Ladder-shaped temp-rising solar water heater

The utility model relates to a heating device, particularly a ladder-shaped temperature-rising solar water heater. The ladder-shaped temperature-rising solar water heater is mainly composed of a ladder-shaped water tank, the circulation assistance device of the heating power, the vacuum tube of the solar energy, a concave refractive lens, the outlet of the hot water pipe, the water outlet of the water heating, a parallel water inlet, and an integral bracket. The ladder-shaped temperature-rising solar water heater which is on the focus of the solar energy combines and uses less electric energy. Accordingly, hot water can be continuously output and used; the ladder-shaped temperature-rising solar water heater can also replace a small-size boiler for heating in winter; mineral resources are saved, and environment pollution is reduced.
