  1. 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.

  2. Test Homes Test Home #1 Wood Siding Test Home #2 Brick Siding Simple Rectangular 45’x45’ Home

  3. Problem Setup (Walls and Roof) INSIDE: (Tin)= 70oF h=3 4” Fiberglass Insulation k2=.0107 W/ft*K 1/2” Gypsum Board k1=.052 W/ft*K 2x4” Wood Studs 16” on-center k3=.0366 7/16” Plywood Sheathing k4=.0168 .05” TYVEK Homewrap k5=.008 OUTSIDE: (Tout)= ? h=20 4” Masonry Bricks k6=.22 or 3/4” Wood Panels k7=.0366 or 1/8” Rubber Shingles (for roof) k8=.04 Aw (total) = 2552 sq. ft. (Walls) Ar (total) = 2150 sq. ft. (Roof) qloss

  4. Problem Setup (Floor) INSIDE: (Tin)= 70oF h=3 3/4” Floor Board k1=.0366 W/ft*K 8” Thick Cement Slab k1=.335 W/ft*K Ground Temp: (Tout)= 40 Ground Constant Surface temp of 70oF Af (total) = 2000 sq. ft. (Floor) qloss

  5. Calculations & Solution Solve for Outside Temperature!

  6. Results & Conclusions Excel Spreadsheet This claim would only be true in FLORIDA!!!
