Design and Construction an Efficient Solar Water Heating System for Building Heating Purposes

Abstract

Solar water heating systems (SWHS's) is the technology of the most important applications used for energy-saving in renewable energy. A solar water heater system (SWHS) constructed for building heating consists of solar panel (vacuum tube type) absorber with different heat radiators are used as a closed-cycle system to heat a room with dimensions: (7x7x3) m. The maximum heat transfer depends on the temperature difference between the external ambient and the room temperature, liquid flow rates, and the radiator material type. The results show that the radiator made of aluminum material is more efficient than that radiator made of iron material, so that, it can be utilized for building heating.
