It takes 4 million years to create oil, gas and coal. It takes 40 years to grow mature trees. It takes only 4 months to grow a crop of grain, real renewable fuel, every year a new crop. The sides, back, top and bottom are cold, and therefore all our stoves are zero clearance with no chimney required. All stoves and furnaces are auger fed, forced draft and power-vented.
Fresh air is drawn from outdoors for combustion.
The air that is heated comes from inside the home and the two systems are separate. All our stoves are exempt from EPA pollution standards because they bum so clean, no creosote, no smoke, no carbon monoxide.
