Kerosene stoves are commonly used in many third world African and Asian countries. The brand that I have is the Butterfly stove from Malaysia. It is inexpensive, reliable, and readily available. A company that I have dealt with and found reliable is St Paul Mercantile (a link to their site is located on the right side of this blog shown as Family Preparedness Kit). The Butterfly stove is available in one and three burner models. The single burner model will run for approximately 12 hours on a half gallon of fuel. The wicks are easily changed and are good for up to six months.
Ten gallons of kerosene would provide you with approximately 240 hours of cooking on a one-burner stove. Depending on your climate, if you share the cooking with a solar oven on sunny days, you could cook for a year with a relatively small amount of kerosene 10 to 20 gallons.
There are several versions of the stove with different wick designs. I have the original design which uses about 25% less fuel than the later models. This version currently sells for about $65.00 for a one-burner model. With just the two of us, we have the one burner model; other members of my family with children have the two-burner model. These have proved to be very practical stoves and I really like them.
