Solar thermal water heating systems can be combined with demand water heaters, as well as radiant floor heating, to create an energy efficient system in residential homes, according to this document from Chandler Design Build.
This report from the Southwest Gas Corporation explores the use of natural gas as a backup for solar thermal water heating systems. Three different system setups are discussed and diagramed as the best options for utilizing a solar thermal natural gas combination system.
This presentation, given by vA Consult, focuses on two new European directives: the Ecodesign and the Energy labeling. Both will have an impact on solar-energy based products such as space heaters and combi-heaters as well as water heaters and hot water tanks. The presentation gives a good overview of what the labeling system would involve, and a timeline for its implementation. An eco-label is being developed within the EU for water heaters which will show the energy efficiency of the package or product.
This report was published by the State of Hawaii’s Department of Business and Economic Development and Tourism (DBEDT). It provides a comprehensive overview of the status of solar thermal water heating systems in Hawaii since the beginning of the state’s tax credit for solar systems in 1977.
This case study from Skyline Innovations, Inc. discusses a rooftop solar thermal water heating system for a 267 unit high-rise multifamily building in Washington, D.C. The system was installed and is operated under a price-indexed power purchase agreement and is being used to offset the building’s use of natural gas.
New York is one of the top five states in the U.S. for solar thermal water heating systems. Bright Power, Inc. set out to test different solar thermal systems in various regions of New York to determine which system perform the best in each locale. This presentation shares the results of their research.
