### APPENDIX 8.3. LCC AND PBP RESULTS USING ALTERNATIVE INSTALLATION COST SCENARIOS

8.3.1 INTRODUCTION This appendix presents life-cycle cost (LCC) and payback period (PBP) results using alternative installation costs for non-weatherized gas furnaces and gas boilers. These results are presented as high and low sensitivity cases. For non-weatherized gas furnaces, DOE used two alternative sources: a 1994 Gas Research Institute (GRI) report, and data from Natural Resources Canada (NRCanada) (see Chapter 8 for references). For gas boilers, DOE used the GRI report as an alternative source.
