Compact pressurized solar water heater work with heat pipe:
1. The material of inner tank is SUS304 2B (food grade) with 1.2mm thickness. All machine welding.
2. The material of outer tank is SUS304 2B with 0.4mm thickness.
4. The material of stand frame is stainless steel with 1.2mm thickness or Aluminum alloy with 2.0 thickness.
5. The thickness of polyurethane foam is 55-60mm.
6. It uses heat pipe to transfer heat energy, there is no water in the vacuum tubes, and it can be used in all climates.
7. Automatic water supply, could supply water self-acting without any other installation and could able to be pressured.
