Outdoor furnaces, also referred to by some as outdoor hydronic heaters or outdoor wood boilers, burn renewable, biomass fuels that are “carbon neutral,” such as wood and wood pellets. This means they don’t generate a net increase in greenhouse gas emissions, as do fossil fuel generated electricity, natural gas, fuel oil, kerosene, liquefied petroleum gas, and coal. Outdoor furnaces actually lessen our dependence on foreign oil and fossil fuels.
