Detailed Product Description

Stainless solar water heater is a kind of compact system of solar collector and water storage tank. The whole system relies on the different density of cold water , thus non-pressure solar water heater also called thermal-siphonal solar water heater.

The system can work without the circulation pump and no heat pipe connection. Cold water directly filled into the vacuum tubes, the vacuum tubes gather energy and heat the cold water, the lighter hot water tand and cold water come down them be reheated. That how the water do circulation by itself.

Non-pressure solar water heater system is most economical and suitable products for low latitude countries and regions, especially for Asian, Africa, Oceania, South America and South part of North America.

Optional accessories: controllor and electrical heater.
