Disclosed is a multilayer heating type boiler which heats water step by step through heat exchange while a heating tank is divided into several tanks and a hot water pipe successively passes through each heating tank to heat the heating tank to a predetermined temperature by a separate heater. As the multilayer heating type boiler has a structure where hot water is gradually heated to a desired temperature by the circulation of the hot water around heating tanks, the volume of each of the heating tanks can be reduced. The amount of heating medium oil to be heated in each of the heating tanks can be reduced. Energy used for heating the heating medium oil is reduced to improve the heat efficiency. |
