the method comprises the following steps: an external water source is conveyed to a water return pipe (123) through a water inlet pipe (124), the water source is sequentially conveyed to each heat collection header (121) through the water return pipe (123), and water in the heat collection headers (121) flows into heat collection pipes (122) to collect heat;

step two: the hot water heated by solar energy is conveyed into the water storage tank (4) through the water outlet pipe (125), the temperature sensor in the water storage tank (4) detects the water temperature, and when the water temperature is lower than a set temperature, the water is heated through the heating wire (22) to store the water in the water storage tank (4) in a heat preservation way;

step three: warm water in the storage water tank (4) passes through the pipeline and carries to hanging stove (31), carry warm water to main heat exchanger (32) through circulating pump (34), when thermodetector detects cold water pipe (341) inside temperature and is less than the settlement temperature, gas valve (38) are opened, ignition needle (332) are lighted the fire row (331), heat the water in main heat exchanger (32), reach behind the settlement temperature, water in main heat exchanger (32) passes through hot-water line (321) and exports to heating equipment, when thermodetector detects cold water pipe (341) inside temperature and reaches the settlement temperature, water in main heat exchanger (32) directly exports to heating equipment through hot-water line (321).
