Split Pressurized Active Close Loop Solar Thermal Water Heater System

Working Principle:It is close loop active system. The system include three main part: Solar collector, Pump working station and Water storage tank..It adopt the temperature difference circulationThe circulation pump transfer heat from Solar collector to water storage tank.We fix a △T  by the controller. When T1-T2≥△T,the controller will automatic let pump start circulate,Until the T1-T2
