Galvanized Steel Solar Water Heater

Introduction:
The non-pressurized solar water heater (solar geyser) is based on the natural circulation thermosiphon phenomenon. It’s the most cost-effectiveness and environmentally friendly way to harness solar energy for hot water applications, which is unsurpassed by any other solar thermal products, for its most high efficiency, low cost and easy installation.
Galvanized steel non-pressure solar water heater characteristic:
1. Adopt most economic material (outer tank and support).
2. Most reliable, cost saving, efficient hot water heating solution.
3. Simple structure, easy installation, labor cost saving.
4. Automatic operation with intelligent controller.
5. Low maintenance cost.
