Pre-Heated Pressurized Solar Water Heater Specifications: 1. Inner tank material: Stainless steel 304 2B food grade / 316 : 0.4-0.6mm 2. Insulation: Imported Polyurethane total forming with pressure and best density 40kgs/M3 50-60mm 3. Outer sheet: Aluminum galvanized sheet/color steel sheet / Stainless steel: 0.4mm 4. Frame: Aluminum galvanized steel sheet folded from mould with power painting / Stainless steel / Aluminum Alloy 1.2-2mm Note: 1.with heater exchanger 12mm,max.pressurized 8bar; 2.state water supply direct enter into the inlet water hole, go through the heat exchanger hot water come out from the outlet water hole; 3.the air vent hole can connected with central heat supply pipe to heat the tank water Feature: 1) Use at any time: It adopts advanced design idea and integrates with high efficiency pre-heated patent technique, so it can warm the cold water rapidly when it flows through special pipe. It can overcome the demerit of traditional solar water heater, such as slow heating, long waiting time. 2) Instantaneous heat exchange plentiful hot water: high pressure and fresh hot water runs down simultaneously with tap open. 3) Multi-functional thermosiphon solar water heater with copper coil heat exchanger, it can provide hot water and room heating simultaneously. 4) Lower working noise and longer life: patent concentric coil design greatly reduced the damage to the inner tank caused by the shake when water flows though the coil. 5) Economical and Environmental protecting: There is no pollution when it is working since it depends on sunshine. 6) Easy operation: it can supply water automatically, you can take it easy and enjoy your time.
