The utility model relates to a living facility, in particular to a solar-energy automatic control heating multi-preventing water heater. The utility model is composed of a water tank, a water pipes, a heat collector, and two branches of water pipes of the water tank are respectively communicated with the inlet opening and the outlet opening of an indoor heater. An indoor water tank (9) which can store the heat and adjust the temperature is connected on a heating loop, an automatic temperature controlling circulation pump (13) is also installed on the heating loop, and the problem of solar-energy heating in winter is solved. In addition, a water heater (10) is arranged inside the indoor water tank (9), and therefore living hot water can be produced. A heat preservation hood is adopted to be mutually connected with a roof gas exhaust hole in the open air, and a pipeline is frozen through the residual heat of indoor waste gas. The indoor water tank is connected with the hanging solar-energy heat collector, and the heating capability is enhanced. A solar-energy air-conditioner connector is additionally arranged for refrigeration to prevent sunstroke, and the heat exchanger of an air (water) source heat pump is additionally installed, to utilize shallow geothermal heat or the residual heat of an enclosed balcony. The function of the facility is complete, the performance is reliable, the utility model has the characteristics of convenient material selection, inexpensive construction cost, simple operation, and secure running, etc., the power saving effect is remarkable, and the application prospect is considerable.
