Solar water heating devices are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, mainly vacuum tube solar water heaters, which occupy 95% of the domestic market share. A vacuum tube household solar water heater is composed of a heat collecting tube, a water storage tank, brackets and other related spare parts. Converting solar energy into heat mainly relies on the vacuum heat collecting tube.
