Means for heating water by wood burning

Patent ·
OSTI ID:6295253

The wood burning water heating means of the present invention utilizes a firebox having a grate adjacent the lower end and a flue opening positioned downward from the upper end thereof. The flue extends into the firebox so as to deflect rising hot gases prior to their exit through the flue opening. A main draft opening provides communication of air below the grate to provide oxygen for the fire. A secondary draft opening is provided above the grate for introducing air in such a manner that oxygen will be provided immediately below the flue to facilitate combustion.
