Separate Pressurized Closed Loop Solar Water Heating System breaks through the traditional structural design, that is collector and water tank are separated, that is the tank can be put anywhere, so model is more convenient and handsome. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller. Features: 1) Pipeline is made of all red copper and conducted by heat transfer medium liquid 2) Water isn't flow in the vacuum tubes and is operated when confined 3) Aluminum alloy mould material of high strength with airflow design 4) It is furnished in good style; It is furnished in good style 5) Tank is equipped with electric water heater setting, automatic temperature controller 6) With increased anode magnesium bar stick to prevent furring. 7) The insulating layer uses polyurethane bulk bubble 8) It successfully carries out installation of separation according to fabricating yard Detailed Specification: Solar tank 1.
