Active Solar Water Heating Alyssa D’Addezio and Nicole Ramsey

Goal of Technology  Efficiently heat water in homes  Renewable technology  Cost effective heating systems  Saves energy during summertime

Technology Potential  Reduction of air pollution  Decreased emission of greenhouse gases  Generates electricity

Operations  Flat-Plate Collector weatherproof boxes with dark absorber plate to collect sunlight  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. clouds.jpg
