Active Solar Water Heating Alyssa D’Addezio and Nicole Ramsey
Goal of Technology • Efficiently heat water in homes • Renewable technology http://img.en.china.cn/0/0,0,271,17894,695,600,129c3ecc.jpg • Cost effective heating systems • Saves energy during summertime
Technology Potential • Reduction of air pollution • Decreased emission of greenhouse gases • Generates electricity http://wheresmyamerica.files.wordpress.com/2007/08/smoke-stack1.jpg
Operations • Flat-Plate Collector • weatherproof boxes with dark absorber plate to collect sunlight http://www.flasolar.com/active_dhw.htm • Integral Collector-Storage Systems • uses tubes and tanks to take warm water heated by flat plate collector to conventional back-up water heater • Evacuated-Tube Solar Collectors • glass tubes that inhibit radiative heat loss
Technological Obstacles • Needs warm climate with large amounts of sun and rarely freezes • No sunlight = No warm water • Solar plates are expensive and fragile
Political and Economic Obstacles • Expensive installment and repairs throughout the entire system • Government regulation and neighborhood covenants
Environmental Impacts • No negative environmental impacts • The solar water heating for the home drastically reduces a family’s utility bills and environmental impact. • During the winter, the solar heater eliminates the air pollution created by using traditional heating systems. http://fennerschool.anu.edu.au/studying/postgrad/environment/fenner_clouds.jpg
