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.
