The Seven SS Stars 150 Liters Non-Pressurized Solar Water Heater is a system designed to harness solar energy to provide hot water for various domestic and commercial applications. The system has a total capacity of 150 liters, which refers to the volume of hot water it can store once heated by solar energy. This capacity is suitable for small to medium-sized households or commercial establishments with moderate hot water requirements. Unlike pressurized systems, which use a pump to increase water pressure, this system relies on natural convection to circulate water between the collector and the storage tank. The system includes solar collectors, typically mounted on the roof or in a location with optimal sun exposure. These collectors absorb solar radiation and convert it into heat energy, which is then transferred to the water circulating through them. The system features a storage tank where the heated water is stored for later use. The tank is usually insulated to minimize heat loss and maintain water temperature. The tank and other components are typically made of corrosion-resistant materials such as stainless steel or coated steel to ensure durability and longevity, even in harsh environmental conditions. Some models may include a heat exchanger, which transfers heat from the solar collector to the water in the storage tank. This ensures efficient heat transfer and optimal performance of the system. The system may include temperature sensors and controls to regulate water temperature and prevent overheating. This ensures that the water remains at a comfortable temperature for use while maximizing energy efficiency. While primarily powered by solar energy, some systems may include a backup heating element (electric or gas) to provide hot water during periods of low sunlight or increased demand. This ensures continuous hot water supply regardless of weather conditions. The system requires professional installation, typically by certified technicians familiar with solar water heating systems. Proper installation is essential to ensure optimal performance and safety. Manufactured by Seven SS Stars, a reputable company specializing in solar water heating solutions.
