The "Seven Stars non-pressurized solar water heater 200 liters" refers to a specific type of solar water heating system designed to provide hot water using solar energy. Here's what you need to know about this system:Brand: Seven Stars is the brand name of the solar water heater. Different manufacturers may produce solar water heaters under this brand name.Non-Pressurized: Non-pressurized solar water heaters are typically used in applications where low-pressure hot water is sufficient. These systems rely on natural convection to circulate water between the collector and the storage tank. They are often used in residential settings and are more straightforward in design compared to pressurized systems.Solar Water Heater: This system utilizes solar energy to heat water. It typically consists of the following components:Solar collector: A flat-plate or evacuated tube collector absorbs sunlight and converts it into heat, which is transferred to the water circulating through the collector.Storage tank: A tank to store the heated water for later use. In this case, the storage tank has a capacity of 200 liters, allowing for the storage of a significant amount of hot water.Circulation system: Pipes and pumps (if necessary) to circulate water between the collector and the storage tank.Controls: Optional temperature and pressure controls to regulate the operation of the system.Capacity: The system has a storage tank capacity of 200 liters, meaning it can store up to 200 liters of hot water for use. This capacity is suitable for residential use, providing enough hot water for daily needs such as bathing, washing dishes, and laundry.Efficiency: Solar water heaters are known for their energy efficiency and environmental friendliness since they utilize renewable solar energy to heat water, reducing reliance on fossil fuels.Installation: Proper installation of the system is essential to ensure optimal performance and longevity. Installation considerations include the orientation and tilt angle of the solar collector, plumbing connections, and insulation of pipes and storage tank.Overall, the Seven Stars non-pressurized solar water heater with a capacity of 200 liters offers a reliable and eco-friendly solution for residential hot water needs, utilizing solar energy to reduce energy costs and environmental impact.
