Using wood heat reduces dependence on the fluctuating prices of traditional heating fuels. Wood is one of the least expensive heating fuels available. Many outdoor wood furnace owners have ample supplies of wood available on nearby forestland and harvest their own firewood. Many logging services, wood products manufacturers, and other companies have waste wood available at little or no cost to you.
Wood is a totally renewable resource, which, when burned, results in no net carbon dioxide increase. Carbon dioxide is part of the natural plant-growth cycle and occurs naturally when plants rot. On the other hand, fossil fuels when burned, release carbon dioxide. This causes a net increase in carbon dioxide, which is believed to be responsible for the “greenhouse effect”.
