink line indicating the period in which the fire box was emitting the maximum amount of radiant temperature.  This is also the period with the greatest difference between the radiant temperature(pink) and the dry bulb temperature(purple).  As a result, the heat felt in the space would predominately be a product of the radiant warmth of the stove.  Later in the day, however, the difference between the radiant and dry bulb temperature diminishes and the room levels out at a comfortable temperature of 72 degrees Fahrenheit.

MEAN RADIANT TEMPERATURES THROUGHOUT THE ROOM (GRAPH 2)
    Graph 2 indicates the stove's effectiveness in providing a consistent level of radiant heat throughout the room except for a four and a half hour period following the initial firing.  The zone closest to the stove (zone 2) receives the greatest amount of radiant heat for that period.  As noted earlier it is not until the fire burns out that the room temperature begins to equalize.  Eventually, the extreme zone of the room (zone 4 with a distance of 18 feet from the stove) is only a few degrees cooler than zone two, which is 6 feet from the stove.
    It is also apparent that the surface temperature of the stove (dark blue line) peaks approximately six hours after the fire burns out.  Being constructed entirely of soap stone, the stove conducts heat effectively through the entire thermal mass.  In addition, the stove is designed to channel smoke in a meandering pattern around the fire box as well as through the entire cavity of the stove before releasing it to the atmosphere.  This maximizes total heat output from the wood exposing the stone to the highest possible temperatures for optimum absorption.  As a result, the stove continues to heat itself long after the fire burns out.  The surface temperature of the stove does not drop below 108 degrees Fahrenheit before the following day's firing.

THE NEAR AND FAR ZONES (GRAPHS 3 AND 4)
    These graphs show the greatest temperature difference between zones 2 and 4.  This difference occurs at the initial firing and gradually diminishes as the fire burns out.  The fire burns for approximately two hours, producing the maximum radiant temperature of 94 degrees Fahrenheit at the closest zone(2) and a maximum temperature of 85 degrees Fahrenheit at the furthest zone(4).  Three hours later the radiant and dry bulb temperatures of both zones(2 and 4) are within a three degree difference relative to each other.  Through the night the temperatures fall at a slow, constant rate (about 5 degrees Fahrenheit) and by morning there is still little difference between the radiant and dry bulb temperature in the near and far zones.
