PURPOSE: A boiler system for heating and hot water supply is provided to use the heat of a thermal medium in an expansion tank completely for heating heat-storage water in a heat-storage tank by embedding the expansion tank in the heat-storage tank. CONSTITUTION: A boiler system for heating and hot water supply comprises an expansion tank(1) and a heat-storage tank(6). The expansion tank circulates and stores a thermal medium heated in a solar collector(2) through a thermal medium heat exchanger(4). The heat-storage tank is filled with the heat-storage water heated by the thermal medium while circulating a heat exchange coil(5). The solar energy heats the cold water in a water supply pipe(45) and supplies the heated water to a hot water outlet valve(15). When the cold water in the water supply pipe is circulated to a hot water supply heat exchange coil(13), the heat-storage water in the heat-storage is reverse-circulated to a hot water supply heat exchanger(7). |
