Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form, with vacuum tube solar water heaters being the main type.

[0003] The vacuum tube household solar water heater is composed of related parts and components such as collector tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes. The vacuum collector tubes use the principle that hot water floats and cold water sinks to create microcirculation of water and obtain the required hot water.
