solar water heater with glass tubes (Evacuated Tube Collector) works by trapping sunlight through double-layer glass and using a vacuum to lock in heat.How the Glass Tubes WorkDouble Glass Layers: Each tube has an outer glass tube and an inner glass tube made of strong borosilicate glass.Vacuum Insulation: The air between the two glass layers is removed to create a vacuum. This vacuum stops heat from escaping back into the air.Solar Absorption: The inner glass tube has a special dark coating that absorbs sunlight and turns it into heat very quickly.
