Burning wood has always been a heat source for some people, but with wider knowledge of environmental issues surrounding the burning of fossil fuels and a desire for energy independence, burning wood is gaining popularity. Wood is a renewable natural resource and is less costly than fossil fuels if you cut it yourself. If properly air-dried and burned in an efficient, modern wood burning stove, the heat from a cord of native hardwood is nearly equal to that of burning 130 gallons of No. 2 fuel oil.
There are two types of wood burning stoves: catalytic combustor and noncatalytic.
