Analytical Validation of Commercial Wood-Burning
Stove Performance
By Troy Nietschmann and David Garrett
OBJECTIVES 1.Determine outside Temperature
conditions that this 29.3 kWatt wood-burning
stove would maintain an inside equilibrium
temperature of 70oF for two unique 2000 sq. foot
homes. 2. Determine whether this claim is
reasonable.
