2007 Heater Testing at Shawville

Test HK-H18
March 10/07

Large maple. Medium warm heater. 49lbs
Previous fire: 36 hours.
Grate air closed. Ashbox door open (similar to old HeatKit air)
Slow start after kindling burned.
Low opacity (particulates), medium CO, medium efficiency.
For a lukewarm heater with this air supply, the fuel was too large for
the load size. A better burn would be had with smaller fuel, or more fuel.
