Culvert Wood Stove
"The stove cost just 3 to 4 hours of time," says Jim Knowles, of Anabel, Mo., who heats his 1,200 sq. ft. feed room with a wood stove he made from a culvert and other junked materials.
Knowles used a standard 2-ft. corrugated culvert section 3 ft., 6 in. long for the body of the stove. He welded in a flue 1 ft. back from the rear. The front door and rear plate are made from 1/4 in. steel.
The door, with an adjustable air inlet, hinges and locks open for adding wood. The stove is practically air-tight, says Knowles. As in many modern wood stoves, there is no grate. Angle irons and pipe serve as legs. Logs over 3 ft. long can be burned.
Knowles says culverts make excellent stoves because the corrugations provide more surface area for radiating heat, making the stove more efficient. Because the culvert is 2 to 3 times as thick as the metal in a steel barrel, the stove is expected to last much longer than a common barrel stove.
