The invention relates to the technical field of water heaters, in particular to a high-performance
solar water heater which comprises a first pulling mechanism, a cable body, a second pulling mechanism, a support mechanism, a liquid adding mechanism, a mixing mechanism, a spraying mechanism and an
air drying mechanism. According to the high-performance
solar water heater provided by the invention,dust on an outer wall of each heating
pipe can be removed simultaneously through a dedusting mechanism, so that the blockage on an outer wall of each heating
pipe is reduced, the heat absorption performance of each heating
pipe is higher, and a
heating effect is improved; water scales on inner walls of the heating pipes can be scraped and flushed out through water, so that
heat energy of sunlightreceived by the heating pipes can be effectively conducted into water, the
heating effect is further improved, and the high-performance
solar water heater is safe, simple and convenient to operate; when a user does not use the high-performance solar
water heater for a long time, protection plates can cover on the heating pipes, so that the heating pipes are protected and are prevented from collecting dust; and the heating pipes can rise in summer, so that the heat
absorption capacity of the heating pipes is reduced, the heating pipes are prevented from being located at high-temperature high-pressure state for a long time, and the service life of the heating pipes is prolonged.
