New advancements in wall furnace technology can bring substantial energy savings, emissions reductions, and indoor air quality improvements to multifamily apartments and other small dwellings.

GTI Energy recently completed a project for the California Energy Commission to characterize baseline emissions and energy efficiency of wall and floor furnaces in California homes, then developed and demonstrated retrofit packages with payback on incremental costs within the life of the technology.

This presentation will review results from laboratory testing and field monitoring of existing baseline and new efficient wall furnaces, and give practical information about how to obtain, install, and operate efficient wall furnaces to improve performance.
