Product Overview
These Non-Pressure ETC Solar Water Heater rely on the natural circulation of water between the collector and the tank. As water in the evacuated tubes is heated it rises naturally into the tank, while cooler water in the tank flows down to the bottom of the evacuated tubes, causing circulation throughout the system. So once and once again, all the cold water will be heated gradually and become hot water. Features: a Inexpensive solution, high reliability, simple structure, easy installation. a High efficiency with daily average efficiency higher than 60%. a Auxiliary electric heater (1500W) and controller are optional. Product Specifications 1) Inner tank: Stainless steel SUS304-0.5mm 2) Vacuum tube: 47mm*1500mm/58mm*1800mm,high borosilicate glass 3.3, three targets coating,outer tube 1.8mm thickness. 3) Outer tank: Painted steel-0.4mm/aluminum-zinc coated steel-0.45mm 4)insulation: Polyurethane 50mm 5) Frame: Coated galvanized steel-1.5mm 6) Reflector: Aluminum component/stainless steel Models: TZ47/1500-**(tubes quantity) ,90 LPD~300LPD TZ58/1800-** (tubes quantity),100LPD~300LPD
