split pressurized Solar Water Heater

Split pressurized Solar Water Heater: Operating principle: split pressurized solar water heater system uses temperature controlled forced circulation. When the solar collector temperature is higher than circulating water tank temperature setting, the system automatically starts circulating pump, the collector row back in the hot water cycle of water tanks, water tank and circulating water temperature routed to the collector; when the a balance between the water temperature, the circulation pump stopped working, so the work back and forth in order to achieve the purpose of heating water tank circulation (circulation pump for intermittent work), so that the use of intermittent work have unrestricted access to the water temperature continues to rise, more efficient use of solar energy ; sunlight conditions are not good enough, the system can set the time automatically detect the circulating water tank in the water temperature, if the water temperatureis below30°C , auxiliary heating system will automatically fill to the30 °C automatically cut off the power. specification: 1.inner tank:stainless steel SUS 304-2B,thickness:1.2mm2.outer tank:galvanized steel plate ,thickness:0.55mm 3. vacuum collector tube: heat pipewtih alluminum fin,SS-C/CU(three target)4. collector tube size: ø58mm x 1800m ,ø47mm x 1500mm 5.
