EPA Phase 2 Certified
The World’s #1 Gasification Furnace
#Hand Crafted Excellence
The EPA Phase 2 Certified, Kuuma Vapor-Fire 100 is our largest Vapor-Fire wood burning furnace. The wood length is approximately 20″ and requires seasoned wood that has an 18-28% moisture content. It has a large 2-speed blower that delivers 500 to 1500 CFM (cubic feet per minute) on demand, controlled by a thermostat. It can stand alone as a central furnace, or be used as an add-on to an existing oil, gas, or electric furnace.
The bonnet opening is 2’x2′ and your heat duct outlet should be 180-200 square inches to prevent excess back pressure on the blower system. It gives you a clean, safe, and automatic front to back burn that delivers very even heat for 10-12 hours per load followed by many hours of coals. Even heat output results from the front to back burn principle in our Vapor-Fire wood burning furnace.
A properly installed Vapor-Fire 100 will comfortably heat a home up to 3500 square feet including your basement. It may heat larger homes based on your geographic location and the physical design of your home. The heating capacity will also depend on how well the premises is insulated and if doors and windows provide good seals. A properly installed furnace will require adequate cold air returns – just like any other forced air furnace.
The VF-100 is best installed in a central location in the home or shop to allow for even distribution of warm air via heating ducts. For this reason, VF-100’s are often installed in basements or garages.
