304 Mirror Gravity-fed Non Pressurized Vacuum Tube Solar Water Heater with 200Liter Tank
Working principle:
The series employs the natural convection phenomenon called “thermosyphon”.
The evacuated tubes convert solar energy into heat energy and transfers heat to water.
The lighter hot water in tubes rises to the storage tank, while the cold water at the bottom of the tank flows into the tubes, creating continuous circulation.
The convection flow will continue as long as the sun is heating the collector.
Specifications:
Thermosyphon solar water heater with CE certificate, strong frame, golden color shape,
Integrative thermosyphon solar heating system is a low pressure solar water heater which provides basic hot water demand.
This system relies on the natural circulation of water between the collector and the tank.
As water in the vacuum tubes is heated it rises naturally into the tank, while cold water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system.
Features:
1. It is non-pressurized thermosyphon solar water heater with water tank, and is economical as a natural circulation system.
2. The material of inner tank is SUS304 2B food grade stainless steel with 0.4mm thickness.
3. The material of outer tank is SUS304 stainless steel with 0.4mm thickness.
4. The material of stand frame is stainless steel with 1.2mm thickness. The angle of the frame can be changed in the production as the local latitude of customers, we can design the suitable angle for the customers. We also could provide the adjustable frame.
5. The thickness of polyurethane foam is 55-60mm.
6. It uses vacuum tubes, the water could be heated in the tubes directly.
7. It is very popular in torrid zone and warm area, such as Asia, Africa and etc.
8. The installation and maintain is very easy.
9. We offer the accessories of this system, such as electric heater, assistant tank, controller, magnesium and etc.
10. Capacity from 50L to 500L
11. Passed EN12976 standard testing in Europe
