The utility model relates to a solar two-in-one water heater. The water heater is provided with a cold and hot combination pipe fitting. The cold and hot combination pipe fitting is provided with a hollow square tube. The four side edges of the square tube are each provided with a cold water inlet tube of a solar heat collection plate. A special-shaped tube is arranged in the center of the square tube. A hot air outlet pipeline of an air heat source pump is formed between a cylinder and the inner wall of the square tube. According to the solar two-in-one water heater, by means of the cold and hot combination pipe fitting specially designed, in the using process, four hot water pipelines are sequentially connected in series to form a communicated pipeline so that hot water in a hot water storage tank of a terminal can be directly circulated when the water heater is not used, a cold water inlet pipeline can be preheated, electrical heating strips can be used for electrically heating the hot air outlet pipeline, for further utilizing heat energy, the cold water inlet tubes of the solar heat collection plate are arranged on the four side edges of the square tube and can have the preheating function, the heat absorption efficiency is improved, energy of all links is fully utilized, and the energy-saving purpose is achieved.
