split pressure solar water heater being described belows:
Operating principle: split pressure 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 temperature is below30°C, auxiliary heating system will automatically fill to 30 °C automatically cut off the power.
Feature: Achieving collectors and thermal storage separation installation, enabling multi-storey residential and high-rise residential use of solar water heaters will be installed at every household. All copper flow channel, vacuum tube heat conduction inside the media do not take the water, under pressure to run antifreeze function better, at minus 30 to minus 40 degrees to work streamlined design, beautiful and generous standard electric heating equipment, automatic temperature control
