Best Outdoor Wood Furnaces

freeheatmachine.com To understand the HybridFire, one needs to understand the basic outside furnace. Most all outside furnaces are in the basic grouping. They heat homes but at what effort? Most of the heat and smoke (smoke is unburned gas) is wasted. These basic furnaces use lots of wood and homeowners clean out ashes every few days to every few weeks. The HybridFire is future technology today. The HybridFire shares some kinship to a crossdraft gasifier where air enters into the combustion chamber at a high velocity through a single nozzle and induces tremendous circulation. This air flow moves through the fuel wood and charcoal producing high temperatures in a small area (up to 1300º F in the fire bed. During full combustion, fire chamber temperatures reach over 1100º F, yet stack temperatures are under 200º F at the chimney. Why is this so important?
