GTI is addressing key challenges in bringing new technologies such as high-efficiency water heaters, combined space and water heating systems, furnaces, natural gas heat pumps, and advanced heat recovery systems to market—by bridging the gap between development and full commercial introduction.
Technology and market assessments are being performed on a variety of space conditioning and water heating equipment to enhance the competitiveness of gas-fueled equipment and allow consumers to take advantage of the fuel-cost savings. Researchers are evaluating technologies with the potential to provide significant emissions reductions and modeling equipment performance to compare against electric options for life cycle and operating costs, source-energy use, and greenhouse gas emissions.
Individual residential water heater projects focus on developing high-efficiency, low-emissions burners to reduce first costs in condensing gas water heaters and various components for gas-heat-pump water heaters.
Field demonstrations on combined space- and water-heating systems are providing performance data for evaluation and to guide future product improvements and developments.
Researchers are investigating issues associated with the use of condensing-furnace technology to develop a rooftop high-efficiency gas packaged air conditioner (gas PAC) that combines gas heating with electric cooling to provide energy savings for consumers in the commercial sector.
GTI has also created a Guide to Best Practices for Home Energy Retrofits sponsored by the California Energy Commission.
