Abstract
The invention discloses an auxiliary heating type solar water heater. A flat-plate solar collector is used as a main heat source, flue gas waste of a domestic honeycomb coal stove is used as an auxiliary heat source, and a low-temperature phase-variable heat-conducting medium is used for heat transferring. A heat collection portion of the flat-plate solar collector serving as the main heat source consists of a heat collection plate and a snakelike bend pipe, the snakelike bend pipe is communicated with a heating tank through a pipeline and filled with the heat-conducting medium with the boiling point ranging from 25 DEG C to 35 DEG C, and heat of the heat collector is transferred by means of vaporization and liquefaction of the heating-conducting medium. Flue gas waste of the domestic honeycomb coal stove is recycled to be used as the auxiliary heat source for heating the heat-conducting medium so as to supply heat for a water tank.
