Researchers from Oak Ridge National Laboratory have developed a free, web-based application that calculates the savings and energy efficiency of residential ground-source heat pumps compared to gas heating.Scientists at Oak Ridge National Laboratory (ORNL), which is funded by the US Department of Energy, have created a free web-based tool that estimates the benefits and implementation costs for ground-source heat pump installations in buildings in the United States. The tool was designed to allow building owners, heat pump system designers, and installers to estimate the efficiency and cost savings ...Den vollständigen Artikel lesen ...
