The invention discloses an energy saving method using an electric boiler to provide gas for ironing equipment; the ironing equipment is provided, and connected with the electric boiler; the electric boiler comprises a heating furnace and an insulation furnace connected with the heating furnace; the ironing equipment comprises an ironing plate and an evaporation container; a steam pipe is arranged between the evaporation container and the ironing plate; heat conductive fluid is placed in the heating furnace and heated; the heated heat conductive fluid is conveyed to the evaporation container, so the evaporation container is heated up; the water in the evaporation container is heated and evaporated, and the steam is conveyed to the ironing plate through the steam pipe so as to iron clothes; after heat exchange with the heat conductive fluid, the steam returns to the insulation furnace for insulation; when the heat conductive fluid in the heating furnace is reduced, the heat conductive fluid in the insulation furnace is conveyed to the heating furnace for reheating. The energy saving method is high in thermal efficiency and less in pollution.
