Background technique

Solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet people's hot water use in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat-panel solar water heaters according to their structural forms, mainly vacuum tube solar water heaters, occupying 95% of the domestic market share. Vacuum tube type household solar water heater is composed of heat collecting tubes, water storage tanks and brackets and other related parts.
