Apparatus for producing heat from burning fuel comprising, in combination: combustion chamber means, including a front wall, a rear wall, a first and a second side wall, a floor, and a ceiling for burning fuel; primary settling chamber means disposed adjacent the combustion chamber and communicating therewith for receiving a flow of combustion gases and products of combustion from the burning of fuel in the combustion chamber in which heavier unburned products settle out of the flow of combustion gases and products of combustion; passage means extending between the combustion chamber means and the settling chamber means through which the combustion gases and products of combustion flow and disposed adjacent the ceiling of the combustion chamber for providing a vertically upward flow of the said gases and products from the combustion chamber and a vertically downward flow of the gases and products from the passage means into the primary settling chambers means; secondary settling chamber means disposed adjacent and communicating with the primary settling chamber means for receiving the flow of combustion gases and products of combustion from the primary settling chamber means in which lighter unburned products of combustion settle out of the flow of combustion gases and products of combustion; damper chamber means disposed above the secondary settling chamber means for receiving the flow of combustion gases and products of combustion from the secondary settling chamber means and comprising a tertiary settling chamber in which the lightest unburned products of combustion settle out of the flow of combustion gases and products of combustion, and including a damper opening between the secondary settling chamber means and the damper chamber means, and an adjustable damper adjacent the damper opening and movable to control the flow of combustion gases and products of combustion from the secondary settling chamber means to the damper chamber means; chimney flue means communicating with the damper chamber means for receiving the flow of combustion gases and products of combustion from the damper chamber means and for conducting them out of the apparatus; wall means disposed about the combustion chamber means and comprising a plurality of panels defining the outer walls of the apparatus; and heated air chamber means disposed between the combustion chamber means and the wall means through which air flows for receiving heat from the combustion of fuel in the combustion chamber means.
