- Glass lining – is a material made by fusing powdered glass to the inner surface of the metal tank by firing between 850 °C to 870 °C. Molecular interaction results in a coating that melts flows and then hardens to a smooth, durable glass coating on the metal surface. So that glass and steel can not be separated from each other. Glass lining provides superior longevity to a hot water tank. In certain areas, stainless steel tanks tend to fail more rapidly than glass-lined tanks due to chlorides in the water, and Hence This solar water heater is much more advisable than the normal stainless steel or copper solar tanks.
