The invention belongs to the technical field of heat treatment and equipment, and relates to a heating device, in particular to a vertical wall-mounted non-water-tank
solar water heater. According tothe vertical wall-mounted non-water-tank
solar water heater, an outer shell of the vertical wall-mounted non-water-tank
solar water heater is in a hollow cuboid with one opening surface. A buffering layer covers the outer shell. A
toughened glass plate is located on the opening surface of the outer shell, and a cavity structure is formed. A glass cavity is of a whole
glass structure, is located inthe cavity structure, and includes a vacuum cavity, a vacuum glass endothermic cavity, a heat conduction liquid cavity and a
water storage cavity which are each of a cavity structure. The glass cavity further comprises a blue
film coating sprayed and coated in the vacuum glass endothermic cavity. The vacuum glass endothermic cavity is adjacent to the
toughened glass plate. A water inlet and a water outlet penetrate from the outer shell into the
water storage cavity. By means of the vertical wall-mounted non-water-tank solar
water heater, vertical installation can be achieved, the
water storage capacity is high, an additional water tank is not needed, installation is more convenient and efficient, the
glass structure is low in cost and easy to
machine, the
thermal efficiency is high, the service life is long, the inner part structure is stable, the water outlet quality is high, and low-level installation can be achieved.
