The "Seven Stars 200L pressurized heat-pipe solar water heater" 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.Pressurized: Pressurized solar water heaters are designed to operate under pressure, providing consistent water flow and pressure similar to conventional water heaters. These systems are suitable for households with high hot water demand or where the water pressure is low.Heat-Pipe Collector: This system uses heat pipe solar collectors to absorb sunlight and convert it into heat energy. Heat pipe collectors consist of evacuated tubes containing a heat-absorbing plate and a heat pipe that transfers heat to the water circulating through the collector.Solar Water Heater: The solar water heater system typically consists of the following components:Heat pipe solar collectors: These collectors are usually installed on the roof or in an area with ample sunlight exposure.Storage tank: A pressurized tank to store the heated water for later use. In this case, the storage tank has a capacity of 200 liters, suitable for residential use.Circulation system: Pipes and pumps to circulate water between the collector and the storage tank under pressure.Controls: Temperature and pressure controls to regulate the operation of the system and ensure safe and efficient performance.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 medium to large households with higher hot water demand.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 proper insulation of pipes and storage tank.Overall, the Seven Stars 200L pressurized heat-pipe solar water heater offers a reliable and efficient solution for residential hot water needs, utilizing solar energy to reduce energy costs and environmental impact while providing consistent hot water under pressure.
