split pressurized solar water heater

split pressurized solar water heater:work principle:Integrative heat-pipe type solar system is composed of three components --- pressured heat storage water tank, vacuum heat collector (a cooper-tube style heat pipe inside) and support. Working principle: when the temperature of the solar collector reaches the set value, the controller shall start the circulation pump automatically. the circulation pump makes media liquid circulate automatically. The media liquid tranfers heat to water by the heat exchanger in the water ttank. In case the temperature of the circulation pump does not reach the setted value , the circulation pump shall be stop working automatically. In case the temperature of the water tank does not reach Tmax, then start the electrical heater.. 1)Water tank (interior): porcelain enamel 2) manifold: aluminumalloy 3) Glass tube: new trivalent element heat tube 4) Solar working station 5) Steel tube dimensions: 58mm x 1.8m 6) Water capacity: 150L, 200L, 300L 7) Pressure:10 bar
