Split pressures solar water heater

Split pressures solar water heater install on flat roof,The split and presures solar water heater composed by heat pipe vacuum tube collector,pressures storage tank,controller,working station.The split Solar Heating System is specially designed for residential house and building. Such system separates the solar heat collecting unit and the water tank. The collector can be installed at the sunny facet of a building, such as roof ot side wall. The water tank then can be installed in house with convenience. This makes it possible and easier to install the system aesthetically with original building.Working Principle:The pressure pump connects the circulation system between the Solar Heat Absorption Collector and the Water Tank. When the temperature difference between them reaches the trigger point,the system automatically starts circulation and naturally provides the heating water.Features :Module Design with flexible system configuration. Easy installation and integration with existing building. Intelligent control of the system operation with the system temperature monitoring. Dual Anti-Freeze Protections with thermal media in the circulation pipe and anti-freeze circulation control. Possible to integrate with current heating system (electric or gas baesd) to a hybrid system to provide water heating and floor heating system. Go Green on Sunny Day. Take the full advantage of Mother Nature to enjoy free heating. Specifications:The system includes:Pressurized Solar Collector, Water Tank, Working Station and Controller. Operating Pressure:0.6Mpa. Thermal Efficiency:≥55% in Summer, ≥45% in Winter. Thermal Loss:≤4% Assistant Electric Heating: 1.5KW-2KW Anti-Freeze:-35°C.
