Backcountry Boiler Wood Burning Stove for Backpacking
Below is Tom Baskin using his Backcountry Boiler chimney stove to heat 6 cups of water with a few sticks. It took about 6 minutes. The fire chamber is on the bottom, and the chimney is surrounded by a water jacket. When the water is hot you remove the cap on the water jacket and pour out the water you need.
