Thermal and Environmental Analysis Solar Water Heater System for Residential Buildings

Due to the reduction of fossil resources, replacement renewable energy sources such as solar has become mandatory. Solar does not contain pollution and widely available in all parts world, especially warm regions. Our country (IRAN) is geographically located a hot dry region, with more than 280 sunny days per year, one nonpower applications heating space water consumption building using thermal energy. heaters can be used heat buildings, which main purpose this study. Water consumes an average 20% 30% total residential building. Therefore, annually provide 70% needed for heating. The system designed research able 75% needs. If auxiliary source next system, needs met throughout year. In case, much 237.3 kWh, will saved from sources.
