DOE Report: Residential Ground Source Heat Pumps with Integrated Domestic Hot Water Generation

Energy Efficiency and Renewable Energy ~ As part of its work under the U.S. Department of Energy's Building America Program IBACOS collaborated with Pine Mountain Builders to build two houses in Pine Mountain, Georgia. The project was designed to document the installed operational space conditioning and water heating efficiency of the houses’ GSHP systems. The topics researched for energy improvement were:
—Ground source heat pumps (GSHPs) to substantially reduce energy.
—Desuperheater to generate domestic hot water for reducing energy consumption.
