ABSTRACT:
The furnace for burning wood or coal has a cabinet with a front wall and interconnected spaces between the inner and outer walls at the sides, top, bottom and rear. One of two outer walls have an inlet and outlet for flow of air to be heated. There are aligned flue openings in the upper portion of one of the sets of spaced walls. A grate and an ash pan below are mounted within a lower portion of the cabinet. The front wall has at least one opening closed in an airtight manner by one or two doors. A damper, having a pipe and plate pivotally mounted on the top of the pipe at its front end, is connected to a bimetallic thermostat above it. Both are mounted on the front of the furnace. The thermostat is mounted for movement to open the damper. The front wall of the cabinet or the door, when there is one door, separates the thermostat from the fire chamber within the cabinet above the grate. The furnace construction separates entirely, or almost entirely, the thermostat from any air being heated during flow through the interconnected spaces so that the thermal energy sensed by the thermostat is entirely or primarily radiant energy from the front wall of the cabinet or the door between the thermostat and the fire chamber.
