A multipurpose boiler is provided to diversify heat mediums and reduce installation cost by forming a vapor tank and a hot water tank for selectively or simultaneously heating vapor and hot water. A multipurpose boiler comprises a heat exchanger using an accumulated heat medium(13), a vapor tank(23) and a hot water tank(24), a vapor header(27), and a hot water utility(29) and an expansion tank(30) installed at the hot water tank. The heat exchanger using the accumulated heat medium circulates an accumulated heat medium heated by a main body(10) to have the main body and a closed circuit. The vapor tank and the hot water tank are installed at an inlet(22) and an outlet(21) of a heat exchanger(11) with supply pipes(25a,25b) and returning pipes(26a,26b) to generate vapor and hot water selectively. The vapor header is placed at the vapor tank with a vapor supply pipe(28a) and a condensed water returning pipe(28b). |
